Vertebral Fracture Assessment with Densitometry
Vertebral Fracture Assessment (VFA) with densitometry is a technique to assess vertebral fractures at the same time as bone mineral density, using additional software with dual-energy x-ray absorptiometry. The addition of vertebral fracture assessment to BMD has been proposed as a technique to diagnose whether an individual has a vertebral fracture. Additional software is necessary to perform VFA with a densitometer and several products have received FDA clearance (e.g., Lunar Dual Energy Vertebral Assessment [DVA™] and Instant Vertebral Assessment [IVA™].
Only 20–30% of vertebral fractures are recognized clinically, and they are highly prevalent in the elderly population. The standard technology for diagnosing vertebral fractures is lateral spine x-rays. Lateral spine x-rays have not been recommended as a component of risk assessment for osteoporosis because of the cost and radiation exposure.
Vertebral Fracture Assessment using dual x-ray absorptiometry (DEXA or DXA) is considered investigational.
