The purpose of this study was to determine if there is an anatomic relationship between pelvic geometry and acetabular depth.
One hundred and fifty-one anteroposterior pelvic radiographs (157 hip joints) were selected and analyzed in a retrospective fashion. Six parameters, including iliac offset, ischial offset, acetabular offset, pelvic height, center-edge (CE) angle of Wiberg, and acetabular index (AI) angle of Tönnis were measured for each of the hip joints. Based on the defined variables, three formulas (formulas 1, 2, and 3) were calculated to represent the hemi-pelvis slope.
There was a strong relationship between the hemi-pelvis slope and probability of acetabular dysplasia. Wider upper pelvis was associated with deeper acetabulum and wider lower pelvis was associated with dysplastic acetabulum.
Pelvic anatomic dimensions and the relationship between them are strongly correlated with hip dysplasia indices. Dysplastic hips tend to be found in pelvises with lower slope (low width of the upper pelvis at the level of iliac crest and high width of the lower part at the level of ischium).
本研究旨在确定骨盆几何形状与髋臼深度之间是否存在解剖学关系。
回顾性选取并分析了151张骨盆前后位X线片（157个髋关节）。对每个髋关节测量六个参数，包括髂骨偏移、坐骨偏移、髋臼偏移、骨盆高度、维伯格中心边缘（CE）角和托尼髋臼指数（AI）角。基于定义的变量，计算了三个公式（公式1、2和3）来表示半骨盆倾斜度。
半骨盆倾斜度与髋臼发育不良的可能性之间存在密切关系。骨盆上部较宽与髋臼较深相关，骨盆下部较宽与髋臼发育不良相关。
骨盆解剖尺寸及其相互关系与髋关节发育不良指数密切相关。发育不良的髋关节往往出现在倾斜度较低的骨盆中（髂嵴水平处骨盆上部宽度低，坐骨水平处下部宽度高）。
