Only a limited number of patients that suffered from Legg-Calvé-Perthes' disease (LCPD) develop pain in early adulthood. Classical hinged abduction is well known and is thought to be responsible for secondary lateral insufficiency of the acetabulum, which may become painful. Another possible explanation, which was put forward more recently, is anterior femoroacetabular impingement. We collected...

Background. The combination of Dega transililiac and femoral subtrochanteric is used in our department in the treatment of Legg-Calvé-Perthes' disease. Subtrochanteric osteotomy, initially performed as varus-derotation osteotomy, is now mainly extension osteotomy with shortening. Femoral shortening is crucial for joint decompression and makes room for pelvic redirection after pelvic osteotomy. ...

In this paper we wish to emphasise the danger of avascular necrosis of the capital femoral epiphysis arising as a late complication of osteomyelitis of the intertrochanteric region. This necrosis is primarily aseptic and is believed to follow interference with the vulnerable vascular channels supplying the capital femoral epiphysis rather than spread of infection into the joint. If, however, th...
