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.

Shoulder impingement is also called as 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, and while playing sports such as tennis, baseball, swimming and weight lifting.

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 is a condition of painful shoulder with limited movement because of pain and inflammation. It is also referred as adhesive capsulitis and may progress to the state where an individual may feel very hard to move the shoulder.

Shoulder joint replacements are usually done to relieve pain and when all non-operative treatments to relieve pain have failed.

Shoulder instability is a chronic condition that causes frequent dislocations of the shoulder joint. A dislocation occurs when the end 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 referred

The labrum is a “cuff” of cartilage that extends the size of the shoulder socket (glenoid) holding the arm (humerus) in place. It is not to be confused with the “rotator cuff,” which is a composite structure of muscles and tendons.

AC Joint Separation
The AC joint is the articulation between the medial end of the acromion and the distal (lateral) end of the clavicle. The AC joint is located above

Loose bodies are small loose fragments of cartilage or a bone that float around the joint. The loose bodies can cause pain, swelling, locking and catching of the joint.

Pectoralis Tendon Tear
The pectoralis muscle is a large muscle that is located in front of your chest and helps to move your shoulder forwards and across your chest. The pectoralis muscle is divided into the pectoralis major and the pectoralis minor.

Biceps Tendon Tear
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.

Triceps Tendon Tear
The triceps is the large muscle in the back of the elbow that serves to straighten your elbow. Ruptures involving the distal triceps tendon are relatively uncommon and normally results from a sudden injury such as a fall on an outstretched hand
