Broken Forearm | Testing & Diagnosis

How are broken forearms in children diagnosed?

To diagnose broken forearms in children, the doctor will carefully examine the injured area for tenderness, redness and swelling.

One or more of the following imaging techniques may also be used to get detailed pictures of the broken bone and to check for damage to muscles or blood vessels.


An x-ray of the arm is the main tool used for diagnosing a broken bone. This painless test uses small amounts of radiation to produce images of bone onto film. After the doctor puts the pieces of the broken bone in the right position, an x-ray can also help determine whether the bones in the arm are healing in the proper position.

Magnetic resonance imaging (MRI)

An MRI is a diagnostic procedure that uses a combination of large magnets, radiofrequencies, and a computer to produce detailed images of organs and structures within the body. These types of tests are more sensitive than x-rays and can pick up smaller fractures before they get worse.

Computed tomography scan (CT, CAT scan)

A diagnostic imaging procedure that uses a combination of x-rays and computer technology to produce cross-sectional images (often called slices), both horizontally and vertically, of the body.
