Composite neuromusculo-fasciocutaneous triceps brachii free flap for complex foot reconstructive surgery.

Since it was first described by Song in 1982, then by Katsaros in 1984, the lateral arm flap has become a workhorse technique for upper limb reconstruction. Herein we describe a clinical case of complex foot defect and bring up the possibility of using a composite neuromusculo-fasciocutaneous lateral arm/triceps free flap for its reconstruction. A 19-year-old male nonsmoker suffered ballistic trauma to his right foot with open multifragment Gustilo-IIIb fractures of the first to fifth metatarsal bones. Two weeks after debridement and V.A.C.™ therapy performed in another hospital, we decided to reconstruct the remaining defect with a neuromusculo-fasciocutaneous medial triceps/lateral arm free flap anastomosed with the anterior tibial pedicle. The posterior brachial cutaneous nerve was sutured to a sensory branch of the superficial fibular nerve. The advantages and drawbacks of this technique are discussed and other options for this type of complex foot reconstruction are reviewed. After 3 years' follow-up, the metatarsal bones were consolidated without residual defect or chronic infection. The foot had sensation with full mobility and no pain. At the donor site, there was no complaint of scarring. Elbow extension/flexion was 0-0-130. Wrist extension/flexion was 60-0-60 and there was no extension deficit of the metacarpophalangeal joints. The composite neuromusculo-fasciocutaneous triceps brachii free flap was an excellent option for this complex foot defect. The choice of this reconstructive procedure among other options was made during our reconstruction board meeting while taking the patient's specific condition and our own experiences into account.
