The Bone Healed in Weeks. The Swelling Is Playing a Longer Game.
A wrist that’s still puffy 3 to 6 months after a fracture is common, and on its own it isn’t a sign something has gone wrong. Mild swelling can linger for up to a year, especially after plate surgery or in older adults.
It’s usually worst at the end of the day, after activity and in hot weather, and better in the morning. Month on month it should be shrinking, even when day to day it looks the same.
So the X-ray says healed. The cast is long gone. And by 6pm the wrist looks like it borrowed Popeye’s forearm. Rings stop at the knuckle. The watch strap leaves a dent. (That dent is a surprisingly honest swelling gauge, by the way.)
Here’s the part that matters more than how it looks. Swelling that sits in the hand for months doesn’t stay soft. It thickens, and it starts gluing tendons and joints in place. That’s how a fracture that healed well turns into a hand that won’t make a fist.
And a small number of swollen wrists are CRPS, where the first few months of treatment count the most.
So the useful questions are: is yours the normal kind, is it heading the right way, and what actually moves it out.
How long does swelling last after a wrist fracture?
A typical pattern, whether you had a cast or a plate. Your own surgeon’s timeline wins if it’s different.
- Weeks 0 to 6: swelling at its most, in the cast or splint. Finger movement and elevation matter most here. See the wrist fracture recovery timeline.
- Weeks 6 to 12: cast off. Swelling often goes UP for a couple of weeks as you start using the hand again, then starts to fall. This catches a lot of people off guard.
- Months 3 to 6: mainly end-of-day and after-activity puffiness. Mornings look close to normal.
- Months 6 to 12: a mild thickness may remain, especially after surgery or in older adults. Usually painless and more noticeable to you than to anyone else.
- After plate removal: a second, smaller round of swelling. Most of it settles over the first few weeks, with some puffiness for 2 to 3 months.
Why is my wrist still swollen when the bone has healed?
- Bone heals in weeks. Soft tissue settles in months. The fracture may be solid while the ligaments, tendon sheaths and capsule around it are still remodeling.
- Weeks in a cast switch off the muscle pump. Every time your fingers and forearm muscles squeeze, they push fluid back up the arm. Six weeks of not squeezing leaves a backlog.
- Gravity. An arm hanging by your side all day lets fluid pool in the hand, which is why rings get tight by evening.
- Surgery adds its own swelling around a plate and along the scar. See wrist fracture plate surgery recovery.
- Guarding. A wrist you’re protecting moves less, so it pumps less, so it stays puffy, so you protect it more. A loop that’s easy to get stuck in.
- Heat. Hot weather, long hot showers and heat packs open up the blood vessels and the hand fills up. Normal, and temporary.
Swelling that comes and goes with use is a wrist getting back to work. Swelling that brings color, heat and pain is a wrist asking for help.
Is swelling normal months after a broken wrist?
Usually expected:
- Better in the morning, worse by evening. The classic pattern of a healing wrist.
- Puffier after a busy day, gardening, cooking for a crowd or the gym, then settled by the next morning.
- A wrist that looks slightly thicker than the other one for months.
- Soft swelling that dents when you press it with a finger and slowly fills back in.
- Gradual improvement month on month, even if day to day it seems unchanged.
Not the normal kind:
- Burning pain out of proportion, with the hand shiny, blotchy, sweaty, hot or cold, and touch hard to bear. That’s the CRPS pattern (more below).
- Redness, heat and increasing pain over a scar, possibly with discharge or a fever. See wound healing or infection.
- The whole forearm and arm swelling, not just the wrist and hand.
- Swelling that’s getting worse after the first 6 weeks out of the cast instead of better.
- Swelling that has gone firm, no longer dents when you press it, with fingers that are getting stiffer.
How to reduce swelling after a wrist fracture
None of this is fancy. It works cos it’s done often, not cos it’s done hard.
- Elevated fist pumps. Raise the hand above your head, then make 10 slow full fists and 10 full finger stretches. Do it every hour you’re awake. This is the single most useful thing on this list.
- Elevate properly when resting. Hand higher than the elbow, elbow higher than the heart. On a cushion on your lap doesn’t count. At night, rest it on a pillow beside you.
- Retrograde massage. With the hand raised and a little lotion, stroke firmly from the fingertips toward the wrist, then from the wrist toward the elbow. Always one direction, toward the heart. About 5 minutes, 2 to 3 times a day. Skip it over an open or red scar.
- A light compression glove. Worn in the day, it helps a stubbornly puffy hand. It should feel snug, not tight. Take it off straight away if the fingers tingle, go numb, or turn white or blue. Most people don’t need it at night.
- Use the hand in normal daily tasks. Dressing, washing, typing, light cooking. Every grip is a pump. Guarding keeps the swelling around longer. Wrist exercises are in wrist fracture exercises after a cast.
- Cool, don’t cook, after a heavy day. A wrapped cold pack for 10 to 15 minutes with the hand raised. Go easy on heat packs and long hot showers if they leave you puffier.
- Rings and tight watches off until the swelling has settled. A ring stuck on a swelling finger is its own emergency.

How do I know if it’s getting better?
Day to day you can’t tell. Your eyes adjust. So measure.
- Tape measure: around the wrist at the crease and around the knuckles, both hands, same time of evening, once a week. Write it down.
- The ring test: how far does a ring go on that finger, morning and evening?
- A photo: both hands side by side, same angle, once a month.
The trend is what counts. Shrinking month on month is healing, however slowly. Flat for 6 to 8 weeks, or growing, is worth a review.
The swelling isn’t on a clock. The stiffness is.
Mild swelling on its own has time on its side. It will usually settle.
The stiffness it causes is different. Swelling fluid is protein-rich. Left sitting for weeks, it organizes into scar-like tissue that tethers tendons and tightens joint capsules. The window where fingers and wrist respond best to exercise and splinting is roughly the first 3 months after the cast comes off. After 6 months, the same stiffness takes far longer to shift.
- Check this today: can you make a full fist, fingertips touching the palm? Can you straighten every finger fully?
- If not, and it’s not improving week on week, that’s the problem to fix now, before the swelling. See stiff hand after a cast or surgery.
- Still aching as well as swelling a year on? That’s a different conversation. See wrist still hurts a year after a fracture.
When swelling means CRPS
Complex regional pain syndrome is uncommon, but wrist fractures are one of the classic triggers. It usually shows up in the first weeks to months, often while still in the cast or soon after.
- Pain out of proportion to the injury, often burning, and getting worse instead of better.
- Skin changes: shiny, blotchy, red or purple, hotter or colder than the other hand, sweating more or less.
- Touch hurts. A sleeve, a bedsheet, a light brush is hard to bear.
- Hair or nails growing faster or slower on that hand, and stiffness that’s racing ahead.
If that’s you, see your doctor this week and say the word CRPS out loud. Early graded movement, desensitization and pain management give the best chance. Waiting it out is the wrong strategy for this one. Full details in CRPS in the hand and wrist.
Swelling around the plate: hardware irritation
A plate sits close to tendons. Most people never feel it. Some do.
- Signs it’s the plate: swelling and tenderness in one spot over the plate or a screw head, aching or catching when you move the thumb or fingers, and a wrist that’s otherwise improving.
- What usually happens: activity adjustment and therapy first. If it keeps bothering you once the fracture is solid, plate removal is a common, smaller operation. Your surgeon decides when.
- The one not to sit on: a thumb that suddenly can’t lift up off the table. A tendon may have frayed through. That needs your surgeon quickly.
What a hand therapist does for a swollen wrist
- Measures it, so you both know whether it’s actually improving.
- Sorts the kind of swelling: normal healing, stiffness-driving, plate-related or CRPS-pattern. Each one is handled differently.
- Specific edema techniques, such as manual edema mobilization and correctly fitted compression garments.
- Targets the stiffness the swelling left behind: tendon gliding, joint mobilization, and splints that stretch a joint for hours at a time when exercises alone aren’t enough.
Get it checked today if
- The scar is red, hot and discharging, or you have a fever.
- The whole arm suddenly swells, feels heavy, or looks bluish.
- The fingers go numb, white or cold. If you’re wearing a compression glove, take it off first.
- Burning pain with color, temperature or sweating changes in the hand.
- You suddenly can’t lift the thumb off a table.
Get it checked if
- Swelling is getting worse after the first 6 weeks out of the cast, instead of better.
- Your measurements haven’t moved in 6 to 8 weeks.
- You can’t make a full fist by 3 months, or stiffness is getting worse.
- One spot over the plate stays swollen and tender, or something catches when you move.
Puffy by evening and better by morning is healing. Hot, blotchy and painful needs a same-week review.
Written by Nigel Chua, hand occupational therapist in practice since 2005. Thousands of hands, wrists and elbows assessed and treated. My credentials are here. This article explains; it doesn’t examine. A swollen wrist that’s getting stiffer, hotter or more painful deserves a review this week.
