What an immobiliser is for

The NSW Emergency Care Institute describes a shoulder immobiliser as a device that limits shoulder and arm movement after a shoulder dislocation, separation or surgery, a collarbone separation, or a rotator cuff injury. It is different from a simple arm sling, which mainly takes the weight of the forearm, and different again from the soft compression supports sold for sport.

Post-surgery immobilisers often add a pillow at the waist. Enovis says its Quick-Fit immobilizer is indicated after rotator cuff repairs, Bankart procedures and dislocations, and that the waist pillow can be slid forward or back to set the arm's rotation. Your surgical team decides that position.

Because this is a prescribed device, this page does not recommend a substitute for it. If you have not been given one and think you need one, see a clinician.

How it should sit

• Elbow bent at about a right angle. MedlinePlus advises keeping the elbow at a 90 degree angle, with the sling supporting the wrist and hand.
• Elbow tucked back. Enovis's fitting steps position the elbow as far back in the sling as possible.
• Straps secure but not cutting in. Enovis advises contacting your medical professional right away for pain, swelling, changes in sensation or any unusual reaction, and never wearing the support over an open wound.
• Hand warm and pink. MedlinePlus lists a hand or fingers that are darker or feel cool, and numbness or tingling, as reasons to call the doctor.

Sleeping in a shoulder immobiliser

The Emergency Care Institute says adults should wear the sling in bed for the recommended period unless told otherwise, and that children should have it removed while sleeping because of a choking risk. It suggests sleeping on your back or on the unaffected side, with a pillow under the injured arm, and on your side a pillow behind your back so you do not roll onto the injured arm.

After rotator cuff, ligament or labral surgery, MedlinePlus suggests propping your upper body on pillows rather than lying flat, or using a reclining chair. Ask your surgeon how long to sleep this way.

Washing, dressing and moving the rest of you

• Bathing. The Emergency Care Institute says you can remove the sling to bathe or shower if allowed, keeping your arm close to your body. Dry your skin well, especially under the armpit, to prevent irritation.
• Dressing. Loose, front-opening tops are easiest. Put the injured arm in first and take it out last.
• Keep the other joints moving. MedlinePlus suggests moving the fingers, hand and wrist 3 to 4 times during the day, 10 to 15 times per session, and squeezing the shoulder blades together on the same schedule, unless your surgeon says otherwise. The Emergency Care Institute adds gentle neck exercises to prevent stiffness.
• Do not lift, lean or pull with the arm. MedlinePlus lists these among the things to avoid after shoulder surgery.

Coming out of the immobiliser

MedlinePlus says to keep the sling on at all times unless your surgeon says otherwise, and that when the surgeon says it is time, you start letting the arm hang loosely at your side for longer periods each day. A physical therapist usually guides passive exercises first, then home exercises. Do not shorten or lengthen the time on your own.

What to look for when you buy

Questions people ask

How long do you wear a shoulder immobiliser?

Your surgeon or doctor decides, and it varies with the injury and operation. MedlinePlus says to keep it on unless told otherwise and then wean off as instructed.

Do you sleep in a shoulder immobiliser?

Adults usually do for the recommended period, according to the Emergency Care Institute. Children should have a sling removed for sleep because of a choking risk.

Can I take my shoulder immobiliser off to shower?

Often yes, if your clinician allows it. Keep the arm close to your body and dry the armpit well.

What is the difference between a sling and a shoulder immobiliser?

A sling mainly supports the forearm. An immobiliser also holds the arm against the body to limit shoulder movement, often with a waist strap or pillow.
