What It Is

A greenstick fracture happens when a bone cracks or bends on one side, instead of breaking all the way through into separate pieces. It gets its name because it looks like a young green twig, which only breaks on one side when it is bent (Cambridge University Hospitals NHS Foundation Trust, n.d.). This type of break is common in young children because their bones are softer and more flexible than adult bones. A greenstick fracture of the wrist is one of the most common fractures in young children, usually after falling onto an outstretched hand (Cambridge University Hospitals NHS Foundation Trust, n.d.).

In certain instances, this type of fracture can be difficult to spot because there might not be a lot of pain or swelling, and the child may still be able to use the arm. Mild greenstick fractures can be mistaken for a sprain, and they can be hard to see on an X-ray.

The bone is not completely broken through, as some of the bone remains intact: the break goes through part of the bone and the other side bends (AAOS, n.d.).

Greenstick wrist fractures are usually treated with a splint or a soft cast to support the wrist while it heals (Cambridge University Hospitals NHS Foundation Trust, n.d.; University Hospitals Sussex NHS Foundation Trust, 2025). They normally take about 4 to 6 weeks to heal, and it is normal for the wrist to ache for a few weeks after this (University Hospitals Sussex NHS Foundation Trust, 2025).

Greenstick Fracture of Distal Radius Anatomy

The forearm is made up of two bones, the radius and the ulna. The radius is on the thumb side of the forearm, and the ulna is on the little-finger side (AAOS, n.d.).

Fractures of the forearm can happen near the wrist, at the far (distal) end of the bone; in the middle of the forearm; or near the elbow, at the top (proximal) end of the bone (AAOS, n.d.). A greenstick fracture of the distal radius is a break near the wrist end of the radius.

Children love to run, hop, skip, jump and tumble around. If a child falls onto an outstretched arm, they might break one or both of the forearm bones (AAOS, n.d.).

Looking After Your Child at Home

  • Encourage your child to keep their fingers, thumb, elbow and shoulder moving to prevent stiffness (University Hospitals Sussex NHS Foundation Trust, 2025).
  • Swelling and pain in the wrist and hand are common for a few weeks and are often worse at the end of the day; raising (elevating) the wrist helps (University Hospitals Sussex NHS Foundation Trust, 2025).
  • If the cast feels too tight, make sure the arm is raised enough, and check that your child can wriggle their fingers and that the fingers are a good colour. Contact the fracture clinic if you are worried (University Hospitals Sussex NHS Foundation Trust, 2025).
  • Your child should avoid sport and high-impact activities, such as trampolines, scooters and football, for 4 to 6 weeks. Non-contact sports such as swimming can usually be started as soon as your child is comfortable (University Hospitals Sussex NHS Foundation Trust, 2025).
  • When the cast comes off, the wrist may be stiff for 2 to 3 weeks, and the bone is weaker for a short time; avoid climbing frames such as monkey bars for 3 to 4 weeks afterwards (AAOS, n.d.).
  • If your child still has significant pain or swelling after 6 weeks, contact the fracture clinic (University Hospitals Sussex NHS Foundation Trust, 2025).
