Hip dysplasia and femoroacetabular impingement may both lead to disability and hip osteoarthritis. The purpose of the current study was to compare the two entities in order to define differences in their clinical presentation.
The clinical presentation and WOMAC items, subscales and overall sum score were compared between 37 patients with femoroacetabular impingement and 37 patients with hip dysplasia.
The average duration of symptoms was 33.3 ± 31.6 months in patients with femoroacetabular impingement and 34.5 ± 39.0 months in patients with dysplasia (p = 0.885). The anterosuperior impingement test was positive in all patients with femoroacetabular impingement and in 92% of hip dysplasia patients (p = 0.061). Mean internal rotation and abduction was significantly less in patients with femoroacetabular impingement (p = 0.001 and 0.007). The WOMAC subscales for pain, stiffness, and functionality as well as the overall sum score were not significantly different between patients with femoroacetabular impingement and patients with hip dysplasia. The qualitative analysis of WOMAC items revealed that symptoms related to sitting were significantly more often rated to be present in femoroacetabular impingement than in hip dysplasia patients. In the quantitative analysis, only the item 'getting in or out of a car' was rated significantly more severe in patients with femoroacetabular impingement.
In addition to obtaining a detailed history and examination, radiographic studies are needed for differentiation of the two entities and for the decision on treatment strategy.
髋关节发育不良和股骨髋臼撞击症均可导致残疾和髋骨关节炎。本研究的目的是比较这两种疾病，以明确其临床表现的差异。
比较了 37 例股骨髋臼撞击症患者和 37 例髋关节发育不良患者的临床表现和 WOMAC 项目、子量表和总分。
股骨髋臼撞击症患者的平均症状持续时间为 33.3±31.6 个月，髋关节发育不良患者为 34.5±39.0 个月（p=0.885）。所有股骨髋臼撞击症患者和 92%的髋关节发育不良患者的前上撞击试验均为阳性（p=0.061）。股骨髋臼撞击症患者的内旋和外展角度明显小于髋关节发育不良患者（p=0.001 和 0.007）。WOMAC 疼痛、僵硬和功能子量表以及总分在股骨髋臼撞击症患者和髋关节发育不良患者之间无显著差异。WOMAC 项目的定性分析显示，与坐有关的症状在股骨髋臼撞击症患者中更为常见，而在髋关节发育不良患者中则不常见。在定量分析中，只有“上下车”这一项在股骨髋臼撞击症患者中被评为更严重。
除了详细的病史和检查外，还需要进行影像学研究来区分这两种疾病，并决定治疗策略。
