Toddler's Fracture

What is a toddler's fracture?

A toddler's fracture is a particular pattern of fracture, typically a small spiral break of the shin bone (tibia), seen in young children, usually between 1 and 4 years old. It often follows a relatively minor twist or fall, sometimes one parents didn't even notice at the time.

These fractures are stable, generally non-displaced, and heal reliably without surgical intervention. The challenge is more often making the diagnosis than treating the fracture itself.

The classic story is a young child who suddenly starts limping or refusing to weight-bear without a clear injury, leaving parents and clinicians to work out what's going on.

What does it feel like?

The presentation can be subtle:

• Refusal to walk or sudden limping

• Pain on movement of the leg

• Sometimes minimal swelling or bruising

• Tenderness when pressing on the shin

• Often, no clear history of significant injury

A young child unwilling to weight-bear without a clear cause should always be assessed properly, toddler's fractures are one of several diagnoses that need to be considered.

How is it diagnosed?

X-rays are the standard initial investigation. The fracture line is sometimes subtle, a fine spiral crack, and may not be visible on the first set of X-rays. Repeat imaging a week or so later may show the fracture more clearly as healing begins.

Examination establishes the level of pain, the area of tenderness and excludes other causes of refusal to weight-bear. In particular, infection (in the bone or hip) needs to be considered in the differential diagnosis.

Sometimes the diagnosis is essentially one of exclusion early on, with the picture clarifying as time progresses.

What are the treatment options?

Toddler's fractures heal reliably with simple immobilisation: typically a below-knee cast or a walking boot for around three weeks. Surgery is essentially never required.

Children typically resume normal walking once the cast comes off, with a brief period of slight reluctance that quickly resolves. Nev will confirm the right approach for your child at your consultation.

When should you get it checked?

Seek prompt assessment if:

• Your young child refuses to walk or weight-bear

• There's a limp without a clear explanation

• There's tenderness or pain on the shin

• Symptoms haven't settled within a day or two

• You're not sure what's going on and want a proper assessment

A young child not bearing weight is always worth investigating. Most causes are benign and well-managed, but a thorough assessment makes sure nothing important is being missed.
