Early acetabular protrusio following hemiresurfacing of the hip for osteonecrosis in sickle cell disease.
A case report is presented of a patient with acetabular protrusio 2 years following hemiresurfacing of the femoral head for osteonecrosis associated with sickle cell disease. Renewed interest in bone-preserving hip arthroplasty has led to increased use of hemiarthroplasty and femoral resurfacing in young patients with arthritis. In cases of osteonecrosis, especially that associated with sickle cell disease, awareness of this potential complication is important.
