A separated shoulder is an injury to one of your body's most mobile joints. The top of your shoulder blade meets the end of your collarbone at what is called the acromioclavicular joint. A separated shoulder is a stretch or tear of one or more of the ligaments of this joint.
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 of a separated shoulder. Most people regain full shoulder function within a few weeks after experiencing a separated shoulder.
Signs and symptoms of a separated shoulder may include:
When to see a doctor
Contact your doctor if you experience tenderness or pain near the end of your collarbone — especially if lifting your affected arm with your other arm eases the pain.
The top of your shoulder blade (acromion) meets the end of your collarbone (clavicle) at the acromioclavicular (AC) joint. A separated shoulder is a stretch or tear of one or more of the ligaments of the acromioclavicular joint.
The most common cause of a separated shoulder is a blow to your shoulder or a fall directly on your shoulder. The fall may stretch or tear the ligaments that stabilize the acromioclavicular joint. This separates the bones in the shoulder, creating a bump at the top of the shoulder.
If you're at risk of falling on your shoulder, you're at risk of a separated shoulder. The risk is particularly high for athletes — especially those who participate in contact sports, such as football and hockey, and in sports that may involve falls, such as downhill skiing, gymnastics and volleyball.
Most people fully recover from a separated shoulder with conservative treatment. Continued shoulder pain is possible, however, if:
Preparing for your appointment
You're likely to start by first seeing your family doctor or a general practitioner. However, if your separated shoulder is severe, you may be referred to a doctor who specializes in bones and joints.
Because appointments can be brief, it's a good idea to come prepared for your appointment. Write down any symptoms you're experiencing and any questions you want to ask your doctor.
Your doctor will have questions for you, too. Being ready to answer them may reserve time to go over any points you want to spend more time on. Your doctor may ask:
What you can do in the meantime
Apply ice to the affected shoulder to reduce pain and swelling. If you're in pain, take an over-the-counter pain reliever.
Often, a separated shoulder can be identified during a physical exam. Your doctor may use an X-ray of the shoulder or other imaging studies to confirm the diagnosis and study the extent of the injury.
A separated shoulder is graded depending on how far your collarbone is separated from your shoulder:
A separated shoulder is usually treated conservatively. Your doctor may recommend:
Most people enjoy a full recovery after conservative treatment — although the more severe the shoulder separation, the longer it'll take to regain comfortable use of your shoulder. A minor separation may heal within a few weeks. A more severe separation may take several weeks to months to heal. You may always have a noticeable bump on the affected shoulder, but it shouldn't affect your ability to use your shoulder.
If pain persists or if you have a severe separation, surgery might be an option. Surgery usually involves measures to stabilize the acromioclavicular joint and re-establish normal bony relationships in the shoulder.
Regular exercise, including strength training, can help you strengthen and protect your shoulders. Start slowly, and increase your intensity gradually. Use proper form and protective gear for your given sport.
