A 12-year-old boy sustained a gunshot injury to the proximal femur. The bullet hole passed through the femoral neck very close to the proximal femoral physis (Ogden type 8 physeal injury) without neurovascular injury.
The boy was treated conservatively with antibiotics and bedrest. Nine months later, avascular necrosis of the femoral head (Ratliff type 2) and limb shortening of 2 cm had developed.
For this reason, a valgus intertrochanteric osteotomy was performed 1 year after the injury. However, only partial revascularization of a necrotic femoral head segment occurred.
For the residual necrotic segment in the weight-bearing area and progressive shortening of the femur 3.5 years after injury, a valgus-extension intertrochanteric osteotomy was performed and remodelling of the necrotic fragment done. The boy is now over 19 years old.
He has only minimal pain after sports activity and a slightly limited range of movement. The limb shortening is 1.5 cm.
