Are children more prone to certain fractures or sprains?
Children are indeed more susceptible to specific types of bone injuries that are rarely seen in adults. This is because their skeletal system is still developing, which means their bones are more flexible and contain specialised areas called growth plates. In the UK, clinicians categorise paediatric injuries differently because a child’s bone will often bend or fail partially rather than snap completely. Furthermore, because a child’s ligaments are frequently stronger than their developing bone, what looks like a severe ankle sprain in an adult is often a growth plate fracture in a child.

The Biology of Growing Bones
A child’s bone has a much higher ratio of collagen to mineral compared to an adult’s. This makes the bone more “elastic” and allows it to absorb more energy before breaking. While this flexibility can prevent some injuries, it leads to unique types of fractures:
- Buckle (Torus) Fractures: These occur when the bone is compressed and the outer layer “bunches up” or buckles. They are extremely common in the wrist after a fall.
- Greenstick Fractures: Similar to a young, green branch on a tree, the bone breaks on one side but only bends on the other.
According to the NHS guide on common childhood injuries, these injuries often require a simple splint rather than a heavy plaster cast, as they are very stable.
The Growth Plate: The Vulnerable Link
The most critical difference in pediatric orthopaedics is the presence of the growth plate (physis). This is a layer of developing cartilage near the ends of the long bones.
- The Weakest Point: In a growing child, the growth plate is the weakest part of the skeletal system.
- Sprains vs. Fractures: Because the ligaments surrounding a joint are tougher than the growth plate, a twisting force will often cause the growth plate to fracture before the ligament tears.
- Long-term Impact: Injuries to this area require careful monitoring in the UK to ensure the bone continues to grow straight and at the correct speed.
Why True Sprains are Rare in Young Children
While teenagers can suffer ligament sprains similar to adults, true sprains are quite rare in children under the age of twelve. If a young child has a very swollen ankle or wrist after an injury, UK clinicians will almost always treat it as a suspected fracture until proven otherwise. The philosophy used in pediatric emergency departments is that a child’s ligament will not tear, but the bone will fail.
Common Pediatric Bone Injuries
| Injury Type | Primary Cause | Typical Treatment |
| Buckle Fracture | Fall onto an outstretched hand | Removable splint for 3 weeks |
| Greenstick Fracture | Significant fall or impact | Plaster cast for 4 to 6 weeks |
| Growth Plate Fracture | Twisting injury to ankle or wrist | Specialist monitoring and cast |
| Toddler’s Fracture | Minor trip or twist (tibia) | Often a walking boot or cast |
Conclusion
Children are not simply small adults; their bones have unique physical properties that dictate how they break and heal. By recognising that a child’s “sprain” is often a growth plate fracture and understanding the stability of buckle and greenstick breaks, parents and coaches can ensure the correct clinical path is followed. In the UK, the focus is on protecting the growth plates to ensure the child reaches their full adult height and joint alignment without complication. If your child experiences severe, sudden, or worsening symptoms, call 999 immediately.
Why is it called a “Torus” fracture?
The word comes from the Latin “tori,” which refers to a rounded swelling or architectural bulge, describing the way the bone layer bunches up.
Will my child’s bone be weaker after it heals?
Actually, during the healing process, the body often creates a “fracture callus” that is temporarily stronger than the original bone. In the long term, the bone will return to its normal strength.
Do children heal faster than adults?
Yes. Because children have a very active blood supply and a thick “periosteum,” which is the skin of the bone, they can often heal a fracture in half the time it takes an adult.
What if the growth plate is permanently damaged?
While rare, this can lead to the bone growing slightly crooked or stopping growth early. This is why UK fracture clinics insist on follow-up appointments for these specific injuries.
Can my child go back to PE with a buckle fracture?
Usually, children are advised to avoid high-impact sports for about six weeks to ensure the bone has fully solidified, even if they are in a splint.
Is a “Greenstick” fracture serious?
It requires a cast because the bone has a tendency to “bow” as it heals. A specialist may sometimes need to gently straighten the bone before casting.
Why did the hospital only give my child a bandage for a wrist break?
For very stable buckle fractures, a “backslab” or a removable Velcro splint is now the preferred UK treatment as it allows for better hygiene and comfort.
