A scaphoid wrist fracture is a crack or break in the bone called the navicular or scaphoid bone. This bone, near the thumb, is 1 of the 8 bones in the wrist. The break may be just a small crack in the bone, or the bone may break into pieces or shatter.
A scaphoid fracture is the most common type of wrist fracture.
What is the cause?
A scaphoid fracture is usually caused by falling onto your outstretched hand or a direct hit to the wrist. A fracture may also be the result of a medical condition that causes weak or brittle bones.
What are the symptoms?
Symptoms may include:
Pain, swelling, bruising, or tenderness that happens right after the injury, usually just below the thumb
Pain when the injured area is touched
Pain or swelling that keeps you from bending or using your wrist
An area of the wrist or hand that is cold, pale, or numb
A change in the shape of the wrist
How is it diagnosed?
Your healthcare provider will ask about your symptoms and how the injury happened. Your provider will examine you. Tests may include:
X-rays of the wrist
CT scan, which uses X-rays and a computer to show detailed pictures of the bones
MRI, which uses a strong magnetic field and radio waves to show detailed pictures of the bones
How is it treated?
The treatment depends on the type of fracture.
If you have an open wound with the fracture, you may need treatment to control bleeding or prevent infection.
Your healthcare provider will usually put your arm and wrist in a cast that includes your thumb to keep your wrist from moving while it heals. If you have a cast, make sure the cast does not get wet. Cover the cast with plastic when you bathe. Avoid scratching the skin around the cast or poking things down between the cast and your skin. This could cause an infection.
You may need surgery to put the bones back into the right position or a bone graft to make the joint stronger.
With treatment, the fracture may take up to 3 months to heal. You may need to do special exercises to help your wrist get stronger and more flexible. Ask your healthcare provider about this.
How can I take care of myself?
Follow the full course of treatment your healthcare provider prescribes. Also:
To keep swelling down and help relieve pain, your healthcare provider may tell you to:
Put an ice pack, gel pack, or package of frozen vegetables wrapped in a cloth on the injured area every 3 to 4 hours for up to 20 minutes at a time for the first day or two after the injury.
Keep the wrist up on pillows when you sit or lie down. Your provider may also recommend using a sling to keep the hand up while you do your daily activities.
Take pain medicine, such as ibuprofen, as directed by your provider. Nonsteroidal anti-inflammatory medicines (NSAIDs), such as ibuprofen, may cause stomach bleeding and other problems. These risks increase with age. Read the label and take as directed. Unless recommended by your healthcare provider, you should not take this medicine for more than 10 days.
Ask your healthcare provider:
How and when you will hear your test results
How long it will take to recover
What activities you should avoid and when you can return to your normal activities
How to take care of yourself at home
What symptoms or problems you should watch for and what to do if you have them
Make sure you know when you should come back for a checkup.
How can I help prevent a scaphoid fracture?
Most broken wrists are caused by accidents that are not easy to prevent. When you do activities like skating, be sure to wear protective wrist guards.
