Distortion of the axis and shortening of the limbs result in multiple musculoskeletal pathologies. Rotation disorders should also be included among the disorders of the axis of the lower limb. In the case of rotational distortion, only derotation osteotomy can effectively correct torsion-associated deformations. Rotational distortion correction is accompanied by translational displacement and torsion, which results in more complex biomechanics. Using the pedobarographic platform, it is possible to evaluate static and dynamic posture and gait, percentage of body weight distribution on the lower limbs, and balance. Physiological gait and distribution of weight on the lower extremities are symmetrical. Balance is one of the determinants of proper biomechanics of the musculoskeletal system. An important aspect of treatment evaluation is pedobarographic assessment of balance and body weight distribution on the lower extremities ratio. The aim of this work was to evaluate the pedobarographic assessment of body weight distribution on the lower limbs and balance in patients with derotation corticotomies using the Ilizarov method. The study examined a group of 56 patients, who underwent derotation corticotomy using the Illizarov method between 1996 and 2012 at the Clinic of Orthopaedics and Traumatology of the Musculoskeletal System in Wrocław. The control group consisted of 54 patients, who were treated with correctional derotation-free corticotomy using the Ilizarov. Distribution of body weight on the lower limbs and balance were assessed with the pedobarographic platform. Following derotation corticotomy, the amount of body weight placed on the operated limb by subjects from the study group averaged 47.81%, 52.19% in the case of the healthy limb. These differences were not statistically significant. The difference between the average percentage of body weight placed on the diseased and healthy limb in the study group and the controls were not found to be statistically significant. There were no statistical differences in the average length of the gravity line or in the average surface area of the center of gravity position between the study and control groups. Balanced distribution of body weight on the lower limbs was achieved following derotation corticotomies using the Ilizarov method. Derotation corticotomies performed with the Ilizarov method allow for achieving normalization of body weight distribution on the lower limbs and balance, with values similar to those resulting from Ilizarov method derotation-free osteotomy.
轴线扭曲和肢体缩短会导致多种肌肉骨骼疾病。旋转障碍也应归入下肢轴线紊乱范畴。对于旋转性扭曲，只有去旋转截骨术才能有效纠正与扭转相关的畸形。旋转性扭曲的矫正伴随着平移位移和扭转，这使得生物力学情况更为复杂。使用足印测量平台，可以评估静态和动态姿势及步态、下肢的体重分布百分比以及平衡情况。生理步态和下肢的体重分布是对称的。平衡是肌肉骨骼系统正常生物力学的决定因素之一。治疗评估的一个重要方面是通过足印测量法评估平衡以及下肢体重分布比例。本研究的目的是评估采用伊里扎洛夫方法进行去旋转皮质切开术的患者下肢体重分布及平衡的足印测量评估情况。该研究调查了一组56例患者，他们于1996年至2012年期间在弗罗茨瓦夫肌肉骨骼系统矫形与创伤诊所接受了使用伊里扎洛夫方法的去旋转皮质切开术。对照组由54例接受使用伊里扎洛夫方法进行无旋转矫正皮质切开术治疗的患者组成。使用足印测量平台评估下肢的体重分布和平衡情况。去旋转皮质切开术后，研究组受试者患侧肢体承受的体重平均为47.81%，健侧为52.19%。这些差异无统计学意义。研究组和对照组患侧与健侧下肢体重平均百分比差异无统计学意义。研究组和对照组在重力线平均长度或重心位置平均表面积方面均无统计学差异。采用伊里扎洛夫方法进行去旋转皮质切开术后，下肢实现了体重的均衡分布。采用伊里扎洛夫方法进行的去旋转皮质切开术能够使下肢体重分布和平衡恢复正常，其数值与使用伊里扎洛夫方法进行的无旋转截骨术相近。
