BACKGROUND Scaphoid malunion alters the carpal kinematics and impairs clinical outcome because of pain, weakness, restricted range of motion and predisposing the wrist joint to early osteoarthritis. The aim of this study was to evaluate the influence of the scaphoid morphological angles on clinical outcomes in patients with reconstructed scaphoid by non-vascularized bone graft. METHODS Sevent...

PURPOSE To assess the results of a hybrid Russe procedure using a corticocancellous strut, cancellous autologous nonvascularized bone graft, and cannulated headless compression screw to reduce the deformity reliably from a collapsed scaphoid nonunion, provide osteoinductive stimulus, and stabilize the fracture for predictable union. METHODS A hybrid Russe procedure was performed for scaphoid ...

BACKGROUND Vascularized bone-grafting pedicled on 1,2 intercompartmental supraretinacular artery (1,2 ICSRA) has been recommended as a treatment alternative for established scaphoid nonunion complicated with proximal pole avascular necrosis (AVN). Previous reports focused the studies on the union rate and the revascularization of the transferred graft. However, the postoperative wrist stiffness...

تشخیص لنگش های بند سوم که از مهترین علت های لنگش در اسب می باشد نیاز به فهم یافته های نرمال رادیوگرافی بند سوم دارد. از آنجایی که تاکنون اطلاعات دقیقی در مورد اندازه ها و زوایای بند سوم در اسب عرب خون داخلی به دست نیامده و مقایسه ای با نژادهای دیگر اسب ها صورت نگرفته است. در این تحقیق سعی شده است که خصوصیات بیومتریک بند سوم دست اسب عرب اصیل توسط رادیولوژی مورد بررسی قرار گیرد. در این تحقیق 10 ...

PurposeWe evaluated the impact of structural versus nonstructural bone grafting on time to union, scaphoid deformity correction, and clinical outcomes in adults with unstable waist nonunion without avascular necrosis. We hypothesized that would provide earlier restoration anatomy, equivalent compared grafting.MethodsWe prospectively randomized 98 patients undergo open reduction, iliac crest eit...

background: abnormal angulation of the lunate can be an indication of intercarpal pathology. on magnetic resonance images (mris) the lunate often looks dorsally angulated, even in healthy wrists. the tilt on individual slices can also be different and might be misinterpreted as pathological, contributing to inaccurate diagnoses and unnecessary surgery. the primary aim of this study was to deter...

conclusions although some of the orthopedic surgeons are not interested to manage these fractures surgically and most of them treat these cases conservatively (casting, etc.), in most displaced intra-articular calcaneal fractures, surgical treatment is the method of choice. moreover, in non-surgical treatment the prevalence of these complications among the patients is more and as a result, inev...
