Overview
BoneMetrics US is a fully automated radiological image processing software device developed by Gleamer SAS. It is specifically intended to aid healthcare professionals, particularly radiologists, in the measurement of Cobb angles on frontal spine radiographs. The tool is designed for individuals aged 4 years and older who have suspected or present spinal deformities, such as scoliosis. By using machine learning techniques, BoneMetrics US automatically identifies keypoints corresponding to the corners of vertebrae and calculates all possible angles, retaining Cobb Angles above 7°. This automation aims to reduce variability and save time in orthopedic measurements. The software generates result files in DICOM format and is designed to integrate seamlessly into existing PACS/RIS workflows. It should be used as an aid and not as a replacement for full patient evaluation or as the sole basis for diagnosis.

What Physicians Need to Know
Evidence Base
BoneMetrics US is an AI-powered solution designed to assist radiologists in detecting and quantifying bone lesions and measuring Cobb angles on frontal spine radiographs. It incorporates reference value thresholds for over 30 measurements, displaying them directly within the secondary capture alongside their original sources. This allows radiologists to assess if a measurement falls within the expected range without consulting external references. The software uses deep learning techniques to analyze radiographs.
Clinical Validation Studies
BoneMetrics US received 510(k) clearance from the FDA on February 5, 2025. A Clinical Standalone Performance Study was conducted on a dataset of 345 frontal spine radiographs from children and adults in the US to validate its performance. The ground truth for this study was established by two US board-certified musculoskeletal radiologists and one US board-certified orthopedic surgeon. Another study compared BoneMetrics' measurements of pelvic and hip parameters on AP and false profile radiographs to expert manual measurements, showing excellent agreement with intraclass correlation coefficient (ICC) values above 0.97 for all parameters. A retrospective study on full-leg standing radiographs found mean absolute error values for various measurements (e.g., hip-knee-ankle angle, leg length) and excellent agreement with gold-standard measurements (ICC > 0.97). BoneMetrics has been shown to reduce annotation time by 93% across all measurements.
Alert Fatigue Management
While not explicitly detailed for BoneMetrics, the broader Gleamer AI Copilot platform aims to reduce errors from fatigue and search biases. BoneMetrics generates structured reports and overlays measurements directly onto DICOM images, which can streamline the review process and potentially mitigate fatigue associated with manual measurements. The system flags AI findings directly within PACS and can prioritize positive cases in the worklist, helping radiologists focus on critical findings.
Differential Diagnosis Support
BoneMetrics US is intended to aid users in the measurement of Cobb angles on frontal spine radiographs for patients with suspected or present spinal deformities, such as scoliosis. It should not be used as a replacement for full patient evaluation or as the sole basis for diagnosis.
Clinical Workflow Integration
BoneMetrics US is designed to integrate seamlessly into existing PACS/RIS workflows. It can be deployed via cloud, on dedicated local hardware, or as a virtualized local instance. Analysis is triggered automatically after image acquisition. The software generates result files in DICOM format, consisting of annotated images with measurements plotted as an overlay and angle values displayed in degrees. Gleamer's AutoReport feature, compatible with BoneMetrics, automatically generates structured reports with AI findings, pre-filling techniques, and smart impressions, integrating directly into RIS/PACS/Reporter environments. Gleamer Copilot flags AI findings directly in PACS and prioritizes positive cases in the worklist.
Decision Audit Trail
BoneMetrics US generates result files in DICOM format, which include annotated images with measurements and angle values. It does not alter the original images or change their order.
Physician Tip
BoneMetrics US is a tool to assist in measuring Cobb angles for spinal deformities and other musculoskeletal measurements. It is not a standalone diagnostic tool and should be used in conjunction with full patient evaluation. The integration with PACS/RIS and automated reporting can help streamline your workflow and reduce manual measurement time. Pay attention to the AI findings flagged in your PACS and how they prioritize your worklist, as this can help focus on critical cases.
BoneMetrics US integrates seamlessly into existing PACS/RIS workflows. It can be deployed via cloud, on dedicated local hardware, or as a virtualized local instance. The software connects to DICOM sources/destinations, such as PACS, and automatically processes radiographs. Gleamer's AutoReport feature integrates with RIS/PACS/Reporter environments for automated report generation. The Gleamer Copilot flags AI findings directly in PACS.

What the Web Says
BoneMetrics (US) by Gleamer.ai is an AI-powered software designed to automate orthopedic measurements from X-rays, aiming to reduce variability and save time for healthcare professionals. It provides automated measurements for various anatomical landmarks and angles, including Cobb angles for spinal deformities, and measurements on lower limb, forefoot, and lateral foot radiographs. The software is intended to assist radiologists and other healthcare professionals in their daily practice by providing accurate and standardized measurements.
Overall: PositiveStrengths
- Automates over 30 orthopedic measurements, reducing manual annotation time by up to 93%.
- Enhances standardization and reproducibility of measurements, with excellent agreement with expert manual measurements (ICC values above 0.97 for many parameters).
- Reduces variability in measurements and provides reference values directly within the display for quick assessment.
- Aids in the diagnosis and assessment of spinal deformities like scoliosis by automating Cobb angle measurements.
- Can be deployed on cloud and integrated with existing PACS and X-ray imaging platforms.
- Potential to improve efficiency and patient care by allowing radiologists to focus on higher-value clinical decisions.
Limitations
- Some Reddit users express general skepticism about AI in radiology, citing instances of false positives or AI missing clinically significant findings.
- One Reddit user mentioned that Gleamer AI (likely referring to BoneView, another Gleamer product) sometimes picks up "ghost fractures" on kids' X-rays, leading to unnecessary reassurance for ED doctors.
- The software is intended as an aid and should not be solely relied upon for diagnosis or used instead of full patient evaluation.
- While studies show high accuracy, real-world clinical integration and user experience can vary.
- Some AI tools in radiology, in general, have been noted to have limitations in complex cases or with subtle findings.
