Vertebral Fracture Assessment with Densitometry

DESCRIPTION

Vertebral Fracture Assessment (VFA) is a specialized software or additional component to a central dual energy x-ray absorptiometry (DEXA or DXA) scan. VFA with densitometry is a technique to assess vertebral fractures at the same time as bone mineral density (BMD), by use of dual-energy x-ray absorptiometry (DXA). The addition of vertebral fracture assessment to BMD has been proposed as additional information on a subject’s risk of fracture, or as a screening technique for individuals who may be at high risk for vertebral fractures. Several DEXA or DXA scanners with specialized software (e.g., Lunar iDXA™) are able to perform vertebral fractures assessment at the same time as a bone mineral density measurement.

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, radiation exposure, and the fact that a traditional x-ray would require a separate procedure.

IMPORTANT REMINDERS

ADDITIONAL INFORMATION  

The most recent recommendation from the U. S. Preventive Services Task Force on screening for osteoporosis does not address this technology.

The 2014 National Osteoporosis Foundation guidelines recommend this technology for all women and men age 50 and older with certain risk factors. However, there is a lack of direct evidence from screening trials comparing densitometry with and without vertebral fracture assessment (VFA). In addition, clinical input was not uniformly in support of VFA. Therefore, screening for vertebral fractures using VFA with dual-energy x-ray absorptiometry is considered investigational.
