Anterolateral avulsion fracture of the distal tibial physis is known as -: (A) Potts fracture, (B) Tillaux frascture, (C) Choparacture, (D) Jones fractture
Answer is B. Two unusual injuries of the growing ankle are the Tillaux fracture and the notorious triplane fracture. The TILLAUX fracture is an avulsion of a fragment of tibia by the anterior tibiofibular ligament; in the child or adolescent this fragment is the lateral pa of the epiphysis and the injury is therefore a Salter-Harris type 3 fracture.
