Reappraisal of island modifications of lateral calcaneal artery skin flap

Reconstruction of soft-tissue defects of the calcaneal region and the heel is very demanding and necessitates, as a rule, a sensate and thin flap. The ideal characteristics of a sensate and thin layer of flap should be combined with a reliable blood supply and minimal morbidity at the donor site. The authors report an updated review of their experience with the use of island modifications of the lateral calcaneal artery skin flap-the lateral calcaneal island flap, the lateral calcaneal V-Y advancement flap, and the bilobed-shaped lateral calcaneal island advancement flap-for the reconstruction of small and medium-sized tissue defects over the exposed calcaneal tendons and calcaneal bones of 18 patients. All of the procedures were performed under spinal or epidural anesthesia. There were no problems associated with flap viability, but the authors have seen necrosis of undermined skin between the lateral malleolus and calcaneal tendon in two cases and a partial loss of skin graft in one case. In this article, the authors discuss some advantages and disadvantages of the use of a lateral calcaneal island flap and its modifications.
