- Posterior wall of the acetabulum – most common
- Indications for operative intervention are Hip instability demonstrated on EUA, Hip incongruency due to intra-articular fragments, Fractures involving >50% of the posterior wall
- Dynamic fluoroscopic stress testing under general anaesthesia should be the preferred method for the determination of hip stability status after posterior wall fractures of the acetabulum
- Kocher Langenbock Approach used to fix posterior wall fractures
- Complications following surgical fixation are injury to sciatic nerve , heterotopic ossification and Osteonecrosis of the femoral head
