The aim of this study was to analyze gait function and muscular strength on donor site after harvesting of a vascularized fibula osteoseptocutaneous flap. Nine patients with a mean follow-up of 33 months (range, 7-59) and a mean resection length of the middle portion of the fibula of 18.0 cm (range, 14.0-23.0) underwent an instrumented three-dimensional gait analysis to evaluate gait function. Furthermore, CYBEX II extremity system was used for muscular strength measurements. Subjective muscle strength measurements were performed according to Kendall et al. and were classified according to the British Medical Research Council. Intraindividual comparison between the operated and the nonoperated leg revealed no significant differences for gait function parameters (cadence, velocity, and stride length, P > 1.00) and for muscular strength measurements for flexion (knee: P = 0.93, ankle: P = 0.54) and extension (knee: P = 0.97, ankle: P= 0.21), respectively. In conclusion, intraindividual comparison of the operated and nonoperated sides after harvesting of the middle portion of the fibula for gaining a free fibula osteoseptocutaneous flap has no adverse affect on gait function or muscular flexion and extension strength on donor site at a mean follow-up of 33 months.
本研究旨在分析游离腓骨皮瓣切取术后供区的步态功能和肌肉力量。9 例患者平均随访 33 个月（范围 7-59 个月），腓骨中段平均切除长度为 18.0cm（范围 14.0-23.0cm），接受了仪器化三维步态分析以评估步态功能。此外，还使用了 Cybex II 肢体系统进行肌肉力量测量。根据 Kendall 等人的方法进行了主观肌肉力量测量，并根据英国医学研究委员会进行了分类。对手术侧和非手术侧进行的个体内比较显示，步态功能参数（步频、速度和步长）和肌肉力量测量（膝关节屈伸：P=0.93，踝关节屈伸：P=0.54）以及膝关节屈伸：P=0.97，踝关节屈伸：P=0.21）均无显著差异。总之，在腓骨中段切取游离腓骨皮瓣后，对手术侧和非手术侧进行个体内比较，在平均 33 个月的随访中，不会对供区的步态功能或肌肉屈伸力量产生不利影响。
