title: Fractures of the base of the fifth metatarsal.
abstract: In 1902 Sir Robert Jones described a fracture of the fifth metatarsal which he incurred while dancing. Since that time, fractures of the base of the fifth metatarsal have been called "Jones fractures". Fractures of the tuberosity at the base of the fifth metatarsal are common and usually respond readily to conservative treatment. Less frequently the fracture occurs more distally through the proximal metaphysis. Eleven patients with fractures of the proximal metaphysis were reviewed to determine if they represented a clinically distinct subgroup. Seven of the patients were men between 19 and 25 years of age who fractured the fifth metatarsal playing sports. The fractures were slow to heal and one required internal fixation with bone grafting. Fractures of the proximal metaphysis of the fifth metatarsal have a different mechanism of injury and a less favourable prognosis than do tuberosity fractures. When they occur in young athletes, more aggressive treatment is required.
