Arm sling

An arm sling supports an injured forearm, wrist or hand. It is made from a triangular bandage tied around the neck. The injured arm rests in the sling and is relieved of weight.

When do you use an arm sling?

Use an arm sling to support the arm after an injury to the fingers, wrist or forearm up to the elbow, such as a fracture, large wound or bruise. The whole forearm, from the elbow to the fingers, rests in the sling, which is tied around the neck.

How do you use an arm sling?

The hand and fingers should sit slightly higher than the elbow. This prevents venous congestion, where blood flows down into the hand and fingers but cannot drain properly, causing swelling and a painful, throbbing feeling.

If the problem is higher up the arm or in the shoulder, use a broad sling. This is a band over the shoulder that supports the wrist while leaving the rest of the forearm and elbow free.

If the injury has just occurred and you have nothing to make a sling with, use your healthy arm to support the injured arm.

How do you apply an arm sling?

Follow these steps:

• Step 1: Place the sling against the body and under the injured arm. The point should be at the elbow. The upper part goes over the shoulder of the uninjured arm.
• Step 2: Take the lower part of the sling and place it over the shoulder of the injured arm.
• Step 3: Tie the ends together with a reef knot where it will not irritate the skin. Fold the point at the elbow forwards and secure it with a safety pin or plaster/tape.
• Step 4: Make sure the fingers protrude slightly.

Check that the sling is comfortable and that the hand is slightly higher than the elbow to prevent congestion.
