Advancing Bone Health Research: How IAG Helped Redefine Imaging-Based Assessment of Bone Integrity

Advancing Bone Health Research: How IAG Helped Redefine Imaging-Based Assessment of Bone Integrity
Marie Fussel

Advancing bone health research requires imaging endpoints that can truly capture how bone heals, not just whether a fracture line has disappeared. In this case study, Image Analysis Group describes how its experts co‑developed and validated an extended Lane and Sandhu Scoring System (eLSS) to quantify bone formation, union, and remodeling in complex orthopedic trials, using centralized radiograph and CT review on the DYNAMIKA platform to deliver sensitive, regulator‑ready bone integrity endpoints for sponsors developing next‑generation osteogenic and regenerative therapies.

Advancing Bone Health Research: How IAG Helped Redefine Imaging-Based Assessment of Bone Integrity


Accurately assessing bone healing and structural integrity remains one of the most persistent challenges in orthopedic and bone health research. While innovative therapies, from osteogenic implants to regenerative cell-based approaches, are rapidly advancing, imaging endpoints have struggled to keep pace. Traditional radiographic scoring systems are often narrow in scope, inconsistently applied, or insufficiently sensitive to capture meaningful changes in bone formation, union, and remodeling over time.

A newly published study now marks an important step forward. Through the development, standardization, and validation of a novel imaging-based scoring system, Image Analysis Group (IAG) has helped establish a more robust, reproducible approach to evaluating bone integrity and therapeutic impact in clinical trials, reinforcing its position as a leading imaging CRO and trusted scientific partner in bone health research.

The Need for Better Bone Imaging Endpoints


Bone healing is a dynamic, multidimensional process involving new bone formation, mechanical stability, and progressive remodeling. Yet many existing scoring systems focus on a single aspect of healing or are limited to specific fracture types. In trials evaluating advanced osteogenic therapies, this creates a critical gap: promising drug or device effects may go undetected simply because the tools used to measure them are inadequate.

Recognizing this unmet need, IAG collaborated with clinical and industry partners to design and deploy an extended, imaging-based scoring framework capable of capturing the full continuum of bone repair. The result is a refined system that builds on established methodology while addressing real-world limitations encountered in modern clinical trials.

Developing a New Standard for Bone Integrity Assessment


In the recently published study, IAG led the imaging strategy for a longitudinal trial evaluating bone healing in complex orthopedic indications, including congenital pseudoarthrosis and recurrent osseous non-union. Central to the study was the development of the extended Lane and Sandhu Scoring System (eLSS), a radiograph- and CT-based tool designed to better reflect contemporary therapeutic mechanisms and imaging realities.

Unlike traditional approaches, the eLSS explicitly differentiates between:

  • Bone formation across the longitudinal defect,
  • Bone union across the transverse plane, and
  • Bone remodeling, assessed through the emergence of continuous cortical and trabecular architecture.

This nuanced framework allowed investigators to evaluate not just whether bone was healing, but how it was healing over time, an essential distinction when assessing advanced regenerative or cell-based therapies.

From Methodology to Trial Deployment


As an imaging CRO, IAG’s role extended well beyond scoring system design. The organization oversaw end-to-end imaging execution, including protocol alignment, longitudinal image handling, blinded expert reads, and adjudication workflows. Using IAG’s proprietary DYNAMIKA platform, expert musculoskeletal radiologists conducted independent reads across more than 200 radiographic and CT scans, ensuring consistency and traceability throughout the trial.

The results speak to the rigor of the approach. The novel scoring system demonstrated moderate to excellent interobserver agreement across imaging modalities, pathologies, and assessment types, validating its reliability in real-world clinical trial conditions. Importantly, this level of agreement was maintained even in anatomically complex scenarios, such as cross-union assessment, where conventional scoring systems often fall short.

Why This Matters for Sponsors and Developers


For sponsors developing therapies in bone health, orthopedic surgery, and regenerative medicine, this publication carries significant implications. Reliable, sensitive imaging endpoints are essential for:

  • Demonstrating treatment efficacy in small or heterogeneous populations
  • Supporting dose-response and mechanism-of-action analyses
  • Strengthening regulatory submissions and peer-reviewed publications

By enabling standardized, reproducible assessment of bone integrity across time and modality, the new scoring framework helps reduce uncertainty and enhances confidence in trial outcomes.

IAG’s Role as a Strategic Imaging Partner


This bone health research publication reinforces Image Analysis Group’s position as more than a service provider. IAG operates at the intersection of imaging science, clinical trial operations, and therapeutic innovation, partnering with sponsors to solve complex endpoint challenges that directly impact development success.

With deep expertise in musculoskeletal imaging, quantitative analysis, and reader-based methodologies, IAG continues to support trials across orthopedics, rheumatology, and bone metabolism. Its ability to co-develop novel scoring systems, validate them scientifically, and operationalize them at scale sets IAG apart in an increasingly data-driven clinical research landscape.

Shaping the Future of Bone Health Trials


As the pipeline of bone-targeted therapies grows, so too does the need for imaging endpoints that reflect modern science. The newly published scoring system represents a meaningful advance toward that goal, and a model for how imaging CROs can actively shape the future of clinical research.

Through innovation, collaboration, and scientific rigor, Image Analysis Group is helping ensure that breakthroughs in bone health are not only developed, but accurately measured, understood, and brought to patients with confidence.
