Classification of proximal fifth metatarsal fractures

Tuberosity avulsion (styloid) fracture - Medial end of fracture line lies proximal to intermetatarsal joint of the fourth and fifth metatarsals.

Acute proximal diaphyseal fracture ("Jones fracture") - Medial end of fracture line extends into or toward intermetatarsal joint.

Stress fracture of the diaphysis - Medial end of fracture line typically exits bone distal to intermetatarsal joint, but some fracture lines lie more proximal and extend into the distal portion of the joint.

Torg type I (early)

Torg type II (delayed union)

Torg type III (nonunion)
