Jones fracture occurs at which location?

Explanation:
Jones fracture is a fracture at the metaphyseal-diaphyseal junction of the fifth metatarsal, about 1.5 to 3 cm distal to the base. This location sits in the proximal shaft where blood supply is relatively limited, which helps explain the higher risk of delayed healing or nonunion compared with fractures closer to the base. It’s distinct from an avulsion fracture at the base of the fifth metatarsal, which involves the tuberosity where the peroneus brevis attaches. So, the correct location is the metaphyseal-diaphyseal junction of the fifth metatarsal.
