Periacetabular osteotomy (PAO) is a well established method to treat hip dysplasia in the adult. There is, however, a lack of information on the subjective outcome of patients with complications after PAO. The purpose of this study was therefore to assess the influence of complications on the patients' post-operative wellbeing and function: 60 PAOs on 50 patients were investigated retrospectively after a mean follow-up of 7.4 years. The patients' self-reported assessment of health and function was evaluated by the Medical Outcomes Short Form-36 (SF-36) and the Western Ontario and McMaster Universities (WOMAC) questionnaires at last follow-up. Forty healthy persons served as a control group. Of the 60 interventions 13 had no complications. Minor complications occurred in 25 (41%) and in 22 (37%) at least one major complication occurred. SF-36 summary measure was 76.4 for PAO patients and 90.3 for the control group. Mean WOMAC score was 25.1. Patients with major complications had a similar subjective outcome as patients with minor or without complications, but persistent dysaesthesia due to lateral femoral cutaneous nerve dysfunction led to a worse subjective function. Lesions of the lateral femoral cutaneous nerve have much greater influence on patients' self-assessed functional outcome after PAO than previously reported and greater attention has to be given to this supposedly minor complication.

髋臼周围截骨术 (PAO) 是治疗成人髋关节发育不良的公认方法。但是,缺乏有关PAO术后并发症患者的主观结果的信息。因此,本研究的目的是评估并发症对患者术后健康和功能的影响: 平均随访7.4年后,对50例患者的60个pao进行了回顾性调查。在最后的随访中,通过医疗结果简表36 (SF-36) 以及西安大略和麦克马斯特大学 (WOMAC) 问卷对患者的自我报告的健康和功能评估进行了评估。40名健康人作为对照组。在60种干预措施中,有13种没有并发症。轻微并发症发生在25 (41%) 和22 (37%) 中,至少发生了一种主要并发症。PAO患者的SF-36总结措施为76.4,对照组为90.3。平均WOMAC得分为25.1。有重大并发症的患者的主观结局与有轻微或没有并发症的患者相似,但是由于股外侧皮肤神经功能障碍而导致的持续感觉障碍导致主观功能恶化。PAO术后股外侧皮神经病变对患者自我评估功能结果的影响比以前报道的要大得多,因此必须对这种所谓的轻微并发症给予更多关注。
