Shoulder Dislocation

WHAT YOU NEED TO KNOW:

What is a shoulder dislocation?

A shoulder dislocation occurs when the top of your arm bone (humerus) moves out of the socket in your shoulder blade. Shoulder dislocation can happen at any age but is not common in younger children.

Shoulder Anatomy

What causes a shoulder dislocation?

  • A fall on an outstretched arm
  • A hard hit to the back of your arm
  • A hard pull on your arm
  • Loose tissues around your shoulder joint that allow the joint to move more than it should
  • Swinging your arm forcefully over your head
  • Strong, repeated shoulder muscle movements that can happen during a seizure or electric shock

What are the signs and symptoms of a shoulder dislocation?

  • Shoulder and arm pain that worsens with movement
  • A bump in front of or behind your injured shoulder
  • Different shapes for each shoulder
  • Redness and swelling in your injured shoulder
  • Muscle spasms in your injured shoulder
  • Weakness, numbness, or tingling in your injured shoulder and arm

How is a shoulder dislocation diagnosed?

Your healthcare provider will ask about your signs and symptoms. He or she will compare the shape of your shoulders. He or she may touch areas of your shoulder and arm to see if you have decreased feeling. Your provider may also check your arm strength and movement. Tell him or her if you have had a shoulder dislocation in the past. You may also need the following:

  • X-ray, CT, or MRI pictures may be taken to look at the bones in your shoulder or to check for tissue damage. You may be given contrast liquid before the pictures are taken to help healthcare providers see the pictures better. Tell the healthcare provider if you have ever had an allergic reaction to contrast liquid. Do not enter the MRI room with anything metal. Metal can cause serious injury. Tell the healthcare provider if you have any metal in or on your body.
  • An arthrogram is an x-ray taken after contrast liquid is injected into your injured joint. This test is used to look at the bones and muscles in your shoulder joint. Tell the healthcare provider if you have ever had an allergic reaction to contrast liquid.

How is a shoulder dislocation treated?

Treatment depends on how badly your shoulder is dislocated, and if there is damage to bone and nearby tissues. You may need any of the following:

  • Manual reduction is a procedure healthcare providers use to move your dislocated humerus back into place with their hands. Weights may also be used to help pull your humerus into place. You may need a muscle relaxer, sedative, or general anesthesia before this procedure.
  • Prescription pain medicine may be given. Ask your healthcare provider how to take this medicine safely. Some prescription pain medicines contain acetaminophen. Do not take other medicines that contain acetaminophen without talking to your healthcare provider. Too much acetaminophen may cause liver damage. Prescription pain medicine may cause constipation. Ask your healthcare provider how to prevent or treat constipation.
  • A sling, splint, or brace may be needed after your shoulder dislocation is treated. A sling or splint will limit shoulder movement while supporting it. A brace protects your shoulder from injury after treatment. Ask your healthcare provider for more information about slings, splints, and braces.

  • Physical therapy may be used to teach you exercises to help improve movement and strength, and to decrease pain.
  • Surgery may be needed to repair damaged tissues around your shoulder joint. You may also need a bone graft to repair your shoulder. A bone graft is artificial bone used to replace your damaged bone. You may also need surgery if your shoulder dislocates often.

What can I do to care for my shoulder?

  • Apply ice to your shoulder. Ice helps decrease swelling and pain. Ice may also help prevent tissue damage. Use an ice pack, or put crushed ice in a plastic bag. Cover it with a towel before you place it on your shoulder. Apply ice for 15 to 20 minutes every hour or as directed.
  • Rest your shoulder. Rest helps your muscles and tissues heal. Avoid activities that cause pain or use an overhead arm motion. Your healthcare provider will tell you when it is safe to return to sports or other daily activities.

When should I seek immediate care?

  • Your injured shoulder and arm become pale or cold.
  • You cannot move your injured shoulder and arm.
  • You have increased redness or swelling in your injured shoulder.
  • Your shoulder becomes dislocated again.

When should I contact my healthcare provider?

  • You have a fever.
  • You have increased pain in your injured shoulder and arm even after you rest and take your medicine.
  • You have new weakness or numbness in your injured shoulder and arm.
  • You have questions or concerns about your condition or care.
