| What is Instability of the Shoulder? What does it mean to have a "loose" shoulder?  Most commonly after an anterior dislocation. Joint does not have enough stability. The shoulder has more movement than any other joint in the body. Athletes such as pitchers need that increase in mobility to be great pitchers, but must have the stability also in the core of the shoulder. The end bone of the upper arm (humeral head) fits into the body (at the glenoid labrum). It is like a golf ball fitting on a golf tee, with the glenoid labrum being 4 times smaller than the humeral head. There are ligaments (connect muscle to bone) and other aspects (capsule, negative intra-articular pressure, adhesion, and proprioceptors) that contribute to keeping humeral head connected. The muscles provide stability when the arm is moving, or called dynamic stability. The muscles around the shoulder blade (scapular stabilizers) are critical and provide a stable base. Everyone needs proximal stability for distal mobility. We call it the "Scapular Core", similar to how you need a strong core in the mid section. Instability was classified by Neer as Traumatic or Acquired/Atraumatic. Traumatic: Most common is anterior dislocation where the head of the humerus comes out at the front of the shoulder Atraumatic: Happens over time, usually with overuse first, microtrauma, laxity, subluxation, impingement (see "What is Shoulder Impingement?"), rotator cuff injury (see "What is the Rotator Cuff?")
