Transverse linear fracture at the base of the 5th metatarsal approximately 1.2 cm distal to the styloid process
Case Discussion
A number of fractures and fracture mimics occur at the base of the 5th metatarsal. Therefore, it is essential to understand the zonal division of fractures of the proximal fifth metatarsal.
- Jones fracture: occurs at the metaphysis-diaphysis junction, at the level of the fourth-fifth intermetatarsal articulation
- stress fracture of the 5th metatarsal: occurs at the proximal diaphysis, distal to the level of the fourth-fifth intermetatarsal articulation
- pseudo-Jones fracture: usually of the tuberosity of the proximal 5th metatarsal, oriented mostly transversely (cf. apophysis which parallels the shaft).
- os peroneum
- os vesalianum pedis
- normal apophysis of the proximal 5th metatarsal
