摘　　要：目的:探讨臀肌筋膜挛缩症的生物力学机制及其临床意义。方法:复习189例手术病人,通过7具新鲜下肢标本,模拟臀肌筋膜挛缩症,进行生物力学实验。结果:发现臀肌筋膜挛缩症髋关节力下降62%,臀大肌、臀中肌、臀小肌力分别下降17%,37%及60%。证实盆三角的力学作用对髋关节的影响不可低估,肌力的变化导致力学上的失衡。结论:挛缩症导致臀股杠杆失效,力臂丢失,不能形成主动力矩,患肢呈船浆划动,表现“八”字步、蛙氏位,这些生物力学实验结果为临床手术提供了理论依据。Objective:The bionmechanics pathogery and clinical significance of the glutaeus myofascial contracture(GMFC)had been studied.Methods:189 operated patients hand been reviewed.GMFC had been imitated by 7 fresh lower limb specimens,the biomechanics experiment had been taken.Results:through the experiment,the myodymnamia of hip joint of GMFC were found decreased by 62%,the musculus glutaeus maximus medius and mimius respectivsly decreased by 17%,37% and 60%.It is not underestimated that the mechanical effects of pelvi triangle exerted tremendons influencel on the muscle power of the hip joit.The mechanical imbalance had been coused by changing of the myodynamic.Conclusions:GMFC had made the glutaeus femoral lever failure,lost arm of force and not formed moment of force.The sick limb appeared “oardrifing step”,“splayfoot” and froleg position.The results of experiment of biomechanics had provided a theoratical basis for clinical operation.
