AbstractWe reviewed 37 patients with avascular necrosis of the femoral head (ANF). There were 23 men and 14 women with a mean age of 36 years at the time of the operation. The duration of follow-up was 9 years. Twenty patients had undergone transtrochanteric rotational osteotomy (TRO) and 17, hip arthroplasties. Assessment of their quality of life (QoL) was performed using the Rosser Index Matrix for disability and distress. Concerning TRO, the mean preoperative and postoperative QoL scores were 0.944 and 0.957, respectively. Twelve patients exhibited increases and 7 patients decreases in their scores. Regarding the arthroplasty, the mean preoperative and postoperative QoL scores were 0.949 and 0.998, respectively. All patients showed increases in QoL scores after arthroplastic surgery. Concerning heavy manual work, all five of those patients returned to their preoperative occupations. These findings suggest that hip arthroplasty has more reliable therapeutic effects than TRO on QoL improvement for patients with ANF.
