A broken wrist is the fracture of any bone in your wrist.
- A broken wrist is usually due to falling on to an outstretched hand.
- Common symptoms of a broken wrist include severe pain, swelling or bruising, tingling or numbness of your hands or fingers, and difficulty moving your hands.
- The most common way to diagnose a broken wrist is by an x-ray. However a wrist fracture can sometimes be difficult to see on an x-ray.
- Treatment aims to put the broken bones back together so the bone can heal properly and you get back normal movement of your wrist.
- For minor breaks, you will need to wear a cast or splint. Major breaks may require surgery.
What are the causes of a broken wrist?
Your wrist joint is made up of several bones. These include the 8 carpal bones, the radius and the ulna. Any of these bones can break. However, the more common wrist fractures include:
- distal radius and ulna fracture
- scaphoid (one of the carpal bones) fracture.
The cause of a broken wrist is usually due to a fall on to an outstretched hand. Other causes include:
- serious accidents such as motor vehicle accidents
- a break that occurs in a weak bone, such as if you have osteoporosis.

How is a broken wrist diagnosed?
If you think you may have a broken wrist, you should see a doctor straight away.
Your doctor will assess your general condition, as well as the seriousness of your injury. They will ask about how the injury happened, any symptoms and your medical background.
The most common way to diagnose a fracture is by an x-ray. These show the type of break and its location within the bone. Sometimes, a wrist fracture is hard to see on an x-ray. In that case, you may get a repeat x-ray after a week or more, or have a CT scan or MRI scan, depending on what the doctor thinks is most useful.
How is a broken wrist treated?
Treatment of a broken wrist aims to put the broken bones back together so that the bone can heal properly and you get normal movement of your wrist back.
The treatment you receive depends on how bad the break is. Other factors that affect your treatment include:
- the type of fracture
- your age
- whether the bones have moved or been displaced
- whether the bones break through your skin
- the number of bone fragments from the fracture
- your job or usual activities.
If you have a minor fracture, you will usually be treated with a cast or splint to hold your bones together and support your wrist while it heals.
If you have a more serious fracture, your doctor will try to realign the bones together, either manually using hands or through surgery to insert pins, plates or screws to hold your bones in place.
In both cases you will be given painkillers and be advised on the care following treatment. This may involve physiotherapy or hand therapy.
What is the outlook for someone with a broken wrist?
You will need to wear a cast until the bones heal. This will usually take 4–6 weeks, or longer if the fracture is more serious.
Sometimes after the cast comes off it may be useful to wear a splint some of the time, so that you feel comfortable and confident to use your hand again, but a splint is not always necessary.
If you have had surgery and the bones are well fixed with a plate and/or screw(s), you might only have the cast on for 10–14 days. After that you may wear a splint for some or all the time for 3–4 weeks, but you can start moving your wrist, usually under the guidance of your surgeon and/or physiotherapist or hand therapist.
Do not expect your hand and wrist to be normal as soon as the cast comes off. Eventually, your hand and wrist will work well again, but it will take time.
How can I care for myself with a broken wrist?
There are several self-care measures that you can do to help the recovery of your broken wrist. These include:
- taking regular pain killers if you have any pain
- keeping your arm elevated on a pillow or with a sling in the first week, but after that start to let your arm be part of your everyday life again
- doing gentle exercises as advised by your health providers
- avoiding heavy lifting or activities that require your wrist to work hard
- positioning your arm with your thumb up rather than letting your arm rest with the palm down all the time as this will help lessen stiffness later
- keeping your cast dry
- stopping smoking.

After your cast is removed, you may find your wrist is stiff, your skin dry or your hand swollen. It may take 4 months to 1 year to regain full use of your hand and wrist. Your recovery will be helped by using your hand as normally as possible for everyday activities and by doing any exercises your doctor recommends.
