Nonunion of fifth metatarsal fractures.

Metatarsal fractures are those most frequently encountered in the foot. More than half of these are of the 5th metatarsal. The incidence is increasing, along with the activity levels of the general population. Fractures of the 5th metatarsal require careful evaluation and classification to ensure selection of the optimum treatment plan. Distal fractures rarely require fixation, even when displacement is wide. Cases of established nonunion or refracture require fixation.
