Arm slings are used to support and rest the arm, shoulder, elbow or wrist, often after an injury or procedure. A sling that is fitted badly can leave the arm hanging too low, strain the neck and feel uncomfortable. A few simple checks make a big difference.
If you have been given a sling by a hospital or clinic, always follow the specific instructions you were given about how long to wear it, what movements to avoid and any exercises to do.
Common types of arm sling
- Pouch or envelope slings: a fabric pouch that holds the forearm, with a strap around the neck or across the back.
- Collar-and-cuff slings: a padded loop around the wrist connected to a neck strap, which lets the elbow hang more freely.
- Immobiliser slings: include an extra strap around the body to keep the arm close to the torso, often used after shoulder injuries or surgery.
- Triangular bandage slings: a first aid option made from a triangular cloth.
How to put on a pouch sling
- Support the injured arm with your other hand and bend the elbow to roughly a right angle, or as instructed.
- Slide the arm into the pouch so the elbow sits snugly in the closed end.
- Check the hand position. The pouch should reach to the wrist or knuckles so the wrist does not droop over the edge.
- Bring the strap around behind your neck or across your back and fasten it to the pouch.
- Adjust the height so your hand sits slightly higher than your elbow, unless told otherwise. This helps limit swelling in the hand.
- Add padding where the strap meets your neck if it rubs.
Signs your sling needs adjusting
- Your hand is lower than your elbow
- The strap digs into your neck or causes headaches
- Your fingers feel cold, numb or tingly, or look pale or blue
- Your shoulder is pulled up towards your ear
Seek medical advice promptly if numbness, colour changes or swelling in the hand do not settle after adjusting the sling.
Daily life with a sling
Sleeping
Many people find sleeping semi-upright, propped with pillows, more comfortable. Ask your clinician whether you should keep the sling on overnight.
Dressing
Loose, front-opening tops are easiest. Put the injured arm into sleeves first and take it out last.
Washing
Follow your instructions on whether the sling can come off for washing, and support the arm against your body if it does.
Keeping other joints moving
Unless told otherwise, gently moving the fingers can help keep the hand from stiffening. Your clinician may give specific exercises for the elbow or shoulder.
Frequently asked questions
How long should I wear a sling?
This depends entirely on the injury or procedure. Follow your healthcare professional’s advice rather than a general rule.
Which side does the strap go?
Most pouch slings fit either arm; the strap usually runs around the neck towards the uninjured side. Follow the product instructions.
