Daily Bolus of LR: 5th metatarsal fractures

June 7, 2011 by dailybolusoflr

The base of the 5th metatarsal has two main fractures that you will see.

 

Avulsion fractures or “pseudo-Jones” fractures

  • The most common
  • Is a fracture at the base or tuberosity
  • Typically is sudden onset of pain with inversion of the foot with the ankle plantar flexed (this flexed position also leads to the name “dancer’s fracture”)
  • Most are nondisplaced and can be treated with a walking case with weight bearing as tolerated

 

Jones fractures

  • Less common
  • Is a fracture within 1.5 cm of the tuberosity
  • Often described as  lateral force on the forefoot while the ankle is in plantar flexion (often a sports injury or stepping off a curb)
  • High rates of nonunion and ALL fractures should be treated as NON WEIGHT bearing and referred for follow up
