| Abstract: | One hundred two patients with 105 displaced fractures of the acetabulum were treated for fractures involving at least one column of the acetabulum and displaced at least 5 mm (rim fractures were excluded). The patients were primarily young adults with multiple injuries secondary to motor-vehicle-associated trauma. Fractures were classified according to the classification of Letournel. The most common fractures were the complex associated types with 44 complete both column, 19 T-shaped, and 18 associated transverse and posterior wall. Seventeen fractures were treated closed, and 88 were treated operatively. Closed treatment with skeletal traction was undertaken if roof arc measurements demonstrated a satisfactory remaining acetabular dome following fracture and in some cases of apparent congruence following complete both column fractures. Fractures not meeting these criteria were operated upon through the Kocher-Langenbeck, extended iliofemoral, or ilioinguinal approach. Ninety percent of the operations produced a satisfactory reduction of the fracture (3 mm or less displacement). A follow-up study longer than one year was obtained for 50 fractures. Clinical results were 80% satisfactory overall. Operative complications included 3% infection, 5% nerve palsy, and 7% significant ectopic bone. Operative treatment can produce satisfactory fracture reductions and clinical results with an acceptably low complication rate. |
