Background: There are few studies comparing the biomechanical properties of angled blade plate and locking compression plates in supracondylar osteotomy. In the current randomized study, we prospectively compared the clinical and radiological outcomes of supracondylar osteotomy using these two plates. Methods: Forty patients with valgus knee malalignment were randomly assigned to two equal nu...

conclusions closed reduction and hybrid external fixation can be used as a definitive treatment for severe comminuted fractures of the distal femur and proximal tibia, when the concomitant contusion of the skin and soft tissue damage prohibits safe open reduction and internal fixation. patients and methods in a prospective study, 44 patients with comminuted fractures of the distal femur or prox...

We describe 95 patients with previously treated congenital dislocation of the hip who underwent femoral osteotomy after the age of five years. The commonest indication for surgery was progressive uncovering and subluxation of the femoral head; other reasons were coxa vara, long leg dysplasia and persistent anteversion. Femoral osteotomy for uncovering of the femoral head (Severin Grade III) in ...

Dysplasia of the hip is characterized by malpositioning of the proximal femur in a shallow acetabulum, providing deficient femoral head coverage. This abnormal relationship leads to altered biomechanics of the hip joint, as predicted by measurement of kinematic parameters such as increased load over reduced acetabular weight-bearing area, leading to increased joint contact stresses, which subse...

During the initial fragmentation stage of Perthes disease, the principle focus is to achieve containment of the femoral head within the acetabulum. Whether by bracing, abduction casts, femoral and/or pelvic osteotomy, the goals are to maximize the range of hip motion and to avoid incongruity, hoping to avert subsequent femoro-acetabular impingement or hinge abduction. A more subtle and insidiou...

Intertrochanteric osteotomy may postpone the need for total hip replacement (THR). In young patients with an acquired deformity of the femoral head and secondary osteoarthritis, a valgus intertrochanteric osteotomy may allow better congruency but the acetabular cover may become insufficient because of subluxation of the femoral head. In patients with a spherical femoral head and acetabular dysp...
