A buckle fracture is a unique type of fracture that most often occurs in children. It is a compression fracture on one side of a bone that causes the bone to bend or buckle toward the damaged side. Buckle fractures are more common in children because their bones are softer and more able to bend.
Buckle fractures of the forearm usually occur in the radius. The radius is the bone that runs along the thumb side of the arm forming most of the wrist joint.

Most buckle fractures are the result of falling on an outstretched arm.
Some buckle fractures may also occur with a direct blow to the forearm or wrist.
Certain health conditions, such as tumors or vitamin D deficiency, can weaken bones.
Other factors that may increase your child’s chance of a buckle fracture include:
Buckle fractures may cause forearm or wrist pain, with or without swelling. Other symptoms may include:
The doctor will ask about your child’s symptoms, medical history, and activities at the time of injury. The doctor will examine the wrist and forearm. If your child fell, the doctor may suspect a fracture.
Imaging tests to assess the fracture may include:
A cast or splint will be used to help make sure the bone stays in the correct position while healing. Without immobilization, the bone will heal, but it may heal incorrectly, which can cause later problems with movement.
Buckle fractures rarely result in complications or surgery.
Swelling and pain can be managed with over the counter or prescription pain medications.
It may take up to 4 weeks for a buckle fracture to fully heal.
Some physical activities will need to be adjusted so the bone can properly heal. Ice and elevating your arm at rest may also be advised to help with swelling and pain.
When your child is ready, exercises may be advised to reduce stiffness and improve range-of-motion. Your child should not return to activities or sports until their doctor gives them permission to do so.
