Abstract

Isolated periosteal avulsion injuries of the flexor retinaculum on the medial side of the ankle are rare and may mimic osseous injuries or deltoid ligament tears. We describe a case series of 3 individuals with isolated, stripping injuries of the tibial attachment of the flexor retinaculum without underlying fracture or deltoid ligament disruption. A new classification system of flexor retinaculum periosteal stripping injuries of the ankle is proposed with clinico-radiological features.
