Introduction: Traumatic posterior hip dislocation with comminuted fracture of the ipsilateral acetabulum and femoral neck is a rare fracture pattern. These injuries are associated with high energy trauma and pose challenges during management. Controversy exists between hip preservation and replacement surgeries in middle-age patients. Open reduction and internal fixation (ORIF) have a high risk of non-union, avascular necrosis, and post-traumatic osteoarthritis of hip requiring total hip arthroplasty hip replacement (THA) as a secondary procedure later.
Case Report: A 56-year-old male presented with posterior hip dislocation and comminuted fracture of ipsilateral wall and column of the acetabulum, and femoral neck following a high energy trauma. He was managed by acetabular reconstruction using femoral head structural autograft combined with acute primary uncemented THA. At 2-year follow-up, the patient had good functional outcome with a satisfactory range of motion without any difficulty in weight-bearing and doing his daily activities.
Conclusion: Although uncommon, acetabular reconstruction using femoral head structural autograft and acute primary uncemented THA is a viable alternative treatment option compared to ORIF in middle-age patients with fracture of ipsilateral neck and acetabulum. This facilitates post-operative rehabilitation and avoids further operations for possible developing AVN or secondary arthritis.
