Bone Strength Analysis Using Finite Element Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current clinical tests for osteoporosis, such as DEXA and BCT, face challenges in identifying patients at high risk of fracture, particularly those with osteopenia, due to the lack of a credible and robust interventional threshold value for bone strength, which hinders widespread clinical adoption and patient compliance with treatments.
Innovation Solution
A system and method using non-invasive structural analysis of bones from clinical scans, combining finite element analysis with a predetermined interventional threshold value for 'fragile-bone-strength' based on established BMD thresholds, to classify patients and generate intuitive medical reports that enhance patient understanding and treatment adherence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If DEXA or BCT tests are used to identify patients at high risk of fracture, then bone strength assessment is provided, but the lack of credible interventional threshold values limits their widespread clinical adoption
Solution Approach 1:
The patent transforms bone strength assessment from research-only to clinically applicable by changing the parameter framework - establishing specific interventional threshold values (e.g., hip strength < 3000 N, vertebral strength < 4500 N) that convert continuous measurement data into discrete clinical decision points, enabling widespread adoption while maintaining reliability
Solution Approach 2:
The patent introduces finite element analysis as an intermediary computational model that bridges the gap between raw clinical scan data and clinically actionable fracture risk assessment, translating complex biomechanical calculations into standardized threshold-based recommendations that clinicians can universally apply
2Measurement precision
If fracture outcome studies are conducted to establish interventional threshold values, then credible threshold values are obtained, but the process requires extensive time and expense
Solution Approach 1:
The patent performs preliminary computational work by using finite element analysis on existing clinical scan data to establish threshold values before widespread clinical implementation, pre-calculating and validating strength thresholds (e.g., 3000 N for hip, 4500 N for vertebra) so that clinical practitioners can immediately apply these pre-established values without conducting their own fracture outcome studies
Solution Approach 2:
The patent creates a computational model that replicates the complex biomechanical relationships observed in fracture outcome studies, using finite element analysis to copy and simulate the mechanical behavior of bone under various loading conditions, thereby deriving threshold values without requiring actual long-term fracture follow-up studies
3Ease of operation
If only BMD measurements are used for osteoporosis diagnosis, then the test is simple and widely available, but patients with osteopenia are missed despite being at high fracture risk
Solution Approach 1:
The patent combines multiple assessment dimensions - merging traditional BMD measurements with finite element analysis-derived bone strength metrics to create a composite assessment framework that maintains the simplicity of BMD testing while adding the reliability of structural strength analysis, enabling identification of high-risk patients across both osteoporosis and osteopenia ranges
