The purpose of this study was to evaluate the prevalence of acetabular dysplasia in an asymptomatic Asian population as one of the most important risk factors of hip osteoarthritis. From December 2014 to March 2015, we investigated the data of 200 asymptomatic volunteers (400 hips) aged 18-50 years recruited from our institution. Pelvic radiographs were taken and reviewed by two experienced orthopaedic surgeons. Lateral centre-edge (LCE) angle, Sharp angle, Tonnis angle and acetabular depth-to-width ratio (AD/WR) were measured. We investigated the mean values and identified the statistical differences between the sexes and evaluated the prevalence and bilaterality of acetabular dysplasia defined by each parameter. Mean LCE angle, Sharp angle, Tonnis angle and AD/WR were 26.2°, 41.3°, 8.5° and 0.28, respectively. All parameters showed more dysplastic results in females than in males and were statistically significantly different, except for AD/WR. When defined acetabular dysplasia as LCE angle <20°, Sharp angle >45°, Tonnis angle >14° or AD/WR <0.25, the prevalence of acetabular dysplasia by each parameter was 15.0%, 12.8%, 13.3% and 12.8%, respectively. There was a higher prevalence in females than in males; however, only Sharp and Tonnis angles showed significant differences. The bilaterality of acetabular dysplasia was 18.6-39.5% for all subjects. There is high prevalence of asymptomatic dysplastic hips in the Asian population.
本研究的目的是评估无症状亚洲人群中髋臼发育不良的患病率，其为髋骨关节炎最重要的危险因素之一。2014年12月至2015年3月，我们调查了从本机构招募的200名年龄在18至50岁之间的无症状志愿者（400个髋关节）的数据。拍摄骨盆X光片并由两位经验丰富的骨科医生进行评估。测量了外侧中心边缘（LCE）角、夏普角、托尼斯角和髋臼深宽比（AD/WR）。我们调查了平均值，确定了性别之间的统计学差异，并评估了每个参数所定义的髋臼发育不良的患病率和双侧性。平均LCE角、夏普角、托尼斯角和AD/WR分别为26.2°、41.3°、8.5°和0.28。除AD/WR外，所有参数在女性中的发育不良结果均比男性更多，且具有统计学显著差异。当将髋臼发育不良定义为LCE角<20°、夏普角>45°、托尼斯角>14°或AD/WR<0.25时，每个参数所定义的髋臼发育不良的患病率分别为15.0%、12.8%、13.3%和12.8%。女性患病率高于男性；然而，只有夏普角和托尼斯角显示出显著差异。所有受试者髋臼发育不良的双侧性为18.6%至39.5%。亚洲人群中无症状发育不良髋关节的患病率较高。
