How to Fit an Arm Sling

Slings are orthopedic devices designed to immobilize an injured extremity. Slings are particularly useful in reducing pain. People promote the healing process by wearing an arm sling and protecting the arm from further injury. Slings are bulky and have a serviceable look. They are somewhat awkward, and the pouches are usually too large and not custom-made. Slings accommodate a variety of sizes and allow for more movement than prescribed. The key to sizing is a proper fit. Make sure the sling fits properly before use.

Things You'll Need

• Tape measure
• Table
• Pillow

Instructions

1. Measure the forearm with a tape measure from the lateral epicondyle (elbow) to the fifth metacarpal-phalangeal joint (wrist) to determine the proper sling size. Slings sell in five sizes: XS (pediatric), 6 to 8 inches; small, 8 to 12 inches; medium 12 to 15 inches; large 15 to 18 inches; XLarge 18 to 20 inches.

2. Support injured arm when fitting slings with assistance. Use uninjured arm to support the injured elbow at a right angle. Let the assistant slide the sling over the elbow, fitting it snugly in the pocket formed by the unopened end of the sling. When fitting the sling without assistance, sit comfortably at a table, with elbow of injured arm bent 90 degrees at a right angle. Place the injured arm on a pillow and slide the sling onto the arm from the elbow. If unable to pull the strap up and over the shoulder, attach and lift it over the head to the opposite shoulder.

3. Maintain the shoulder in a neutral, relaxed position when fitting the sling. An adequately fitted sling is long enough to support the hand and wrist but does not include the fingers. Shorten sling length by folding the open end inside itself. Keep the injured hand slightly elevated to reduce pain and swelling that may interfere with accurate fitting.

4. Lengthen and shorten the strap by using the two metal “D”-shaped rings, which attach to the sling’s open end. The strap carries the weight of the injured arm, and goes over the uninjured arm’s shoulder. Attach the strap by threading the strap through both D-rings. Loop the end of the strap back over the ring farthest from the body, and back under the second ring near the body to lock in place. Shorten the strap length at the D-ring by pulling more strap length through prior to locking. Do not make the strap adjustments too short. This causes discomfort by putting the shoulder into a shrugged position.

Tips & Warnings

• To remove the sling, slip the strap over your head. Unbuckling the strap is not necessary.

• This device will not prevent or eliminate any risk of injury. Do not over-tighten the straps. If there are any signs of swelling, pain or skin irritation, discontinue immediately and consult a medical professional.
