An arm sling supports and immobilizes the upper extremity following an injury to the wrist, arm, or shoulder. Its purpose is to hold the injured limb in a fixed, comfortable position to minimize movement and stress on the affected joints and tissues. Maintaining this rest helps reduce pain and inflammation, promoting an optimal environment for healing. Correct application and adjustment are necessary to ensure the device functions effectively and avoids causing additional complications or discomfort.
Step-by-Step Guide for Placement
Ensure you have the appropriate size, as an ill-fitting sling will not fully support the forearm or will allow excessive movement. With the injured arm relaxed, gently slide it into the pouch, ensuring the elbow is seated securely and completely in the back corner pocket of the fabric. This deep seating ensures the entire weight of the forearm is borne by the sling material, not the shoulder muscles.
Next, bring the long strap up and over the back, resting it against the opposite, uninjured shoulder or neck. Thread the strap through the buckle or loop near the hand to create the supporting loop. Secure the strap using the provided fasteners, typically Velcro tabs, but do not tighten it fully yet.
Proper Positioning for Healing
The most important adjustment is setting the correct elbow angle, which should be bent at approximately 90 degrees. Achieve this right angle by shortening or lengthening the neck strap until the forearm is positioned parallel to the ground or slightly elevated. The hand should be at or slightly above the level of the elbow. This elevation encourages blood flow and prevents fluid from pooling in the wrist and fingers, reducing swelling.
Confirm that the wrist is fully supported by the sling fabric and does not droop below the edge, which strains the wrist joint. For comfort, position the neck strap so pressure rests on the uninjured side of the neck, using a soft pad to protect the skin from irritation. If included, fasten the waist strap around the body to stabilize the arm against the torso, preventing swinging.
Managing Daily Life While Immobilized
Navigating daily routines requires adjustments to protect the injured arm while maintaining comfort and hygiene. When dressing, wear front-opening shirts or tops. Always slide the injured arm into the sleeve first. The uninjured arm should pull the garment over the body while the injured arm remains relaxed and passive.
For bathing, the sling can be removed, but the arm must be kept close to the body to limit movement. Use waterproof dressings to keep any surgical wounds dry. Utilizing a shower is simpler than a bath; resting the injured arm on a stable surface while washing helps maintain stillness. After showering, a terry cloth robe is helpful for drying, eliminating the need to rub with a towel.
When sleeping, lie on the back or on the unaffected side. Supporting the injured arm with pillows improves comfort and stability. Arrange the pillows to prop the arm up slightly, maintaining the elevation achieved while standing.
To maintain circulation, perform small, gentle movements, such as wiggling the fingers several times daily, to prevent stiffness and promote blood flow. Tingling, numbness, a change in skin color, or a cold feeling in the hand or fingers indicates the sling may be too tight and should be immediately loosened to restore proper circulation.
