Indications for Use
TBS iNsight is a software provided for use as a complement to both DXA analysis and clinical examination. It computes the antero-posterior spine DXA examination file and calculates a score (Trabecular Bone Score - TBS) that is compared to those of the age-matched controls. The TBS is derived from the texture of the DXA image and has been shown to be related to bone microarchitecture. TBS iNsight provides as an option an assessment of 10-year fracture risk. It provides an estimate of 10-year probability of hip fracture and 10-year probability of a major osteoporotic fracture (clinical spine, forearm, hip or shoulder fracture). This estimate is based on the WHO's FRAX® Fracture Risk Assessment Tool, after adjustment for the TBS. The tool has been validated for Caucasian and Asian men and post-menopausal women between 40 and 90 years old. TBS provides information independent of BMD value; it is used as a complement to the data obtained from the DXA analysis and the clinical examination (questioning by the clinician about patient history, bioassay of bone resorption markers...). The results can be used by a physician in conjunction with other clinical risk factors as an aid in the diagnosis of osteoporosis and other medical conditions leading to altered trabecular bone microarchitecture, and ultimately in the assessment of fracture risk. The TBS score can assist the health care professional in monitoring the effect of treatments on patients across time. Overall fracture risk will depend on many additional factors that should be considered before making diagnostic or therapeutic recommendations. The software does not diagnose disease, or recommend treatment regimens. Only the health care professional can make these judgments.
Device Story
TBS iNsight is software used by clinicians to analyze raw DXA images of the lumbar spine. It calculates a Trabecular Bone Score (TBS) based on image texture, which serves as a proxy for bone microarchitecture. The software integrates this TBS with the WHO FRAX tool to provide an adjusted 10-year fracture risk probability. It operates as a complement to standard DXA analysis and clinical history. Physicians use the output—TBS scores, T-scores, Z-scores, and fracture risk percentages—alongside other clinical risk factors to aid in diagnosing osteoporosis and monitoring treatment efficacy. The device does not diagnose disease or recommend specific treatments; it provides data to support clinical decision-making.
Clinical Evidence
Clinical evidence includes three published studies and a report from the Frax group validating the use of TBS as an independent clinical risk factor to adjust WHO FRAX probabilities. Additional evidence includes a cohort study of 29,000 Canadian women to establish fracture risk categories, with subsequent studies confirming applicability to the US population. Normative data was derived from the NHANES IV database, covering a diverse US population (Non-Hispanic white, Non-Hispanic black, and Mexican men and women, aged 20-85) to establish age-related TBS trends.
Technological Characteristics
Software-based analysis of DXA images. Utilizes Dual Energy X-ray Absorptiometry (DXA) input. Provides Lumbar Spine TBS, TBS T-scores/Z-scores, and FRAX-adjusted fracture risk. Developed in accordance with IEC 62304 (software life cycle), ISO 14971 (risk management), and FDA guidance for off-the-shelf software and cybersecurity.
Indications for Use
Indicated for Caucasian and Asian men and post-menopausal women aged 40-90 years as a complement to DXA analysis and clinical examination to assess bone microarchitecture and 10-year fracture risk (hip and major osteoporotic).

## CONFORMITY TO RECOGNISED STANDARDS
TBS iNsight has been developed in accordance with the following product standards & FDA Guidance :
- 1. IEC 62304:2006, Medical Device Software: Software Life Cycle Processes
- II. ISO 14971:2007, Medical Devices: Application of Risk Management to Medical Devices
- III. General Principles of Software Validation: Final Guidance for Industry and FDA Staff (2002)
- Guidance for Off-the-Shelf Software Use in Medical Devices (1999) IV.
- V. Guidance for Industry - Cybersecurity for Networked Medical Devices Containing Off-the Shelf (OTS) Software (2005)
#### PERFORMANCE BENCH TESTING
No new bench testing since K121716.
## CLINICAL TESTING
The performance of TBS iNsight was evaluated via clinical studies covering the following :
- Clinical Aspects FRAX adjusted for TBS ● TBS is an independent clinical risk factor for fracture and can be used in association with WHO's FRAX® to adjust and improve the FRAX® probability of hip fracture and of major osteoporotic fracture in postmenopausal women and in men. This was demonstrated using 3 published studies and a report provided by the Frax group to Medimaps.
- Clinical Aspects TBS iNstats ●
TBS iNsight provides a breakdown of the patients DXA exams based on their BMD and TBS values. The fracture risk is each cell has been evaluated based on a cohort of 29,000 Canadian women. Two studies have been used to demonstrate that the TBS categories of fracture risk computed from the Canadian study are applicable to the US population and another study to demonstrate that the TBS values of the population included in the Canadian study are similar to the normal TBS values of the US population.
- Normative data ●
A US clinical study including Non-Hispanic white US women and men. Non-Hispanic black US women and men and Mexican women and men, aged 20 to 85 years has been conducted. The data provided from the Nhanes IV database, which is the reference database for the US. TBS values obtained for all lumbar vertebral combinations (L1, L2, L3, L4) decreased significantly with age. These decreases seen in lumbar spine TBS reflect the age-related microarchitecture changes at spine.
Based on this clinical studies, no new questions arise regarding the safety and effectiveness of this device, which can be considered substantially equivalent to the predicate devices.
#### CONCLUSION
Medimaps group has demonstrated through the testings that the safety and effectiveness of TBS iNsight is not compromised and that they met all acceptance criteria, demonstrating that it can be considered substantially equivalent to the predicate devices.
