Triplane ankle fracture

Abstract

Triplane ankle fractures, accounting for 5 to 7% of paediatric ankle fractures, are intra-articular with potentially significant functional sequelae if the diagnosis is missed. We present a case of a previously well adolescent boy who sustained this injury during sports through a benign mechanism. This case report discusses key considerations in clinching the diagnosis in an ambulatory care setting and highlights essential factors that inform subsequent definitive management.
