From: Can body mass index influence the fracture zone in the fifth metatarsal base? A retrospective review
Radiographic classification of the fractures according to Lawrence and Botte7. The three different zones are based on anatomic landmarks (far left): proximal to the meta-diaphyseal junction involving the tuberosity (zone 1, centre left), between the lines of the intermetatarsal joint between fourth and fifth metatarsal bones involving the meta-diaphyseal junction and the intermetatarsal articular facet (zone 2, centre right), distal to the meta-diaphyseal junction involving the proximal diaphysis (zone 3, far right)
