Five patients sustained fractures of the os peroneum after supination and plantarflexion injuries. Two of the injuries involved the knee in hyperflexion and the foot under the buttock. Four of the five were treated with immobilization for 6 weeks. All five required operative excision of the fractured sesamoid 8 months to 8 years after the initial injury. Three fractures were bipartite and there were two multipartite fractures. At 12- to 28-month follow-up, all patients were pain-free over the lateral midfoot and four patients returned to preinjury activity levels.
