Shoulder Subluxation

Shoulder Subluxation

Shoulder subluxation refers to the partial dislocation - humerus (upper arm bone) and glenoid cavity are partially disjointed. The common types are anterior subluxation and posterior subluxation.

The common symptoms include: extreme shoulder pain, swelling, bruising, weakness, numbness, shoulder laxity, shoulder instability. Shoulder subluxation often requires immediate medical treatment.

Shoulder subluxation occurs, often due to the weak rotator cuff muscles or lax tendons. Some athletes, e.g. wrestlers, football players, basketball players, are prone to shoulder subluxation. Arthritis and muscle degeneration may also lead to shoulder subluxation.
