Jones fracture

  • Fracture of proximal metaphyseal 5th metatarsal
    • located w/in 1.5 cm distal to tuberosity of 5th metatarsal
  • Prone to malunion
    • Watershed area (poor blood supply)
    • Under tension from multiple tendons
  • Treatment
    • Immobilize with posterior-mold splint
    • Non-weight bearing - crutches
    • Prompt orthopedic evaluation
      • Some cases are managed with non-weight bearing casts
      • Others are repaired operatively.
      • Delayed jones fractures with malunion will require operative repair.
  • Distinguish from pseudo-jones fracture (dancers fracture)
    • metatarsal styloid avulsion fracture, generally does not require operative repair
    • much more common than true Jones fracture.
