Description

Indication for Use

1. De Quervain’s Tenosynovitis

Inflammation of the tendons around the base of the thumb. The splint immobilizes the thumb and wrist to reduce pain and promote healing.

2. Thumb Sprains or Strains

Provides stabilization following ligament injuries, such as a sprain of the ulnar collateral ligament (UCL) of the thumb, often referred to as "skier's thumb."

3. Scaphoid Fractures

Used in cases of scaphoid (carpal bone) fractures to immobilize the wrist and thumb for proper healing.

4. Thumb Arthritis

Beneficial for patients with osteoarthritis or rheumatoid arthritis affecting the thumb's carpometacarpal (CMC) joint. It helps relieve pain and provides support during activities.

5. Post-Surgical or Post-Injury Immobilization

Used after thumb-related surgeries or injuries to protect the area during the recovery phase.

6. Tendon Injuries

Immobilizes the thumb to aid in the healing of tendon injuries or inflammation, such as extensor or flexor tendon injuries.

7. Trigger Thumb

Helps reduce movement and irritation in cases of stenosing tenosynovitis (trigger thumb).

8. Gamekeeper's Thumb

Stabilizes the thumb following chronic UCL injury from repetitive stress or strain.

9. Wrist and Thumb Pain from Overuse

Provides rest and support for conditions resulting from repetitive motions, such as in sports or occupational tasks.

10. Hand Fractures

May be used as part of the management for specific metacarpal fractures, particularly the base of the first metacarpal.

11. Soft Tissue Injuries

Immobilizes the thumb and wrist to allow soft tissue injuries to heal without further stress.

Application

1. Preparation

Select the appropriate size and type of splint (prefabricated or custom-made) based on the condition being treated. Ensure the splint is clean and in good condition. Have medical tape, straps, or Velcro ready if needed for fastening.

2. Positioning the Hand

The wrist and thumb should be in a neutral, relaxed position. The thumb should be slightly abducted (away from the palm) and aligned with the rest of the hand. The wrist should be in slight extension (approximately 10–15 degrees) if immobilization includes the wrist.

3. Placing the Splint

Prefabricated Splint:

Slide or position the splint onto the hand so the thumb is comfortably secured in the thumb pocket or strap. Align the splint to cover the wrist, thumb, and the base of the hand appropriately.

Custom-Molded Splint (if applicable):

Mold the splint material to fit the contours of the wrist and thumb. Ensure a snug fit without restricting blood flow or causing discomfort.

4. Securing the Splint

Fasten the straps or Velcro closures firmly but comfortably. Ensure the thumb and wrist are immobilized while allowing free movement of the other fingers. Avoid overtightening, which can cause discomfort or impede circulation.

5. Checking Fit and Comfort

Ensure there is no excessive pressure on bony prominences (e.g., the base of the thumb or wrist). Verify that the patient can feel their fingers and that blood circulation is not compromised (fingers should not turn pale or blue).
