The diversity of fracture patterns encountered renders objective classification of prognostic value challenging. Non-operative management has been associated with good functional outcomes in stable, minimally displaced and certain types of displaced fractures.Absolute indications for surgery are infrequent and comprise compound, pathological, multi-fragmentary head-splitting fractures and fracture dislocations, as well as those associated with neurovascular injury. A constantly expanding range of reconstructive and replacement options however has been extending the indications for surgical management of complex proximal humerus fractures. As a result, management decisions are becoming increasingly complicated, in an attempt to provide the best possible treatment for each indi-vidual patient, that will successfully address their specific fracture configuration, comorbidities and functional expectations. Our aim was to review the management options available for the full range of proximal humerus fractures in adults, along with their specific advantages, disadvantages and outcomes.展开更多

With better understanding of the anatomy and imaging advancements, the complex nature of these fractures is well appreciated now. These fractures involve metaphysealcomminution of lateral column and associated intraarticular injuries are common. Previously, closed reduction and excision were the accepted treatment but now preference is for open reduction and internal fixation with an aim to provide stable and congruent joint with early range of motion of joint. Various approaches including extensile lateral, anterolateral and posterior approaches have been described depending on the fracture pattern and complexity. Good to excellent outcome have been reported with internal fixations and poor results are noted in articular comminution with associated articular injuries. Various implants including headleass compression screws, minifragment screws, bioabsorbable implants and column plating are advocated for reconstruction of these complex fractures. Inspite of articular fragments being free of soft tissue attachments the rate of osteonecrosis and osteoarthritis is reported very less after internal fixation. This article summarizes the diagnostic and treatment strategies for these rare fractures and recommendations for management.展开更多

Methods: Humerus pattern was established based on the CT images, and calculation was done by ANSYS5. 6 software. Three dimensional ten-node tetrahedron unit was selected and were divided into 2 729 nodes, 49 041 units. Distribution and amount of axial compression of humerus were analyzed when clip angle was 30°, 45°, 90° between fracture face and axial line with fixed X, Y, Z directions. Results: The distribution of stress was greatly different between fracture face and non fracture face. Stress in fracture part was fairly concentrated with incomplete symmetric distribution around the center of fracture face; Greater stress distributed in the regions 10 mm from fracture face, which was 2-3 times that of other stress regions. Conclusion: Required load must be estimated under various conditions as to select the suitable internal fixation implants during the treatment of humerus fracture, which can provide helpful stress environment for fracture healing.展开更多

Case reports of isolated lesser tuberosity fractures are particularly rare and, consequently,therapeutic protocols have not yet been completely clarified. Conservative as well as surgical treatment has been recommended, while several operative techniques have been applied. We present a case of a 39-yearold man with an isolated lesser tuberosity fracture who was treated surgically in our institution. Due to fracture comminution, a two-level reconstruction technique with headless screws and buttress plate was applied. As far as we know, this method of fixation of this type of fracture has not been previously described in the literature.The patient tolerated the procedure well and excellent results were obtained at the latest follow-up.展开更多

In a prospective randomized study we included a consecutive series of 40 patients with a proximal humeral fracture in this study. All fractures were stabilized surgically with a fixed-angle “Philos plate” from May 2008 through May 2009. All patients were divided in two groups: Group I with plate osteosynthesis without TachoSil, Group II with plate osteosynthesis with TachoSil. For statistical analysis Chi2- Test and U- Test were used. There were 4 perioperative complica- tions in group II and one complication in group I (Chi2-Test: p=0.233). In group II one hardware failure occurred due to osteoporosis requiring revision and reosteosynthesis. Another patient suffered from paralysis of the radial nerve which healed uneventfully. One superficial postopera-tive infection and one superficial hematoma re-quired revision surgery, too. In this group no subfascial hematoma developed. One subfascial hematoma which required no revision occurred in group I. Blood transfusion was required 2 times in group I and 3 times in group II (Chi2-Test: p = 0.549). In sum in group II there was a sig-nificant lower blood loss for the subfascial drain, the region where TachoSil was applied. No ad-verse affects related to TachoSil could be de-tected. TachoSil was found to be safe and effective for reduction of postoperative bleeding following operative treatment of proximal hume-rus fractures. Further studies with larger sample size are required to confirm the efficacy of TachoSil? in orthopedic surgery.展开更多

Operative management includes closed reduction and placement of 2 to 3 laterally based pins. Occasionally, a medial pin is used to create a crossed fixation pattern, despite risk of nearly 10% iatrogenic ulnar nerve injury. The objective of this study was to assess the trends and outcomes in the operative management of pediatric supracondylar humerus fractures at a level one academic trauma center. Materials & Methods: A retrospective review was performed on all children sustaining a Gartland type II or III supracondylar humerus fractures treated by closed or open reduction and percutaneous pinning in 2006-2008 and 2009-2011 at a level one academic trauma center by two of the authors (JTR, LMT). Pin placement patterns were evaluated and compared based on year performed. Outcomes measured were rates of ulnar nerve symptoms, non-union, re-operation, and varus malalignment. Data analysis was performed using a Fisher exact test on STATA software. Results: A total of 49 patients met inclusion criteria. Of 22 patients treated in 2006-2008, 5 (23%) were type II and 17 (77%) were type III. From 2009-2011, 16 (59%) were type II and 11 (41%) were type III. Comparison of pinning pattern in type II fractures between 2006-2008 and 2009-2011 did not indicate statistical significance (p = 0.429). Comparison of pinning pattern in type III fractures during the same time period did show that there was a statistically significant decrease (p = 0.010) in the number of cross pin fixations. There were no ulnar nerve injuries, non-unions, re-operations, or varus malalignment in any patient on final follow-up. Conclusion: This study shows that there has been a significant decrease in cross pin fixation for pediatric type III supracondylar humerus fractures with equivalent clinical outcomes at a Level I trauma center. Furthermore, performing lateral pinning for type III fractures has eliminated the risk of iatrogenic ulnar nerve injury. Level of Evidence: Level III—Retrospective cohort study.展开更多

Traditionally the distal locking of intramedullary humeral nails is achieved using a freehand technique. The humerus nailing locking options in the conventional nailing systems are placed in the anterior-posterior and lateral-medial directions. It exposes both the patient and surgeon to radiation, is time consuming, and has a potential risk of damaging neurovascular structures, especially the radial and lateral cutaneous nerve when the anterior-posterior and lateral-medial locking constructs are used. We aim to present a technical tip to ease the distal locking procedure and avoid the possible neurovascular complications with the existing nailing systems.展开更多

文摘BACKGROUND Fracture nonunion represents a challenging complication during fracture repair,often necessitating surgical intervention.Teriparatide,a recombinant human parathyroid hormone,has demonstrated promise in enhancing fracture healing,although its efficacy in treating established nonunion remains under investigation.CASE SUMMARY We report a case of a 27-year-old male who presented with a right humerus fracture following a traffic accident.Despite undergoing open reduction and internal fixation,the fracture resulted in a delayed union and subsequent nonunion.After 4 years of conservative management,teriparatide treatment was initiated due to persistent nonunion.Teriparatide injections were administered daily for 6 months,resulting in complete fracture healing and resolution of pain.CONCLUSION Our case demonstrates the successful use of teriparatide in treating a prolonged nonunion of a humerus fracture.Teriparatide may provide a valuable therapeutic option for established bone nonunion,even in cases that have not responded to conservative treatments.
文摘BACKGROUND Supracondylar humeral fractures(SCHF)are the second most common fractures in childhood and can lead to short-and long-term complications.Despite their prevalence,the anatomical factors that predispose children to SCHF remain unclear.This study aimed to determine whether there are significant morpho-logical differences in the elbow by comparing the radiographic angular measure-ments of the contralateral elbows of patients with SCHF to those of patients with distal radius fractures(DRF)and a healthy control group.We sought to explore if these morphological variations contribute to the occurrence of SCHF.Radiographs of 78 SCHF patients were analyzed for angular measurements of the contralateral elbow.Two control groups were used:98 healthy children and 40 patients with DRF.Angular measurements included Baumann angle(BA),hu-meroulnar angle(HUA),humerus metaphysis-diaphysis angle(HMDA),humerus shaft-condylar angle(HSCA),and lateral capitellohumeral angle.Only BA,HUA,and HMDA were measured in the DRF group.Statistical analysis was performed to compare differences among groups.RESULTS Significant differences were found in elbow measurements between SCHF and control groups(P<0.05).However,the mean values for all groups fell within the ranges described in the literature.CONCLUSION While statistically significant differences were found in elbow morphology between SCHF patients and controls,these differences don't translate into clinically meaningful morphological deviations.
文摘BACKGROUND Simple bone cysts(SBC)are benign tumor-like bone lesions typically identified in children.While SBC may lead to growth disturbances or growth arrest,such cases are uncommon.The mechanisms behind these observations remain unclear.Additionally,research on the etiology of SBC remains inconclusive,and there has been no consensus on the appropriate timing and methodology for treatment.CASE SUMMARY Here,we present our experience in the successful surgical management of a 10-year-old girl with SBC,who presented with a pathological fracture complicated by malunion of the displaced fracture,varus deformity,and limb length discrepancy.We hypothesized two possible etiologies for the patient’s growth arrest and subsequent humerus varus deformity:(1)Direct disruption of the physis by fluid from the cyst itself;and(2)damage to the epiphysis due to repetitive pathological fractures associated with SBC.In addressing this case,surgical intervention was undertaken to correct the proximal humerus varus deformity.This approach offered the advantages of simultaneously correcting angular abnormalities,achieving mild limb lengthening,providing definitive SBC treatment,and reducing the overall treatment duration.CONCLUSION As per current literature,acute correction of acute angular deformity in proximal humeral SBC is not well comprehended.However,in this specific case,acute correction was considered an optimal solution.
文摘BACKGROUND Distal humerus elbow fractures are one of the most common traumatic fractures seen in pediatric patients and present as three main types:Supracondylar(SC),lateral condyle(LC),and medial epicondyle(ME)fractures.AIM To evaluate the epidemiology of pediatric distal humerus fractures(SC,LC,and ME)from an American insurance claims database.METHODS A retrospective review was performed on patients 17 years and younger with the ICD 9 and 10 codes for SC,LC and ME fractures based on the IBM Truven MarketScan®Commercial and IBM Truven MarketScan Medicare Supplemental databases.Patients from 2015 to 2020 were queried for treatments,patient age,sex,length of hospitalization,and comorbidities.RESULTS A total of 1133 SC,154 LC,and 124 ME fractures were identified.SC fractures had the highest percentage of operation at 83%,followed by LC(78%)and ME fractures(41%).Male patients were,on average,older than female patients for both SC and ME fractures.CONCLUSION In the insurance claims databases used,SC fractures were the most reported,followed by LC fractures,and finally ME fractures.Age was identified to be a factor for how a pediatric distal humerus fractures,with patients with SC and LC fractures being younger than those with ME fractures.The peak age per injury per sex was similar to reported historic central tendencies,despite reported trends for younger physiologic development.
文摘The majority of proximal humerus fractures are lowenergy osteoporotic injuries in the elderly and their incidence is increasing in the light of an ageing population. The diversity of fracture patterns encountered renders objective classification of prognostic value challenging. Non-operative management has been associated with good functional outcomes in stable, minimally displaced and certain types of displaced fractures.Absolute indications for surgery are infrequent and comprise compound, pathological, multi-fragmentary head-splitting fractures and fracture dislocations, as well as those associated with neurovascular injury. A constantly expanding range of reconstructive and replacement options however has been extending the indications for surgical management of complex proximal humerus fractures. As a result, management decisions are becoming increasingly complicated, in an attempt to provide the best possible treatment for each indi-vidual patient, that will successfully address their specific fracture configuration, comorbidities and functional expectations. Our aim was to review the management options available for the full range of proximal humerus fractures in adults, along with their specific advantages, disadvantages and outcomes.
文摘Coronal shear fractures of distal humerus involving the capitellum and the trochlea are rare injuries with articular complexity, and are technically challenging for management. With better understanding of the anatomy and imaging advancements, the complex nature of these fractures is well appreciated now. These fractures involve metaphysealcomminution of lateral column and associated intraarticular injuries are common. Previously, closed reduction and excision were the accepted treatment but now preference is for open reduction and internal fixation with an aim to provide stable and congruent joint with early range of motion of joint. Various approaches including extensile lateral, anterolateral and posterior approaches have been described depending on the fracture pattern and complexity. Good to excellent outcome have been reported with internal fixations and poor results are noted in articular comminution with associated articular injuries. Various implants including headleass compression screws, minifragment screws, bioabsorbable implants and column plating are advocated for reconstruction of these complex fractures. Inspite of articular fragments being free of soft tissue attachments the rate of osteonecrosis and osteoarthritis is reported very less after internal fixation. This article summarizes the diagnostic and treatment strategies for these rare fractures and recommendations for management.
文摘Objective: To treat humerus fracture with three dimensional pattern and finite element analysis, providing mechanical basis for treating humerus fracture. Methods: Humerus pattern was established based on the CT images, and calculation was done by ANSYS5. 6 software. Three dimensional ten-node tetrahedron unit was selected and were divided into 2 729 nodes, 49 041 units. Distribution and amount of axial compression of humerus were analyzed when clip angle was 30°, 45°, 90° between fracture face and axial line with fixed X, Y, Z directions. Results: The distribution of stress was greatly different between fracture face and non fracture face. Stress in fracture part was fairly concentrated with incomplete symmetric distribution around the center of fracture face; Greater stress distributed in the regions 10 mm from fracture face, which was 2-3 times that of other stress regions. Conclusion: Required load must be estimated under various conditions as to select the suitable internal fixation implants during the treatment of humerus fracture, which can provide helpful stress environment for fracture healing.
文摘Hepatocellular carcinoma (HCC) is the fish most common cancer in the world. This case documents an unusual metastatic presentation of HCC in the humerus. Preoperative palliative arterial embolization of the tumor was performed to arrest severe tumor bleeding caused by the biopsy. Embolization turned out to be useful also in limiting/preventing potential uncontrolled bleeding during subsequent amputation.
文摘Fractures of the lesser tuberosity of the humerus are typically met in combination with other injuries of the shoulder. Case reports of isolated lesser tuberosity fractures are particularly rare and, consequently,therapeutic protocols have not yet been completely clarified. Conservative as well as surgical treatment has been recommended, while several operative techniques have been applied. We present a case of a 39-yearold man with an isolated lesser tuberosity fracture who was treated surgically in our institution. Due to fracture comminution, a two-level reconstruction technique with headless screws and buttress plate was applied. As far as we know, this method of fixation of this type of fracture has not been previously described in the literature.The patient tolerated the procedure well and excellent results were obtained at the latest follow-up.

文摘BACKGROUND Coronal shear fractures of the distal humerus are rare injuries and are technically challenging to manage.Open reduction and internal fixation(ORIF)has become the preferred treatment because it provides anatomical reduction,stable internal fixation,and early motion,but the optimal surgical approach remains controversial.CASE SUMMARY We report three cases of coronal shear fractures of the distal humerus treated successfully by ORIF via a novel surgical approach,in which lateral epicondyle osteotomy was performed based on the extended lateral approach.We named the novel surgical approach the lateral epicondyle osteotomy approach.All patients underwent surgical treatment and were discharged successfully.All patients had excellent functional results according to the Mayo elbow performance score.The average range of motion was 118°in flexion/extension and 172°in pronation/supination.Only case 2 had a complication,which was implant prolapse.CONCLUSION We demonstrated that the lateral epicondyle osteotomy approach in ORIF is effective and safe for coronal shear fractures of the distal humerus.
文摘To observe the effects of closed reduction and percutaneous K wires fixation of displacd supracondylar humerus fracture in children MethodsRetrospective review of fourteen patients who sustained displaced supracondylar fracture of distal humerus treated by closed reduction and percutaneous K wires fixation Results. All patients’ K wires were removed at 4 weeks post operation Their elbow function regained at 8 weeks The average period of followed up was 10 month (varies from 6 to 18 month), all fractures healed very well without any permanent complications Two transient nerves palsy,ulnar and radial nerve each, recovered completely at 12 weeks and 16 weeks post operation respectively Conclusion. Closed reduction and percutaneous K wires fixation is a safe and efficient treatment for displaced humerus surpracondylar fracture in children
文摘BACKGROUND Humeral shaft fractures are relatively common in adults.Rotational malalignment is reported as one complication but severe rotational deformity of the humerus is extremely rare.To our knowledge,only three cases of symptomatic humeral malrotation have been reported.There are sparse literature reports of humeral reconstruction correction.CASE SUMMARY We present a case of extreme rotational deformity of the humerus(180°)after humeral shaft fracture.The patient complained of pain and difficulties with activities of daily living.In addition,she found the deformity cosmetically unacceptable.Therefore,she was searching for surgical correction.Neurolysis of the radial nerve followed by derotational osteotomy of the humerus and internal fixation were performed.Postoperatively,the patient demonstrated transient iatrogenic radial nerve palsy which recovered completely during postoperative follow-up.The Disabilities of the Arm,Shoulder,and Hand score improved from 55 preoperatively to 16 at the final 2-year follow-up.CONCLUSION Single-stage radial neurolysis,derotational osteotomy and stable fixation is a feasible option to improve anatomic and functional problems of severely malrotated humeral shaft fractures.
文摘BACKGROUND Hip fractures and proximal humerus fractures are known to be associated with increased mortality,but the impact on mortality of combining these two common injuries is not well known.AIM To compare mortality,inpatient stay and discharge destination for patients with combined hip and proximal humerus fractures with those sustaining isolated hip fractures.METHODS Using the United Kingdom national hip fracture database,we identified all hip fracture patients over the age of 60 admitted to a single trauma unit from 2010-2016.Patients sustaining a proximal humerus fracture in addition to their hip fracture were identified using hospital coding data.We calculated the 30-d and one-year mortality for both the hip fracture cohort and the combined hip and proximal humerus fracture cohort.Other variables recorded included age,gender and whether the proximal humerus was treated with or without an operation.RESULTS We identified 4131 patients with hip fractures within the study period and out of those 40 had sustained both a hip and a proximal humerus fracture.Mean age in the hip fracture cohort was 80.9 years and in the combined fracture group 80.3 years.Out of the 40 patients in the combined group four were treated operatively.The 30-d mortality for our hip fracture cohort was 7.2%compared to the mortality of our combined cohort of 12.5%(P=0.163).The one-year mortality for our hip fracture cohort was 26.4%compared to 40%for the combined fracture cohort(P=0.038).We also found patients with combined injuries were less likely to return to their own home.CONCLUSION The 30-d and one-year mortality is higher for those patients who have sustained a combined hip and proximal humerus fracture when compared to those with a hip fracture alone.
文摘Aim of the present study is to investigate the efficacy and safety of TachoSil? to reduce afterbleeding and hematoma following operative treatment of proximal humerus fractures. In a prospective randomized study we included a consecutive series of 40 patients with a proximal humeral fracture in this study. All fractures were stabilized surgically with a fixed-angle “Philos plate” from May 2008 through May 2009. All patients were divided in two groups: Group I with plate osteosynthesis without TachoSil, Group II with plate osteosynthesis with TachoSil. For statistical analysis Chi2- Test and U- Test were used. There were 4 perioperative complica- tions in group II and one complication in group I (Chi2-Test: p=0.233). In group II one hardware failure occurred due to osteoporosis requiring revision and reosteosynthesis. Another patient suffered from paralysis of the radial nerve which healed uneventfully. One superficial postopera-tive infection and one superficial hematoma re-quired revision surgery, too. In this group no subfascial hematoma developed. One subfascial hematoma which required no revision occurred in group I. Blood transfusion was required 2 times in group I and 3 times in group II (Chi2-Test: p = 0.549). In sum in group II there was a sig-nificant lower blood loss for the subfascial drain, the region where TachoSil was applied. No ad-verse affects related to TachoSil could be de-tected. TachoSil was found to be safe and effective for reduction of postoperative bleeding following operative treatment of proximal hume-rus fractures. Further studies with larger sample size are required to confirm the efficacy of TachoSil? in orthopedic surgery.
文摘Plate osteosynthesis of humeral shaft fractures is an established surgical procedure. Iatrogenic radial nerve palsy appears to be common complication in treating these fractures. A case series of 20 fracture shafts of humerus were treated with anteromedial plating through anterolateral approach. There was no radial nerve palsy in any of the cases and all achieved fracture union.
文摘Background: Pediatric supracondylar humerus fractures are the most common elbow fractures in children. Operative management includes closed reduction and placement of 2 to 3 laterally based pins. Occasionally, a medial pin is used to create a crossed fixation pattern, despite risk of nearly 10% iatrogenic ulnar nerve injury. The objective of this study was to assess the trends and outcomes in the operative management of pediatric supracondylar humerus fractures at a level one academic trauma center. Materials & Methods: A retrospective review was performed on all children sustaining a Gartland type II or III supracondylar humerus fractures treated by closed or open reduction and percutaneous pinning in 2006-2008 and 2009-2011 at a level one academic trauma center by two of the authors (JTR, LMT). Pin placement patterns were evaluated and compared based on year performed. Outcomes measured were rates of ulnar nerve symptoms, non-union, re-operation, and varus malalignment. Data analysis was performed using a Fisher exact test on STATA software. Results: A total of 49 patients met inclusion criteria. Of 22 patients treated in 2006-2008, 5 (23%) were type II and 17 (77%) were type III. From 2009-2011, 16 (59%) were type II and 11 (41%) were type III. Comparison of pinning pattern in type II fractures between 2006-2008 and 2009-2011 did not indicate statistical significance (p = 0.429). Comparison of pinning pattern in type III fractures during the same time period did show that there was a statistically significant decrease (p = 0.010) in the number of cross pin fixations. There were no ulnar nerve injuries, non-unions, re-operations, or varus malalignment in any patient on final follow-up. Conclusion: This study shows that there has been a significant decrease in cross pin fixation for pediatric type III supracondylar humerus fractures with equivalent clinical outcomes at a Level I trauma center. Furthermore, performing lateral pinning for type III fractures has eliminated the risk of iatrogenic ulnar nerve injury. Level of Evidence: Level III—Retrospective cohort study.
文摘The distal interlocking is regarded as an inherent part of the antegrade humeral nailing technique. Traditionally the distal locking of intramedullary humeral nails is achieved using a freehand technique. The humerus nailing locking options in the conventional nailing systems are placed in the anterior-posterior and lateral-medial directions. It exposes both the patient and surgeon to radiation, is time consuming, and has a potential risk of damaging neurovascular structures, especially the radial and lateral cutaneous nerve when the anterior-posterior and lateral-medial locking constructs are used. We aim to present a technical tip to ease the distal locking procedure and avoid the possible neurovascular complications with the existing nailing systems.
