Tillaux Fracture
- Lateral margin avulsion of the distal tibia.
- Results from injury involving a combination of abduction and external rotation.
- Look for a vertical fracture line extending from the distal articular surface upward
to the lateral cortex of the tibia.
- Careful radiologic exam is critical for determining the neccesity of surgery. If there
is greater than 2 mm lateral displacement of the fracture fragment or step-off of the distal
articular surface, surgery is often required. Otherwise, conservative treatment is indicated.
CT is most commonly the method of choice for this evaluation.
