Turning the palm up is one of the movements most often lost after a wrist fracture, and for most people it comes back with daily exercises over the first three months.
This ability may sound mild…but you know, it matters more than it sounds – you need it to
- receive change or stuff in your hand
- carry a plate
- steer a car
- wash your face and
- turn a key
If it’s still badly limited at three months, or stops at a hard, sudden block rather than a slow stretch, the cause may be in the joint between the forearm bones or in how the fracture healed, and it’s worth a review.
Why this movement goes first
- Turning the palm up and down happens as the radius rolls around the ulna, at joints near both the wrist and the elbow. See wrist anatomy
- Casts and swelling hold the forearm palm-down for weeks, and the joint capsule and the membrane between the two bones tighten in that position
- Some casts and splints deliberately block rotation for a few weeks. See sugar tong and Muenster splints
- The joint between the forearm bones at the wrist, and the TFCC that stabilizes it, can be injured in the same fall
A slow, springy stop usually means stiffness that exercise can stretch. A hard, sudden block needs someone to find out what’s in the way.
Check it yourself
- Sit with your elbow tucked against your side and bent to a right angle
- Hold a pen in your fist, pointing forward
- Turn the palm up as far as you can. Compare the angle of the pen with the other side
- Keep the elbow against your side. Letting it drift out is how the shoulder cheats
What helps
- Little and often: slow palm-up turns, held at the end for 20 to 30 seconds, several times a day. See wrist fracture exercises
- Use a lever: holding a hammer or a small weighted stick near one end lets gravity add a gentle stretch
- Warm first, stretch second
- Work the elbow too if a long arm cast held it still
- Splints for stubborn cases: a static progressive splint or dynamic splint that holds a low, sustained stretch for longer periods
A typical pattern
- Weeks 0 to 6: in the cast or splint. Rotation limited or blocked
- Weeks 6 to 12: the biggest gains, with daily exercises
- Months 3 to 6: slower gains. Splinting added if progress stalls
- After 6 months: usually close to a plateau. Remaining limits are less likely to change with exercise alone
When it may be more than stiffness
- The fracture healed at an angle or shortened, changing how the forearm bones meet. See forearm fracture recovery
- Pain and clicking on the little-finger side with rotation: a TFCC injury or forearm joint problem
- A hard block with no give at the end
- Rotation getting worse rather than better
These usually need an X-ray or CT scan to look at alignment. Surgery is occasionally needed to release a tight joint or correct how the bone healed.
Get it checked if
- Palm-up turning is less than half of the other side at three months
- The movement stops at a hard, painful block
- There’s a clunk or pain on the little-finger side when turning
- Progress has stopped for a month despite daily exercises
Turn the palm up little and often for three months. If it hits a wall, get it scanned.
