Shoulder Dislocation

A shoulder dislocation is an injury in which the rounded top of the upper arm bone slips fully out of the shallow socket it normally sits in. The arm suddenly cannot move, the pain is intense, and the shoulder often looks squared off. This page explains what happens, what to do first, how doctors decide on treatment and when surgery, including in turkey, is worth considering.

What is a shoulder dislocation?

The shoulder is a ball-and-socket joint. The ball (humeral head) is much larger than the socket (glenoid), a little like a golf ball resting on a tee. That design gives the shoulder the widest range of movement of any joint, but it also leaves it with little built-in bony protection.

In a dislocation (also called luxation) the ball leaves the socket completely. When it only slips partly and returns by itself, doctors call it a subluxation. Both can stretch or tear the structures that hold the joint together.

Who is affected by a shoulder dislocation?

The shoulder is the joint that dislocates most often in the body. First-time events are most common in young men who play contact or collision sport, such as rugby, judo and football, and in people of all ages who fall onto an outstretched arm. A second peak appears in older adults, where a fall on ice or a slippery floor is the usual trigger.

Age matters for the future as well. The younger a person is at the first dislocation, the more likely the shoulder is to come out again.

How serious is a shoulder dislocation?

A shoulder dislocation is painful but treatable, and most people regain good use of the arm. The reasons to take it seriously are the possible damage to nerves, blood vessels, the rotator cuff and the bone, and the chance of repeat episodes. Anyone who suspects a dislocated shoulder should go to an emergency department rather than wait.

Many readers search for shoulder dislocation treatment in turkey after a second or third episode, so the page also explains when travel is sensible. Later sections cover first aid, the anatomy, classification, tests, rehabilitation, surgery and a realistic outlook.

The shoulder is held together mainly by soft tissue rather than by bone shape, which is why it can dislocate so easily. Understanding these parts makes it clear why treatment choices differ from person to person.

What is the normal structure of the shoulder joint?

Three bones meet at the shoulder: the humerus (upper arm bone), the scapula (shoulder blade) and the clavicle (collarbone). The glenohumeral joint, the true ball-and-socket, is formed by the humeral head and the glenoid, which is only about 2.5 cm wide in most adults.

Around the rim of the glenoid sits the labrum, a ring of tough fibrous cartilage that deepens the socket and gives the ligaments an anchor. Thickened bands of the joint capsule, the glenohumeral ligaments, tighten at the extremes of movement. The most important one for front dislocations is the inferior glenohumeral ligament.

The four rotator cuff muscles (supraspinatus, infraspinatus, teres minor and subscapularis) wrap the joint and pull the ball into the socket as the arm moves. Strong cuff and shoulder blade muscles are the basis of dynamic stability.

Which nerves and vessels lie close by?

The axillary nerve curls around the neck of the humerus just below the joint, and the brachial plexus and main artery of the arm pass in front of it. A dislocation can stretch these structures, which is why doctors test sensation over the outer upper arm and check the pulse at the wrist before and after relocation.

What changes when the shoulder dislocates?

Most dislocations (more than 90%) are anterior, meaning the ball moves forward and down. As it leaves, it commonly tears the labrum off the front-lower rim of the socket, an injury called a Bankart lesion. The ligament and capsule are stretched, and the back of the ball can be dented as it hits the socket edge, a defect called a Hill-Sachs lesion.

In some people a fragment of the socket rim breaks off as well (a bony Bankart). Repeated dislocations can wear down more of the rim until the socket is shaped like a pear instead of a circle. These hidden bone changes are the main reason some shoulders keep coming out.

Doctors describe a shoulder dislocation by the direction of the ball, how often it has happened and what caused it. These labels guide the choice between rehabilitation and surgery.

Which direction can a shoulder dislocation take?

A posterior dislocation is easy to miss on a quick look at an X-ray, so a clear history of a seizure or shock should be shared with the emergency team.

What is the difference between first-time and recurrent shoulder dislocation?

A first-time (primary) episode is treated as an injury that needs relocation and a plan. A recurrent shoulder dislocation means the joint has come out more than once, often with less and less force. Some people reach the point where it slips during sleep or while reaching for a shelf.

Traumatic or atraumatic?

A traumatic dislocation follows a clear injury and usually tears the labrum and capsule. An atraumatic one occurs with little force in people with loose joints or poor muscle control, and it often responds well to specialised rehabilitation rather than surgery. A third group has voluntary or habitual dislocation, which needs careful assessment before any operation.

Why does the type change treatment?

A young contact-sport player with a torn labrum and a bone defect may be offered a stabilising operation after the first or second episode. An older adult with a rotator cuff injury needs a different approach, and a person with generalised laxity usually starts with months of targeted strengthening. Classification therefore decides the plan.

A shoulder dislocation is diagnosed from the story of the injury, a careful examination and imaging. The aim is to confirm the direction, rule out fractures and nerve injury, and later to find the damage that explains any repeat episodes.

What does the doctor ask and examine at the emergency department?

The team asks how the injury happened, which arm is dominant, whether it has happened before and whether you have had a seizure. They check the pulse, skin colour and sensation, and test the deltoid muscle and the skin over the outer upper arm to look for axillary nerve injury. Tests are repeated after the joint is put back.

Which imaging is used?

An X-ray, usually from more than one angle, confirms the dislocation, its direction and any fracture of the humerus or socket. It is repeated after relocation to show that the ball is centred. Gentle attempts without imaging are a poor idea because a hidden fracture can be made worse.

Once the shoulder has settled, an MRI or an MR arthrogram (MRI with dye injected into the joint) shows the labrum, ligaments and rotator cuff. A CT scan with 3D reconstruction measures bone loss on the socket and the Hill-Sachs defect, which is essential before choosing between soft-tissue and bone-block surgery.

How is recurrent instability assessed in clinic?

After the acute phase, the specialist tests range of movement, strength and joint looseness. The apprehension and relocation tests reproduce the feeling of the ball about to slip. The sulcus sign and the Beighton score assess general laxity. Findings are compared with the other shoulder.

What should you bring to a remote review?

A good remote opinion starts with the emergency summary and discharge letter, the X-ray reports and images before and after relocation, any MRI or CT in digital format, and a short timeline of every episode. Note the position of the arm when it slipped, the sport you play and the work you do. Our medical record review guide explains how files are checked.

Most first-time dislocations are treated without surgery, starting with relocation and followed by protection, movement and strengthening. The order matters, and the details depend on age, activity and what the scans show.

What happens at the first visit?

Urgent local care comes first. The joint is put back in place (a closed reduction) in the emergency department, usually with pain relief or sedation so that the muscles relax. Gentle techniques such as traction with counter-traction are used, and the shoulder is X-rayed again afterwards. Do not let anyone without training try to pop it back.

How long should the arm stay in a sling?

A sling is worn for comfort for about 1 to 3 weeks, and then gradually discarded. Long periods of immobilisation have not been shown to reduce the chance of repeat episodes, so early gentle movement is usually encouraged. Some centres use an external-rotation brace, but evidence on this is mixed.

What does physiotherapy involve?

Rehabilitation usually runs in phases over 6 to 12 weeks, and often longer for sport:

1. Settle pain and swelling with ice, posture advice and simple pendulum movements in the first week.
2. Restore range of movement from week 2 to 4, avoiding the combined position of arm out to the side and rotated backward.
3. Build rotator cuff and shoulder blade strength from week 4 onward with bands and light weights.
4. Train control and proprioception (joint position sense), then sport-specific drills from week 8 to 12.

Which medicines help?

Simple analgesics such as paracetamol and anti-inflammatory medicines (NSAIDs) can ease pain in the first days if your doctor agrees. A short course of stronger pain relief may be given after reduction. These medicines treat symptoms only and do not repair the labrum, so they should be paired with exercise.

What does the evidence suggest about non-surgical care?

Studies suggest that rehabilitation works well for many older adults and for people with loose joints. In young, active patients with a torn labrum, the chance of another dislocation after non-surgical care is high, and trials show that early arthroscopic stabilisation lowers the repeat rate. That is why a conversation about surgery is reasonable after a first dislocation in a young contact athlete.

Surgery for a shoulder dislocation is aimed at restoring the stabilising structures that failed. The two operations most often used are labral repair for soft-tissue injury and the Latarjet procedure when bone is deficient.

What is arthroscopic labral repair?

In shoulder labral repair, the surgeon uses a camera and small instruments through 3 or 4 keyhole incisions. Small anchors are placed in the socket rim, and the torn labrum and capsule are stitched and tightened back to the bone. It suits people with good bone, a clean Bankart tear and lower-demand sport.

Recovery is typically a sling for about 4 weeks, rehabilitation for 4 to 6 months, and a return to contact sport at around 6 months. Repair on its own has a higher failure rate in young contact athletes with bone loss, which is why scans matter. See the shoulder labral repair in turkey page and the shoulder labral repair cost guide.

What is the Latarjet procedure?

The Latarjet procedure moves a piece of bone called the coracoid process, with its attached tendons, to the front of the socket and fixes it with screws. This adds bone to the rim and creates a sling effect from the transferred tendon, which stops the ball sliding forward. It is a more robust option for significant glenoid bone loss, large Hill-Sachs lesions, previous failed repair and collision sport.

It is a bigger operation with its own risks, discussed below, but it has a low rate of repeat dislocation in the long term. More detail is on the Latarjet procedure in turkey page and in the Latarjet procedure cost guide.

Are there other options?

Other techniques include remplissage (filling the dent on the ball with tendon), bone graft to the socket from the hip bone or a donor, and open capsular shift for loose-jointed patients. Posterior dislocations may need a posterior bone block or capsule repair. The surgeon chooses based on CT and MRI findings rather than a single preferred method.

How do the main options compare?

Not every shoulder dislocation can be prevented, because many follow a sudden accident. You can still reduce the risk of a first episode and the chance of repeat events with sensible habits and good rehabilitation.

How can you lower the risk of a first dislocation?

Strengthen the rotator cuff and the muscles around the shoulder blade, including the serratus anterior and lower trapezius, and keep a good range of movement. Athletes should learn safe falling and tackling techniques, with the arm tucked in rather than outstretched. Protective equipment and well-fitted straps can help in some sports.

How can you prevent a repeat dislocation?

Complete the full rehabilitation programme rather than stopping when pain eases. Most plans last at least 3 months and include a graded return to sport. A stabilising brace or taping may help for a season of contact sport while a decision about surgery is made. Do not return to full contact before strength and control are close to the other shoulder.

What cannot be prevented?

Accidents, seizures and inherited ligament looseness cannot be fully controlled. If you have epilepsy, good seizure control and medication review lower the risk of posterior dislocation. People with generalised laxity benefit from lifelong core and shoulder conditioning.

Which habits protect the shoulder in daily life?

Avoid reaching and pulling with a fully raised, turned-out arm when carrying heavy items. Keep stairs and floors free of slip hazards, especially for older adults, and use handrails. Check your home for objects that cause trips, and keep vision and footwear up to date.

Most people with a shoulder dislocation recover good function, and the outlook depends strongly on age, the damage found and the treatment chosen. Honest expectations help with planning work and sport.

What is the typical shoulder dislocation recovery time?

The shoulder dislocation recovery time after a first, uncomplicated episode is about 6 to 12 weeks for daily use and 3 to 4 months for sport. After labral repair, expect around 4 weeks in a sling, light desk work in 2 to 4 weeks, rehabilitation for 4 to 6 months and contact sport at roughly 6 months. After a Latarjet, the timetable is similar, with some centres allowing earlier movement and a return to contact sport between 4 and 6 months.

What is the long-term outlook?

Without surgery, a large share of young athletes dislocate again, whereas in older adults the repeat risk falls steeply with age. After a well-selected stabilisation operation, most people return to their previous level of sport and report stable shoulders. A small group still has pain, stiffness or occasional apprehension.

When can you drive, work and travel?

Many people return to desk work in 1 to 2 weeks and driving in 4 to 6 weeks, depending on the procedure, the arm involved and local rules. Manual work with overhead loads can take 3 to 6 months. Ask your surgeon before flying and before lifting luggage.

What about arthritis later in life?

People who dislocate repeatedly or who have lost bone have a higher chance of shoulder arthritis over decades. Stabilising the joint and keeping the muscles strong appear to lower that risk, although no operation removes it entirely. See our page on shoulder osteoarthritis for what that looks like and the shoulder hub for other problems.

How should you plan your recovery?

Set goals with your physiotherapist, track strength against the other arm and expect good and bad days. A staged return to sport, rather than a calendar date, is the safest guide. Our rehabilitation guide describes what to expect.
