Possible ways of improving the stability of the fragments of the femur under elongation by introducing hybrid implant systems (the Kirschner wires and the Schanz screws) into the Ilizarov fixator structure were explored. Experimental studies were conducted on physical models with the fixator mounted on a pipe section modelling the femur shaft. Ten modifications of the Ilizarov fixator were developed and tested. The designs differed in the kind and configuration of implants. The effect of the developed Ilizarov fixator designs was examined by comparing the coefficients of axial, transversal and torsional rigidity of the structures. The research results clearly show that the Ilizarov fixator's rigidity (particularly transverse rigidity) coefficients can be considerably increased by replacing the Kirschner wires with the Schanz screws or using hybrid systems of these implants. As a result, the stability of the femur fragments improves and so does the quality of the regenerated bone, which makes it possible to reduce the treatment time to a minimum.
探索了通过在伊里扎洛夫固定器结构中引入混合植入系统（克氏针和斯氏针）来提高股骨延长段稳定性的可能方法。在将固定器安装在模拟股骨干的管段上的物理模型上进行了实验研究。开发并测试了伊里扎洛夫固定器的十种改进方案。这些设计在植入物的种类和配置上有所不同。通过比较结构的轴向、横向和扭转刚度系数，研究了所开发的伊里扎洛夫固定器设计的效果。研究结果清楚地表明，用斯氏针代替克氏针或使用这些植入物的混合系统，可以显著提高伊里扎洛夫固定器的刚度（特别是横向刚度）系数。结果，股骨碎片的稳定性提高，再生骨的质量也提高，这使得治疗时间能够缩短到最短。
