Symmetrical distribution of the load of the lower limbs and balance are among the determinants of proper biomechanics of the musculoskeletal system. So far, it has not been elucidated whether the correction of the axis and the equalization of the length of the lower limbs allow for achieving proper balance and load distribution. The aim of the present study was to compare load distribution and balance of patients who underwent Ilizarov method corticotomies with healthy controls.
The clinical studies evaluated 57 patients, who underwent corticotomy with the Ilizarov method. The control group consisted of 59 healthy volunteers. The evaluation assessed the distribution of the load of the lower limbs and balance using pedobarographic platform.
In the study group operated limb bore 48.02% of the load on average, while the healthy limb 51.98%. These differences were not statistically significant. The average percentage of load in limbs in treated and control groups did not differ significantly. In the study group, the average length of path of the center of gravity was 145.47cm. In the control group, the average length of path of the center of gravity was 112.69cm. In the study group, the average area of the center of gravity was 7.54cm(2), while in the control group it was 5.19cm(2).
Ilizarov method corticotomy allows for the obtainment value of the load distribution of the lower limbs in the study group not significantly different from those in a control group, but does not ensure the achievement of completely normal balance.
下肢负荷的对称分布和平衡是肌肉骨骼系统正常生物力学的决定因素之一。迄今为止,尚未阐明下肢轴线的矫正和长度的均衡是否能实现适当的平衡和负荷分布。本研究的目的是比较接受伊里扎洛夫方法皮质切开术的患者与健康对照组的负荷分布和平衡情况。
临床研究评估了57例行伊里扎洛夫方法皮质切开术的患者。对照组由59名健康志愿者组成。使用足底压力平台评估下肢的负荷分布和平衡情况。
在研究组中,手术肢体平均承受48.02%的负荷,而健康肢体承受51.98%。这些差异无统计学意义。治疗组和对照组肢体的平均负荷百分比无显著差异。在研究组中,重心移动路径的平均长度为145.47厘米。在对照组中,重心移动路径的平均长度为112.69厘米。在研究组中,重心面积平均为7.54平方厘米,而在对照组中为5.19平方厘米。
伊里扎洛夫方法皮质切开术使研究组下肢负荷分布值与对照组无显著差异,但不能确保实现完全正常的平衡。
