Potential complications associated with acetabulum fractures include post-traumatic arthritis, ectopic bone formation, and avascular necrosis of the femoral head (lack of blood supply that will cause the bone to die).

A Total Hip Replacement, an operation in which the hip joint is replaced with an artificial joint, is often used to repair damage caused by arthritis. This is a good solution for older patients. However, because the durability of artificial joints is limited (causing joint failure within approximately 15 years), younger patients will need at least one subsequent replacement in their lifetime. And though results are good with the first implant, subsequent replacements often do not work as well.

To prevent or reduce the risk of future complications, patients are advised to have regular follow-ups at minimal cost to them. Arrangements to see other doctors may be made for patients who live outside California.

• 34 percent had excellent results with fully restored hip function
• 45 percent returned to work and walk well but refrain from participation in vigorous sport and activities
• 8 percent experienced impaired hip function, but have not yet required further surgery
• 13 percent showed poor hip function which significantly impaired movement, often necessitating further surgery

The extent of recovery after surgery sometimes depends on other injuries associated with the trauma, the location and severity of the fracture, and the age and general condition of the patient. Most patients with poor results have suffered complicated fractures and other related injuries.
