A Systematic Benchtop Construction and Deconstruction Study of Spinal Ligaments Using Novel 3D Printable Analogue Spine Models

Description

The presentation from the ISTA 2024 conference held in Nashville, revolves around a research study conducted by Siril Teja Dukki[ati, focusing on the development of a benchtop model of the spine using 3D printing technology. Siril begins by discussing the significance of spinal health, highlighting the widespread prevalence of low back pain and its considerable economic impact. He outlines the limitations of existing research approaches such as cadaveric studies and finite element models, which have not fully addressed the nuances of spine biomechanics.



Siril proposes a novel approach to create anatomically and biomechanically accurate 3D models of the spine, aiming to provide a reliable, affordable alternative for research and surgical training. He describes the method of constructing these models from 3D MRI images, emphasizing the flexibility of 3D printing to create customizable components, including ligaments, which can be tested for their effect on spine stiffness.



The presentation details the experimental setup used to quantify the biomechanical properties of the spine models, revealing that the 3D printed spine can effectively mimic natural spine behaviors in five out of six tested directions, although some discrepancies in extension require further investigation. Siril presents data comparing stiffness variations with differing configurations of ligaments and damage to the model, discussing the implications of these results for understanding spinal mechanics and potential injury responses.



Siril concludes by summarizing the findings and the necessity for further research, opening the floor for questions from the audience regarding the materials used in 3D printing, exposure times, and overall costs. He emphasizes that this innovative approach to spinal modeling has the potential to advance both clinical practice and scientific discovery.
