## Indications for use
The Fracture Risk option is used with the LUNAR DPX Series of bone densitometer systems. This option provides an assessment of relative fracture risk based on the patient’s T-score value using the categories of fracture risk defined by the World Health Organization (WHO). Physician and patient information is provided to indicate that although bone density is the single most important factor in the assessment of fracture risk and the diagnosis of osteoporosis, the physician should also consider other factors. The use of the Fracture Risk option for DPX Series is restricted to prescription use only. The operator’s manual for the DPX system contains the following statement: “United States Federal Law restricts this device to the sale, distribution, and use by or on the order of a physician.” The Fracture Risk option for DPX Series poses no new safety or efficacy concerns.
