Stewart classification for proximal 5th metatarsal fractures

The Stewart classification for proximal fifth metatarsal fractures is based upon fracture location and morphology. It is divided into five types.


Type I
  • extra-articular transverse or oblique fracture between base of 5th metatarsal and diaphysis (Jones fracture)
Type II
  • avulsion fracture of base of 5th metatarsal with intra-articular extension
  • may have one or two fracture lines
Type III
  • avulsion fracture of styloid process of 5th metatarsal
  • fracture line usually makes a right angle to the long axis of the metatarsal base
Type IV
  • intra-articular comminuted fracture 
Type V
  • usually occurs in children
  • partial epiphyseal avulsion with or without fracture line
  • can be classified as Salter-Harris I type fracture
