How does the Shoulder joint work?
Major injury to the tendons that stabilize the shoulder can result in a rotator cuff tear. Minimally invasive arthroscopic techniques can be used to repair the rotator cuff.

Arthroscopic stabilization is a surgical procedure to treat chronic instability of shoulder joint. The shoulder is the most flexible joint in our body making it more susceptible to instability and injury. Shoulder instability occurs when the head of the humerus (upper arm bone) dislocates from the glenoid (socket) as a result of a sudden injury or overuse. The repeated dislocation of the humerus out of its socket is called chronic shoulder instability. A tear in the labrum or rotator cuff and a ligament tear in the front of the shoulder (a Bankart lesion) may lead to repeated shoulder dislocations. Shoulder instability is often treated by the technique called stabilization which can be performed arthroscopically.

Frozen shoulder, or adhesive capsulitis, is a painful condition with limited movement because inflammation.

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.

Shoulder impingement is also called swimmer’s shoulder, tennis shoulder, or rotator cuff tendinitis. It is the condition of inflammation of the tendons of the shoulder joint caused by motor vehicle accidents, trauma, or sports such as tennis, baseball, swimming and weight lifting.

Shoulder instability is a chronic condition that causes frequent dislocations of the shoulder joint. A dislocation occurs when the head of the humerus (the ball portion) partially or completely dislocates from the glenoid (the socket portion) of the shoulder. A partial dislocation is referred as subluxation, whereas the complete separation is called dislocation.

In a shoulder replacement, damaged portions of the humerus (upper arm bone) and scapula (shoulder blade) are removed and replaced with artificial components in order to reduce pain and increase mobility. The shoulder is a “ball and socket” joint, and depending on the indication for a shoulder replacement, both components of the joint do not always need to be replaced.

Reverse total shoulder replacement, is an advanced surgical technique specifically designed for rotator cuff tear arthropathy, a condition where the patient suffers from both shoulder arthritis and a rotator cuff tear.
