Reconstruction of achilles tendon and calcaneus defects with skin-aponeurosis-bone composite free tissue from the groin region

Eight patients had reconstructive surgery for soft-tissue, associated Achilles tendon, and calcaneous defects on the posterior aspect of the ankle. In group A, those patients with skin, soft-tissue, and Achilles tendon loss were treated with free groin flaps that included sheets of the external oblique aponeurosis based on the superficial circumflex iliac vessel. The groin flap provided skin coverage, and the aponeurosis was rolled to form a tendon-like structure to replace the Achilles tendon. In group B, those patients with an additional calcaneus bone loss were treated with free iliac osteocutaneous flaps, together with the external oblique aponeurosis based on the deep circumflex iliac vessel. The iliac bone was then utilized to reconstruct the calcaneus defect. All composite free tissue transfers were successful, except in two group B patients who suffered partial skin loss. The advantages of this technique are (1) a single, one-stage procedure, (2) faster wound healing with fewer adhesions of the reconstructed Achilles tendon, and (3) good cosmesis and minimal morbidity at the donor site.
