摘要： 目的 研究股骨重度骨缺损、肢体短缩患者矫形器的设计制作方法、生物力学作用、实用性以及对患者平衡、行走功能及步态的影响。方法 针对6例股骨重度骨缺损、肢体短缩患者设计制作矫形器，制作过程共经历4个阶段，最终制成假脚型坐骨承重矫形器，进而分析矫形器的生物力学作用、实用性，并评价患者的平衡、行走能力和步态。结果 假脚型坐骨承重矫形器符合生物力学原理，实现患者不拄拐行走，患者穿戴矫形器后能量消耗比拄拐时小，平衡功能有明显改善，步行距离参数接近正常。结论 假脚型坐骨承重矫形器可帮助股骨重度骨缺损、肢体短缩患者实现独立行走，有推广意义。

Abstract: Objective To study the design and fabricating method, biomechanical effect and practicablity of the orthosis for patients suffering from large femoral bone defect and leg length discrepancy and study the effect of the orthosis on patients' equilibrium, walking function and gait. Methods By four stages we finally made ischial weight bearing orthosis with prosthetic feet, and then analysed its biomechanical effect and efficiency, evaluated balance and walking function of patients.Results The orthosis, according with principle of biomechanics, realized patients' wish of walking without crutch. The energy consumption and balanced capacity of patients wearing orthosis were much better while walking distance parameters came close to normal. Conclusion Ischial weight bearing orthosis with prosthetic feet can help patients reconstruct walking function, therefore can be recommended.
