A separated shoulder is an injury to the ligaments that hold your collarbone to your shoulder blade. In a mild separated shoulder, the ligaments may just be stretched. In severe injuries, ligaments may be completely ruptured.

In most people, a separated shoulder doesn't usually require surgery. Instead, conservative treatment — such as rest, ice and pain relievers — is often enough to relieve the pain. Most people regain full shoulder function within a few weeks after experiencing a separated shoulder.

• Shoulder or arm weakness

The most common cause of a separated shoulder is a blow to the point of your shoulder or a fall directly on your shoulder. The injury may stretch or tear the ligaments that hold your collarbone to your shoulder blade.

A separated shoulder can usually be identified during a physical exam. X-rays can sometimes confirm the diagnosis and determine the severity of the injury. But in many people who have a separated shoulder, early X-rays are often normal.

Most people fully recover from a separated shoulder with conservative treatment. Continued shoulder pain is possible, however, if:

• You have a severe separation that involves significant displacement of the collarbone
• You develop arthritis in your shoulder
• Other structures around your shoulder, such as the rotator cuff, are damage

You may be at higher risk of a separated shoulder if you participate in contact sports, such as football and hockey, or in sports that may involve falls — such as downhill skiing, gymnastics and volleyball.
