The reasons are discussed for differences in functional results of the pelvic osteotomy after Chiari, regardless of the fact that the CE and AC angles were equal in all patients. When lateralization and distal displacement of the greater trochanter were performed in addition to the pelvic osteotomy, the functional results proved to be better. Biomechanical analysis of the relationship between gluteal force and body weight revealed that these relations change; in all examined cases where lateralization and distal displacement of the greater trochanter were performed, the relationship proved postoperatively to be considerably more favorable. In the same group of patients, the relationship between the force of reaction and body weight was also changed after surgery. Therefore, lateralization and distal displacement of the greater trochanter are important factors for the undisturbed functioning of a hip; in all examined patients the functional results were better when lateralization and distal displacement of the greater trochanter were performed.
尽管所有患者的CE角和AC角均相等，但仍对Chiari术后骨盆截骨术功能结果存在差异的原因进行了讨论。当除骨盆截骨术外还进行大转子外移和远侧移位时，功能结果证明更好。对臀肌力量与体重之间关系的生物力学分析表明，这些关系发生了变化；在所有进行大转子外移和远侧移位的检查病例中，术后这种关系证明更为有利。在同一组患者中，术后反应力与体重之间的关系也发生了变化。因此，大转子外移和远侧移位是髋关节正常功能的重要因素；在所有检查的患者中，进行大转子外移和远侧移位时功能结果更好。
