A to Z: Fracture, Radius

May also be called: Broken Arm

A fractured radius is a broken bone in the lower arm. It is a common injury in kids and teens that usually heals quickly.

More to Know

The radius is the bone on the thumb side between the elbow and wrist. Someone may fracture the distal (lower part) of the radius when holding out an arm to try to stop a fall.

Keep in Mind

Most of these fractures only require wearing a cast on the lower arm, although some breaks will need a long cast (above the elbow). Healing time varies, but a cast usually is worn for 4-6 weeks.
