[Lower limb stump reconstruction with a functional calcaneo-plantar unit free flap. A series of 16 cases].
The main objective of surgery, once amputation is inevitable, is to preserve a functional stump. This report describes the immediate reconstruction of 16 leg stumps in children by transfer of a functional calcaneo-plantar unit. Of these, 3 were thigh and 13 were lower leg reconstructions. Amputation was performed for tumor in 4 cases, and was due to accidents in the remaining twelve. The main technical features of flap preparation are preservation of the calcaneum branch and attachment of the heel skin to the greater tuberosity of the calcaneum. One case resulted in failure due to vascular thrombosis. The other 15 cases resulted in bone consolidation after an average of 45 days, sensitive protection by 70 days, and very good trophic and protective results. The provision of good distal pressure area encourages overall development of the child. There was no morbidity at the donor site, and because there is no major muscle mass in the distal fragment, the overall risk is very low compared to that of total proximal leg replantation. The transfer of functional calcaneo-plantar tissue as a single unit is the best strategy for one-step restoration of good distal support area for the stump. All surgeons liable to perform leg amputations should be aware of this technical approach.
