Adult-type bimalleolar ankle fracture in children: report of two cases.

UNLABELLED: Ankle fractures patterns in children may vary depending on the maturity of the distal tibial and fibular physis. Bimalleolar ankle fracture is an exceedingly rare fracture pattern in children and has been reported once in the current English literature. Two further adolescents with bimalleolar ankle fracture are reported. Although these fractures are rare, surgeons should be aware of these atypical fracture patterns. Herein, the underlying physiology and the mechanism of injury of ankle fractures in children are discussed. LEVEL OF EVIDENCE: Therapeutic, Level IV, Case study.
