Acetabular posterior wall fracture. 38 cases followed for 5 years

Abstract

Thirty-eight patients with a fracture of the posterior wall of the acetabulum were reviewed after 5 (2-12) years. Of 18 patients with successful manual reduction of a femoral head dislocation, a small fracture fragment, no sciatic nerve injury and who were not operated on, 17 had a good result. Of 20 patients who were operated on either because of the large size of the fracture fragment or because of a persistent dislocation of the femoral head, 6 had a poor result due to femoral head necrosis. In these 6 patients the reduction had been delayed and the acetabular osteochondral lesion was more severe than in the other patients. Skeletal traction seems unnecessary in the treatment of acetabular posterior wall fracture.
