背景：骨关节炎是一种使人衰弱的疾病，其发展途径尚不清楚。髋关节、骨盆和股骨的形态和位置参数与个体差异或疾病状态的变化有关，在诊断和治疗患者时应考虑这两个因素。这些尚未全面量化。以前的成像研究受到许多因素的限制;仰卧而不是站立测量;高辐射剂量;有限的视野; 2D而不是3D测量。EOS（R）是一种新的放射成像模式，可同时采集全身的正面和侧面（矢状）X射线图像，可对髋关节、骨盆和下肢进行3D重建。本研究的目的是探讨健康和骨关节炎groups.Methods之间的异同：两组受试者，30名健康和30髋关节骨关节炎，进行了评估和比较骨盆，髋臼和股骨参数在站立position.Findings：不仅有组间的显着差异，但也有相当大的重叠之间的个人。骨关节炎组骶骨倾斜度、Idelberger和Frank髋臼角、股骨机械角、股骨头偏心率、髋臼中心角和股骨头直径的左右不对称性均高于健康对照组，而髋臼外展度低于健康对照组（P < 0.05）。两组中关键参数之间的相关性被确定。解释：组间差异表明随着时间的推移或可能导致疾病进展的个体之间的固有差异的退行性变化。这些数据为纵向和术后研究提供了基础。由于个体之间存在相当大的变异性，组间存在相当大的重叠，因此在计划髋关节、膝关节和脊柱手术时，应对患者进行单独评估和多关节评估。(C)2014爱思唯尔有限公司版权所有。
Background: Osteoarthritis is a debilitating disease, for which the development path is unknown. Hip, pelvis and femoral morphological and positional parameters relate either to individual differences or to changes in the disease state, both of which should be taken into account when diagnosing and treating patients. These have not yet been comprehensively quantified. Previous imaging studies have been limited by a number of factors; supine rather than standing measurements; high radiation dose; a limited field of view; and 2D rather than 3D measurements. EOS (R), a new radiographic imaging modality that acquires simultaneous frontal and lateral (sagittal) X-ray images of the full body, allows 3D reconstruction of the hip, pelvis and lower limb. The aim of the study was to explore similarities and differences between healthy and osteoarthritis groups.Methods: Two groups of subjects, 30 healthy and 30 with hip osteoarthritis, were assessed and compared for pelvic, acetabular and femoral parameters in the standing position.Findings: There were not only significant differences between groups but also considerable overlap amongst the individuals. Sacral slope, acetabular angle of Idelberger and Frank, femoral mechanical angle and femoral head eccentricity as well as right-left asymmetries in centre-edge acetabular angle and femoral head diameter were higher on average in osteoarthritic patients compared to healthy subjects, whereas acetabular abduction was lower in the osteoarthritic group (P < 0.05). Correlations were identified between key parameters in both groups.Interpretation: Differences between the groups suggest either degenerative changes over time or inherent differences between individuals that may contribute to the disease progression. These data provide a basis for longitudinal and post-surgery studies. Due to the considerable variability amongst individuals and the considerable overlap between groups, patients should be evaluated individually and at multiple joints when planning hip, knee and spine surgery.
