A common form of shoulder dislocation is anterior dislocation, which is a dislocation towards the front and bottom of the shoulder joint. The anterior aspect of the shoulder capsule is generally weak, and it is easy for the shoulder joint to dislocate anteriorly when subjected to external forces. In anterior dislocation, the joint capsule is in a relatively tense state in front of and below the shoulder, and the head of the humerus is on top of the capsule in front of and below the joint capsule. Anterior dislocation of the shoulder joint is usually characterized by an empty glenoid, square shoulder deformity, limited arm flexion and extension, and swelling and pain in the shoulder joint. The shoulder joint is one of the joints with the largest range of motion in the human body, and because the glenoid of the shoulder joint is shallow and flat, it is easy for the head of the humerus to detach from the glenoid when traumatized, resulting in anterior dislocation of the shoulder joint. For example, anterior dislocation of the shoulder joint can be caused by a fall from a height, a traffic accident, or a fall. When the shoulder joint is dislocated, it is recommended to go to the hospital in time for treatment and have it reset by an orthopedic surgeon.
