Microvascular free muscle reconstruction of a large plantar defect.

Large plantar defects present a difficult problem in reconstructive surgery. Skin grafts are not durable and most distant flaps are too bulky to allow for ambulation in conventional footwear. Free muscle transfer with skin graft may represent a modality to provide a contoured and durable reconstruction for large plantar defects when local tissue is not available. This study presents a case of sole of foot and distal heel reconstruction with a free microvascular latissimus muscle transfer. The transfer was contoured to fit the defect and then covered with a split-thickness skin graft. Three months following surgery, the patient was walking without assistive devices and using conventional footwear. Now, two and one-half years after surgery, he is employed full-time in a job that entails walking, and has never experienced a tissue breakdown.
