Our shoulders have a range of motion that no other part of the body has, and that flexibility allows us to perform myriad activities. As a result, the shoulders are more likely to suffer injuries.
Some of the common ones are dislocation, sprain, separation and fractures.
* Dislocation: When the arm is jerked backward or pulled sharply, the head of the humerus (the bone of the upper arm, or forelimb) may come out of the shoulder socket. A dislocated shoulder is painful and prevents movement of the shoulder. Numbness, swelling and bruising might also occur.
