Most Wrist Fractures Heals in 6 Weeks. How Well Recovery Is Decided in Weeks 6 to 12.
A distal radius fracture, the classic broken wrist from a fall onto an outstretched hand, is the fracture I rehabilitate more than any other.
And here’s the thing nobody tells you at the hospital: the bone healing is the easy part.
Cast or surgical plate, the fracture itself usually knits in about 6 weeks. What comes out of that cast is a wrist that’s stiff, weak, swollen, and honestly…a little scared of the world.
Weeks 6 to 12 are where your final outcome is actually decided. And they’re exactly the weeks many people get discharged into with a photocopied exercise sheet and a “good luck”.
What’s actually happening in there
Our radial bone (radius) is the larger bone of your two forearm bones, and its last few centimetres carry most of the load every time you push, press or catch yourself. Fall on an outstretched hand (FOOSH), and that’s the segment that breaks.
That’s why the term “distal radial fractures” are quite commonplace (and one of my most-treated conditions in my entire professional hand occupational therapy career).
Two treatment routes, decided by how the broken pieces sit.
- IF Pieces in good position: a cast holds them there while bone bridges the gap.
- IF Pieces displaced, tilted or in fragments: surgery with a plate and screws puts the architecture back, cos a wrist that heals tilted trades away its mechanics permanently.
Either way, while the fractured wrist bone heals, everything around it needs to pay rent. You see, all human joints stiffen in the cast position. Muscles shrink from disuse, noticeably, from day 1, and compounds. The shoulder and elbow of that arm often stiffen too, cos the whole limb stops being used or moving (most people guard their entire hand too much, though I understand why).
And swelling that sits in the hand can stiffen fingers that were never even broken…and more often than not, secondary stiffness can be worse to handle than the fracture rehab itself. I’m serious.
Which is why good rehab actually starts IN the cast: keeping the fingers, elbow and shoulder moving from week one. The wrist rests. Nothing else should.
The honest timeline
- Weeks 0 to 6, protection phase: the bone knits. Your job is swelling control (elevation, moving the fingers often) and keeping every joint that isn’t fractured moving daily. Fingers that pump regularly come out of the cast working. Fingers that sat still and minimal movement will definitely come out stiff…a second problem you didn’t need.
- Weeks 6 to 12, the deciding phase: cast off, and the real work starts. We gotta work on the double to win back wrist movements – bending, straightening and rotation before stiffness consolidates further, then when ready, start and gradually reintroducing load. This window matters because soft tissue that stays stiff past about 3 months becomes progressively harder to change. Early stiffness is wet cement. Old stiffness is set concrete.
- Months 3 to 6 and beyond: strength and confidence. Grip strength rebuilds over months, not weeks. Pushing up from a chair, carrying groceries, downward dog…each returns in order as the wrist proves itself. Aches after heavy days during this period are normal and fading, not a sign of damage.
Full function takes months.
That’s normal, not a sign something went wrong. A wrist at month 4 that’s still building strength is on schedule…nobody tells people this, so they quietly panic at month 3.
The signs you’re drifting off course
Some things during recovery are NOT normal, and each one is a get-reviewed-now flag:
Fingers becoming stiffer, more swollen and more painful over time instead of less, with increasingly shiny skin…that pattern needs urgent review, cos a small group of wrist fractures develop a pain condition (CRPS) where early treatment matters enormously.
New numbness or tingling in the thumb, index and middle fingers…the swelling may be compressing the median nerve, carpal-tunnel style.
And months down the road, if you develop a sudden inability to lift the thumb up and out…a specific thumb tendon can fray and snap over the healed fracture site. Rare, but it’s a same-week review, not a wait-and-see.
What good rehab actually looks like
Weeks 6 to 8: gentle, frequent motion work in all directions, short sessions many times a day beating one heroic session. Swelling management continues. Light functional use returns…cutlery, keyboards, washing your own hair with that hand.
Weeks 8 to 12: progressive strengthening begins once motion is trending well. Grip work, wrist loading, rotation under resistance. This is graded, planned loading…not “use it and see”.
The cast protected the bone. The rehab protects the next 30 years of that wrist.
And through all of it, the question I ask patients to track: what can this wrist do this week that it couldn’t do last week? Recovery that’s progressing answers that question every single week. Recovery that’s stalled for 2 to 3 weeks straight needs a plan change, not more patience.
The short version
Your wrist fracture will very likely heal fine. Whether your WRIST ends up fine is a separate question, answered mostly between weeks 6 and 12.
Move everything that isn’t broken from week one. Treat the cast coming off as the start of the project, not the end. And if you were handed an exercise sheet and nothing else, get proper hand therapy for that 6-to-12 window…it’s the highest-leverage 6 weeks of the entire recovery.
