Functional free latissimus dorsi muscle flap to the proximal lower extremity.

Surgical treatment of lower extremity sarcoma often requires complete resection of muscle compartments resulting in disabling functional loss. Free muscle transfer has been used to restore function of the face and upper extremities, but few reports exist describing functional restoration of a lower extremity. A case report of a 21-year-old man requiring complete resection of the quadriceps musculature with successful functional reconstruction using a free latissimus dorsi muscle flap is described.
