Fracture non-union
Updates to Article Attributes
Fracture non-union describes the failure of the normal biologicfracture healing processes cease to the extent that solid. Solid healing will not occur without further treatment intervention.
There is no consensus in the radiology or orthopedic literature, however, FDA defines it as a fracture with a minimum of at least nine months since the initial injury with no signs of healing for the final three months.
There are differenttypes of fracture non union-union with various imaging characteristics:
HypertrophicAbundantabundant callus formation; radiolucent line (unmineralized fibrocartilage) at the nonunion site.Oligotrophicoligotrophic:Littlelittle or no callus formation; diastasis at the fracture site.Atrophicatrophic:Bonybony surfaces partially resorbed; no callus formation; osteopenia; sclerotic avascular bone segments; segmental bone loss.Infectedinfected:Osteolysisssteolysis; osteopenia; sclerotic avascular bone segments; segmental bone loss.Synovialsynovial pseudarthrosis:Variable Variablevariable appearance (hypertrophic, oligotrophic, or atrophic).
