ilateral sagittal split osteotomy (BSSO) is commonly used n the correction of dentofacial deformities. However, in cases f facial asymmetry with a shift of the mandibular midline r occlusal cant, the condyle is displaced laterally by the ulling of the proximal segment medially when there is bony nterference between the proximal and distal segments after he osteotomy. When the gap between the pr...

BACKGROUND AND AIMS The aim of this study is to evaluate the effect of proximal tibia osteotomy on hip biomechanics. METHODS This cohort study was conducted on 50 knees of 37 patients divided into two groups of unilateral and bilateral surgeries during 2015-2016. Patients underwent medial open-wedge osteotomy of proximal tibia. Axial alignment of lower limb radiography was carried out for the...

We compared 74 total hip arthroplasties (THAs) carried out after previous proximal femoral osteotomy with a diagnosis-matched control group of 74 primary procedures performed during the same period. We report the perioperative results and the clinical and radiological outcome at five to ten years. We anticipated a higher rate of complications in the group with previous osteotomy, but found no s...

Background: An increased femoral anteversion angle (FAA) is a predisposing factor for recurrent patellar dislocations (RPDs), and combined procedures including derotational distal osteotomy (DDFO) have been shown to be good options. Purpose: To investigate the safety effectiveness of DDFO on clinical radiological outcomes treat RPDs with an FAA. Study Design: Systematic review; Level evidence, ...

triphalangeal thumb is characterized by the interposition of an extra-phalanx between two normal ones. in this article the authors present the case of a 24-year-old man with bilateral triphalangeal thumb of opposable type, without any other associated anomaly or genetic syndrome. the patient had triangular delta extra-phalanxes that caused ulnar deviation of both thumbs. surgical procedure for ...

BACKGROUND The treatment of complex diaphyseal malunions is challenging, requiring extensive preoperative planning and precise operative technique. We have developed a simpler method to treat some of these deformities. METHODS Ten patients with complex diaphyseal malunions (including four femoral and six tibial malunions) underwent a clamshell osteotomy. The indications for surgery included p...

The aetiology and form of hallux valgus (HV) is varied with many corrective procedures described. We report a 39-year-old woman, previously treated with a Chevron osteotomy, who presented with recurrent right HV, metatarsus primus varus, and associated bunion. Osteotomies were performed at two levels as a revisional procedure. This report highlights (1) limitations of the Chevron osteotomy and ...

Intra-articular osteotomy is considered in the rare case of malunion after a fracture of the distal humerus to restore humeral alignment and gain a functional arc of elbow motion. Traumatic and iatrogenic disruption of the limited blood flow to the distal end of the humerus resulting in avascular necrosis of capitellum or trochlea is a major pitfall of the this technically challenging procedure...
