Your Wrist Healed. So Why Won’t Your Palm Turn Up?
Turning the palm up is one of the movements most often lost after a wrist fracture. For most people it comes back with daily exercises, and the biggest gains happen between weeks 6 and 12, the first 6 weeks after the cast or splint comes off.
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. That’s worth a review, not more waiting.
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
- Turn a key
Palm-up is literally the “show me the money” position. (Jerry Maguire never had to do it with a stiff forearm.)
Here’s what goes wrong. People assume rotation will loosen up by itself, like a door hinge that needs oiling. They wait. By month 4 or 5 the tissue between the forearm bones has spent months settling palm-down, and the easy gains are behind them.
So let’s sort out which kind of stiff you have, what to do about it, and when to stop doing it alone.
Why can’t I turn my palm up after a broken wrist?
- Turning the palm up and down happens as the radius rolls around the ulna, at joints near both the wrist and the elbow. The wrist fracture sits right at the bottom of that hinge.
- 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.
- The fracture itself can heal slightly short or tilted, which changes how the two bones meet when they rotate.
Palm-UP (supination, if your report uses the word) usually comes back slower than palm-down. Daily life keeps you palm-down at keyboards, steering wheels and tables, so palm-down gets practiced for free. Palm-up only comes back if you ask for it.
Is it normal to not be able to turn my palm up after a cast?
Yes, early on. Straight out of a 6-week cast, most people can turn the palm up only part of the way, and it feels tight, achy and a little wrong. That’s expected.
For reference, most daily tasks need roughly 50 degrees of palm-up turning. A normal forearm has more than that, so you don’t need perfection to function well. But you do need more than you probably have at week 6.
- Usually expected: a slow, springy stop that eases a few degrees with a sustained hold, and a bit more range each week.
- Worth checking: a hard, sudden stop with no give, a painful clunk on the little-finger side, or range that’s going BACKWARDS.
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.
How to check your palm-up turning at home
- 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.
- Check once a week, same chair, same time of day. A photo from above makes the comparison honest.
How a hand therapist works out what’s limiting it
Two people can both “not turn the palm up” for completely different reasons. What I’m checking for:
- The end-feel. Springy and stretchy points to tight soft tissue. Hard and abrupt points to bone or joint.
- Active versus assisted range. If I can turn it further than you can, the muscles are weak or guarding. If neither of us can, the joint is the limit.
- Where it hurts. Little-finger side pain with turning raises the TFCC or the joint between the forearm bones. See TFCC injury.
- The elbow. If a long arm cast held the elbow still, part of the stiffness lives up there.
- Imaging, when the feel says bone. An X-ray checks the angle and length the fracture healed at. A CT scan shows the joint between the forearm bones in more detail.
Exercises to get your palm-up turning back
Your surgeon or therapist may give you a different program. Use theirs. If you had a plate, see wrist fracture plate rehab for when movement usually starts.
- Active palm-up turns: elbow at your side, turn slowly palm-up, hold the end for 5 seconds, then palm-down. 10 reps, every 2 to 3 hours while awake.
- Assisted stretch: use the other hand to ease the palm further up, hold 20 to 30 seconds. 3 to 5 reps, 3 to 4 times a day. A stretch, not a fight.
- Use a lever: hold a hammer or a small weighted stick near one end and let gravity add a gentle stretch at the end of the turn. Hold 30 seconds, 3 reps. The further you hold from the head, the stronger the pull.
- Warm first, stretch second. A few minutes with the forearm in warm water makes the tissue more willing.
- Work the elbow too if a long arm cast held it still: full bend and full straighten, 10 reps, a few times a day.
- Use it in real life. Carry your plate palm-up. Take your change palm-up. Fifty small asks a day beat one heroic session.
For the full set after the cast, see wrist fracture exercises.
Splints for stubborn cases. If gains stall, a static progressive splint or a dynamic splint holds a low, sustained stretch for longer periods. Tissue responds to TIME at a gentle stretch far better than to a few hard pushes.
How long does it take to turn your palm up again after a wrist fracture?
This is the window your forearm rotation runs on. It is OPEN for the first few months, it closes slowly, and you want to do your hard work while it’s wide open.
- Weeks 0 to 6 (cast or splint): rotation limited or blocked. Keep fingers, elbow and shoulder moving.
- Weeks 6 to 12 (window OPEN): the biggest gains, with daily exercises. This is the stretch that matters most.
- Months 3 to 6 (window CLOSING): slower gains. Splinting is added if progress stalls. A review is sensible if you’re under half of the other side.
- After 6 months (mostly SHUT for exercise alone): usually close to a plateau. Remaining limits are less likely to change with exercise alone, and the conversation shifts to splints, injections or surgery.
Can I drive or work if I can’t turn my palm up?
- Driving: you need enough rotation and grip to turn the wheel hand-over-hand in an emergency, not just cruise on a straight highway. For most people that’s a while after the cast comes off, not the day it does. Your surgeon and your insurer get the final say. See driving after a hand injury.
- Desk work: usually fine early, cos typing is palm-down. Phones held to the ear and mice that tilt the hand need more rotation than you’d think.
- Hospitality, retail, trades: carrying trays, handing over goods, using a screwdriver. These ask for palm-up all day, and they usually wait until rotation and strength are both back, often around 3 months.
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. See clicking and clunking after a wrist fracture.
- 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. That’s a conversation with a hand surgeon, and it goes better with your weekly measurements in hand.
Get it checked today if
- Your fingers are getting more numb, or the numbness is spreading.
- Pain and swelling are getting worse, with shiny, color-changed, very sensitive skin.
- You’ve had a new fall or twist and rotation suddenly got much worse, with a clunk.
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.
