Metatarsal shaft fractures and fractures of the proximal fifth metatarsal

The forefoot has been described to serve two primary functions: (1) provide a broad rigid platform for weight bearing and (2) provide a mobile platform to accommodate uneven ground while ambulating [1]. The metatarsal bones, phalanges, and surrounding structures provide this platform. Fractures of the metatarsals are common injuries and can alter the functional characteristics of this platform. Although metatarsal fractures can occur from any traumatic event, high-performance and recreational athletes are at increased risk. The pertinent anatomy, evaluation, diagnosis, classification, and treatment of acute and chronic (stress) metatarsal shaft fractures are discussed in this article. Fractures of the proximal fifth metatarsal, which are unique and important injuries, are discussed and emphasized separately.
