Rhomboid major

Medically reviewed by Healthline Medical Team on March 20, 2015

The rhomboid major muscle is located in the back region and helps keep the scapula, or shoulder blade, attached to the ribcage. It also rotates the scapula and retracts it towards the spinal column. It has origination points in the second, third, fourth, and fifth thoracic vertebrae (T2 though T5). The rhomboid major muscle receives oxygenated blood from the dorsal scapular artery, which arises from the subclavian artery. The dorsal scapular nerve provides innervation and a connection to the spinal column. If the rhomboid major is damaged or torn, the scapula becomes partially debilitated; this will limit the range of motion in the upper extremities. Treatment for rhomboid major injuries requires surgery and post-surgical physical therapy, which includes stretching and muscular endurance activities.
