The posterior end lies at the level of the sixth rib. The scapula commonly referred to as the shoulder blade is the bone that sits above the rib cage in the upper back. It creates the shoulder joint where it meets with the head of the humerusthe bone of the upper arm.

It is a sturdy flat triangular bone. The scapula provides attachment to several groups of muscles. The intrinsic muscles of the scapula include the rotator cuff muscles teres major subscapularis teres minor and infraspinatus.

The scapula better known as the shoulder blade is a triangular bone that serves as a joining force between the clavicle and the humerusThis bone is located posteriorly on the back half of the body. The scapula plays an important role in stabilizing the other bones involved in the rhythm of shoulder motion.
