tillaux fracture
Adolescent ankle fracture involving the anterolateral aspect of the distal tibial epiphysis during growth plate closure.
Full Definition
A Salter-Harris III fracture specific to adolescents that occurs through the anterolateral portion of the distal tibial epiphysis and extends into the ankle joint. This injury pattern develops during the asymmetric closure of the distal tibial growth plate, where the anteromedial aspect closes before the anterolateral region. The fracture typically results from external rotation forces and may be associated with fibular fractures. Accurate reduction is essential to prevent post-traumatic arthritis, and the injury often requires operative fixation if displaced.
Usage
Usage note: Capitalize 'Tillaux' as it derives from the anatomist's name. Often preceded by 'juvenile' in pediatric contexts.
