Classification of the vascular anatomy of muscles: experimental and clinical correlation.

Five patterns of muscle circulation, based on studies of the vascular anatomy of muscle, are described. Clinical and experimental correlation of this classification is determined by the predictive value of the vascular pattern of each muscle currently useful in reconstructive surgery in regard to the following parameters: arc of rotation, skin territory, distally based flaps, microvascular composite tissue transplantation, and design of muscle-delay experimental models. This classification is designed to assist the surgeon both in choice and design of the muscle and musculocutaneous flap for its use in reconstructive surgery.
