结论：软组织张力异常是假体脱位的主要原因。
Conclusion: Abnormal soft-tissue tension has become the main causes of dislocation after total hip replacement.
人体软组织具有重要地位，软组织纤维化和增生、肥厚等多种原因能够使软组织发生相对运动障碍、张力增高、长度缩短、腔隙内压增高等改变。
The fibrosis, hyperplasia, and hypertrophy of soft tissues can cause the change of soft tissue in relative motion disorder, tension increase, length shorten, lacuna pressure increase.
