Case 11. A 22-year-old male patient had a traumatic acetabular fracture combined with an ipsilateral intertrochanteric fracture in his right hip. The patient underwent open reduction and internal fixation surgery for both his acetabulum and proximal femur. Then, 2.2 years after surgery, avascular necrosis of the right femoral head was detected, and revision with total hip arthroplasty was performed. a Anterior-posterior view immediately after injury. b Computed tomography image showing avascular necrosis of the right femoral head. c Anterior-posterior view before hip arthroplasty. d Lateral view before hip arthroplasty. e Anterior-posterior view after hip arthroplasty. f Lateral view after hip arthroplasty
