Kinematic gait analysis was carried out on 42 hips, including normal joints and joints affected with Legg-Calvé-Perthes disease. Data were analyzed by a computer algorithm that calculated three-dimensional femoral head contact with the acetabulum (containment). Patients were studied in and out of various abduction orthoses. The three-dimensional containment of the hip is reproducibly altered by various devices; specifically, the Atlanta brace increases posterior coverage and slightly increases lateral coverage, and Petrie casts improve lateral and anterior coverage at the expense of posterior containment. This analysis allows modeling of osteotomies and enhances clinical assessment of actual changes in containment with bracing.
对42个髋关节进行了运动步态分析，包括正常关节和患有Legg-Calvé-Perthes病的关节。数据通过一种计算机算法进行分析，该算法计算股骨头与髋臼的三维接触（包容度）。对患者在各种外展矫形器使用期间及停用后进行了研究。各种装置可重复性地改变髋关节的三维包容度；具体而言，亚特兰大支具增加了后方覆盖并略微增加了外侧覆盖，而皮特里石膏以牺牲后方包容度为代价改善了外侧和前方覆盖。该分析允许对截骨术进行建模，并增强了对支具使用时包容度实际变化的临床评估。
