Intended Use

The Fracture Risk option is used with the LUNAR EXPERT-XL bone densitometer system. 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 EXPERT-XL is restricted to prescription use only. The operator's manual for the EXPERT-XL 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."

Device Story

Software accessory for LUNAR EXPERT-XL bone densitometer; utilizes existing bone mineral density T-score data from patient examinations; applies World Health Organization (WHO) fracture risk categories to classify patient risk; provides output to physicians to aid in osteoporosis diagnosis and fracture risk assessment; does not alter scan parameters or primary densitometry results; used in clinical settings by trained operators; assists physician clinical decision-making by contextualizing bone density results; benefits patients through standardized risk stratification.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Software accessory for existing bone densitometer; utilizes T-score data; implements WHO-defined fracture risk classification logic; no changes to hardware or scan parameters.

Indications for Use

Indicated for patients undergoing bone mineral density assessment via the LUNAR EXPERT-XL system to provide an assessment of relative fracture risk based on WHO-defined T-score categories. Restricted to prescription use.

Regulatory Classification

Identification

A bone densitometer is a device intended for medical purposes to measure bone density and mineral content by x-ray or gamma ray transmission measurements through the bone and adjacent tissues. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.

### DESCRIPTION OF THE DEVICE: 9.1

The Fracture Risk option for EXPERT-XL is a new software feature, providing fracture risk assessment based on the patient's bone mineral density T-score.

## SUMMARY OF TECHNICAL CHARACTERISTICS 9.2

The Fracture Risk option for EXPERT-XL is a software accessory to aid the physician in assessing fracture risk from the results of an EXPERT-XL bone density examination. The Fracture Risk Assessment Feature does not cause any changes to the scan parameters used in the examination, and it does not affect the results produced.

{1}------------------------------------------------

#### 9.3 CONCLUSION

The Fracture Risk option for EXPERT-XL is substantially equivalent to the Norland-Cameron Model 178 Bone Mineral Analyzer, a pre-amendment device that was used to aid the physician in determining fracture risk. No new safety and effectiveness questions are raised with the Fracture Risk option for the EXPERT-XL bone densitometer.

Dear Mr. Buroker:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Feceral Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will vecify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.

This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
