Children’s Ankle Injuries Are Different from Adults

When a child sprains an ankle during youth sports, gymnastics, or play, the temptation is to manage it the way you would treat an adult ankle sprain — rest, ice, compression, and elevation (RICE). For many pediatric ankle injuries, this approach is appropriate. But there is an important physiological difference between a child’s ankle and an adult’s: the presence of open growth plates (physes) at the ends of growing bones makes certain injuries look clinically similar to ligament sprains but are actually fractures through the vulnerable growth plate cartilage, with potentially different management requirements.

At Balance Foot & Ankle in Howell and Bloomfield Township, Michigan, Dr. Tom Biernacki DPM and Dr. Daria Gutkin DPM evaluate pediatric ankle injuries with this distinction in mind, ensuring that growth plate fractures — which require specific treatment to protect normal bone growth — are not missed. Understanding when your child’s ankle injury needs professional evaluation helps parents make informed decisions about when home management is appropriate and when imaging is needed.

Why Growth Plates Matter

Open growth plates are regions of cartilage at the ends of long bones where new bone is produced and bone elongation occurs. They remain open (unfused) until skeletal maturity — in most children, the ankle growth plates close between ages 14–16 in girls and 16–18 in boys. Before closure, the growth plate cartilage is weaker than the adjacent bone and ligaments, meaning that the forces that would stretch and tear ligaments in an adult can instead fracture through the growth plate in a child.

The most important growth plate fracture around the ankle in children is the Salter-Harris fracture of the distal fibula — the outer ankle bone’s growth plate is at the very tip of the fibula, precisely at the location of maximal tenderness in a typical lateral ankle sprain. Clinical findings of a distal fibula growth plate fracture and a lateral ankle ligament sprain overlap significantly: both produce pain and tenderness at the outer ankle, swelling, and difficulty bearing weight. Growth plate fracture requires immobilization and follow-up imaging to confirm healing; a pure ligament sprain may not.

Salter-Harris Classification: What Your Radiologist Means

Growth plate fractures are classified using the Salter-Harris system. Type I fractures involve only the growth plate (no bony fracture visible on X-ray); Type II fractures extend through the growth plate into the metaphysis (common and low-risk); Types III and IV fractures extend into the joint surface and are more serious because they disrupt the articular cartilage; Type V fractures involve crush injury to the growth plate (rare but most concerning for growth disturbance).

Type I Salter-Harris fractures of the distal fibula may appear normal on standard X-rays and are diagnosed clinically — tenderness directly over the fibular growth plate in a child with an inversion injury should be treated as a probable growth plate fracture even with normal imaging. A brief period of immobilization (typically 2–3 weeks in a boot or cast) allows safe healing and prevents complications from undetected growth plate injury.

Treatment of Pediatric Ankle Sprains and Growth Plate Fractures

For confirmed or suspected distal fibula growth plate fractures, immobilization in a short-leg cast or walking boot for 2–4 weeks is standard, depending on the fracture type and displacement. Most pediatric ankle growth plate fractures heal completely with conservative management; surgery is rarely needed unless significant displacement is present. Follow-up X-ray at 3–4 weeks confirms healing before return to full activity.

True ankle ligament sprains in children (without growth plate involvement) are managed identically to adult sprains — RICE in the acute phase, protected weight-bearing as tolerated, and progressive rehabilitation including proprioceptive training. Children actually tend to recover from ankle sprains faster than adults due to their superior tissue healing capacity and adaptation. However, the same principles of adequate rehabilitation before return to sport apply — returning too quickly before neuromuscular function is restored increases re-sprain risk in young athletes just as much as in adults.

When to See a Podiatrist After a Pediatric Ankle Injury

Parents should seek evaluation when: the child cannot bear weight immediately or within 1 hour of injury; there is point tenderness directly over the bony prominences (fibula or tibia); significant swelling or bruising develops rapidly; or the child is not walking normally after 3–5 days of home management. The Ottawa Ankle Rules — clinical guidelines widely used to decide whether X-rays are needed — have been validated in children over age 5 and can guide this decision, though they are best applied in the context of an in-person clinical evaluation. When in doubt, having a child’s ankle injury evaluated professionally is always appropriate.

When to See a Podiatrist for Pediatric Ankle Injuries

Ankle sprains in children can mask growth plate injuries that require different treatment than adult sprains. A podiatrist can distinguish between a simple sprain and a growth plate fracture to ensure proper healing. Balance Foot & Ankle provides expert pediatric ankle care.
