Anatomic study of the medial pedis composite flaps with saphenous nerve and tendon and its application

Objective To investigate the anatomy of the medial pedis composite flaps with suphenous nerve and tendon and its application in the repair of tendo caleaneus and adjacent defects. Methods 10 cadavers (20 sides) were observed. The origin, course, size and the distribution of the medial plantar artery were studied. 12 cases with tendo calcanens and adjacent defeets were reconstructed with the medial pedis composite flaps with suphenous nerve. Donor site defects were covered with free skin graft. Results The medial plantar artery gives off deep branch[diameter (1.5±0.3)mm]and superficial branch[diameter (1.0±0.2)mm]. In 18 sides, the deep branches give off the medial branches and lateral branches. While in 2 sides, the superficial branches give off the medial branches and lateral branches with no big branches from the deep branches. There are branches of saphenous nerve and medial dorsal cutaneous nerve in the flap. All the flaps were survived. 8 cases were followed up for one months to one years. Good color, texture and function of the flaps were achieved. Conclusions The medial pedis composite flaps with suphenons nerve can repair tendo calcanens and adjacent defects. It is a easy and safe procedure with reliable anatomy and good results. Key words: Foot;  Surgical flap;  The medial plantar artery;  Saphenons nerve
