Rotator cuff tears are one of the most common causes of shoulder pain and disability in the adult patient. Between 1998 and 2004, over 5 million office visits were attributable to shoulder pain and in 2008 alone, nearly 2 million people saw their doctor due to a torn rotator cuff.

Impingement, bursitis, tendonitis, are all different words for the same underlying problem. The subacromial space is the space below the end of the shoulder blade (acromion) and top of the humeral head.

Shoulder arthroscopy is a surgical procedure in which an arthroscope is inserted into the shoulder joint. The benefits of arthroscopy are smaller incisions, faster healing, a more rapid recovery, and less scarring. Arthroscopic surgical procedures are often performed on an outpatient basis and the patient is able to return home on the same day.

Frozen shoulder, or adhesive capsulitis, is an inflammatory disorder of the shoulder that causes fibrosis (scarring) of the joint capsule leading to pain and loss of motion. The capsule of the shoulder is normally a very thin, elastic layer of tissue that forms the wall of the joint and assists with shoulder stability.

The shoulder has the greatest motion of any joint in our body. The price it pays for this great mobility is that it is also the joint most at risk of dislocation. There are different degrees of instability.

Rotator Cuff Arthropathy
Motion thru the glenohumeral joint (ball and socket) is accomplished by a fine equilibrium created by the muscles that surround the shoulder. This equilibrium is largely created by the deltoid and rotator cuff.

The biceps muscle, located in the front of the upper arm allows you to bend the elbow and rotate the arm. Biceps tendons attach the biceps muscle to the bones in the shoulder and in the elbow.

Acromioclavicular (AC) joint arthritis
Acromioclavicular (AC) joint arthritis is a condition that develops when the cartilage cushioning the AC joint in the shoulder begins to wear out. The shoulder is a ‘ball-and-socket’ joint.

Calcific cuff tendinopathy is a problem with the shoulder’s tendons and muscles. This condition occurs due to the formation of calcium deposits in the tendons (tissue which attaches muscle to bone) of the rotator cuff (group of muscles and tendons stabilizing the shoulder).

The clavicle or the collarbone is the bone that connects your sternum or breastbone to your shoulder.

Playing more overhead sports activities and repeated use of shoulder at workplace may lead to sliding of the upper arm bone, the ball portion, from the glenoid–the socket portion of the shoulder.

Bicipital tendonitis is the inflammation of the biceps tendon, the tissue that connects muscle to bone in your upper arm, causing pain in the upper arm and shoulder.

Total Shoulder Replacement
Advances in shoulder replacement surgery over the past two decade have resulted in highly successful outcomes for patients suffering from shoulder arthritis.

Reverse Shoulder Replacement
The reverse shoulder replacement is a remarkable device that has truly revolutionized shoulder replacement surgery. Prior to its development, patients suffering from shoulder arthritis with a large rotator cuff tear or those with simply a large irreparable tear without arthritis had very few treatment options.

Arthroscopic Rotator Cuff Repair
Rotator cuff is the group of tendons in the shoulder joint providing support and enabling wider range of motion. Major injury to these tendons may result in tear of these tendons and the condition is called as rotator cuff tear.

Labrum repair is a surgical technique recommended for treating labrum tear. Labrum is a triangular, fibrous, rigid cartilage structure lining the ball-and-socket joint of the shoulder.
