A roentgenographic analysis of 204 acetabular fractures is presented. In addition, 64 displaced fractures (43 treated surgically) are evaluated clinically and roentgenographically (average follow-up period, 3.7 years). Most fractures can be adequately evaluated from anteroposterior and oblique roentgenograms of the pelvis. The roentgenographic and clinical results correlate closely. Fractures must be reduced to a displacement of 3 mm or less, in addition to congruent reduction of the femoral head with the weight-bearing dome of the acetabulum, to achieve a satisfactory clinical result. Most displaced fractures involve the weight-bearing dome and require surgery. With an intact weight-bearing dome, nonoperative treatment is considered. Quantification of this dome with three measurements termed the medial, anterior, and posterior roof arc obtained from the standard roentgenograms is valuable in determination of appropriate treatment for displaced acetabular fractures.
