Atypical Femur Fracture (AFF)

Quantify, Visualize, and Trend Incipient Atypical Femoral Fractures using DXA Technology from GE Healthcare

The Atypical Femur Fracture application in enCORE version 17 for Lunar iDXA™ DXA system and Prodigy™ with Pro and Advance software packages provides clinicians with the ability to identify and assess early evidence of atypical femur fractures without exposing patients to additional radiation through a CT scan or to the cost and inconvenience of an MRI.1

Atypical femur fracture measurement and analysis provides a dual-energy X-ray image of the entire femur for both qualitative visual assessment and quantitative measure to identify areas of focal thickening along the lateral cortex of the femoral shaft. The AFF measurement also provides bone mineral density (BMD) values.

The software provides a “Beaking Index” value, which is a measure of the magnitude of the increase in the cortical width (mm) at the location of the localized periosteal reaction along the femoral shaft.

Our iAFF application provides various benefits to the Physicians:

 

  • Quantitative measurement of early “beaks” along the femoral shaft
  • Qualitative visual assessment
  • Graphically trend incipient AFFs over time
  • Proximal and Distal femur acquisition in a single scan - calculate both BMD and AFF, if present
  • Ability to run retrospective scans to uncover early signs of atypical femur fractures among patient population
