本文阐述了一种治疗股骨头缺血性坏死的新方法的生物力学问题。已进行了数值计算的旋转屈曲截骨术的髋关节的数学模型，考虑到主要的一组肌肉。这项工作提出的计算结果和分析。并与临床资料进行了比较。对髋臼和股骨近端部分产生的反作用力的计算使我们能够揭示该反作用力在值和方向上都发生变化。这些数据可能有助于评估骨科介入中使用的外固定器械的刚度和评估关节中的压缩。
The paper formulates the problem of biomechanics of a new method for treatment of Legg-Calve-Perthes disease. Numerical calculations of the rotational flexion osteotomy have been carried out for a constructed mathematical model of the hip joint, taking into account the main set of muscles. The work presents the results of the calculations and their analysis. The results have been compared with the clinical data. The calculations of the reactive forces arising in the acetabulum and the proximal part of the femur allowed us to reveal that this reactive force changes both in value and direction. These data may be useful for assessing the stiffness of an external fixation device used in orthopedic intervention and for evaluating the compression in the joint.
