Distal Tibia & Fibula Fracture (Ankle)

Description

This is a break of both lower-leg bones, the tibia and the fibula, near the ankle, often from a twisting fall or a sports injury. One or both growth plates may be involved.

How it happens (the mechanism)

A twisting force at the ankle breaks both bones together. Getting the joint surface lined up matters for smooth, durable ankle motion, and getting the growth plate lined up matters for even growth, so displaced versions are often stabilized precisely. The great majority of pediatric ankle fractures heal well and grow normally with appropriate care.

Symptoms

Pain, swelling, and often a visible deformity at the ankle, with inability to bear weight.

Doctor examination and imaging

The doctor checks alignment and the foot’s circulation and feeling; X-rays (sometimes with a CT) show both fractures and any joint or growth-plate involvement.

Treatment

A well-aligned fracture is treated in a cast. A displaced fracture is realigned and sometimes held with pins or screws, especially when the joint surface or growth plate is involved. Follow-up X-rays confirm healing and growth.

Recovery and long-term outlook

Most heal well with normal growth; careful alignment of the joint and growth plate is the best protection against later problems.

When to call the doctor

Call the office right away if your child’s toes become numb, pale, blue, or cold; pain keeps worsening even after raising the leg and giving medicine; swelling does not improve with elevation; the cast feels too tight, cracked, or wet, or smells bad; or your child develops a fever.
