Proximal fractures of 5th metatarsal.jpg

In radiology, proximal fractures of the fifth toe are most appropriately classified by their location:

  • A proximal diaphysis fracture is typically a stress fracture, commonly among athletes.[1][2]
  • A metaphysis fracture or "Jones fracture"; Due to poor blood supply in this area, such a fracture sometimes does not heal and surgery is required.[3]
  • A tuberosity fracture or "pseudo-Jones fracture"/"dancer's fracture".[4] It is typically an avulsion fracture.[5]

Normal anatomy that may simulate a fracture include mainly:

  • The "apophysis", which is the secondary ossification center of the bone, and is normal at 10 - 16 years of age.[6]
  • Os vesalianum, an accessory bone which is present in between 0.1 - 1% of the population.[7]
