Normal Anatomy of the Shoulder Joint
The shoulder is the most flexible joint in the body making it the most susceptible to instability and injury. It is a ‘ball-and-socket’ joint. A ‘ball’ at the top of the upper arm bone, humerus, fits neatly into a ‘socket’, called the glenoid, which is part of the shoulder blade, scapula.

Rotator Cuff Tear
The rotator cuff is a group of tendons in the shoulder joint that cover and provide support to the shoulder joint, enabling wider range of motion. A tear in the rotator cuff is one of the most common causes of shoulder pain in middle aged adults and older individuals. It may occur with repetitive movements while working or playing sports, during motor accidents, lifting a heavy object or a fall on an outstretched arm. As aging occurs, bone spurs may develop and can damage tendon tissue causing tears.

Various supporting structures aid in the smooth movement of the shoulder joint. The joint is held together and stabilized by a group of tendons called the rotator cuff. A fluid-filled sac called a bursa, located above the rotator cuff, helps in the frictionless movement of the shoulder. Shoulder impingement is one of the most common causes of pain in the adult shoulder.

Frozen shoulder is a painful shoulder condition that limits movement and causes stiffness in the joint. It is also called adhesive capsulitis and may progress to the state where you may find it very hard to move your arm. Frozen shoulder is more common in older adults between 40 and 60 years, and occurs more often in women than men.

The shoulder is made up of a ball and socket joint – the ball-shaped head of the upper arm bone (humerus) articulates in the socket of the glenoid cavity of the shoulder blade (scapula).Despite being the most flexible joint in the body, the bones of the shoulder are highly prone to dislocation. Repeated overhead sports and workplace activities may lead to sliding of the humerus out of the glenoid causing a dislocation.

Arthroscopy is a minimally invasive diagnostic and surgical procedure performed for joint problems. Shoulder arthroscopy is performed using a pencil-sized instrument called an Arthroscope. The arthroscope consists of a light system and camera to project images to a computer screen for your surgeon to view the surgical site. Arthroscopy is used to treat disease conditions and injuries involving the bones, cartilage, tendons, ligaments, and muscles of the shoulder joint.

Shoulder Joint Replacement
The shoulder is a highly movable body joint that allows various movements of the arm. It is a ball and socket joint, where the head of the humerus (upper arm bone) articulates with the socket of the scapula (shoulder blade) called the glenoid. The two articulating surfaces of the bones are covered with cartilage, which prevents friction between the moving bones. The cartilage is lubricated by synovial fluid. Tendons and ligaments around the shoulder joint provide strength and stability to the joint.

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. It is one of the most common causes of shoulder pain in middle aged adults and older individuals. It may occur with repeated use of arm for overhead activities, while playing sports or during motor accidents. Rotator cuff tear causes severe pain, weakness of the arm, and crackling sensation on moving shoulder in certain positions. There may be stiffness, swelling, loss of movements, and tenderness in the front of the shoulder.
