In some cases, arthroscopic surgery is not enough to fix the injured shoulder. When the shoulder dislocates too many times and is worn down, the ball and socket are not lined up correctly. The socket is worn down and the ball will never sit in it the same. After many dislocations the shoulder bones will begin to wear down and chip away.
A SLAP tear or SLAP lesion is an injury to the superior glenoid labrum (fibrocartilaginous rim attached around the margin of the glenoid cavity in the shoulder blade) that initiates in the back of the labrum and stretches toward the front into the attachment point of the long head of the biceps tendon.
The glenoid cartilage underneath the labrum in the glenohumeral (GH) joint is disrupted by glenolabral articular disruption. [5] The articulation of the humeral head inside the glenoid fossa of the scapula forms the GH joint itself, which is a synovial ball and socket joint.
Once full passive motion is regained (at usually about four to four and a half months after surgery) strengthening exercises are the focus. The strengthening focuses on the rotator cuff and the upper back/scapular stabilizers. Typically at about six months after surgery, most have made a majority of their expected gains.

Lightbulb sign indicative of posterior shoulder dislocation shown on the left. On the right, the same shoulder after reduction. Posterior dislocations are uncommon, and are typically due to the muscle contraction from electric shock or seizure. [6] They may be caused by strength imbalance of the rotator cuff muscles.
After removing the strap and sling, the doctor will prescribe exercises to strengthen the shoulder and restore movement. Surgery is occasionally needed for certain clavicle fractures, especially for disunions. [citation needed] Fracture of the neck of the humerus is usually treated with a sling or shoulder immobilizer. If the bones are out of ...
Arthroscopy is commonly used for treatment of diseases of the shoulder including subacromial impingement, acromioclavicular osteoarthritis, rotator cuff tears, frozen shoulder (adhesive capsulitis), chronic tendonitis, removal of loose bodies and partial tears of the long biceps tendon, SLAP lesions and shoulder instability. The most common ...
A SLAP lesion (superior labrum, anterior to posterior) is a tear where the glenoid labrum meets the tendon of the long head of the biceps muscle. Symptoms include increased pain with overhead activity, popping or grinding, loss of strength, and trouble localizing a specific point of pain. [3]
