INTRODUCTION The end of medial opening oblique wedge high tibial osteotomy (HTO) points into a narrow area between the articular cartilage of the posterolateral proximal tibia and proximal tibiofibular joint (PTFJ) at the tibial site, which is an anatomical safe zone (ASZ) for osteotomy. We studied the ASZ and its relation to the fibular tip, including the level of posterior cruciate ligament (...

BACKGROUND This article reports outcome in osteotomy for malunion of distal radius fractures. MATERIAL AND METHODS We evaluated 12 patients with distal radius malunion (mean age 54), who were treated with corrective osteotomy. Wrist motion and grip strength were evaluated, along with examination of pre and post osteotomy radiographs. The indications for corrections were degree of deformity, l...

Corrective osteotomy of the distal radius for malunion has always been a challenging procedure. Deformity involves length, angulation and rotation. Planning an osteotomy on plain x-rays is difficult and in-exact. Reproducing that planned osteotomy in the operating theatre is even more difficult. Attempts to improve accuracy with the use of CT scanning and even the production of models have met ...

The paper describes the technique and application of a tricortical bone graft harvesting from lateral malleolus. Graft does not interfere with continuity fibula. Due to its structure, is equivalent similarly structured taken iliac crest. used in osteotomies arthrodesis within foot ankle joint, which require strong piece as wedge. author typically uses this type for osteotomy anterior part calca...

The use of standing radiographs to determine correction angles for high tibial osteotomy is not appropriate because the relative angle of the articular surfaces (condylar-plateau angle) in the weight-bearing knee changes after the osteotomy. This may give unpredictable results postoperatively. We found that the condylar-plateau angle in postoperative standing films is very similar to that seen ...

One hundred and forty-five stifles of client-owned dogs that underwent corrective surgery for congenital medial patellar luxation were inspected for cartilage erosion on the articular surface of the patella. The lesions were mapped in surface percentage ranges of 20% and by location. Two-thirds of the patellae had cartilage erosion. Cartilage erosion varied between 0 and 100% of the total patel...

PURPOSE Periacetabular osteotomy (PAO) has become an accepted treatment option for patients with severe hip dysplasia. In addition to correcting acetabular architecture, consideration has been given to concomitant joint evaluation and treatment of coexisting intra-articular pathologic conditions, which can be identified with hip arthroscopy or through an open arthrotomy. The purpose of this sys...

Excessive femoral anteversion may lead to increasing stress placed on the anterior acetabulum and soft tissues, which can predispose to intra-articular hip pathology. By addressing the excessive femoral anteversion in combination with intra-articular hip pathology, the results will be durable over time. This technique details how to perform a femoral derotation osteotomy for excessive femoral a...
