| 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) |
