Shoulder injuries can occur in any part of the shoulder. It can occur in the three bones that include the collarbone, the shoulder blade and the upper arm bone. If the shoulder socket is smaller than the ball of the upper arm, shoulder instability can also occur. Shoulder injuries can include sprains, strains, dislocations, separations, fractures and torn rotator cuffs. If a shoulder injury is ignored or not adequately treated, it can result in several complications.
Arthritis
MayoClinic.com reports that arthritis can develop as a complication of a shoulder injury. If the individual has a separated shoulder, treatment can usually cure it. If not, the injury raises the risk of an individual developing arthritis.
Recurrence of Injuries
National Institute of Arthritis and Musculoskeletal and Skin Diseases states that recurrence of injuries is a complication of shoulder injuries. This is especially true for those who have dislocated their shoulder and are young and active. Because the ligaments present in the affected joint might have been stretched or torn during the dislocation, the shoulder is more susceptible to dislocation again. If the dislocation occurs too often or is severe, the surrounding tissues or nerves can be affected. The patient might require surgery so the stretched ligaments can be mended or the torn ones can be reattached.
Rotator Cuff Tear
According to the National Institute of Arthritis and Musculoskeletal and Skin Diseases, an individual who has undergone surgery to repair a rotator cuff tear can suffer from another tear. Jobs where excessive lifting of heavy objects is required can place strain on a repaired rotator cuff. With age, the tendons can become weak and degenerate. This can cause complete tears in both the muscles and the tendons. If the individual gets continued tears in the rotator cuff, partial or total shoulder replacement might be required.
Other Complications
Individuals who have had fractures, dislocations, or separations, or have undergone surgeries for shoulder injuries might experience continued pain. After an injury, especially of the rotator cuff, the individual may experience stiffness and might not be able to freely move the joint.
