This injury is caused by trauma from:
- Fall on an outstretched hand
- Direct blow to the forearm
- An object in the air that hits the forearm
- A motor vehicle accident
Things that may raise the risk of this injury are:
- Playing contact sports
- Health problems that weaken bones, such as osteoporosis
- Health problems that result in falls, such as weak muscles
A forearm fracture may cause:
- Pain that is worse when moving the arm
- Swelling and bruising
- Problems moving the arm
- A change in the way the arm looks
The doctor will ask about your symptoms and health history. You will be asked how the injury happened. An exam will be done that focuses on your arm.
Images may be taken of the arm. This can be done with:
How it is treated depends on whether the injury is mild or severe. Options may be:
Initial care may be:
- Ice to ease pain and swelling
- Medicine to ease pain
- A splint, brace, cast, or sling to keep the bones of the arm in place as it heals
- Exercises to help with strength and motion
Children's bones have growth plates that let bones grow and harden with age. A child with this type of fracture will need to be checked over time to make sure the bone heals the right way and keeps growing.
Putting Bones Back In Place
Some fractures cause pieces of bone to come apart. These pieces will need to be put back into place. This may be done:
- Without surgery—anesthesia will be used to ease pain while the doctor moves the pieces back into place
- With surgery—pins, screws, plates, or wires may be used to reconnect the pieces and hold them in place
Most fractures are due to accidents. Healthy bones and muscles may prevent injury. This may be done through diet and exercise.
