A New Radiographic Classification for Distal Shaft Fifth Metatarsal Fractures.

In the present report, a new radiographic classification for distal shaft fractures of the fifth metatarsal is presented. The classification system is based on a review of 79 spiral oblique fractures of the distal shaft of the fifth metatarsal. The sample was grouped into "grades" of deformity according to the configuration of the fracture and the amount of displacement observed for each injury.
