To investigate radiographic measurements of the hip joint and their associations with hip pain, and the prevalence of acetabular dysplasia defined by radiographic measurements of the hip joint in Japanese men and women using the large-scale population-based cohort of the Research on Osteoarthritis/osteoporosis Against Disability (ROAD) study.
From the baseline survey of the ROAD study (cross-sectional study), 2963 participants (1040 men, 1923 women; mean age, 70.2 years) were analyzed. All participants underwent radiographic examinations of both hips using an anteroposterior view under weight-bearing. Minimum joint space width (mJSW), central-edge (CE) angle, acetabular depth-to-width ratio (ADR), and acetabular head index (AHI) were measured. Associations between these radiographic measurements and hip pain were assessed by calculating odds ratios (ORs) using multivariable logistic-regression analysis. Acetabular dysplasia was defined as a CE angle <20°.
Mean radiographic measurements of the hip joint for men were: mJSW, 3.8 mm; CE angle, 30.6°; ADR, 262.1 per 1000; and AHI, 81.4%. For women, these values were: mJSW, 3.4 mm; CE angle, 29.9°; ADR, 262.7 per 1000; and AHI, 81.2%. Associations were seen between hip pain and each of mJSW, CE angle, ADR, and AHI (OR 4.52, 95% confidence interval 3.45-5.97; 1.14, 1.11-1.18; 1.31, 1.24-1.40; and 1.15, 1.12-1.18, respectively). Acetabular dysplasia showed an overall prevalence of 13.9%, and was significantly more prevalent in women than in men (P = 0.012).
The present study of radiographic measurements of the hip joint showed that mJSW, CE angle, ADR, and AHI were associated with hip pain.
通过大规模基于人群的研究骨关节炎/骨质疏松性疾病致残疾（ROAD）研究的基线调查（横断面研究），调查髋关节的影像学测量值及其与髋关节疼痛的关系，并确定使用髋关节影像学测量值定义的日本男性和女性髋臼发育不良的患病率。
从 ROAD 研究的基线调查中（横断面研究），分析了 2963 名参与者（1040 名男性，1923 名女性；平均年龄 70.2 岁）。所有参与者均采用负重前后位进行双侧髋关节 X 线检查。测量最小关节间隙宽度（mJSW）、中心边缘（CE）角、髋臼深度与宽度比（ADR）和髋臼头指数（AHI）。使用多变量逻辑回归分析计算比值比（OR）评估这些影像学测量值与髋关节疼痛之间的关系。髋臼发育不良定义为 CE 角<20°。
男性髋关节的平均影像学测量值为：mJSW，3.8mm；CE 角，30.6°；ADR，每 1000 个 262.1；AHI，81.4%。女性这些值分别为：mJSW，3.4mm；CE 角，29.9°；ADR，每 1000 个 262.7；AHI，81.2%。髋关节疼痛与 mJSW、CE 角、ADR 和 AHI 均有关联（OR 分别为 4.52、95%置信区间 3.45-5.97、1.14、1.11-1.18、1.31、1.24-1.40 和 1.15、1.12-1.18）。髋臼发育不良的总体患病率为 13.9%，女性明显高于男性（P=0.012）。
本研究通过髋关节影像学测量发现，mJSW、CE 角、ADR 和 AHI 与髋关节疼痛有关。
