What are the 6 muscles used in scapular stabilization?
The extrinsic muscles include the triceps, biceps, and deltoid. The third group of muscles includes the levator scapulae, trapezius, rhomboids, and serratus anterior. These muscles are responsible for rotational movements and stabilization of the scapula.
How is the scapula stabilized?
The serratus anterior is an important scapular stabilizing muscle. It originates from the first eight ribs and courses along the rib cage to insert along the anterior medial aspect of the scapula.
How do you fix the scapula instability?
To correct severe instability, open surgery is often necessary. An incision is made over the shoulder and the muscles are moved to gain access to the joint capsule, ligaments and labrum (Figure 6).
