Protrusio Acetabuli


This is a 56 year old female who presented with a unique hip disorder called protrusio acetabuli. Both her hips had worn medially (inwards) through the inner wall of the hip socket. She was unable to perform normal daily activities such as walking more than two blocks, getting in and out of a car, or having intercourse.


She underwent staged bilateral complex total hip replacements over three months. The femoral head was used as autograft (the patient’s own bone graft) in the protrusio defect, and the anatomic hip centers were restored.


At one year postoperatively, the patient is now leading a normal life with no limitations or pain.
