What is a Pediatric Distal Radius Fracture?
A pediatric distal radius fracture is a break in the distal (wrist-end) portion of the radius bone in a child’s forearm. The radius is one of the two bones in the forearm and helps form the wrist joint. This type of fracture is very common in children because their bones are still growing and more flexible than adult bones. Most fractures heal well with proper treatment due to the strong healing ability of pediatric bones.
What are the Common Types of Pediatric Distal Radius Fractures?
Common types of pediatric distal radius fractures include the following:
- Buckle (Torus) Fracture: A compression injury where one side of the bone bulges or buckles without a complete break.
- Greenstick Fracture: The bone bends and cracks on one side while the other side remains intact.
- Complete Fracture: The bone breaks completely into two or more pieces.
- Physeal (Growth Plate) Fracture: Involves the growth plate near the wrist.
What are the Causes of Pediatric Distal Radius Fractures?
A pediatric distal radius fracture commonly occurs when a child falls onto an outstretched hand, causing force to be transmitted to the distal end of the radius bone near the wrist. Other causes include sports injuries, playground falls, bicycle or scooter accidents, and direct trauma to the forearm or wrist. In some cases, underlying bone conditions such as osteogenesis imperfecta may increase the risk of fractures.
What are the Signs and Symptoms of a Pediatric Distal Radius Fracture?
Common signs and symptoms of a pediatric distal radius fracture include pain and tenderness around the wrist near the distal end of the radius, swelling, bruising, and difficulty moving the wrist or hand. A child may avoid using the affected arm. Visible deformity, reduced grip strength, and pain when touching or moving the wrist area may also occur after injury.
How is a Pediatric Distal Radius Fracture Diagnosed?
Diagnosis of pediatric distal radius fracture begins with a physical examination of the wrist and forearm to check for pain, swelling, tenderness, and deformity around the distal end of the radius. Doctors usually confirm the injury using X-ray imaging. In some cases, additional imaging such as a CT scan or an MRI scan may be used.
How is a Pediatric Distal Radius Fracture Treated?
Treatment of a pediatric distal radius fracture depends on the severity and alignment of the fracture in the distal end of the radius.
Treatment options include the following:
- Immobilization: Most mild or stable fractures are treated with a splint or cast to keep the wrist and forearm still while the bone heals.
- Closed reduction: If the bone is displaced, the doctor gently realigns it without surgery before placing a cast.
- Pain management: Medications such as ibuprofen or acetaminophen may be used to reduce pain and inflammation.
- Surgical treatment: Severe or unstable fractures may require surgery using pins, plates, or screws to hold the bone in the correct position.
- Follow-up care: Regular X-ray checks ensure the bone is healing properly. After cast removal, gentle exercises may help restore wrist strength and movement.
