Fractures of the 5th Metatarsal Bone
Fractures of the 5th Metatarsal Base
Fractures of the base are sometimes called dancer's or pseudo-Jones fractures. The mechanism is usually a crush injury or an inversion force that causes avulsion by the peroneus brevis tendon. These fractures are more common than acute diaphyseal fractures (Jones fractures). Because the base, unlike the diaphysis, has abundant collateral circulation, delayed union and nonunion are rare. Symptomatic Treatment of 5th metatarsal base fractures is symptomatic and may include a hard-soled shoe or walking boot and weight bearing as tolerated.
