title: Acetabular fractures in the elderly: evaluation and management.
abstract: Acetabular fracture patterns in the elderly, with increased involvement of the anterior column, quadrilateral plate comminution, medialization of the femoral head, and marginal impaction, differ from those noted among a younger cohort. Poor prognostic factors for open reduction and internal fixation (ORIF) are posterior wall comminution, marginal impaction of the acetabulum, a femoral head impaction fracture, a so-called gull sign, and hip dislocation. The rate of conversion to total hip arthroplasty following formal ORIF has been reported to be 22% at a mean of twenty-nine months. Total hip replacement after an acetabular fracture generally yields good clinical results; however, in the acute setting, it must be combined with proper stable fracture fixation.
