Dislocated shoulder (shoulder instability)

A dislocated shoulder is when the top of the upper arm bone comes out of its socket in the shoulder; it usually happens in a fall or during sport, and most often the bone comes out forwards. Once a shoulder has dislocated, it may tend to dislocate again or slip partly out of place; this is called shoulder instability. Exercise after the shoulder has been put back is the foundation for regaining its strength and movement.

Symptoms

  • Not being able to move the arm.
  • The shoulder looking out of place or misshapen.
  • Pain, swelling and bruising.

What to do if your shoulder dislocates

  • Do not try to put the shoulder back yourself; go to A&E as soon as possible. Do not drive; call 112 if needed.
  • While you wait, support your arm in a sling or towel and keep it still.
  • You can apply ice wrapped in a towel for up to 20 minutes every 2–3 hours.

Treatment and recovery

The dislocation is usually confirmed with an X-ray, and a doctor puts the shoulder back in place under local anaesthetic or sedation. A sling is then given. Most people recover in 6–12 weeks; getting the shoulder’s full strength and function back can take up to a year.

Surgery is sometimes recommended to reduce the chance of the shoulder dislocating again. Younger people may be referred to a shoulder specialist.

Risk of dislocating again

In an analysis that combined 10 studies and 1,324 people, about 39% of shoulders that had dislocated forwards for the first time dislocated again or slipped out of place. Factors that increase the risk:

  • Being aged 40 or under (the strongest factor)
  • Being male
  • Having naturally loose joints

Redislocation was less common in people who also had a fracture of the bony bump on the upper outer part of the arm bone.

After the shoulder has been put back

1

Sling

The sling is for comfort. You can take it off when sitting and rest your arm on a pillow; if there is no fracture, it is usually not worn after 2 weeks.

2

Position to avoid

In the first weeks, you can avoid lifting your arm above shoulder height and moving your arm out to the side while turning your hand up towards the ceiling, especially with force.

3

Elbow and wrist

You can start bending your elbow, turning your palm and moving your wrist straight away.

4

Ice and painkillers

Ice wrapped in a towel and paracetamol taken as directed on the packet can ease the pain.

For other causes of shoulder pain, see the rotator cuff tear and frozen shoulder guides.

Exercises at home

Six exercises to strengthen the shoulder

You can start once you have stopped using the sling and your doctor or physiotherapist feels it is appropriate. Start slowly and stop any movement that causes pain. In the first weeks, do not lift your arm above shoulder height.

Shoulder blade squeeze

Shoulder blade squeeze

Stand or sit up straight. Without lifting your shoulders towards your ears, squeeze your shoulder blades back and slightly down. Hold for 5 seconds, then relax.

10 reps, 2–3 times a day
Door frame external rotation

Door frame external rotation

Stand with your painful side next to a door frame. Bend your elbow to 90 degrees and keep your arm against your side; you can put a small folded towel in between. Press the back of your hand against the door frame without letting your arm move. Hold for 30–45 seconds, pressing only as hard as you can without increasing the pain.

5 reps, 1–2 times a day
Wall slides

Finger walk up the wall

Stand facing a wall. Walk your fingers up the wall to a comfortable height, hold briefly, then slowly walk them back down. In the first weeks, do not force your arm above shoulder height.

10 repetitions, 3–4 times a day
Scaption (angled arm raise)

Scaption (angled arm raise)

Stand with your arms by your sides and your thumbs pointing up. Raise your arms forwards and slightly out to the sides, at an angle of about 30 degrees, up to shoulder height; you can hold a light weight in each hand. Lower them slowly, without lifting your shoulders towards your ears.

10 reps, 2–3 sets
Resistance band row

Resistance band row

Tie a resistance band to a door handle or another sturdy anchor at chest height. Holding the ends of the band and keeping your elbows close to your body, pull back and squeeze your shoulder blades together. Slowly return to the start.

10–15 reps, 2–3 sets
Side-lying external rotation

Side-lying external rotation

Lie on your pain-free side. Bend the elbow of your top arm to 90 degrees and rest it against your waist. Holding a light weight (a full water bottle will do), lift your hand towards the ceiling while keeping your elbow still, then lower it slowly.

10–15 reps, 2–3 sets

Frequently asked questions

Can I put my shoulder back in myself?

No, do not try to put the shoulder back yourself. Go to A&E as soon as possible; do not drive, and call 112 if needed.

How long should I wear the sling?

The sling is for comfort. You can take it off as the pain eases and rest your arm on a pillow when sitting. If there is no fracture, it is usually not worn after 2 weeks; if you were given a specific time, you can follow that.

Will my shoulder dislocate again?

It can. In a combined analysis of studies, about 39% of shoulders that had dislocated forwards for the first time dislocated again or slipped out of place. Being aged 40 or under, being male and having naturally loose joints increase this chance. Physiotherapy strengthens the shoulder muscles; in younger people and after repeated dislocations, surgery may also be discussed.

When can I drive and get back to sport?

You should not drive while wearing a sling; most people can drive after 4–6 weeks, once their arm has enough strength and movement. Lighter activities can be resumed after about 6 weeks; a full return to some sports can take up to 16 weeks. Your doctor or physiotherapist will tell you when it is safe.

When should you see a doctor?

  • If your shoulder has come out of place or looks misshapen: go to A&E straight away
  • If pain and stiffness are not settling or are getting worse
  • If your shoulder has dislocated again or often feels as if it is slipping out of place
  • If you have numbness, tingling or weakness in your arm or hand
