Shoulder instability is a problem of a loose shoulder joint. Instability can be caused by a previous dislocation, or it may happen when the ligaments around the joint are too loose.
Shoulder Dislocation
A shoulder dislocation is an injury that occurs when the top of the arm bone (humerus) becomes disconnected from the shoulder blade (scapula). Shoulder dislocations occur after falls or other serious injuries.
Shoulder Separation
Shoulder separations are the result of a disruption of the acromioclavicular joint. This injury can cause pain and swelling of the shoulder.
Biceps Tendon Rupture
A proximal biceps tendon rupture occurs when the tendon of the biceps muscle ruptures at the shoulder joint. This may cause pain and a lump in the arm.
SLAP Lesion
The SLAP (Superior Labrum Anterior-Posterior) lesion of the shoulder is a type of labral tear. The most common cause is a fall onto an outstretched hand.
Bankart Lesion - Labral Tear
A Bankart lesion is a type of labral tear most commonly due to dislocation of the shoulder. The tear is mostly at the shoulder joint at the labrum or the protective region of the shoulder. Bankart lesions cause problems of persistent instability.
