Femoroacetabular impingement (FAI) has been suggested as a major cause of primary hip osteoarthritis (PHOA). We assessed the prevalence of FAI detected radiographically in a cohort that underwent total hip replacement (THR) for PHOA. Two radiologists independently assessed the retrospective preoperative radiographs (AP pelvis and lateral) of 82 subjects <55 years of age scheduled for THR. Subjects were categorized as: definite FAI, no FAI, and not possible to exclude FAI. Definite FAI was present in 36 % of subjects. FAI is common in young subjects undergoing THR for PHOA.
髋关节撞击症(FAI)被认为是原发性髋关节炎(PHOA)的主要病因。我们评估了一组因 PHOA 接受全髋关节置换术(THR)的患者中,经影像学检查发现的 FAI 的患病率。两位放射科医生对 82 名年龄<55 岁、拟行 THR 的患者的回顾性术前骨盆正位(AP)和侧位片进行了独立评估。受试者分为:明确的 FAI、无 FAI 和无法排除 FAI。36%的患者存在明确的 FAI。FAI 在因 PHOA 接受 THR 的年轻患者中较为常见。
