From 2008 to 2010, 11 patients (aged 19 to 29 years) with mandibular deficiency underwent intraoral or extraoral inverted-L osteotomy of ramus and lilac crest bone grafting. Data were collected from the patients' records, photographs and radiographs. The height and width of the ramus were successfully expanded by inverted-L osteotomy and lilac crest bone grafting with minimal complications in all patients, resulting in significant improvement in occlusion and facial appearance. Our early results showed that the inverted-L osteotomy of ramus and lilac crest bone grafting is safe and effective, and should be considered as a good alternative for the patients with mandibular deficiency.展开更多

Hip dysplasia may lead to arthrosis at an early age due to poor coverage of the femoralhead and abnormal loading of the joint articulation. In patients with symptomatic dysplasia and closed triradiate cartilage(generally over age 10), including adolescents and young adults(generally up to around age 40), the Bernese periacetabular osteotomy(PAO) is a durable technique for addressing underlying structural deformity. The PAO involves a modified Smith-Petersen approach. Advantages of the Bernese osteotomy include preservation of the weight-bearing posterior column of the hemi-pelvis, preservation of the acetabular blood supply, maintenance of the hip abductor musculature, and the ability to effect powerful deformity correction about an ideal center of rotation. There is an increasing body of evidence that preservation of the native hip can be improved through pelvic osteotomy. In contrast to hip osteotomy and joint preservation, the role of total hip arthroplasty in young, active patients with correctable hip deformity remains controversial. Moreover, the durability of hip replacement in young patients is inherently limited. Pelvic osteotomy should be considered the preferred method to address correctable structural deformity of the hip in the young, active patient with developmental dysplasia. The Bernese PAO is technically demanding, yet offers reproducible results with good long-term survivorship in carefully selected patients with preserved cartilage and the ability to meet the demands of rehabilitation.展开更多

In the present paper, we present a detailed review of previous studies of triple osteotomy as an alternative treatment for DDH. We also report our experience treating 6 adult cases of DDH by triple osteotomy in order to highlight the various aspects of this procedure.The mean age of our patients was 31.2 years with a mean follow-up period of 6 years. We assessed range of motion, center-edge angle, acetabular index angle, Sharp angle, acetabulum head index, head lateralization index, Japanese Orthopedic Association score, Harris hip score, patient satisfaction, and the difference between lower limb lengths before and after the procedure. At final follow-up, clinical scores were significantly improved and radiographic parameters also showed good correction of acetabulum.展开更多

Surgeries aimed at improving the biology, such as vascularized fibula grafting, have good success rates but require high levels of expertise and substantial resources. A popular surgical treatment aimed at improving the biomechanics-valgus intertrochanteric osteotomyoptimizes conditions for fracture healing by converting shear forces across the fracture site into compressive forces. Numerous variations of this surgical procedure have been developed and successfully applied in clinical practice. As a result, the proximal femoral orientation for obtaining a good functional outcome has evolved over the years, and the present concept of altering the proximal femoral anatomy as little as possible has arisen. This technical objective supports attaining union as well as a good functional outcome, since excessive valgus can lead to increased joint reaction forces. This review summarizes the historical and current literature on valgus intertrochanteric osteotomy treatment of nonunion neck of femur, with a focus on factors predictive of good functional outcome and potential pitfalls to be avoided as well as controversies surrounding this procedure.展开更多

T...Summary: Preoperative planning of corrective osteotomy with traditional radiography has limitations in regards to determining the ideal osteotomy location and orientation in three-dimensional femoral de- formities. Though a successful operation can be planned preoperatively, intraoperative contingencies might adhere to the procedural plan in the performance of operation. To efficiently perform a planned procedure, proposed is a design to implement three-dimensional reconstruction photography, based on computer-tomography (CT) scan. A custom-made guide was designed to navigate the osteotomy as planned, and additionally, a personalized intramedullary nail was used for fixation after osteotomy. Three-dimensional (3D) photography of deformed femur was established based on the CT dataset and transferred into 3D photography processing software for further planning. Osteotomy planes were de- signed and adjusted at deformity sites to correct the 3D deformities. The methodology of a custom-made osteotomy guide was introduced in femoral corrective osteotomy, for the first time, to navigate the op- eration as planned. After the virtual osteotomy and reduction of bone segments, the parameters of a custom-made intramedullary nail were measured for manufacturing. Findings Virtual operation in computer shows complete correction of the 3D deformity. The osteotomy guide, obtained by rapid-prototyping techniques, navigates mimicking surgery on rapid-prototyping model of the involved femur as planned. Internal fixation was achieved using the custom-made intramedullary nail. Interpreta- tion three-dimensional visualization introduces an advantage in preoperative planning for corrective os- teotomy of 3D femoral deformity, and the custom-made osteotomy guide is crucial to realize such a de- liberate plan during the actual procedures. The internal fixator, such as an intramedullary nail, can be modified or personalized for fixation in unique cases.展开更多

In the present study, we introduced a new way of osteotomy (Z-shaped) in treating humeral shaft nonunion secondary to failed plate osteosynthesis. Clinical data of 24 patients with humeral shaft nonunion following implant failure (from 2010 to 2014) were retrospectively evaluated. These patients underwent Z-shaped osteotomy in revision surgery after the initial surgery, plate osteosynthesis, was failed. Outcomes were evaluated using visual analogue scale (VAS) and Constant and Murley score. Repeated analysis of variance (ANOVA) was used for statistical analysis. Patients were followed up for a minimum of 24 months (26.83±4.33 months). The operative time was 102.33±10.16 min, and hospital stay averaged 9.75±2.13 days. All patients achieved clinical union at the latest follow-up. Complications included radial palsy (n=1) and superficial wound infection (n=1). The postoperative VAS scores decreased significantly compared to preoperative score (F=257.99, P<0.01). Constant and Murley score increased and reached 81.33±0.95 at 24 months' follow-up 0=247.35, P<0.01). Among all the cases, 15 cases were graded as "excellent", and 9 as "good". In conclusion, Z-shaped osteotomy was easy to perform, and it provided additional medial support with more bone contact areas. Revision surgery using locking plate and Z-shaped osteotomy achieved high union rate and improved functional outcome. It was a reasonable and safe option for treating humeral nonunion following implant failure.展开更多

Indications for application of acute total elbow arthroplasty (TEA) in the setting of distal humeral fractures are still being defined. A variety of factors including chronologic age, physiologic age, bone quality, presence of pre-existing arthritis and pre-existing medical conditions need to be considered. Optimally the decision to proceed with TEA verses open reduction internal fixation (ORIF) is made preoperatively. The need to abandon ORIF may be not be apparent until after fracture exposure, and the presence of an olecranon osteotomy makes performing TEA challenging. A case is presented of acute conversion from ORIF to TEA following olecranon osteotomy, utilizing internal fixation bridging the ulnar component and its cement mantle.展开更多

Posterior column osteotomies such as the facetectomy or Ponte or Smith-Petersen osteotomy provide the least correction, but can be used at multiple levels with minimal blood loss and a lower operative risk. Pedicle subtraction osteotomies provide nearly 3 times the per-level correction of Ponte/Smith-Petersen osteotomies; however, they carry increased technical demands, longer operative time, and greater blood loss and associated significant morbidity, including neurological injury. The literature focusing on pedicle subtraction osteotomy for fixed sagittal imbalance patients is reviewed. The longterm overall outcomes, surgical tips to reduce the complications and suggestions for their proper application are also provided.展开更多

Methods: Between June 2001 to July 2008, 18 patients with monocompartmental degeneration of the knee combined with a varus malalignment of the leg had the modified biplanar opening high tibial osteotomy and the osteotomy was fixed with the locking plates (Locking Compression Plate System). The mean varus deformity before operation was 11.5° (5°- 19°) and no degenerative changes were found in other departments. Stability of the knee was normal in 15 patients, but ruptures in anterior cruciate ligaments or lateral collateral ligament were presented in the remaining 3 patients. Preoperative symptom was mainly limited in the pain of medial compartment. The preoperative and follow-up data for the range of motion and Lysholm score were determined. Subjective satisfactory examination was also applied to the patients for the operation they selected. Results: All of the patients were followed up with an average of 32.5 months (12-82 months). There was no ununion or delayed union in this group during the follow-up period. No complications like broken plate, nerve injury, or blood vessel injury occurred. The postoperative average corrected degree was 9.5° (5.5°-18°). No degenerations developed in the three departments of the knee. The Lysholm scores before and after surgery were 42.5 and 77.5, respectively (P〈0.01). The overall fineness rate was 83.3%. The subjective satisfactory survey demonstrated that about 83.3% patients showed satisfactory on the operation. There was no obvious difference in the range of motion before and after operation, but significant changes were found in the Lysholm score and varus degree from preoperative to follow-up. Conclusion: Proximal opening high tibial osteotomy performed in conjunction with the special rigid locking plate yielded good results for symptomatic genu varum. This new classic technique can be effectively applied to the medial compartment degeneration of the knee in active young patients.展开更多

Autograft concern is further supported by authors who suggest the routine use of internal fixation. Problems such as graft extrusion, rotation and absorption, leading to loss of acetabular correction, were often noted in cases previously treated at our National Hospital for Pediatrics. This retrospective study reviewed the radiographic results of this treatment protocol in 106 hips developmental dislocated hips which met our inclusion criteria. The efficacy of this method to achieve and maintain a well covered and stable hip was the main objective of the study. Methods: This retrospective study reviewed the radiographs of 106 hips presenting with developmental dislocation which were treated by modified Salter’s innomiate osteotomy and using a fibular allograft as the interposition material. Dislocations of the hip were graded using the T?nnis system. Measurement of the acetabular index (AI) was the main variable. The minimum follow up period was 2 years. Possible complications such as loss of acetabular correction, hip redislocation, graft extrusion or resorption, the need for osteotomy internal fixation, delayed or non union, infection or avascular necrosis (AVN) were documented in this series. Results: Between January 2004 and December 2008, 106 surgeries were performed in 95 patients. Sixty-three (86.3%) of the patients were girls and ten (13.7%) were boys, thirteen patients (13.7%) were between twelve and eighteen months old at the time of the operation, the remaining eighty-two (86.3%) patients being between eighteen and thirty-six months old, with the mean age of 22.6 months at the time of surgery. There were eleven (11.6%) patients who had bilateral dislocation. Eighty-four (88.4%) patients were affected unilaterally. The right hip was involved in seventeen (17.9%) and the left hip in sixty-seven (70.5%) cases. T?nnis system Type 3 was in 34 hip (32.1%), and Type 4 was in 72 hip (67.9%). All patients combined open reduction and modified Salter’s innomiate osteotomy, inserting a fibular allograft as the interposition material. Acetabular index was improved, preoperation was 42.95°, and latest follow-up 19.15°, concentrical acetabulum 93.7%. All of the fibulat allografts were completely incorporated mean 14 weeks (range, 12 weeks - 17 weeks) post-surgery. There were five (4.7%) redislocation and subluxation, three AVN (2.8%) and five (4.7%) coxa magna Without graft infections, none of the osteotomies required internal fixation for stability. Final results: Excellent 70 (66.0%), Good 29 (27.4%), Fair 2 (1.9%), Poor 5 (4.7%). Conclusion: Open reduction and modified Salter’s innomiate osteotomy allow interposition material by fibular allografting with a short operative incision, renders excellent osteotomy stability that eliminates the need for internal fixation. Surgical technique are safe and effective for Children between twelve and thirty-six months old.展开更多

The age, gender, Gross Motor Function Classification System level, side(s) of operated hip, total time of follow-up, immediate post-operative immobilization, complications, and the need for revision surgery were recorded for all patients. RESULTS: Seventeen patients(81%) were classified as GMFCS level Ⅳ, and 4(19%) patients were classified as GMFCS level Ⅴ. At the time of surgery, the mean age was10.3 years(range: 4-15 years). The mean Reimers' migration percentage improved from 63%(range: 3%-100%) pre-operatively to 6.5%(range: 0%-70%) at the final follow-up(p < 0.05). The mean acetabular angle(AA) improved from 34.1°(range: 19°-50°) pre-operatively to 14.1°(range: 5°-27°)(P < 0.05). Surgical correction of MP and AA was comparable in hips with open(n = 14) or closed(n = 8) triradiate cartilage(P < 0.05). All operated hips were pain-free at the time of the final follow-up visit, although one patient had pain for 6 mo after surgery. We did not observe any cases of bone graft dislodgement or avascular necrosis of the femoral head.CONCLUSION: Pelvic osteotomy through a less invasive surgical approach appears to be a valid alternative with similar outcomes to those of standard techniques. This method allows for less muscle stripping and blood loss and a shorter operating time.展开更多

However, several reports have described potential osteotomy-related complications such as nonunion, tibial tubercle migration and fragmentation, and metalware related pain.AIM To evaluate the literature and estimate the efficiency of TTO in RTKA in terms of osteotomy union, knee mobility and complications.METHODS MEDLINE, Scopus, and the Cochrane Central Register of Controlled Trials were investigated for completed studies until February 2020. The principle outcome of the study was the incidence of union of the osteotomy. Secondary outcomes were the knee range of motion as well as the TTO-related and overall procedure complication rate.RESULTS Fifteen clinical studies with a total of 593 TTOs were included. The TTO union rate was 98.1%. Proximal migration and anterior knee pain were the most common TTO-related complications accounting for 6.9% and 6.4% of all cases,respectively. However, only 2.2% of cases suffering from anterior knee pain needed hardware removal. Knee flexion was improved from 82.9° preoperatively to 100.1° postoperatively and total knee range of motion was increased from 73.4° before surgery to 97° after surgery. Stiffness requiring manipulation under anesthesia was recorded in 4.6% of cases. No major complications were reported.CONCLUSION The current systematic review supports the use of TTO in RTKA, as it is associated with high union rate, significant improvement in knee motion and low osteotomy-related complication risk that rarely leads to secondary tibial tubercle procedures.展开更多

文摘Monteggia fracture-dislocation is a rare and complex injury that typically involves an ulnar fracture combined with a dislocation of the proximal radioulnar and radiocapitellar joints.Ulnar osteotomy is an effective treatment method.This article reports a case of chronic Monteggia fracture in an 11-year-old male patient successfully treated with a simple proximal ulnar osteotomy.
文摘BACKGROUND Accurate surgical fixation of intra-articular distal humerus fractures require olecranon osteotomy.Repair of osteotomy is achieved with a variety of techniques but no consensus has been achieved regarding the optimum technique for fixing the olecranon osteotomy.In this retrospective study,we compared the functional and radiological outcome of the two commonly used techniques of fixing olecranon osteotomy after fixing distal humerus intra-articular fractures.We hypothesized that olecranon osteotomy fixed with 6.5 mm cancellous intramedullary screw alone yielded better radiological and functional outcome than fixation with cerclage wire over cancellous screw applied in figure of eight as tension band wiring(TBW).AIM To determine the radiological and functional outcome of olecranon osteotomy fixation with cancellous screw alone vs cancellous screw combined with cerclage wiring applied as TBW.METHODS This retrospective study was conducted in Lady Reading Hospital Peshawar Pakistan.Intra-articular distal humerus fractures fulfilling the inclusion criteria and operated during 2023 to 2025 were included.Olecranon osteotomy fixation with 6.5 mm cancellous screw alone was labelled as group A while cerclage wire over cancellous screw in figure of eight as TBW were labelled as group B.The demographics,radiological and functional outcome in both groups were compared at one year using Mayo Elbow Performance Score and Quick Disabilities of the Arm,Shoulder,and Hand Score.RESULTS We included 32 patients in this study.The mean age of group A patients was 34±5.5 years while group B had a mean age of 34±6.2 years.Radiological union of olecranon osteotomy was achieved in all cases in both groups.Functional outcome however was significantly better in group A than in group B(P<0.05).The Mayo Elbow Performance Score was excellent in 14(87.5%)and good in 2(12.5%)patients in group A while 7(43.47%)patients had excellent outcome,5(31.25%)good and 4(25%)had fair outcome in group B.The mean Quick Disabilities of the Arm,Shoulder,and Hand Score was 24.5±2.1 and 78.1±12.1 in group A and B respectively(P<0.05).CONCLUSION Similar radiological union was achieved in all patients of olecranon osteotomy treated with intramedullary screw alone and intramedullary screw with TBW.Functional outcome however was significantly better in intramedullary screw alone than in intramedullary screw with TBW.
文摘BACKGROUND The morbidity and burden of knee osteoarthritis affecting millions of lives worldwide has created a constant pursuit in finding the ideal treatment for knee osteoarthritis.There has been a paradigm shift in the surgical treatment of osteoarthritis ever since the initial description of Volkmann’s tibial osteotomy.This review focuses on one such recent procedure,the proximal fibular osteotomy(PFO)for medial compartment knee osteoarthritis.This review encompasses the history,evidence,risk factors,outcomes and technical considerations of PFO.AIM To understand the evidence and its techniques,and whether this could be an alternative solution to the problem of knee osteoarthritis in the developing world.METHODS The phrases“proximal fibular osteotomy”and“knee osteoarthritis”were searched(date of search December 20,2019)on PubMed to identify articles evaluating the biomechanical and clinical outcomes of PFO in patients with knee osteoarthritis.A total of 258 were retrieved.After reviewing the summary of the texts,22 articles written in English were marked for abstract review.Articles that were case studies or cadaver experiments were excluded.The abstracts of the remaining articles were read,and only those that focused on the history,outcomes of case studies and technical considerations of PFO were included in the review.A total of 12 articles were included in this review.RESULTS At least six studies reported improvement in the visual analogue scale(VAS)from the average preoperative VAS score[6.32,95%confidence interval(CI)=(4.05,8.59)]to average postoperative VAS score[1.23,95%CI:(-1.20,3.71)],which was statistically significant.Similarly,the American Knee Society Score(KSS)functional score improved from an average preoperative KSS functional score[43.11,95%CI:(37.83,48.38)]to postoperative KSS functional score[66.145,95%CI:(61.94,70.35)],which was statistically significant.The femorotibial angle improved by around 7º,and the hip knee ankle angle improved by around 6º.CONCLUSION With the existing data,it seems that PFO is a viable option for treating medial joint osteoarthritis in selected patients.Long term outcome studies and progression of disease pathology are some of the important parameters that need to be addressed by use of multicenter randomized controlled trials.

文摘This study was to describe the use of inverted-L osteotomy of ramus and lilac bone graft for the management of mandibular deficiency in adult patients. From 2008 to 2010, 11 patients (aged 19 to 29 years) with mandibular deficiency underwent intraoral or extraoral inverted-L osteotomy of ramus and lilac crest bone grafting. Data were collected from the patients' records, photographs and radiographs. The height and width of the ramus were successfully expanded by inverted-L osteotomy and lilac crest bone grafting with minimal complications in all patients, resulting in significant improvement in occlusion and facial appearance. Our early results showed that the inverted-L osteotomy of ramus and lilac crest bone grafting is safe and effective, and should be considered as a good alternative for the patients with mandibular deficiency.
文摘For young, active patients with healthy hip cartilage, pelvic osteotomy is a surgical option in to address hip pain and to improve mechanical loading conditions related to dysplasia. Hip dysplasia may lead to arthrosis at an early age due to poor coverage of the femoralhead and abnormal loading of the joint articulation. In patients with symptomatic dysplasia and closed triradiate cartilage(generally over age 10), including adolescents and young adults(generally up to around age 40), the Bernese periacetabular osteotomy(PAO) is a durable technique for addressing underlying structural deformity. The PAO involves a modified Smith-Petersen approach. Advantages of the Bernese osteotomy include preservation of the weight-bearing posterior column of the hemi-pelvis, preservation of the acetabular blood supply, maintenance of the hip abductor musculature, and the ability to effect powerful deformity correction about an ideal center of rotation. There is an increasing body of evidence that preservation of the native hip can be improved through pelvic osteotomy. In contrast to hip osteotomy and joint preservation, the role of total hip arthroplasty in young, active patients with correctable hip deformity remains controversial. Moreover, the durability of hip replacement in young patients is inherently limited. Pelvic osteotomy should be considered the preferred method to address correctable structural deformity of the hip in the young, active patient with developmental dysplasia. The Bernese PAO is technically demanding, yet offers reproducible results with good long-term survivorship in carefully selected patients with preserved cartilage and the ability to meet the demands of rehabilitation.
文摘BACKGROUND High tibial osteotomy(HTO)is a well-established method for the treatment of medial compartment osteoarthritis of the knee with varus deformity.However,HTO alone cannot adequately repair the arthritic joint,necessitating cartilage regeneration therapy.Cartilage regeneration procedures with concomitant HTO are used to improve the clinical outcome in patients with varus deformity.AIM To evaluate cartilage regeneration after implantation of allogenic human umbilical cord blood-derived mesenchymal stem cells(hUCB-MSCs)with concomitant HTO.METHODS Data for patients who underwent implantation of hUCB-MSCs with concomitant HTO were evaluated.The patients included in this study were over 40 years old,had a varus deformity of more than 5°,and a full-thickness International Cartilage Repair Society(ICRS)grade IV articular cartilage lesion of more than 4 cm2 in the medial compartment of the knee.All patients underwent second-look arthroscopy during hardware removal.Cartilage regeneration was evaluated macroscopically using the ICRS grading system in second-look arthroscopy.We also assessed the effects of patient characteristics,such as trochlear lesions,age,and lesion size,using patient medical records.RESULTS A total of 125 patients were included in the study,with an average age of 58.3±6.8 years(range:43-74 years old);95(76%)were female and 30(24%)were male.The average hip-knee-ankle(HKA)angle for measuring varus deformity was 7.6°±2.4°(range:5.0-14.2°).In second-look arthroscopy,the status of medial femoral condyle(MFC)cartilage was as follows:73(58.4%)patients with ICRS grade I,37(29.6%)with ICRS grade II,and 15(12%)with ICRS grade III.No patients were staged with ICRS grade IV.Additionally,the scores[except International Knee Documentation Committee(IKDC)at 1 year]of the ICRS grade I group improved more significantly than those of the ICRS grade II and III groups.CONCLUSION Implantation of hUCB-MSCs with concomitant HTO is an effective treatment for patients with medial compartment osteoarthritis and varus deformity.Regeneration of cartilage improves the clinical outcomes for the patients.
文摘A wide variety of pelvic osteotomies have been developed for the treatment of developmental dysplasia of the hip(DDH). In the present paper, we present a detailed review of previous studies of triple osteotomy as an alternative treatment for DDH. We also report our experience treating 6 adult cases of DDH by triple osteotomy in order to highlight the various aspects of this procedure.The mean age of our patients was 31.2 years with a mean follow-up period of 6 years. We assessed range of motion, center-edge angle, acetabular index angle, Sharp angle, acetabulum head index, head lateralization index, Japanese Orthopedic Association score, Harris hip score, patient satisfaction, and the difference between lower limb lengths before and after the procedure. At final follow-up, clinical scores were significantly improved and radiographic parameters also showed good correction of acetabulum.
文摘Nonunion neck of femur can be a difficult problem to treat, particularly in the young, and is associated with high complication rates of avascular necrosis due to the precarious blood supply and poor biomechanics.The various treatment options that have been described can be broadly divided according to the aim of improving either biology or biomechanics. Surgeries aimed at improving the biology, such as vascularized fibula grafting, have good success rates but require high levels of expertise and substantial resources. A popular surgical treatment aimed at improving the biomechanics-valgus intertrochanteric osteotomyoptimizes conditions for fracture healing by converting shear forces across the fracture site into compressive forces. Numerous variations of this surgical procedure have been developed and successfully applied in clinical practice. As a result, the proximal femoral orientation for obtaining a good functional outcome has evolved over the years, and the present concept of altering the proximal femoral anatomy as little as possible has arisen. This technical objective supports attaining union as well as a good functional outcome, since excessive valgus can lead to increased joint reaction forces. This review summarizes the historical and current literature on valgus intertrochanteric osteotomy treatment of nonunion neck of femur, with a focus on factors predictive of good functional outcome and potential pitfalls to be avoided as well as controversies surrounding this procedure.

文摘Summary: Preoperative planning of corrective osteotomy with traditional radiography has limitations in regards to determining the ideal osteotomy location and orientation in three-dimensional femoral de- formities. Though a successful operation can be planned preoperatively, intraoperative contingencies might adhere to the procedural plan in the performance of operation. To efficiently perform a planned procedure, proposed is a design to implement three-dimensional reconstruction photography, based on computer-tomography (CT) scan. A custom-made guide was designed to navigate the osteotomy as planned, and additionally, a personalized intramedullary nail was used for fixation after osteotomy. Three-dimensional (3D) photography of deformed femur was established based on the CT dataset and transferred into 3D photography processing software for further planning. Osteotomy planes were de- signed and adjusted at deformity sites to correct the 3D deformities. The methodology of a custom-made osteotomy guide was introduced in femoral corrective osteotomy, for the first time, to navigate the op- eration as planned. After the virtual osteotomy and reduction of bone segments, the parameters of a custom-made intramedullary nail were measured for manufacturing. Findings Virtual operation in computer shows complete correction of the 3D deformity. The osteotomy guide, obtained by rapid-prototyping techniques, navigates mimicking surgery on rapid-prototyping model of the involved femur as planned. Internal fixation was achieved using the custom-made intramedullary nail. Interpreta- tion three-dimensional visualization introduces an advantage in preoperative planning for corrective os- teotomy of 3D femoral deformity, and the custom-made osteotomy guide is crucial to realize such a de- liberate plan during the actual procedures. The internal fixator, such as an intramedullary nail, can be modified or personalized for fixation in unique cases.
文摘BACKGROUND Cavovarus foot is a common form of foot deformity in children,which is clinically characterized by an abnormal increase of the longitudinal arch of the foot,and it can be simultaneously complicated with forefoot pronation and varus,rearfoot varus,Achilles tendon contracture,or cock-up toe deformity.Muscle force imbalance is the primary cause of such deformity.Many diseases can lead to muscle force imbalance,such as tethered cord syndrome,cerebral palsy,Charcot-Marie-Tooth disease,and trauma.At present,many surgical treatments are available for cavovarus foot.For older children,priority should be given to midfoot osteotomy and fusion.Since complications such as abnormal foot length,foot stiffness,and abnormal gait tend to develop postoperatively,it is important to preserve the joints and correct the deformity as much as possible.Adequate soft tissue release and muscle balance are the keys to correcting the deformity and avoiding its postoperative recurrence.AIM To assess the efficacy of soft tissue release combined with joint-sparing osteotomy in the treatment of cavovarus foot deformity in older children.METHODS The clinical data of 21 older children with cavovarus foot deformity(28 feet)who were treated surgically at the Ninth Department of Orthopedics of Jizhong Energy Xingtai Mining Group General Hospital from November 2014 to July 2017 were retrospectively analyzed.The patients ranged in age from 10 to 14 years old,with an average age of 12.46±1.20 years.Their main clinical manifestations were deformity,pain,and gait abnormality.The patients underwent magnetic resonance imaging of the lumbar spine,electromyographic examination,weightbearing anteroposterior and lateral X-rays of the feet,and the Coleman block test.Surgical procedures including metatarsal fascia release,Achilles tendon or medial gastrocnemius lengthening,"V"-shaped osteotomy on the dorsal side of the metatarsal base,opening medial cuneiform wedge osteotomy,closing cuboid osteotomy,anterior transfer of the posterior tibial tendon,peroneus longus-tobrevis transfer,and calcaneal sliding osteotomy to correct hindfoot varus deformity were performed.After surgery,long leg plaster casts were applied,the plaster casts were removed 6 wk later,Kirschner wires were removed,and functional exercise was initiated.The patients began weight-bearing walk 3 mo after surgery.Therapeutic effects were evaluated using the Wicart grading system,and Meary’s angles and Hibbs’angles were measured based on X-ray images obtained preoperatively and at last follow-up to assess their changes.RESULTS The patients were followed for 6 to 32 mo,with an average follow-up period of 17.68±6.290 mo.Bone healing at the osteotomy site was achieved at 3 mo in all cases.According to the Wicart grading system,very good results were achieved in 18 feet,good in 7,and fair in 3,with a very good/good rate of 89.3%.At last follow-up,mean Meary’s angle was 6.36°±1.810°,and mean Hibbs’angle was 160.21°±4.167°,both of which were significantly improved compared with preoperative values(24.11°±2.948°and 135.86°±5.345°,respectively;P<0.001 for both).No complications such as infection,skin necrosis,or bone nonunion occurred.CONCLUSION Soft tissue release combined with joint-sparing osteotomy has appreciated efficacy in the treatment of cavovarus foot deformity in older children.
文摘Restoration of fracture alignment by osteotomy is crucial for the management of humeral nonunion. In the present study, we introduced a new way of osteotomy (Z-shaped) in treating humeral shaft nonunion secondary to failed plate osteosynthesis. Clinical data of 24 patients with humeral shaft nonunion following implant failure (from 2010 to 2014) were retrospectively evaluated. These patients underwent Z-shaped osteotomy in revision surgery after the initial surgery, plate osteosynthesis, was failed. Outcomes were evaluated using visual analogue scale (VAS) and Constant and Murley score. Repeated analysis of variance (ANOVA) was used for statistical analysis. Patients were followed up for a minimum of 24 months (26.83±4.33 months). The operative time was 102.33±10.16 min, and hospital stay averaged 9.75±2.13 days. All patients achieved clinical union at the latest follow-up. Complications included radial palsy (n=1) and superficial wound infection (n=1). The postoperative VAS scores decreased significantly compared to preoperative score (F=257.99, P<0.01). Constant and Murley score increased and reached 81.33±0.95 at 24 months' follow-up 0=247.35, P<0.01). Among all the cases, 15 cases were graded as "excellent", and 9 as "good". In conclusion, Z-shaped osteotomy was easy to perform, and it provided additional medial support with more bone contact areas. Revision surgery using locking plate and Z-shaped osteotomy achieved high union rate and improved functional outcome. It was a reasonable and safe option for treating humeral nonunion following implant failure.
文摘Consistent with an aging population, the overall number of distal humeral fractures in the elderly is increasing. Indications for application of acute total elbow arthroplasty (TEA) in the setting of distal humeral fractures are still being defined. A variety of factors including chronologic age, physiologic age, bone quality, presence of pre-existing arthritis and pre-existing medical conditions need to be considered. Optimally the decision to proceed with TEA verses open reduction internal fixation (ORIF) is made preoperatively. The need to abandon ORIF may be not be apparent until after fracture exposure, and the presence of an olecranon osteotomy makes performing TEA challenging. A case is presented of acute conversion from ORIF to TEA following olecranon osteotomy, utilizing internal fixation bridging the ulnar component and its cement mantle.
文摘In addressing spinal sagittal imbalance through a posterior approach, the surgeon now may choose from among a variety of osteotomy techniques. Posterior column osteotomies such as the facetectomy or Ponte or Smith-Petersen osteotomy provide the least correction, but can be used at multiple levels with minimal blood loss and a lower operative risk. Pedicle subtraction osteotomies provide nearly 3 times the per-level correction of Ponte/Smith-Petersen osteotomies; however, they carry increased technical demands, longer operative time, and greater blood loss and associated significant morbidity, including neurological injury. The literature focusing on pedicle subtraction osteotomy for fixed sagittal imbalance patients is reviewed. The longterm overall outcomes, surgical tips to reduce the complications and suggestions for their proper application are also provided.

文摘Objective: To introduce and characterize the modified biplanar opening high tibial osteotomy with rigid fixation to treat varus knee in young and active patients. Methods: Between June 2001 to July 2008, 18 patients with monocompartmental degeneration of the knee combined with a varus malalignment of the leg had the modified biplanar opening high tibial osteotomy and the osteotomy was fixed with the locking plates (Locking Compression Plate System). The mean varus deformity before operation was 11.5° (5°- 19°) and no degenerative changes were found in other departments. Stability of the knee was normal in 15 patients, but ruptures in anterior cruciate ligaments or lateral collateral ligament were presented in the remaining 3 patients. Preoperative symptom was mainly limited in the pain of medial compartment. The preoperative and follow-up data for the range of motion and Lysholm score were determined. Subjective satisfactory examination was also applied to the patients for the operation they selected. Results: All of the patients were followed up with an average of 32.5 months (12-82 months). There was no ununion or delayed union in this group during the follow-up period. No complications like broken plate, nerve injury, or blood vessel injury occurred. The postoperative average corrected degree was 9.5° (5.5°-18°). No degenerations developed in the three departments of the knee. The Lysholm scores before and after surgery were 42.5 and 77.5, respectively (P〈0.01). The overall fineness rate was 83.3%. The subjective satisfactory survey demonstrated that about 83.3% patients showed satisfactory on the operation. There was no obvious difference in the range of motion before and after operation, but significant changes were found in the Lysholm score and varus degree from preoperative to follow-up. Conclusion: Proximal opening high tibial osteotomy performed in conjunction with the special rigid locking plate yielded good results for symptomatic genu varum. This new classic technique can be effectively applied to the medial compartment degeneration of the knee in active young patients.
文摘Background: Innominate osteotomy procedures have been widely used as an integral component of combined surgery to treat developmental dysplasia of the hip in children. Autograft concern is further supported by authors who suggest the routine use of internal fixation. Problems such as graft extrusion, rotation and absorption, leading to loss of acetabular correction, were often noted in cases previously treated at our National Hospital for Pediatrics. This retrospective study reviewed the radiographic results of this treatment protocol in 106 hips developmental dislocated hips which met our inclusion criteria. The efficacy of this method to achieve and maintain a well covered and stable hip was the main objective of the study. Methods: This retrospective study reviewed the radiographs of 106 hips presenting with developmental dislocation which were treated by modified Salter’s innomiate osteotomy and using a fibular allograft as the interposition material. Dislocations of the hip were graded using the T?nnis system. Measurement of the acetabular index (AI) was the main variable. The minimum follow up period was 2 years. Possible complications such as loss of acetabular correction, hip redislocation, graft extrusion or resorption, the need for osteotomy internal fixation, delayed or non union, infection or avascular necrosis (AVN) were documented in this series. Results: Between January 2004 and December 2008, 106 surgeries were performed in 95 patients. Sixty-three (86.3%) of the patients were girls and ten (13.7%) were boys, thirteen patients (13.7%) were between twelve and eighteen months old at the time of the operation, the remaining eighty-two (86.3%) patients being between eighteen and thirty-six months old, with the mean age of 22.6 months at the time of surgery. There were eleven (11.6%) patients who had bilateral dislocation. Eighty-four (88.4%) patients were affected unilaterally. The right hip was involved in seventeen (17.9%) and the left hip in sixty-seven (70.5%) cases. T?nnis system Type 3 was in 34 hip (32.1%), and Type 4 was in 72 hip (67.9%). All patients combined open reduction and modified Salter’s innomiate osteotomy, inserting a fibular allograft as the interposition material. Acetabular index was improved, preoperation was 42.95°, and latest follow-up 19.15°, concentrical acetabulum 93.7%. All of the fibulat allografts were completely incorporated mean 14 weeks (range, 12 weeks - 17 weeks) post-surgery. There were five (4.7%) redislocation and subluxation, three AVN (2.8%) and five (4.7%) coxa magna Without graft infections, none of the osteotomies required internal fixation for stability. Final results: Excellent 70 (66.0%), Good 29 (27.4%), Fair 2 (1.9%), Poor 5 (4.7%). Conclusion: Open reduction and modified Salter’s innomiate osteotomy allow interposition material by fibular allografting with a short operative incision, renders excellent osteotomy stability that eliminates the need for internal fixation. Surgical technique are safe and effective for Children between twelve and thirty-six months old.
文摘AIM: To describe the surgical technique of and indications for percutaneous pelvic osteotomy in patients with severe cerebral palsy.METHODS: Twenty-one non-ambulatory children and adolescents(22 hips) were consecutively treated with percutaneous pelvic osteotomy, which was used in conjunction with varus, derotational, shortening femoral osteotomy and soft tissue release, to correct progressive hip subluxation and acetabular dysplasia. The age, gender, Gross Motor Function Classification System level, side(s) of operated hip, total time of follow-up, immediate post-operative immobilization, complications, and the need for revision surgery were recorded for all patients. RESULTS: Seventeen patients(81%) were classified as GMFCS level Ⅳ, and 4(19%) patients were classified as GMFCS level Ⅴ. At the time of surgery, the mean age was10.3 years(range: 4-15 years). The mean Reimers' migration percentage improved from 63%(range: 3%-100%) pre-operatively to 6.5%(range: 0%-70%) at the final follow-up(p < 0.05). The mean acetabular angle(AA) improved from 34.1°(range: 19°-50°) pre-operatively to 14.1°(range: 5°-27°)(P < 0.05). Surgical correction of MP and AA was comparable in hips with open(n = 14) or closed(n = 8) triradiate cartilage(P < 0.05). All operated hips were pain-free at the time of the final follow-up visit, although one patient had pain for 6 mo after surgery. We did not observe any cases of bone graft dislodgement or avascular necrosis of the femoral head.CONCLUSION: Pelvic osteotomy through a less invasive surgical approach appears to be a valid alternative with similar outcomes to those of standard techniques. This method allows for less muscle stripping and blood loss and a shorter operating time.

文摘Patient-specific instrumentation(PSI)enables a more accurate alignment of the lower limbs in a high tibial osteotomy(HTO)than in traditional surgery;however,the current design of commercial PSIs is not perfect.Therefore,we designed a new patient-specific surgical guide to improve the accuracy of the osteotomy and verified its reliability through a clinical operation.Here,we describe a patient with isolated medial-compartment bilateral knee osteoarthritis,accompanied by a varus deformity of the proximal tibia.The patient was treated with HTO using a patient-specific 3D-printed surgical guide.We concluded that the patient-specific 3D-printed surgical guide improved the accuracy of the osteotomy and the alignment of the lower limb.
文摘BACKGROUND Tibial tubercle osteotomy(TTO) is a well-established surgical technique to deal with a stiff knee in revision total knee arthroplasty(RTKA). However, several reports have described potential osteotomy-related complications such as nonunion, tibial tubercle migration and fragmentation, and metalware related pain.AIM To evaluate the literature and estimate the efficiency of TTO in RTKA in terms of osteotomy union, knee mobility and complications.METHODS MEDLINE, Scopus, and the Cochrane Central Register of Controlled Trials were investigated for completed studies until February 2020. The principle outcome of the study was the incidence of union of the osteotomy. Secondary outcomes were the knee range of motion as well as the TTO-related and overall procedure complication rate.RESULTS Fifteen clinical studies with a total of 593 TTOs were included. The TTO union rate was 98.1%. Proximal migration and anterior knee pain were the most common TTO-related complications accounting for 6.9% and 6.4% of all cases,respectively. However, only 2.2% of cases suffering from anterior knee pain needed hardware removal. Knee flexion was improved from 82.9° preoperatively to 100.1° postoperatively and total knee range of motion was increased from 73.4° before surgery to 97° after surgery. Stiffness requiring manipulation under anesthesia was recorded in 4.6% of cases. No major complications were reported.CONCLUSION The current systematic review supports the use of TTO in RTKA, as it is associated with high union rate, significant improvement in knee motion and low osteotomy-related complication risk that rarely leads to secondary tibial tubercle procedures.
文摘BACKGROUND High tibial osteotomy(HTO)is a well-known procedure for the correction of knee varus.The purpose of this study was to compare the radiological results and accuracy of deformity correction performed using two different techniques:acute opening wedge correction using a plate and gradual correction with a monolateral external fixator.AIM To compare of the radiological results of two different techniques:acute opening wedge correction(a plate and screw)and gradual correction(external fixator).METHODS A total of 43 patients with plates and 36 patients with external fixators were included.All patients had moderate uniplanar varus deformities.We measured radiographic parameters,including the mechanical axis deviation(MAD),medial proximal tibial angle(MPTA),Caton-Deschamps Index(CDI),posterior proximal tibial angle,and joint line obliquity angle(JLOA).The accuracy of MAD correction was calculated based on a correction goal of neutral or overcorrection for medial compartment arthritis.RESULTS Demographics including age,body mass index,sex,and preoperative deformities were similar between the groups.The MAD significantly improved from 23.6 mm medial to the midline(SD=8.2 mm)to 6.9 mm lateral to the midline(SD=5.4 mm)(P<0.001).The accuracy of MAD correction did not differ between the groups and was 96.1%(SD=8.1%)in the plate group and 98.2%(SD=5.2%)in the external fixator group(P=0.18).The MPTA significantly improved from 83.9°(SD=2.9°)to 90.9°(SD=3.3°)(P<0.001),and the change was similar between the groups.Differences were noted in patella height,with a CDI change of-19.2%(SD=13.7%)and 3.1%(SD=8.0%)for the plate and external fixator groups,respectively(P<0.001).The change in JLOA was 1.6 degrees(SD=1.1 degrees)and 0.9 degrees(SD=0.9 degrees)for the plate and external fixator groups,respectively(P=0.04).CONCLUSION Reliable correction of moderate varus alignment was achieved with both the acute opening wedge technique with a plate and the gradual monolateral external fixator technique.The patellar height decreased with the open wedge plate technique.Joint line obliquity decreased to a greater degree with the open wedge plate technique,perhaps as a result of medial collateral ligament release.The appropriate technique should be selected based on surgeon and patient preferences;however,external fixation may be a better choice when the preservation of patellar height is deemed important.
