Shoulder Dislocation & Subluxation

A shoulder dislocation occurs when the head of the humerus (upper arm bone) completely slips out of the shoulder socket. A subluxation is a partial dislocation, where the bone shifts out of place but still maintains some contact with the joint. Because the shoulder joint is the most mobile joint in the body, it’s also the most prone to instability. Dislocations and subluxations are common in sports injuries, falls, and accidents, and once the shoulder has dislocated, the risk of recurrence is much higher.
Diagnosis of Shoulder Dislocation & Subluxation
Shoulder dislocation or subluxation is typically diagnosed with:
-
Medical history review (details of the injury event).
-
Physical exam to check for visible deformity, swelling, and range of motion limitations.
-
Neurological assessment to rule out nerve damage.
-
Imaging tests such as X-rays or MRI to confirm the dislocation and check for fractures, labral tears, or ligament damage.
Treatment for Shoulder Dislocation & Subluxation
After the shoulder is safely put back into place (a procedure called reduction), physical therapy plays a critical role in recovery. Treatment may include:
-
Immobilization with a sling in the early healing phase
-
Manual therapy to restore normal joint mechanics once cleared for movement
-
Strengthening exercises for the rotator cuff and shoulder stabilizers
-
Proprioceptive training to improve joint stability and prevent recurrence
-
Postural correction to reduce stress on the joint
-
Education on avoiding risky positions and movements during recovery
In severe or recurring cases, surgery may be required to repair torn ligaments or stabilize the joint, followed by structured rehabilitation.
Symptoms of Shoulder Dislocation & Subluxation
Symptoms of shoulder dislocation and subluxation can include:
-
Intense, sudden pain at the time of injury
-
A visible deformity where the shoulder looks “out of place” (more obvious in full dislocation)
-
Swelling, bruising, or tenderness around the joint
-
Weakness or inability to move the arm
-
A “slipping” sensation in the shoulder joint (more common with subluxation)
-
Numbness or tingling in the arm if nerves are compressed
Prevention of Shoulder Dislocation & Subluxation
To reduce the risk of future dislocations or subluxations:
-
Strengthen the rotator cuff and upper back muscles to support the joint
-
Perform balance and stability exercises for the shoulder
-
Avoid positions that stress the joint excessively (e.g., extreme overhead motions)
-
Use protective gear during contact sports
-
Seek early treatment if the shoulder feels unstable or “slips” frequently
-
Follow through with post-injury rehab to lower the chance of re-injury
