[Operative treatment of displaced acetabular fractures through the ilioinguinal approach].

To reduce the incidence of ectopic ossification and improve hip joint function after the operative treatment of displaced acetabulum fractures. We surgically treated 12 acetabular fractures which involved anterior column or both anterior and posterior column fractures through the ilioinguinal approach. 10 patients were judged postoperatively to have an anatomic reduction, and 2 had a satisfactory reduction. An average of 3-year follow-up showed excellent results in 8 patients (67%) and good in 4 (33%). Radiographic results indicated excellent results in 8 (67%), patients good in 3 (25%), fair in 1 (8%). The results suggested that the ilioinguinal approach appears to diminish many of the problems associated with utilization of an extrapelvic approach, including the disturbances of the hip abductor system, heterotopic ossification, sciatic palsy, the slow recovery of hip mobility. We conclude that it is not only good for an operative treatment of anterior column fractures but also good for some of posterior column fractures.
