Eighty-seven of patients were operated on with bipolar hip prosthesis in the last 4 years. 38 of them were followed up for clinical and radiological evaluations. Although postoperative follow-up period is short, all of the patients have had no pain in the hip joint and showed recovery of hip movement.
Radiologically, the movility of the inner bearing was lost in nine of the 38 hips, showing one-piece movement. This seems likely to happen in more than two years after surgery, but has no relation with clinical results.
