Acute total hip arthroplasty versus open reduction internal fixation for posterior wall acetabular fractures in middle-aged patients.

OTA Int 2019 Mar 12;2(1):e014. Epub 2019 Mar 12.

Orthopaedic Surgery, Hennepin County Medical Center, Minneapolis, Minnesota.

Introduction: Open reduction internal fixation (ORIF) is the standard of care for displaced acetabular fractures, but the inability to achieve anatomic reduction, involvement of the posterior wall, articular impaction, and femoral head cartilaginous injury are known to lead to poorer outcomes. Acute total hip arthroplasty (THA) is a reasonable treatment option for older patients with an acetabular fracture and risk factors for a poor outcome, but it is only described in case series. The purpose of this study is to compare outcomes of ORIF and acute THA in middle-aged patients with an acetabular fracture from a single center. Read More
