A dislocated shoulder is an injury that occurs when the upper arm bone becomes displaced from the cup-shaped shoulder socket, according to Mayo Clinic. The shoulder is vulnerable to dislocation from falls and trauma because of its high mobility.
Shoulder dislocation is common in sporting activities such as football, rugby, soccer, skiing and hockey, notes WebMD. A dislocated shoulder requires prompt medical attention. Patients typically regain full shoulder function after a few weeks. However, in some cases the injury causes the shoulder joint to become unstable and susceptible to recurrent dislocations, states Mayo Clinic.
To treat shoulder dislocation, a doctor physically manipulates the shoulder to restore it, suggests wearing a sling for several weeks or performs surgery, says WebMD. The doctor also prescribes medication for pain and swelling.
