The Dual Muscle Flap Based on the Thoraco-Dorsal Vascular System for Limb Reconstruction

ABSTRACT

The dual muscle flap (Latissimus dorsi+ Serratus anterior muscle) based on the thoraco-dorsal vascular system for limb reconstruction has been infrequently reported. We have used this flap as a free flap for limb reconstruction in four patients (3 cases in lower linb, 1 in upper limb). A Latissmusi dorsi muscle or musculocutaneous flap and Serratus anterior muscle flap were used and all cases healed satisfactorily. The indications for this flap are to resurface two separate defects simultaneously or to resurface very large defects. It has the advantage of requiring anastomosis of one vascular pedicle only. This flap is particularly suitable for resurfacing defects wider than their length, in relation to the long axis of the limb.
