To quantify error, 3 orthopedic surgeons visually estimated preoperative knee flexion contractures from lateral digital images of 23 patients prior to and after surgical draping. A repeated-measure analysis of variance was used to compare the estimated angles prior to and following the placement of the surgical drapes with the true knee angle measured with a long-arm goniometer. In an effort to reduce the error of visual estimation, a dual set of inclinometers was developed to improve intraoperative measurement of knee flexion contracture during TKA. A single surgeon performed 6 knee extension measurements with the device during 146 consecutive TKA cases. Three measurements were taken with the desired tibial liner trial thickness, and 3 were taken with a trial that was 2 mm thicker. An intraclass correlation coefficient(ICC) was calculated to assess the testretest reliability for the 3 measurements taken with the desired liner thickness, and a paired t test was used to determine if the knee extension measurements differed when a thicker tibial trial liner was placed.RESULTS: The surgeons significantly overestimated flexion contractures in 23 TKAs prior to draping and significantly underestimated the contractures after draping(actual knee angle = 6.1°± 6.4°, pre-drape estimate = 6.9°± 6.8°, post-drape estimate = 4.3°± 6.1°, P = 0.003). Following the development and application of the measurement devices, the measurements were highly reliable(ICC = 0.98), and the device indicated that 2.7°± 2.2° of knee extension was lost with the insertion of a 2 mm thicker tibial liner. The device failed to detect a difference in knee extension angle with the insertion of the 2 mm thicker liner in 9/146 cases(6.2%).CONCLUSION: We determined the amount of error associated with visual estimation of knee flexion contractures, and developed a simple, reliable device and method to improve feedback related to sagittal alignment during TKA.展开更多

Rapid, effective and less complicated surgical methods can help patients with post-burn rehabilitation. Objective: This article argues that a modified Z-plasty can quickly improve the range of motion caused by webbed scar contractures in joint areas, including surgical methods, postoperative care and prognosis. Methods and Results: The study took place from 2018 to 2022. Thirty-two patients with joint scar contracture deformity, with a mean age of 32.5 years, were included in the study. All patients underwent contracture scar revision and modified Z-plasty repair under anesthesia. All the flaps survived and the joint function was improved. Compared with the traditional Z-plasty, the duration of the operative procedure of the modified Z-plasty was significantly shorter, more surrounding scar tissue was mobilized, and the effectiveness of postoperative scar contracture release was better. Discussions: The modified Z-plasty for scar contracture deformity in joint area is simple, rapid, effective and easy to manage.展开更多

These scars result in adduction deformity, which may be severe and diffuse. The lack of adequate treatment in the acute phase leads to complex scars that require different surgical techniques depending on the clinical examination of surgeon. Aim: Expose the possible surgical techniques, their advantages and disadvantages in the case of burning of the entire axillary hollow. The surgical management of linear scares contractures will not be discussed in this article. Case presentation: This is a rare clinical case of a 12-year-old girl who was burned at the age of 5 with disabling functional sequelae of the axillary area (limitation of the abduction to 30 degrees). The patient is treated at ALGHASSANI Hospital in Fes city/Morocco. Parental consent was taken for scientific publication. Results: We did two surgical interventions: the first starting with excision of the scar tissue leaving a loss of skin covered by a laterothoracic IC fasciocutaneous flap. The second one was a semi-thick skin graft to cover the supero and infero external quadrants of the left breast. We obtain the abduction at 110 degrees. Conclusion: Early surgical management of deep lesions within 21 days of the burn associated with prolonged rehabilitation and the wearing of compression garments and splints are essential elements in the prevention of these axillary contractures.展开更多

Surgical treatment may be indicated for those burn scar contractures. If the contractures are small and linear, the contraction bands can be treated with local transposition flaps like the Z-plasty. Broader, diffuse contractures are more challenging and require a different surgical approach, such as the use of local tissue. The use of perforator-based flaps is promising;however, their true clinical significance for this type of burn reconstructions still needs to be determined. Therefore, we performed a review to evaluate the role of perforator-based flaps for burn scar contracture treatment. Electronic databases were searched using a predefined search strategy. Studies evaluating the long-term outcome of perforator-based flaps for the treatment of burn scar contractures were included. The methodological quality was tested and data was summarized. Five hundred and ten papers were identified of which eleven met the inclusion criteria. One study was a randomized controlled trial;ten were cohort studies of a pre-postoperative design. The papers described outcomes of free flaps and local flaps. Most studies had methodological shortcomings and used inappropriate statistical methods. Perforator-based interposition flaps appear to be highly relevant for burn scar contracture treatment. However, due to the paucity and low quality of the studies that were assessed, no definitive conclusions about the true clinical significance could be reached. And therefore, only recommendations could be given for improvement of the quality of further primary research on the effectiveness of perforator-based flaps for burn scar contracture release.展开更多

Varieties of techniques are available for resurfacing defects following contracture release but graft or flap loss, donor-site morbidity, esthetics, and recurrences are still challenges for reconstructive surgeons. Central axis 'propeller' flaps based on a random, subcutaneous pedicle were first described for axillary and elbow contractures to deploy the unburnt skin of axillary dome in type Ⅰ and Ⅱ contractures (Kurtzman and Stern) by moving them 90° to straddle the contracting bands. This strategy provided better esthetics and avoided prolonged splinting. Over more than two decades, there have been several design modifications of these flaps with extended applications to cubital fossa. A comprehensive review of published literature on the topic is presented to discuss classifications, design modifications, and applications of such flaps in managing axillary and elbow contractures.展开更多

It can cause both pain and dysfunction if not treated adequately (1)The treatment of such wounds often involves a combination of surgery and splinting therapy (2)A variety of splints, including the thermoplastic static neck splint [3], the Watusi collar [4], manually fabricated splints, and pre-fabricated splints such as the Philadelphia collar have been used for the management of scar contractures. However, each type of splint has its own advantages and disadvantages, and none of these splints seem to reduce the need for skin reconstruction nor delays the time until surgical re-construction [5].展开更多

Methods： A retrospective cohort study was conducted in which all cases of knee contractures managed with Judet＇s quadricepsplasty from 1st January 2009 to 31st December 2013 were included and were divided into two groups. The epinephrine group included patients who were infiltrated with diluted epinephrine （1：400,000） along with xylocaine, around the operative field 15 min prior to the incision time, while the control group did not receive any infiltration. Judet＇s outcome, blood loss, drop in he- moglobin and required blood transfusion were noted for all patients and compared between both groups. Results： Most common preceding pathology identified for the development of knee contractures was periarticular fracture while ilizarov application was the most common etiology. Both groups were found similar in all preoperative characteristics except preoperative flexion contracture （p = 0.02）. All func- tional outcome measures including Judet＇s outcome were similar in both groups. In contrast, duration of surgery （p = 0.01）, blood loss （p = 0.02）, drop in hemoglobin （p = 0.01） and number of transfusions （p = 0.03） were significantly reduced in epinephrine group. Conclusion： Judet＇s quadricepsplasty is a useful procedure to increase the range of motion of rigid knees and local infiltration of epinephrine is effective in decreasing the amount of subsequent blood loss and transfusion requirements.展开更多

Methods: In May 2020, the patient noticed an increase in the size of a breast mass. In August, she underwent AC-THP neoadjuvant chemotherapy, followed by a “right breast-conserving nipple-areolar subglandular excision + right axillary lymph node dissection + expander implantation” surgery in November 2020. Radiation therapy began in January 2021. During radiation therapy, the patient experienced severe breast hardening, distortion, tenderness, and was diagnosed with Grade IV capsular contracture. To relieve the capsular contracture, the patient underwent a “contracted capsule incision and release procedure + removal of the right breast expander + right breast implantation” surgery in July 2021. Postoperatively, measures were taken to prevent incision infection, emphasizing aseptic techniques, ensuring smooth negative pressure drainage, reducing skin flap tension, monitoring skin flap blood supply, actively preventing subcutaneous effusion and hematoma, and applying appropriate compression dressings. Results: The patient was discharged after the removal of the drainage tube. During the postoperative follow-up at 3 and 6 months, there was no recurrence of capsular contracture, and the breast appeared full, upright, and relatively soft. There were no complications such as hematoma, infection, breast implant rupture, breast sagging, or displacement. The patient had a good outcome without additional financial or surgical burdens. Conclusion: The occurrence of Grade IV capsular contracture in the patient is generally related to infection after Stage I expander implantation, improper compression dressing, excessive saline injection causing content infiltration, and radiation therapy. Therefore, it is recommended to enhance the intraoperative and postoperative prophylactic use of antibiotics after Stage I expander implantation. Intermittent saline injection after surgery, with the amount of saline gradually increasing rather than filling all at once, is advisable. This helps the breast tissue gradually adapt to expansion, reducing the risk of capsular contracture. Postoperatively, patients should be instructed to wear pressure garments and breast elastic bandages while intensifying breast monitoring during radiation therapy and increasing postoperative follow-up.展开更多

Orthosis is widespread and varies widely in forms. The paper arises the necessity of habilitation at the earliest possible stage as only a few patients use it. The meta-analysis of 412 scientific papers concerning this problem demonstrates the getting better gate, balance and the stopping CMT progression which is scientifically proven. It is also shown that patients with CMT use low prevalence of orthotics, and demonstrate low compliance of patients (for various reasons), high expectations from this habilitation technique.展开更多

The patients with severe symptoms were asked to have a set of specially-designed functional exercises. All the patients were followed up for 3 to 24 months by hospital visit, correspondence or telephone interview. The effective rate was 100%, and the curative rate was up to 94.6%. Few patients developed complications and relapse was rare. It is concluded that the combination therapy, including surgical removal of diseased tissues, functional exercises and physical therapy, is an effective approach for the treatment of severe juvenile gluteal muscle contracture.展开更多

文摘BACKGROUND Juvenile arthritis damage index(JADI)is a tool that measures the degree of aggressiveness of the juvenile idiopathic arthritis(JIA)course and assesses articular[JADI-articular damage(JADI-A)]and extraarticular[JADI-extraarticular damage(JADI-E)]damage.While aggressive JIA often requires early bio-logic disease-modified antirheumatic drugs(bDMARDs),the utility of JADI as a predictor of treatment response remains underexplored.AIM To evaluate the potential of JADI as a predictor of bDMARD treatment response in JIA patients.METHODS This prospective study included 112 highly active non-systemic JIA biologic-naïve patients with a mean age of 12.2±4.6 years and a median disease duration of 2.5(interquartile range:1-5)years.Their clinical and radiological assessment,juvenile arthritis disease activity score 71,JADI-A,and JADI-E,were evaluated twice:Before the biologic initiation(baseline)and 12 months after(end of study).At baseline,50%had any damage,with 43%with articular damage and 23%with extraarticular damage.RESULTS During the study,JADI-A/JADI-E improved(33.9%/9.8%),worsened(8.9%/5.4%),or remained unchanged(57.1%/84.8%).Patients with baseline damage had higher markers of JIA activity:Polyarticular course,earlier onset age,ANA-positivity,and more active joints.Patients without initial structural damage(JADI“-”)were more likely(odds ratio=3.8,95%confidence interval:1.6-9.0,P<0.004)to achieve a low degree of activity or remission(46.2%),while on biological therapy,their scores were comparable to JADI-positive(18.3%).Pre-biological joint damage according to the JADI-A index(P=0.003),wrist(P=0.035),elbow(P=0.027),cervical spine limitation of motion(P=0.051),and erosions confirmed by magnetic resonance imaging(P=0.002),were associated with poor response to biological treatment and follow-up JIA activity.CONCLUSION Baseline structural damage in JIA is associated with diminished bDMARDs efficacy,increased disability,and shorter remission duration.JADI enhances conventional clinical risk stratification by facilitating timely initiation of bDMARDs,adherence to treat-to-target strategy and tailored patient care.

文摘Breast augmentation with implants is a popular cosmetic surgery that enhances breast volume and contour through various placement planes.In this review,we examine the impact of subglandular,subpectoral,and subfascial implant planes on postoperative outcomes and complication rates.Subglandular placement offers simplicity but is associated with higher risks of capsular contracture,hematoma,and rippling in patients with low tissue coverage.The subpectoral plane,widely adopted for its natural appearance and reduced capsular contracture risk,may cause dynamic deformity due to muscle contraction.Although technically challenging,the subfascial plane combines the benefits of soft tissue support and reduced implant displacement.We highlight the importance of choosing an optimal implant plane tailored to each patient’s anatomical and aesthetic needs to enhance surgical outcomes and minimize complications.Further research is needed to validate long-term efficacy,particularly for subfascial placement.

文摘Background:Joint contracture is the major clinical complication in burn patients,especially,the severe burn patients.This study aimed to investigate the number and severity of joint contractures in patients with burns affecting greater than or equal to 50%of the total body surface area(TBSA)undergoing early rehabilitation in a burn intensive care unit(BICU).Methods:We analyzed burn patients with burns affecting greater than or equal to 50%of the TBSA admitted to a BICU who received early rehabilitation within 7 days post-injury from January 2011 to December 2015.Demographic and medical information was collected.The range of motion(ROM)of different joints was measured 1 month post-admission.Spearman’s correlation coefficient and logistic regression analysis was used to determine predictors of the presence and severity of contractures.Result:The average affected TBSA of the included burn patients was 67.4%,and the average length of stay in the BICU was 46.2±28.8 days.One hundred and one of 108 burn patients(93.5%)developed at least one joint contracture.The ROM in 67.9%of the affected joints was mildly limited.The majority of contractures in severe burn patients were mild(37.7%)or moderate(33.2%).The wrist was the most commonly affected joint(18.2%),followed by the shoulder,ankle,hip,knee,and elbow.A predictor of the presence of contractures was the length of hospital stay(p=0.049).The severe contracture was related to the area of full-thickness burns,the strict bed rest time,and the duration of rehabilitation in BICU.The length of rehabilitation stay(days)in patients with moderate contracture is 54.5%longer than that in severe contracture(p=0.024)Conclusion:During the long stay in BICU,the length of rehabilitation stay in a BICU could decrease the severity of contractures from severe to moderate in the patients with equal to 50%of the TBSA.Hence,this research reveals the important role of early rehabilitation interventions in severe burn patients.
文摘Patients with burn scars often experience functional problems because of scar contractures. Surgical treatment may be indicated for those burn scar contractures. If the contractures are small and linear, the contraction bands can be treated with local transposition flaps like the Z-plasty. Broader, diffuse contractures are more challenging and require a different surgical approach, such as the use of local tissue. The use of perforator-based flaps is promising;however, their true clinical significance for this type of burn reconstructions still needs to be determined. Therefore, we performed a review to evaluate the role of perforator-based flaps for burn scar contracture treatment. Electronic databases were searched using a predefined search strategy. Studies evaluating the long-term outcome of perforator-based flaps for the treatment of burn scar contractures were included. The methodological quality was tested and data was summarized. Five hundred and ten papers were identified of which eleven met the inclusion criteria. One study was a randomized controlled trial;ten were cohort studies of a pre-postoperative design. The papers described outcomes of free flaps and local flaps. Most studies had methodological shortcomings and used inappropriate statistical methods. Perforator-based interposition flaps appear to be highly relevant for burn scar contracture treatment. However, due to the paucity and low quality of the studies that were assessed, no definitive conclusions about the true clinical significance could be reached. And therefore, only recommendations could be given for improvement of the quality of further primary research on the effectiveness of perforator-based flaps for burn scar contracture release.
文摘Contractures of the axilla and elbow can produce a significant impact on quality of life by reducing the ability to perform activities of daily living. Varieties of techniques are available for resurfacing defects following contracture release but graft or flap loss, donor-site morbidity, esthetics, and recurrences are still challenges for reconstructive surgeons. Central axis 'propeller' flaps based on a random, subcutaneous pedicle were first described for axillary and elbow contractures to deploy the unburnt skin of axillary dome in type Ⅰ and Ⅱ contractures (Kurtzman and Stern) by moving them 90° to straddle the contracting bands. This strategy provided better esthetics and avoided prolonged splinting. Over more than two decades, there have been several design modifications of these flaps with extended applications to cubital fossa. A comprehensive review of published literature on the topic is presented to discuss classifications, design modifications, and applications of such flaps in managing axillary and elbow contractures.
文摘Dear Editor,Burn scar contracture is a common problem in healing burn wounds of the neck. It can cause both pain and dysfunction if not treated adequately (1)The treatment of such wounds often involves a combination of surgery and splinting therapy (2)A variety of splints, including the thermoplastic static neck splint [3], the Watusi collar [4], manually fabricated splints, and pre-fabricated splints such as the Philadelphia collar have been used for the management of scar contractures. However, each type of splint has its own advantages and disadvantages, and none of these splints seem to reduce the need for skin reconstruction nor delays the time until surgical re-construction [5].
文摘Objective： To evaluate the effectiveness ofJudet＇s quadricepsplasty for treatment of knee contractures and to identify the effect of local infiltration of epinephrine on blood loss associated with this procedure. Methods： A retrospective cohort study was conducted in which all cases of knee contractures managed with Judet＇s quadricepsplasty from 1st January 2009 to 31st December 2013 were included and were divided into two groups. The epinephrine group included patients who were infiltrated with diluted epinephrine （1：400,000） along with xylocaine, around the operative field 15 min prior to the incision time, while the control group did not receive any infiltration. Judet＇s outcome, blood loss, drop in he- moglobin and required blood transfusion were noted for all patients and compared between both groups. Results： Most common preceding pathology identified for the development of knee contractures was periarticular fracture while ilizarov application was the most common etiology. Both groups were found similar in all preoperative characteristics except preoperative flexion contracture （p = 0.02）. All func- tional outcome measures including Judet＇s outcome were similar in both groups. In contrast, duration of surgery （p = 0.01）, blood loss （p = 0.02）, drop in hemoglobin （p = 0.01） and number of transfusions （p = 0.03） were significantly reduced in epinephrine group. Conclusion： Judet＇s quadricepsplasty is a useful procedure to increase the range of motion of rigid knees and local infiltration of epinephrine is effective in decreasing the amount of subsequent blood loss and transfusion requirements.

文摘Objective: By observing the treatment and nursing care of a patient with Grade IV capsular contracture following breast cancer expander implantation and subsequent Stage II reconstruction, we aim to analyze the reasons for the formation of capsular contracture after Stage I expander implantation and prevent its recurrence following Stage II reconstruction. Methods: In May 2020, the patient noticed an increase in the size of a breast mass. In August, she underwent AC-THP neoadjuvant chemotherapy, followed by a “right breast-conserving nipple-areolar subglandular excision + right axillary lymph node dissection + expander implantation” surgery in November 2020. Radiation therapy began in January 2021. During radiation therapy, the patient experienced severe breast hardening, distortion, tenderness, and was diagnosed with Grade IV capsular contracture. To relieve the capsular contracture, the patient underwent a “contracted capsule incision and release procedure + removal of the right breast expander + right breast implantation” surgery in July 2021. Postoperatively, measures were taken to prevent incision infection, emphasizing aseptic techniques, ensuring smooth negative pressure drainage, reducing skin flap tension, monitoring skin flap blood supply, actively preventing subcutaneous effusion and hematoma, and applying appropriate compression dressings. Results: The patient was discharged after the removal of the drainage tube. During the postoperative follow-up at 3 and 6 months, there was no recurrence of capsular contracture, and the breast appeared full, upright, and relatively soft. There were no complications such as hematoma, infection, breast implant rupture, breast sagging, or displacement. The patient had a good outcome without additional financial or surgical burdens. Conclusion: The occurrence of Grade IV capsular contracture in the patient is generally related to infection after Stage I expander implantation, improper compression dressing, excessive saline injection causing content infiltration, and radiation therapy. Therefore, it is recommended to enhance the intraoperative and postoperative prophylactic use of antibiotics after Stage I expander implantation. Intermittent saline injection after surgery, with the amount of saline gradually increasing rather than filling all at once, is advisable. This helps the breast tissue gradually adapt to expansion, reducing the risk of capsular contracture. Postoperatively, patients should be instructed to wear pressure garments and breast elastic bandages while intensifying breast monitoring during radiation therapy and increasing postoperative follow-up.

文摘BACKGROUND Fetal akinesia deformation sequence(FADS)is a broad spectrum disorder with absent fetal movements as the unifying feature.The etiology of FADS is heterogeneous and mostly still unknown.A prenatal diagnosis of FADS relies on clinical features obtained by ultrasound and fetal muscle pathology.However,the recent advances of next-generation sequencing(NGS)can effectively provide a definitive molecular diagnosis.CASE SUMMARY A fetus presented after 24 wk and 6 d of gestation with absent fetal movements and multiple abnormal ultrasonographic signs.The mother had had a previous abortion due to a similarly affected fetus a year before.A clinical diagnosis of FADS was made.The parents refused cord blood examination and chose abortion.A molecular diagnosis of fetal muscle using NGS of genes found a compound heterozygous mutation in the MUSK gene:c.220C>T(chr9:113449410 p.R74W)and c.421delC(chr9:113457745 p.P141fs).CONCLUSION To our knowledge,this is the first report in China showing that a mutation in MUSK is associated with FADS.This supports previous finding that a lethal mutation of MUSK will cause FADS.A precise molecular diagnosis for genetic counseling and options for a prenatal diagnosis of FADS are very important,especially for recurrent FADS;this may also provide evidence for both prenatal and preimplantation genetic diagnoses.
文摘Charcot-Marie-Tooth (CMT) disease, which encompasses several hereditary motor and sensory neuropathies, is one of the most common neuro-muscular disorders. 80% of patients having CMT disease are diagnosed with per cavus deformity. Orthosis is widespread and varies widely in forms. The paper arises the necessity of habilitation at the earliest possible stage as only a few patients use it. The meta-analysis of 412 scientific papers concerning this problem demonstrates the getting better gate, balance and the stopping CMT progression which is scientifically proven. It is also shown that patients with CMT use low prevalence of orthotics, and demonstrate low compliance of patients (for various reasons), high expectations from this habilitation technique.
文摘Gradual distraction with an external fixator is a widely used treatment for severe postburn ankle contracture(SPAC).However,application of external fixators is complex,and conventional two-dimensional(2D)imaging-based surgical planning is not particularly helpful due to a lack of spatial geometry.The purpose of this study was to evaluate the surgical planning process for this procedure with patient-specific three-dimension-printed models(3DPMs).In this study,patients coming from two centers were divided into two cohorts(3DPM group vs.control group)depending on whether a 3DPM was used for preoperative surgical planning.Operation duration,improvement in metatarsal-tibial angle(MTA),range of motion(ROM),the American Orthopedic Foot and Ankle Society(AOFAS)scores,complications,and patient-reported satisfaction were compared between two groups.The 3DPM group had significantly shorter operation duration than the control group((2.0±0.3)h vs.(3.2±0.3)h,P<0.01).MTA,ROM,and AOFAS scores between the two groups showed no significant differences pre-operation,after the removal of the external fixator,or at follow-up.Plantigrade feet were achieved and gait was substantially improved in all patients at the final follow-up.Pin-tract infections occurred in two patients(one in each group)during distraction and were treated with wound care and oral antibiotics.Patients in the 3DPM group reported higher satisfaction than those in the control group,owing to better patient-surgeon communication.Surgical planning using patient-specific 3DPMs significantly reduced operation duration and increased patient satisfaction,while providing similar improvements in ankle movement and function compared to traditional surgical planning for the correction of SPAC with external fixators.
文摘Summary: The operation methods, clinical classification, postoperative function exercise of gluteal muscles contracture were investigated. Clinically and retrospectively, treatment of 1280 patients with gluteal muscles contracture, being subjected to a 'Z-shaped' release lengthening operation and efficiency exercise, was clearly standardized. All the cases were followed up from 3 months to 2 years with the effective rate being 100 %, the cure rate being 98. 5 %, the recent complications being 5%, and the far complications being 0. 2 %. It was concluded that the clear diagnosis combined with standarized operation and efficiency functional exercise could greatly improve the therapeutic effects of gluteal muscles contracture.
文摘To investigate the efficacy of a combination therapy on gluteal muscle contracture, 286 definitely diagnosed patients were subjected to surgical treatment, and then functional exercises and physical therapy. The patients with severe symptoms were asked to have a set of specially-designed functional exercises. All the patients were followed up for 3 to 24 months by hospital visit, correspondence or telephone interview. The effective rate was 100%, and the curative rate was up to 94.6%. Few patients developed complications and relapse was rare. It is concluded that the combination therapy, including surgical removal of diseased tissues, functional exercises and physical therapy, is an effective approach for the treatment of severe juvenile gluteal muscle contracture.
文摘BACKGROUND Joint stiffness after elbow surgery is not a rare complication,and is always accompanied by deformity.The causes of joint stiffness are multiple in different patients,and divided into intrinsic and extrinsic causes.Herein,we report an unusual case of posttraumatic elbow stiffness due to multiple and rare causes.CASE SUMMARY A 19-year-old male was hospitalized with the loss of motion of the left elbow for over ten years.Left limb computed tomography revealed left elbow stiffness with bony block and connection.The patient underwent surgery,and the etiology of joint stiffness was found to be a rare combination of common and uncommon causes.During an 18-mo follow-up period,the patient’s left elbow had normal motion and he was symptom-free.CONCLUSION However,this case combined with multiple and rare causes highlights that the patient with scar physique is likely to be accompanied with more severe soft tissue,nerve contracture,and heterotypic ossification,even during recurrence.
