The osteoporotic acetabular fracture.

Fractures of the acetabulum are some of the most challenging fractures that face orthopedic surgeons. In geriatric patients, these challenges are enhanced by the complexity of fracture patterns, the poor biomechanical characteristics of osteoporotic bone, and the comorbidities present in this population. Nonsurgical management is preferable when the fracture is stable enough to allow mobilization, and healing in a functional position can be expected. When significant displacement and/or hip instability are present, operative management is preferred in most patients, which may include open reduction and internal fixation with or without total hip arthroplasty.
