Reconstruction of the lateral malleolus and calcaneus region using free thoracodorsal artery perforator flaps.
Reconstruction of the lateral malleolus or calcaneus region is challenging because of poor vascularity, minimal presence of soft tissue, and difficulties with flap positioning during and after the operation. In many cases, local flaps are limited in terms of size, durability, and vascularity. Free tissue transfer can be useful for complicated wounds. We report here on the results of the reconstruction in this region using free thoracodorsal artery perforator flaps. Between October 2010 and October 2013, 16 cases of lateral malleolus or calcaneus defects were reconstructed using free thoracodorsal artery perforator flaps. The defects varied from 2 × 5 cm(2) to 12 × 16 cm(2), and the flaps from 3 × 5 cm(2) to 10 × 15 cm(2). Two cases were reconstructed using chimeric-pattern flaps. Only the superficial adipose layers were harvested for all the flaps, without further thinning or debulking process. Five cases with complications occurred, including three cases of partial necrosis of the flap and two cases of venous congestion caused by thrombosis and compression of the venous pedicle, and one flap was totally lost. The mean follow-up duration was 11.8 months. All the patients were able to wear shoes. All but one were able to walk. The thoracodorsal artery perforator flap can be made super-thin, allowing patients to wear shoes, and it can be harvested in a chimeric-pattern for complex defects. Therefore, it may represent a viable alternative choice for the reconstruction of the lateral malleolus and calcaneus region.
