Shoulder Dislocation

The shoulder joint is also referred to as a ball and socket joint due to 3-dimensional movement of the arm, as a result of the unique arrangement and alignment of scapula, humerus and clavicle. The shoulder joint is supported by a number of ligaments, muscles and connective tissue components to provide the strength and stability during joint motion. However, sudden and severe impact of force at the level of shoulder may lead to the displacement of one or more bones of the shoulder joint, leading to shoulder dislocation.

What is Shoulder Dislocation?

A Shoulder Dislocation occurs when the ball and socket joint of the shoulder are separated from each other, usually from a fall or a blow to the shoulder. This can lead to injury to the muscles, tendons and tissues around the joint, as well as possibly tearing the cartilage protecting the bone.

A Partial Shoulder Dislocation occurs when the socket at the humerus is only partly out of the socket joint at the shoulder.
