髋关节发育不良（DDH）通常被描述为由于髋臼前外侧缺陷导致股骨头覆盖面积减少。虽然覆盖范围缩小是DDH的特征，但关节更细微和局部的解剖特征也被认为有助于症状的发展和退变。使用传统方法很难识别这些特征。在此，我们使用关节统计形状模型（SSM）评估了全股骨和半骨盆的形态。该模型确定了日本女性人群中与DDH相关的形态和姿势变化，并确定了哪些变化预测了覆盖率。来自47名患者的83个髋关节的计算机断层图像被分割输入到基于对应的SSM中。模型中的主要变化模式最初表示比例和姿态。在通过个体骨对准去除这些因素后，股骨型和颈轴角、骨盆曲度和髋臼型是观察到的主要变化。我们发现股骨头的扁度和髋臼边缘的突出度以及股骨和半骨盆的各种肌肉附着部位可以预测基于3D ct的覆盖测量（全骨R2= 0.5-0.7，关节R2=0.9）。
Developmental dysplasia of the hip (DDH) is commonly described as reduced femoral head coverage due to anterolateral acetabular deficiency. Although reduced coverage is the defining trait of DDH, more subtle and localized anatomic features of the joint are also thought to contribute to symptom development and degeneration. These features are challenging to identify using conventional approaches. Herein, we assessed the morphology of the full femur and hemi-pelvis using an articulated statistical shape model (SSM). The model determined the morphological and pose-based variations associated with DDH in a population of Japanese females and established which of these variations predict coverage. Computed tomography images of 83 hips from 47 patients were segmented for input into a correspondence-based SSM. The dominant modes of variation in the model initially represented scale and pose. After removal of these factors through individual bone alignment, femoral version and neck-shaft angle, pelvic curvature, and acetabular version dominated the observed variation. Femoral head oblateness and prominence of the acetabular rim and various muscle attachment sites of the femur and hemi-pelvis were found to predict 3D CT-based coverage measurements (R2=0.5–0.7 for the full bones, R2=0.9 for the joint).
