[Fractures of the acetabulum: complications and joint replacement].

Acetabular fractures assume a special role amongst the fractures of the pelvis, because they involve a major weight-bearing joint. As those fractures mostly result from exposure to great force, and because of their location in an anatomically complex region, a high rate of complications has to be anticipated. Besides general and perioperative complications long-term consequences, especially post-traumatic arthrosis, are relevant problems when it comes to treating fractures of the acetabulum. The primary reconstruction of the acetabulum, as well as a possibly necessary prosthetic replacement of the hip joint, makes high demands on the diagnostic and operative capabilities of the attending physician. Exact knowledge of the specific risks and pitfalls for each type of fracture and for the specific surgical techniques is crucial for a successful treatment. Due to the much worse long-term outcome when compared to primary total hip replacement in patients with osteoarthritis, acetabular fractures should, regardless of the patient's age, whenever possible be treated by operative reconstruction.
