What Is a Shoulder Dislocation?

A shoulder dislocation happens when the ball at the top of the upper arm bone (the humeral head) comes completely out of the shallow socket of the shoulder blade (the glenoid). The shoulder is the most mobile joint in the body, and that mobility comes at the cost of stability.

•   Complete dislocation: the humeral head fully leaves the socket and usually will not return on its own. Most dislocations move forwards (anterior), though backwards and downward dislocations also occur.
•   Subluxation: the humeral head shifts partly out of the socket and slips back in. This can feel like a brief slipping, catching or dead-arm sensation rather than an obvious dislocation.

Because the joint is stabilised by soft tissue as much as by bone, a dislocation may also damage the surrounding structures. The rim of cartilage around the socket (the labrum) may be torn, producing a labral tear, and the capsule and ligaments may be stretched or detached. The bone at the front of the socket or the back of the humeral head may be dented or chipped. A rotator cuff injury may also occur, which becomes more likely with increasing age. These associated injuries are one reason a shoulder specialist may want to review the shoulder even after it has been reduced.

What Are the Symptoms of a Dislocated Shoulder?

The symptoms of a dislocated shoulder usually begin suddenly at the moment of injury and are difficult to ignore. Where clinically typical, they include:

•   Sudden, severe shoulder pain
•   A visibly altered shoulder contour — the shoulder may look squared off, and the arm may appear displaced
•   The arm being held slightly away from the body, supported by the other hand
•   Swelling and bruising around the joint
•   Marked difficulty or inability to move the arm
•   Weakness in the arm
•   A sense of instability, slipping or giving way — often more noticeable after the shoulder has been reduced
•   Numbness, tingling or pins and needles in the arm or hand

After a shoulder has been put back into place, pain and swelling usually settle over the following days. Symptoms that persist beyond that period, particularly weakness or a feeling that the shoulder is not secure, are worth having assessed.

When to Seek Urgent Medical Attention

Attend an emergency department, rather than waiting for an outpatient appointment, if:

•   The shoulder is still out of position and you cannot move the arm
•   The arm or hand is numb, weak, cold, pale or discoloured
•   Pain is severe and not manageable
•   The injury involved a significant fall, collision or high-energy trauma
•   There is an open wound over the joint, or you suspect the bone may also be broken

A dislocated shoulder should be reduced by a trained clinician. Do not ask someone to pull the arm back into place for you, and do not attempt to force it yourself.

What Causes a Shoulder to Dislocate?

Most shoulder dislocations follow a specific incident in which force is applied to the arm while it is in a vulnerable position — typically raised and rotated outwards.

Common causes include:

•   Contact and collision sports — rugby, football, basketball, martial arts and similar activities
•   Falls — particularly onto an outstretched arm, or directly onto the shoulder
•   Direct trauma to the shoulder, including road traffic and workplace accidents
•   Forceful or sudden arm movements, such as a heavy overhead lift or a tackle that wrenches the arm
•   A previous dislocation, which may leave the stabilising structures stretched or torn
•   Underlying shoulder instability, where the joint is loose enough that a relatively minor movement is sufficient

Where a dislocation happens during training or competition, the shoulder is often assessed alongside the wider picture of sports injuries and the demands of the sport involved.

Shoulder Reduction

Reduction is the process of returning the humeral head to its socket. It is usually performed in an emergency department, often with pain relief or sedation, and an X-ray is generally taken afterwards to confirm the position and to check for fracture.

A dislocated shoulder should be assessed before and after reduction by a trained clinician. Forceful attempts at self-reduction, or reduction by someone untrained, may cause additional damage to the surrounding soft tissue, bone, nerves or blood vessels, and may make a fracture worse if one is present.

Immobilisation and Pain Management

After reduction, a short period in a sling is commonly advised to rest the joint while the initial pain and swelling settle. Simple analgesia may be used for symptom control. The duration varies between individuals, and prolonged immobilisation is generally avoided because of the risk of stiffness.

Immobilisation is not universally required or applied in the same way for every patient, and the period advised depends on the injury and on your assessment.

Physiotherapy and Rehabilitation

Structured rehabilitation is a central part of non-surgical management, and also follows surgery where surgery is performed. A rehabilitation programme is typically progressive and may address:

•   Restoring range of motion as pain settles
•   Strengthening the rotator cuff, which contributes to keeping the humeral head centred in the socket
•   Strengthening the surrounding shoulder stabilisers, including the muscles controlling the shoulder blade
•   Movement control and proprioception: retraining how the shoulder senses and controls its own position
•   Graded return to loading, and then to sport-specific or work-specific activity

Rehabilitation may improve strength, control and confidence in the shoulder. It does not remove the possibility of a further dislocation, particularly where there is significant structural damage, and outcomes vary between individuals.

When May Surgery Be Considered?

Surgery is not automatically required after a shoulder dislocation. Many first-time dislocations are managed without it. Surgical options may be discussed where:

•   The shoulder has dislocated repeatedly
•   Instability persists and interferes with daily activities, work or sleep
•   Imaging shows significant structural injury, such as a substantial labral tear or bone loss from the socket or humeral head
•   Appropriate conservative management and rehabilitation have not restored stability
•   The demands of your sport or occupation place the shoulder at high risk of further episodes

Where surgery is discussed, the reasoning, alternatives, expected recovery and risks are explained so that you can make an informed decision. Individual assessment is required in every case.

What type of doctor should I see for a dislocated shoulder?

A dislocated shoulder should first be assessed at an emergency department, where it can be reduced safely. For follow-up, an orthopaedic surgeon with a shoulder or sports interest is generally the appropriate specialist. They can identify associated injuries to the labrum, ligaments, rotator cuff or bone, assess stability, and plan rehabilitation or discuss surgery where relevant.

Does a dislocated shoulder always need surgery?

No. Many shoulder dislocations, particularly first-time dislocations, are managed without surgery using a short period of immobilisation, pain relief and structured rehabilitation. Surgery may be discussed where dislocations recur, where instability persists, where imaging shows significant structural damage, or where the demands of sport or work place the shoulder at high risk.

Can a dislocated shoulder heal without surgery?

In many cases, yes. Once the shoulder has been reduced, the surrounding tissues may settle with appropriate rest, pain management and rehabilitation aimed at restoring movement, strength and control. Whether non-surgical management is sufficient depends on the extent of damage and how stable the shoulder is on assessment, so individual review is important.

How long does a dislocated shoulder take to recover?

Recovery varies. Initial pain and swelling often settle within a few weeks, while restoring strength, control and confidence generally takes longer, and returning to contact or overhead sport takes longer still. The timeline depends on the severity of the dislocation, associated injuries, whether surgery was performed, your general health and rehabilitation progress.

Why does my shoulder keep dislocating?

Repeated dislocation usually indicates that the structures stabilising the joint have not healed in a way that holds the humeral head in place. This commonly involves the labrum, capsule and ligaments, and in some cases bone loss from the front of the socket. Assessment can identify which structures are contributing in your case.

Can physiotherapy help after a shoulder dislocation?

Physiotherapy is a core part of recovery, whether or not surgery is performed. A structured programme works on restoring range of motion, strengthening the rotator cuff and shoulder blade muscles, and improving movement control. It may improve function and confidence in the shoulder, though it cannot remove the possibility of a further dislocation.

When can I return to sports after a shoulder dislocation?

There is no fixed date. Return is guided by clinical assessment — whether pain has settled, movement and strength have been restored, and the shoulder is stable in the positions your sport demands. Contact and overhead sports are usually resumed later than low-demand activities, and the treatment you received affects the timeline.

Should I still see a specialist if my shoulder has already been put back in place?

Reduction restores the joint position but does not treat any structural damage caused by the dislocation. Labral, ligament, rotator cuff and bony injuries may not be apparent initially. A specialist review assesses stability, clarifies what was injured, and guides rehabilitation and further treatment where required.
