Distinguishing the difference between Jones and Proximal Diaphyseal Fractures of the Fifth Metatarsal can be complicated, here are some examples from PubMed; 

A Jones fracture currently is defined as an acute fracture of the fifth metatarsal at the junction between the proximal diaphysis and metaphysis of the fifth metatarsal without distal extension beyond the fourth to fifth intermetatarsal articulation.

Tuberosity avulsion fracture (also known as pseudo-Jones fracture or dancer's fracture)

A proximal diaphyseal fifth metatarsal stress fracture is defined as a stress fracture in the zone of the proximal fifth metatarsal immediately distal to the Jones fracture’s anatomic area.
