Shoulder abduction orthosis is mainly used in scenarios such as shoulder joint injury, post-rotator cuff repair surgery, conservative treatment or postoperative fixation of proximal humeral fractures. By immobilizing the shoulder joint in an abducted position, it reduces soft tissue tension and promotes healing. In the early stages of rehabilitation, a reasonable fixation angle and wearing duration are the foundation for ensuring therapeutic effects.
First confirm that all components of the orthosis (ratchet plate, Velcro, pads) are intact and undamaged, and that the pads are clean and free from damage. Select the appropriate size based on the patient's body type (common sizes: XS, S, M, L, XL) and perform initial adjustments by referring to the product manual.
Most shoulder abduction orthoses are equipped with an adjustable ratchet plate, typically allowing settings for shoulder abduction angles (e.g., 30°, 45°, 60°, etc.) and forward flexion angles. The first use should be set by a rehabilitation physician or therapist; later adjustments may be made with permission. When adjusting, always operate with both hands, first release the ratchet lock, align the scale, and then tighten the lock.
1. The patient sits or lies semi-recumbent. Place the main body of the orthosis on the affected side of the torso, with the axillary pad fitting the armpit;
2. Secure the torso straps: first fix the chest strap, then the waist strap, with tightness allowing one finger to be inserted comfortably;
3. Place the affected forearm into the elbow support, adjust the forearm support position so the elbow is flexed to approximately 90°;
4. Secure the forearm strap, taking care not to overtighten to avoid affecting blood circulation;
5. Finally, check the overall fit, observing the patient's comfort and any pressure points.
Generally, it should be worn throughout the day (including during sleep) for 4-6 consecutive weeks or as directed by a physician. Initial discomfort may occur, but persistent pressure or severe pain requires immediate consultation with a doctor. It may be removed for no more than 30 minutes daily (per physician's order) for skin cleaning and functional exercises.
During wear, the patient's unilateral upper limb movement is restricted, requiring assistance with activities such as dressing, bathing, and toileting. It is recommended to wear loose tops and prioritize the use of the unaffected hand. For bathing, a dedicated waterproof cover can be used or assistance from a rehabilitation nurse.
If the straps are too tight, they can cause skin redness and edema; if too loose, they cannot provide effective fixation. The fit is appropriate when the fingertip color is normal, there is no numbness or tingling, and one finger can be easily inserted under the strap. Check the skin daily; if any abnormality is found, adjust immediately or consult a doctor.
In case of local rash or blisters, temporarily loosen the straps, clean and dry the area, apply talcum powder, or use sterile dressings for protection. If there is ulceration or infection, discontinue use and seek medical attention. Routinely, every 2-3 hours, briefly release the straps under the guidance of a therapist to allow the skin to rest.
During the wearing period, active movement of the affected shoulder, elbow, and wrist is not recommended. However, exercises such as making a fist, small-range wrist flexion and extension (within pain-free limits), and strength training of the unaffected limb may be performed. The specific exercise plan should be developed by a rehabilitation physician.
When selecting, pay attention to the following points:
- Material breathability: The inner lining should be made of breathable mesh or cotton fabric to reduce stuffiness;
- Adjustable angles: The ratchet plate scale should be clear and lock firmly;
- Strap design: Velcro should be wide, easy to tear, and not prone to loosening;
- Ergonomics: The axillary pad and elbow support curves should fit well, avoiding sharp pressure points. It is recommended to try it on under professional guidance.
The outer fabric can be hand-washed with a mild detergent; do not machine wash. The inner lining (axillary pad, elbow support) can be removed for washing. The metal ratchet plate should avoid water; wipe it dry with a cloth after each use. After each use, place it in a ventilated area to dry in the shade, avoiding direct sunlight.
