Functional and social long-term results after free tissue transfer to the lower extremity

We report the long-term social and functional results in 53 patients receiving free tissue transfer after trauma to the lower extremity. The results are compared with those of a matched group of patients receiving primary amputation. The microsurgically treated patients had significantly more complaints over pain during walk (p = 0.02) and edema (p < 0.00005). Regarding social results, no significant differences between the two groups were found. Time until surgery, infection, or bone defect before free flap surgery did not alter the overall results significantly. It is concluded that the long-term functional and social results after free tissue transfer are almost the same as those achieved after simple amputation. Because the median time until free flap surgery in this series was 158 days, early limb-saving procedures could possibly improve the long-term results.
