Remodelling of the femoral head after proximal femoral osteotomy for avascular necrosis associated with slipped capital femoral epiphysis.

Avascular necrosis is the most devastating complication associated with slipped capital femoral epiphysis. In this case report, we present the clinical and radiological outcome of two patients after proximal femoral osteotomy for avascular necrosis associated with slipped capital femoral epiphysis. The Iowa hip score was used to assess the function. Periodic radiographic observations showed no progression of the collapse, and bone remodelling of the necrotic femoral head. Our evaluation of patients who underwent proximal femoral osteotomy for avascular necrosis prior to collapse of the femoral head suggests that its use resulted in acceptable clinical outcome with bone remodelling of the necrotic area (Fig. 4, Ref. 16).
