A broken wrist is a break or crack in one or more of the bones of your wrist. The most common of these injuries occurs in the wrist when people try to catch themselves during a fall and land hard on an outstretched hand.
You may be at higher risk of a broken wrist if you participate in sports like in-line skating or snowboarding, or if you have a condition in which bones become thinner and more fragile (osteoporosis).
It's important to treat a broken wrist as soon as possible. Otherwise, the bones might not heal in proper alignment, which might affect your ability to do everyday activities, such as writing or buttoning a shirt. Early treatment will also help minimize pain and stiffness.
Your wrist is made up of eight small bones (carpal bones) plus two long bones in your forearm — the radius and the ulna. The most commonly injured carpal bone is the scaphoid bone, located near the base of your thumb.
The distal radius fracture is one of the most common fractures of the wrist. It usually occurs when people fall on an outstretched hand.
A broken wrist might cause these signs and symptoms:
- Severe pain that might worsen when gripping or squeezing or moving your hand or wrist
- Obvious deformity, such as a bent wrist
When to call a doctor
If you think you might have a broken wrist, see a doctor immediately, especially if you have numbness, swelling or trouble moving your fingers. A delay in diagnosis and treatment can lead to poor healing, decreased range of motion and decreased grip strength.
A broken wrist can be caused by:
- Falls. Falling onto an outstretched hand is one of the most common causes of a broken wrist.
- Sports injuries. Many wrist fractures occur during contact sports or sports in which you might fall onto an outstretched hand — such as in-line skating or snowboarding.
- Motor vehicle crashes. Motor vehicle crashes can cause wrist bones to break, sometimes into many pieces, and often require surgical repair.
Participating in certain sports activities and having the bone-thinning disease osteoporosis can increase your chances of breaking a wrist.
Contact sports and activities that increase your risk of falling can increase your risk of breaking bones in your wrist. Examples include:
- Football or soccer, especially on artificial turf
- Horseback riding
- In-line skating
- Jumping on a trampoline
Complications of a broken wrist are rare, but they might include:
- Ongoing stiffness, aching or disability. Stiffness, pain or aching in the affected area generally goes away eventually after your cast is removed or after surgery. However, some people have permanent stiffness or pain. Be patient with your recovery, and talk to your doctor about exercises that might help or for a referral to physical or occupational therapy.
- Osteoarthritis. Fractures that extend into a joint can cause arthritis years later. If your wrist starts to hurt or swell long after a break, see your doctor for an evaluation.
- Nerve or blood vessel damage. Trauma to the wrist can injure adjacent nerves and blood vessels. Seek immediate attention if you have numbness or circulation problems.
It's impossible to prevent the unforeseen events that often cause a broken wrist. But these tips might offer some protection.
Build bone strength
To build strong bones:
- Eat a nutritious diet with adequate calcium and vitamin D
- Get plenty of weight-bearing exercise, such as brisk walking
- Quit smoking if you're a smoker
Most broken wrists occur when people fall forward onto an outstretched hand. To prevent this common injury:
- Wear sensible shoes
- Remove things you can trip over in your home, such as throw rugs
- Light up your living space
- Have your vision checked and, if needed, corrected
- Install grab bars in your bathroom
- Install handrails on your stairways
- Avoid slippery surfaces, if possible, such as snow- or ice-covered walkways
Use protective gear for athletic activities
Wear wrist guards for high-risk activities, such as:
- In-line skating
The diagnosis of a broken wrist generally includes a physical exam of the affected hand and X-rays.
Other imaging tests
Sometimes, other imaging tests can give your doctor more detail. They are:
- CT scan. CT scans can uncover wrist fractures that X-rays miss. Injuries to soft tissues and blood vessels can be seen on CT scans. This technology takes X-rays from a variety of angles and combines them to depict cross-sectional slices of your body's internal structures.
- MRI. Using radio waves and a powerful magnet to produce detailed images of bone and soft tissues, MRIs are much more sensitive than X-rays and can identify very small fractures and ligament injuries.
If the broken ends of the bone aren't aligned properly, there can be gaps between the pieces of bone or fragments might overlap. Your doctor will need to manipulate the pieces back into position, a procedure known as a reduction. Depending on the amount of pain and swelling you have, you might need a local or general anesthetic before this procedure.
Whatever your treatment, it's important to move your fingers regularly while the fracture is healing to keep them from stiffening. Ask your doctor about the best ways to move them. If you smoke, quit. Smoking can delay or prevent bone healing.
Restricting the movement of a broken bone in your wrist is critical to proper healing. To do this, you'll likely need a splint or a cast. You'll be advised to keep your hand above heart level as much as possible to reduce swelling and pain.
To reduce pain, your doctor might recommend an over-the-counter pain reliever. If your pain is severe, you might need an opioid medication, such as codeine.
NSAIDs can help with pain but might also hamper bone healing, especially if used long-term. Ask your doctor if you can take them for pain relief.
If you have an open fracture, in which you have a wound or break in the skin near the wound site, you'll likely be given an antibiotic to prevent infection that could reach the bone.
After your cast or splint is removed, you'll likely need rehabilitation exercises or physical therapy to reduce stiffness and restore movement in your wrist. Rehabilitation can help, but it can take several months or longer for complete healing.
Surgical and other procedures
You might need surgery to implant pins, plates, rods or screws to hold your bones in place while they heal. A bone graft might be used to help healing. These options might be necessary if you have:
- An open fracture
- A fracture in which the bone pieces move before they heal
- Loose bone fragments that could enter a joint
- Damage to the surrounding ligaments, nerves or blood vessels
- Fractures that extend into a joint
Even after reduction and immobilization with a cast or splint, your bones can shift. So your doctor likely will monitor your progress with X-rays. If your bones move, you might then need surgery.
In some cases, the surgeon will immobilize your fracture by using an external fixation device. This consists of a metal frame with two or more pins that go through your skin and into the bone on both sides of the fracture.
With external fixation, a metal frame outside your body immobilizes the fracture with two or more pins that pass through your skin and into the bone on either side of the fracture.
Preparing for an appointment
You might first seek treatment for a broken wrist in an emergency room or urgent care clinic. If the pieces of broken bone aren't lined up properly to allow healing with immobilization, you might be referred to a doctor specializing in orthopedic surgery.
What you can do
You may want to note down the following information:
- A description of your symptoms and how, where and when the injury occurred
- Information about your and your family's medical histories
- All the medications and dietary supplements you take, including doses
- Questions you want to ask the doctor
For a broken wrist, questions to ask your doctor include:
- What tests do I need?
- What's the best course of action?
- Will I need surgery?
- Will I need to wear a cast? If so, for how long?
- Will I need physical therapy when the cast comes off?
- Are there restrictions that I need to follow?
- Should I see a specialist?
What to expect from your doctor
Your doctor might ask:
- What is your occupation?
- Was your wrist bent backward or forward when the impact occurred?
- Are you right-handed or left-handed?
- Where does it hurt, and do certain movements make it hurt more or less?
- Have you had previous wrist injuries or surgery?
