【摘要】 本文报告应用测力台测试平衡固定牵引架,治疗股骨干骨折21例患者下地时负重的动、静态力学参数。结果表明:在骨折康复过程中从生物力学的观点看,双拐是早期下地的一个重要力学因素。当去除牵引时,患肢负重力恢复到66%,这时不应该过早去掉拐杖,仍需小夹板局部外固定。更多还原

【Abstract】 The patients with femur fracture,who were treated by balanced fixed traction frame,could move about in early stage,In order to explore its mechanism and the tendency of femur fracture recovery,21 patients have been measured.The measurements include dynamic and static measure- ment.The technique of gravity measuring platform has been used.Through the measurement,we could find that,in early stage,the loading power of fractured leg was about 10 kg.Most of the weight was undertaken by the crutches.In the early stage of moving,crutches were important for loading. When the traction was removed,the loading power of wounded leg reached 66% of normal,so it is still necessary to retain the fixation of small splint and the support of crutches.更多还原
