摘要
背景:骨关节炎(OA)是成人髋关节最常见的疾病，其病因分为原发性和继发性两组。虽然髋臼发育不良是日本全髋关节置换术(THA)最常见的原因，但近年来原发性骨关节炎有所增加。虽然原发性骨关节炎有两种类型的股骨头移位:上移位和内侧移位，但也有一些患者股骨头偏侧突出。本研究旨在利用影像学指标评估原发性髋关节骨关节炎患者股骨头偏侧与髋臼和股骨近端骨形态之间的关系。方法:2008年至2017年进行回顾性研究，对我院1308例骨关节炎患者行原发性髋关节置换术进行评估。原发性骨关节炎的诊断标准为Crowe 1型，夏普角25°。我们根据股骨头侧化将原发性OA患者分为两组:有侧化的L组和没有侧化的N组。影像学因素包括夏普角、CE角、髋臼倾角、髋臼深度比(ADR)、髋臼头指数(AHI)和股骨颈轴角(FNA)，均在骨盆正位x线片上检查。利用计算机轴位断层扫描计算股骨颈前倾。结果:原发性骨关节炎患者为210/1308髋(16.1%)(L组:112髋(8.6%);N组:98(7.5%))。患者人口统计数据无显著差异。L组与N组的放射学因素有显著差异的是平均CE角(33.0°vs. 35.1°，p = 0.009)，不良反应(251.6 vs. 273.4, p p p = 0.012)。结论:本研究表明原发性骨关节炎伴股骨头偏侧在髋臼和股骨近端表现出特定的可识别的影像学特征，这可能导致髋关节不稳定，如髋关节发育不良。
Correlation between Femoral Head Lateralization and Bone Morphology in Primary Hip Osteoarthritis.
Background: Osteoarthritis (OA) is the most common disease of the hip in adults, and its etiology is divided into two groups: primary and secondary. Although acetabular dysplasia is the most frequent reason for total hip arthroplasty (THA) in Japan, primary OA has increased recently. Although there are two types of femoral head migration in primary OA: superior and medial, there are some patients with prominent femoral head lateralization. This study aimed at evaluating the relationship between femoral head lateralization and bone morphology of the acetabulum and proximal femur using radiographic factors in primary OA of the hip.
Methods: A retrospective study was conducted between 2008 and 2017 to assess 1308 hips with OA who underwent primary THAs at our institute. The diagnostic criteria for primary OA were Crowe type 1, Sharp's angle <45°, and center-edge (CE) angle >25°. We classified patients with primary OA into two groups based on femoral head lateralization: group L with lateralization or group N without. Radiographic factors included Sharp's angle, CE angle, acetabular inclination, acetabular depth ratio (ADR), acetabular head index (AHI), and femoral neck-shaft angle (FNA), all examined on an anteroposterior pelvic radiograph. Femoral neck anteversion was calculated using computerized axial tomography.
Results: Primary OA was diagnosed in 210/1308 hips (16.1%) (group L: 112 hips (8.6%); group N: 98 (7.5%)). Patient demographics were not significantly different. Radiographic factors with observed significant differences between group L and group N were the average CE angle (33.0° vs. 35.1°, respectively, p = 0.009), ADR (251.6 vs. 273.4, p < 0.001), AHI (77.2 vs. 80.4, p < 0.001), and FNA (136.9° vs. 134.8°, p = 0.012).
Conclusions: This investigation suggests that primary OA with femoral head lateralization demonstrated specific identifiable radiographic characteristics in the acetabulum and proximal femur that might contribute to hip joint instability such as the dysplastic hip.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
