Shoulder dislocations represent 50% of all major joint dislocations, with anterior dislocation being most common. The shoulder is an unstable ball-in-socket joint due to a shallow glenoid (shoulder socket) that only articulates with a small part of the humeral head (upper arm bone). The #shoulderjoint is the most regularly dislocated joint in the body. The shoulder can dislocate forward, backward, or downward, and completely or partially, though most occur anteriorly. Fibrous tissue that joins the bones can be stretched or torn, complicating a #jointdislocation. It usually takes a strong force, such as a blow to the #shoulder to pull the bones out of place. Extreme rotation can also pop the shoulder out of its socket. Contact sports injuries often cause a dislocated shoulder. Trauma from motor vehicle accidents and falls are also a common source of dislocation. #shoulderinjury
