This type of fracture is common in children under 10 years of age.
A greenstick fracture occurs when a bone bends and cracks, instead of breaking completely into separate pieces. The fracture looks similar to what happens when you try to break a small; branch on a tree.
Most greenstick fractures occur in children younger than 10 years of age. This type of broken bone most commonly occurs in children because their bones are softer and more flexible than are the bones of adults.
Even mild greenstick fractures are usually immobilized in a cast.
Signs and symptoms will vary, depending on the severity of the greenstick fracture. Mild fractures might be mistaken for sprains or bruises. More-severe greenstick fractures may cause an obvious deformity, accompanied by significant pain and swelling.
Contact your doctor if your child has persistent pain in an injured limb.
Seek immediate medical attention if a child:
- Is unable to bear weight
- Has obvious pain
- Has deformity
- Has swelling.
Childhood fractures most commonly occur with a fall. Arm fractures are more common than leg fractures, since the common reaction is to throw out your arms to catch yourself when you fall.
