Non-union Tibial Fracture

General Considerations

  • Delayed union is the term applied when a fracture has not healed within the period of time that would be considered adequate for bone healing for that particular sites
    • Holds out the promise that union will eventually occur without further intervention
    • For tibial fractures, healing should occur in 16 weeks
  • Non-union is the term applied to a fracture that will not unite without additional intervention
    • Usually by 6-9 months for tibial fractures
  • Non-union of tibia is fairly common
  • Estimated to range from 2-10% of all tibial fractures
