Quality of life improvement after transtrochanteric rotational osteotomy of avascular necrosis of the femoral head

We studied 20 patients with avascular necrosis of the femoral head (ANF) before and after transtrochanteric anterior rotational osteotomy (TARO). There were ten male and ten female patients who were 20 to 55 years old (mean, 33 years old) at the rime of the operation. Disability and distress were assessed by the Harris hip score, which was used to generate Qualify of life (QoL) scores using the Rosser Index Matrix. Twelve patients increased their QoL scores, and one had no change. Seven patients decreased their scores, and four of them subsequently needed a total hip arthroplasty. ?he median preoperative and postoperative score was 0.892 (range, 0.870 to 0.986) and 0.960 (range, 0.870 to 1.000) respectively. There was no statistically significant difference in the improvement in QoL scores between the preoperative and postoperative. These findings could suggest that TARO indication for ANF patients should be determined based on more strict criteria.
