Understanding Shoulder Dislocation and Instability
What patients commonly notice
The shoulder may move out of position after injury and can remain vulnerable to recurrent instability. The exact pattern and severity can vary, so a clinical assessment is important before deciding on treatment.
Common symptoms
- A visible deformity during an acute dislocation
- Apprehension or slipping with certain arm positions
- Repeated episodes, pain or reduced confidence in the shoulder
Causes and risk factors
There may be more than one contributing factor. Common possibilities include:
- A fall, collision or forceful overhead injury
- Labral or ligament damage after dislocation
- Generalised joint laxity in some patients
How is shoulder dislocation and instability assessed?
Assessment usually considers pain, strength, stability and both active and passive shoulder movement. X-rays, ultrasound or MRI may be requested when they will help clarify the diagnosis or guide treatment.
Treatment options
Treatment is matched to the diagnosis, symptom severity, general health and the activities you need to return to. Options may include:
- Urgent reduction and assessment for an acute dislocation
- Rehabilitation to restore movement and dynamic stability
- Stabilisation surgery for recurrent or high-risk instability
Surgery is not automatically the first step. When it is considered, the likely benefit, alternatives and recovery requirements should be discussed clearly.
Common questions
Is a dislocated shoulder an emergency?
Yes. A visibly dislocated shoulder should be assessed and reduced promptly by a trained clinician. Do not repeatedly attempt to force it back yourself, particularly if there is numbness or loss of circulation.
What is the chance that my shoulder will dislocate again?
Recurrence is more common in younger active patients and after damage to the labrum or bone. Age, activity, number of episodes and imaging findings help estimate individual risk.
When is stabilisation surgery recommended?
Surgery may be considered after recurrent episodes, persistent apprehension, significant labral or bone injury, or a first dislocation in a patient at high risk of recurrence.
