The shoulder joint is the most mobile joint of the body. It has the flexibility to turn in many directions. But this advantage can be the very disadvantage that makes the shoulder prone to dislocation. If your shoulder is sprained upward and backward, chances are it will dislocate out of its socket. Shoulder dislocation is both painful and incapacitating. A seemingly simple fall or a collision with another person or object can result in shoulder dislocation. Shoulder dislocation is prevalent in contact sports.
Shoulder can dislocate forward, backward or downward. Anterior instability is the most common type of shoulder dislocation. It happens when the shoulder slips forward. It generally happens when the arm is put in a throwing motion. Shoulder dislocation can be either partial or complete.
Partial Dislocation (Subluxation) – The head of the upper arm is partially out of the shoulder socket.
