What is Viscosupplementation for Shoulder Arthritis?
Viscosupplementation is a minimally invasive procedure that involves the injection of a hyaluronic acid preparation into the shoulder to treat arthritis. Hyaluronic acid is a naturally occurring substance which is present in the joint fluid that acts as a shock absorber and enhances lubrication.
Indications for Viscosupplementation for Shoulder Arthritis
Viscosupplementation is mainly indicated to treat pain and swelling in the shoulder joint caused due to arthritis that is not relieved by other conservative measures such as over-the-counter pain medications or corticosteroid injections.
Anatomy of Shoulder
The shoulder is a very flexible ball and socket joint that consists of 3 bones, the collarbone (clavicle), the upper arm bone (humerus), and the shoulder blade (scapula). An irregular shallow cavity called the glenoid cavity present in the scapula forms the socket for the head of the humerus to fit in. The scapula is a flat triangular-shaped bone that serves as a site of attachment for the shoulder muscles providing stability to the joint. The clavicle bone connects the scapula to the breastbone.
