The purpose of this study was to demonstrate gait disturbance after fibular flap transfer using preoperative and postoperative gait analysis. The gait performance of 20 patients was assessed at the Laboratory for Biomechanics, Seoul National University Hospital. Kinematic and kinetic data were collected simultaneously while walking on a 25-m walkway. One month postoperatively, a significant (p<0.05) decrease in the time-distance parameter as well as a significant (p<0.05) decrease in the peak plantarflexion and dynamic range was seen. Only peak plantarflexion in swing was significantly (p<0.05) decreased until 3 months postoperatively. On the basis of the gait analysis results, it was concluded that normalization of the patients' gaits would be expected within 3 months after the operation. There were no permanent pathological changes in the donor site.
本研究的目的是通过术前和术后步态分析来证明腓骨瓣转移术后的步态障碍。在首尔国立大学医院生物力学实验室对20例患者的步态表现进行了评估。在25米的步行道上行走时同时收集运动学和动力学数据。术后1个月，时间-距离参数显著降低（p<0.05），同时跖屈峰值和动态范围也显著降低（p<0.05）。直到术后3个月，仅摆动期的跖屈峰值显著降低（p<0.05）。根据步态分析结果，得出结论，患者的步态有望在术后3个月内恢复正常。供区无永久性病理改变。
