Greenstick Fracture Explained: A Complete Guide
Broken bones are common injuries. Because children’s bones grow rapidly, they have increased flexibility. When injuries, specifically fractures, occur, they do not always break cleanly across the bone or into pieces. What type of fracture is this, and how are they treated?
Greenstick Fracture
A greenstick fracture is a partial break in a bone that occurs when a bone bends and cracks instead of breaking into separate pieces. (Wolfe J. A. et al., 2019) The term is based on a young green branch that bends and splinters but does not break into pieces when bent. Only one side of the bone is broken, while the other side gets bent. Many children experience at least one fracture during their growing years. This is one of multiple fracture types seen in children. They can happen in adults but are uncommon.
Causes
CausesGreenstick fractures mostly occur in infants or toddlers, sometimes in children during their early adolescent and pre-adolescent years. They are partial-thickness fractures (a break in a bone that doesn’t completely break it) characterized by a break on one side and a bend on the other. Buckle fractures and bow fractures are different types of partial-thickness fractures. Greenstick fractures commonly occur:
- In children under 10 years old
- Occurs when a child reaches out to break a fall
- During motor vehicle collisions
- Sports
- Direct impacts
- Non-accidental trauma
It is more common in long bones, including:
- Radius
- Ulna
- Humerus
- Fibula
- Tibia
- Clavicle
The fracture pattern often indicates a limb’s bending or contortion.
Symptoms
Greenstick fracture symptoms can include:(Atanelov Z, & Bentley T.P. 2025)
- Localized swelling
- Localized bruising
- Pain
- Deformity, such as the affected body part looking crooked or out of alignment.
Treatment
If the bone is not significantly bent out of alignment, a splint or cast may be all that is necessary to treat the break. If the bone is visibly out of alignment, it must be manually straightened before the limb is put into a cast. If the break is severe, surgery may be required. Fortunately, a growing skeleton can remodel bone, so fractured bones can often realign themselves over time with minimal intervention. Healing depends on various factors, including:
- Age of the child
- The severity of the break
- Location of the break
The younger the child is, the faster the recovery will be. (Pountos I., Clegg J., & Siddiqui A. 2010)
Sometimes, the fracture must be bent back and repositioned in a fracture reduction procedure. An anesthetic may be used as the doctor manually realigns the bone into the correct position. After the reduction, a cast or splint will stabilize the bone and maintain proper alignment. Depending on how quickly the bone heals, a cast may be necessary for a few weeks, months, or longer, depending on the patient and/or underlying conditions.
Healing
- Healing involves specialized cells that gradually rebuild and fine-tune the new bone.
- The average time for a greenstick fracture to heal completely may take four weeks.
