Avascular necrosis of the femoral head--an unusual complication of an intertrochanteric fracture.
Avascular necrosis of the femoral head is an uncommon complication after intertrochanteric fracture. We report six patients with this unusual complication 1-5 years after intertrochanteric fracture. The possible etiologies of this complication include a more proximal intertrochanteric fracture, a high-energy injury with fracture displacement resulting in vascular damage, and adverse influences of the operative procedures on the vascularity of the femoral head.
