The axillary arch is a variant of the latissimus dorsi muscle in humans. It is found as a slip of muscle or fascia extending between the latissimus dorsi muscle and the pectoralis major. There is considerable variation in the exact position of its origin and insertions as well as its blood and nerve supply.[1] The arch may occur on one or both sides of the body.[2] A meta-analysis revealed that the axillary arch had an overall prevalence of 5.3% of limbs.[3]
The arch is considered to have no functional significance, although this is challenged by some authors.[2][4] It plays a role in entrapment of nearby structures and may alter local anatomy if a dissection of the local area is needed during surgery. The arch appears to arise from the panniculus carnosus, a structure found in most non-primate mammals, and has similarities with muscles found in many animals. The axillary arch has several other names including Langer's axillary arch, the muscle of Langer, axillopectoral muscle, Achselbogen and pectorodorsalis muscle.[5]
