Although medial, superior, and axial patterns of migration of the femoral head in osteoarthritis of the hip have been well described, it is not clear what anatomic and biomechanical factors determine the direction of migration. The authors studied 22 patients with bilateral (11 patients) or unilateral (11 patients) osteoarthritis by means of conventional radiography and computed tomography (CT) to define any relationships between migration in the coronal plane and that in the transverse plane and to determine whether femoral anteversion, acetabular anteversion, femoral neck-shaft angle, or acetabular inclination were related to particular migration patterns. Anterior migration was evident in 14 of the 19 hips with a superior migration pattern, whereas posterior migration was present in five of the seven hips with a medial migration pattern. In the remainder of cases, no migration in the transverse plane was present. Femoral anteversion as determined with CT, femoral neck-shaft angle, angle of acetabular inclination, and acetabular anteversion angle in this relatively small sample were all found to be within normal limits and appeared to have no influence on the occurrence of a specific pattern of femoral head migration.
尽管在髋关节骨关节炎中股骨头的内侧、上方和轴向移位模式已有详尽描述，但尚不清楚是哪些解剖学和生物力学因素决定了移位方向。作者通过传统X线摄影和计算机断层扫描（CT）对22例双侧（11例）或单侧（11例）骨关节炎患者进行研究，以确定冠状面移位与横断面移位之间的任何关系，并确定股骨前倾角、髋臼前倾角、股骨颈干角或髋臼倾斜度是否与特定的移位模式相关。在19例具有上方移位模式的髋关节中，14例出现向前移位，而在7例具有内侧移位模式的髋关节中，5例出现向后移位。在其余病例中，横断面未出现移位。在这个相对较小的样本中，通过CT测定的股骨前倾角、股骨颈干角、髋臼倾斜角和髋臼前倾角均在正常范围内，似乎对股骨头特定移位模式的发生没有影响。
