A resting hand splint holds the whole hand in the POSITION OF SAFE IMMOBILIZATION:
- wrist tilted back,
- knuckles bent,
- finger joints straight,
- thumb held away from the palm
It’s used when the hand has to rest but must not stiffen in a bad position: after crush injuries, burns, severe swelling, hand infections, replantation, and during inflammatory arthritis flares.
It’s usually worn at night and between exercise sessions, rarely all day.
Why that exact position
- A swollen, painful hand drifts into the worst shape: wrist dropped, knuckles straight, finger joints bent, thumb pulled into the palm
- Knuckles bent keeps the ligaments at the sides of the knuckles at full length, so they can’t shorten
- Finger joints straight keeps the front of the middle joints from contracting into a permanent bend
- Thumb out keeps the web space open for gripping later
- Wrist back sets the tendon balance so the rest of the position holds
A swollen hand left to its own devices stiffens into a claw. The splint holds it in the shape you’ll need later.
What it’s used for
- Crush injuries with heavy swelling
- Burns, especially over the back of the hand, where scar pulls the knuckles straight
- Hand infections after surgical washout, such as tendon sheath infections
- After replantation and complex hand surgery, adapted to protect the repairs
- Rheumatoid arthritis flares, in a modified position that rests inflamed joints and supports drifting knuckles
- Neurological conditions, such as stroke, to manage tone and protect the hand
How to wear it
- At night, which is when swelling pools and joints settle into bad positions
- Between exercise sessions in the early weeks after a major injury
- Out for movement. The splint prevents stiffness at rest. Only movement actually restores range
- Hand raised above the heart when resting, to help swelling drain
A typical pattern after a crush injury
- Weeks 0 to 2: splint at night and between sessions. Gentle movement several times a day as the injury allows
- Weeks 2 to 6: night only, as swelling drops and movement improves
- After 6 weeks: usually stopped, unless a joint is losing range at night
Problems to watch for
- Straps too tight as swelling changes
- Pressure over the knuckles, wrist bones or burn grafts
- A splint that no longer matches the hand, because swelling has dropped or position has improved. It needs remolding
- Using it instead of exercising. Resting a hand in a perfect position still leaves it weak and stiff
Get it checked if
- Fingers pale, blue, cold or numb in the splint
- Marks that stay after 30 minutes out
- A fever, spreading redness or new pain after an infection or surgery
- Range getting worse despite wearing it
This is one of dozens of splints a hand therapist makes. See what a hand therapist does for the full list.
Rest the hand in the shape you want it to heal in, and move it every day.
