Diagnosis is made clinically with pain over the 5th metartarsal base with radiographs showing an enlarged apophysis with disordered. There are five metatarsal bones each of which is located in the forefoot (figure 1). Iselins Disease is a common acquired condition cause by traction apophysitis of the the peroneus brevis tendon at the tuberosity of the fifth metatarsal in children and presents with lateral foot pain. A vascular watershed area exists in zone 2, contributing to the high nonunion rates seen with these fractures.Ĭopyright © 2023, StatPearls Publishing LLC. A metatarsal stress fracture is a condition characterized by an incomplete crack in one of the metatarsal bones. These bones help with arch support and balance. The fifth metatarsal connects your smallest toe to your hindfoot. They are the middle bones in your feet, between your toes and your ankle bones (tarsals).

Nevertheless, it is critical that the clinician recognizes all injury patterns of the fifth metatarsal and initiate the appropriate treatment plan or referral process to avoid potential complications.Ĭlassified by Lawrence and Bottle, the base, or proximal aspect, of the fifth metatarsal is broken up into three anatomical zones: zone 1, the tuberosity zone 2, the metaphyseal-diaphyseal junction and zone 3, the diaphyseal area within 1.5 cm of the tuberosity. The 5th metatarsal is the smallest of these and sits on the outer side of the forefoot. Cleveland Clinic is a non-profit academic medical center. Your fifth metatarsal is the long bone on the outside of your foot that connects to your little toe. Located along the forefoot, there are 5 metatarsals in a foot.
