Normal Anatomy of the Shoulder Joint

How does the Shoulder joint work?

Rotator Cuff Tear

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 Labral Tear

The shoulder joint is a “ball and socket” joint that enables the smooth gliding and thereby the movements of arms. However it is inherently unstable because of the shallow socket. A soft rim of cartilage, the labrum lines the socket and deepens it so that it accommodates the head of the upper arm bone better.

Acromioclavicular Joint Dislocation

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.

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. A ‘ball’ at the top of the upper arm bone, humerus, fits neatly into a ‘socket’, the glenoid, which is part of the shoulder blade, scapula.

Shoulder Instability

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 as dislocation.

Shoulder Impingement

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

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.

Arthroscopic Shoulder Instability Repairs

The shoulder is the most flexible joint in the body. It allows for a range of movements of the hands, however makes it the most unstable joint of the body. It is a ball and socket joint where the head of the upper arm bone (humerus) articulates to the shallow cavity in the shoulder blade (glenoid).

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.

Shoulder Joint Replacement

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

SLAP Repair

Your shoulder joint is a ball and socket joint made up of the upper arm bone, the shoulder blade and the collarbone. The head of the upper arm bone fits into the socket of the shoulder joint known as the glenoid cavity. The outer edge of the glenoid is surrounded by a strong fibrous tissue called the labrum.
