The Intramuscular Neurovascular Anatomy of the Latissimus Dorsi Muscle

Abstract
A consistent proximal branching of the neurovascular supply to the latissimus dorsi muscle is described in humans. This anatomical feature makes possible splitting the muscle and overlying cutaneous territory into independent branched musculocutaneous units. A parallel study of neurovascular anatomy in dogs suggests that this animal is an appropriate model for testing and developing clinical applications the split latissimus dorsi flap.
