What parts of my shoulder joint stabilize it?

Dr. Kristofer J. Jones, MD
Orthopedic Surgeon

There are two types of stabilizing forces in the shoulder: the dynamic stabilizers, which primarily include the muscles that surround the shoulder joint, including the rotator cuff and scapular stabilizers, and the static stabilizers such as the glenohumeral ligaments and labrum, which surrounds the socket (glenoid). The glenohumeral ligaments are located within the shoulder capsule that surrounds the entire joint. The labrum is a fibrocartilaginous structure, which is a biologic material similar to the meniscus in the knee; it surrounds the glenoid socket in order to deepen it and provide stability to the shoulder.

A shoulder's joint stability comes from the muscle strength and tendon structures around it.
