What is dislocation of the shoulder?
If you have dislocated your shoulder, your upper arm bone (humerus) has moved out
of your shoulder joint. This is the most frequently dislocated major joint of your
body. Dislocation is often caused by a significant force that separates your shoulder
joint's ball (the top rounded portion of your upper arm bone) from your joint's socket
What causes a shoulder dislocation?
Your shoulder can dislocate in several ways, including:
- Forward and downward dislocation. These are the most common types of dislocations. They usually result from falling
on your outstretched hand or on your shoulder itself.
- Backward dislocation. This type of dislocation may be caused by a direct blow to the front of your shoulder,
or the violent twisting of your upper arm.
Your shoulder can be either partially or completely dislocated. Partial dislocation
is when the head of your upper arm is partially out of your shoulder socket. Complete
dislocation is when the head of your upper arm is completely out of your shoulder
What are the symptoms of a shoulder dislocation?
The following are the most common symptoms of a dislocated shoulder. However, you
may experience symptoms differently. Symptoms may include:
- Pain in your upper arm and shoulder, which is usually worse when you move them

The symptoms of a dislocated shoulder may resemble other conditions or medical problems.

Can a dislocated shoulder be prevented?
Maintaining muscle strength and flexibility can help prevent shoulder dislocations.
Once your shoulder is dislocated, physical therapy may help prevent you from dislocating
it in the future. Through restoring your shoulder’s range of motion and physical strength,
your risk for dislocation decreases.
How is a shoulder dislocated managed?
Once your shoulder has been placed back into the socket joint, your healthcare provider
may advise you to keep your shoulder immobilized in a sling or other device for several
weeks after treatment. Resting and applying ice to the affected area several times
a day will help your pain and swelling diminish.
After your pain and swelling subside, you may need to do some rehabilitation exercises
to help restore your shoulder’s range of motion and strengthen your muscles.
