Abstract
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.
