Spinal Column Stability Assessment Using Virtual Decompression Simulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for assessing spinal column integrity after decompression procedures are subjective, time-consuming, and lack objective data, making it difficult to predict and prevent iatrogenic instability.
Innovation Solution
A method that involves receiving image data of the spinal column, determining the material strength of bony anatomy, simulating the removal of bony anatomy or soft tissue to assess stability, and comparing preoperative and postoperative stability assessments to predict the risk of iatrogenic instability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional methods (surgeon's prior experience, knowledge, and judgment) are used to assess spinal column integrity, then the assessment can be completed, but the method is time consuming, subjective, complex, and may not be recorded for future reference
Solution Approach 1:
The patent replaces the mechanical/cognitive system of surgeon's subjective judgment with an automated image processing and analysis system that objectively measures spinal column integrity parameters from medical images, eliminating time-consuming manual assessment while providing precise, quantifiable results
Solution Approach 2:
The patent creates a digital replica or model of the spinal column from medical images, allowing virtual assessment and simulation of surgical procedures without requiring repeated physical examinations, thereby saving time while maintaining assessment accuracy
2Object-affected harmful factors
If decompression procedures are performed to relieve spinal compression, then neural element compression is reduced, but the integrity, stability, and mobility of the spinal column may be negatively affected
Solution Approach 1:
The patent performs preoperative virtual simulation of decompression procedures on digital models of the patient's spinal column to predict potential stability issues before actual surgery, allowing surgeons to plan procedures that minimize iatrogenic instability while still achieving decompression relief
Solution Approach 2:
The patent provides quantitative feedback on spinal column stability metrics before and after simulated decompression procedures, enabling surgeons to adjust surgical plans to maintain optimal stability while achieving necessary decompression of neural elements
3Reliability
If multiple stability assessments are completed (preoperative and postoperative simulation), then the risk of iatrogenic instability can be predicted, but the complexity of the assessment process increases
Solution Approach 1:
The patent implements a universal assessment platform that handles multiple functions including preoperative planning, intraoperative decision-making, and postoperative evaluation using the same image processing and analysis tools, reducing overall system complexity despite performing multiple assessments
Solution Approach 2:
The patent combines multiple assessment functions and analysis tools into an integrated software system that automatically performs sequential assessments and consolidates results, reducing the complexity burden on users while maintaining comprehensive evaluation capabilities

AI summary
A method of assessing spinal column stability involves receiving image data corresponding to a spinal column of a patient; determining, based on the image data, a material strength of bony anatomy in at least a portion of the spinal column; completing a first stability assessment of the spinal column, based at least in part on the determined material strength; modifying the image data to simulate removal of bony anatomy or soft tissue from the spinal column to yield modified image data; and completing a second stability assessment of the spinal column, based at least in part on the determined material strength and the modified image data.
