Operates by applying World Health Organization (WHO) diagnostic criteria to classify bone density status: T-scores +1 to -1 (normal), -1 to -2.5 (low bone mass/increased fracture risk), below -2.5 (osteoporotic/high fracture risk). Output presented as graphical and textual information on device screens and reports. Used by clinicians in clinical settings to assist in fracture risk assessment and treatment monitoring. Does not alter scanning hardware, patient dose, or radiation exposure. ## Clinical Evidence No clinical data provided. The device relies on established World Health Organization (WHO) criteria for interpreting bone density values (BMD and T-scores) to assess fracture risk. ## Technological Characteristics Software-based assessment module for existing Norland X-Ray Bone Densitometers. Utilizes rule-based logic to map BMD/T-score values and patient demographics to WHO fracture risk categories. No hardware changes, no impact on radiation dose or scan time. Integrated into existing densitometer reporting software. ## Regulatory 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. ## Predicate Devices - Fracture Risk Assessment for pDEXATM Bone Densitometer ([K973104](/device/K973104.md)) - Fracture Risk Assessment for the Norland-Cameron Model 178 Bone Mineral Analyzer ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Submitted by: W6340 Hackbarth Road Fort Atkinson, WI 53538 Reg. # 2124648 Contact Person: Mr. Terry Schwalenberg Director Regulatory Affairs 920-563-8456 x229 Fracture Risk Assessment Capability for Norland X-Ray Bone Device Trade Name: Densitometers Common Name: Fracture risk assessment for bone densitometers Classification: Bone densitometer. (21 CFR 892.1170), product code 90KGI: Class II Fracture Risk Assessment for pDEXATM Bone Densitometer (K973104) Predicate Devices: Norland Medical Systems, Inc., Fort Atkinson, WI Fracture Risk Assessment for the Norland-Cameron Model 178 Bone Mineral Analyzer, which is a pre-amendment device. Description of This fracture risk assessment capability provides information that aids the Device: physician in determining risk of fracture, risk of bone disease, or treatment effectiveness. This fracture risk assessment capability interprets the results of the bone density tests performed by Norland bone densitometers in accordance with methods in general use in the medical community. In general they use the bone densitometer values (usually BMD and T-Score) and patient information (usually gender, age, and ethnic background). The interpretation is based on the World Health Organization's (WHO) criteria relating bone density to risk of fracture and diagnosis of osteoporosis. In general, the WHO criteria means that patients with T-Scores from +1 to -1 are considered to be normal; with T-Scores from -1 to -2.5 are considered to have low bone mass and have an increased risk of fracture; and with T-Scores below -2.5 are considered to be osteoporotic {1}------------------------------------------------ and have a high risk of fracture. This information is presented graphically and as verbiage on the screens and reports. This fracture risk capability does not require any modifications to the Norland bone densitometers besides adding the fracture risk information to the screens and printouts. In particular, it does not increase the scanning time, patient dose, or scatter radiation. This Norland Fracture Risk Assessment Capability is comparable to Safety and Effectiveness: fracture risk assessment capabilities in use with other bone densitometers in the industry. No new safety or effectiveness issues are raised. {2}------------------------------------------------ ## DEPARTMENT OF HEALTH & HUMAN SERVICES Public Health Service Food and Drug Administration 9200 Corporate Boulevard Rockville MD 20850 Image /page/2/Picture/2 description: The image shows the logo for the U.S. Department of Health & Human Services.
