Lateral arm flap

Abstract

The lateral arm flap is a reliable flap with a constant moderate diameter size pedicle which length ranges from 4-8 cm according to the design of the flap. The flap is bound by the insertion of the deltoid muscle proximally and the lateral epicondyle distally. The lateral arm flap could be raised as a fascial, fasciocutaneous, or osteocutaneous flap with or without sensory innervation. It can be used as a direct, distant or a free flap to cover various regional defects of the upper extremity and distant defects especially the head and neck region with minimal donor site morbidity.
