Devices and methods for altering spinal lateral curvature
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spinal fusion and disc arthroplasty procedures often fail to effectively address severe spinal deformities such as scoliosis and spinal dislocations, while immobilizing the spine and limiting motion.
Innovation Solution
A prosthetic system with independent joint components is implanted between vertebrae, allowing for motion preservation and correction of spinal deformities by reshaping and removing portions of the vertebral endplate and pedicle, with components designed to accommodate varying anatomical positions and orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spinal fusion or disc arthroplasty procedures are performed to treat spinal joints and reduce pain, then pain relief is achieved, but the spine is immobilized and motion is limited
Solution Approach 1:
The prosthetic system employs dynamic articulating joint pairs that allow controlled motion between vertebral bodies. The joint components include articulation surfaces designed to permit rotational and translational movements, enabling the spine to maintain physiological motion while providing structural support and pain relief.
Solution Approach 2:
The prosthetic system divides the spinal joint into separate functional components: upper and lower joint components with independent articulation surfaces. This segmentation allows each component to move relative to the other, preserving spinal motion while distributing mechanical loads effectively for pain relief.
2Stability of the object's composition
If spinal fusion procedures are performed to treat severe spinal deformities, then structural stability is improved, but the ability to correct severe deformities such as scoliosis and spinal dislocations is limited
Solution Approach 1:
The articulating joint pairs provide dynamic stability that can accommodate and correct severe spinal deformities. The joint components are designed to allow controlled movement and adjustment, enabling correction of scoliosis and spinal dislocations while maintaining structural stability during and after the procedure.
Solution Approach 2:
The prosthetic system enables parameter changes in spinal alignment by allowing controlled movement and repositioning of vertebral bodies. The articulation surfaces are designed to facilitate changes in spinal curvature and orientation, enabling correction of severe deformities while maintaining structural integrity.
3Ease of operation
If traditional spinal implants are used to replace spinal discs, then motion preservation is attempted, but the implants cannot accommodate varying anatomical positions and orientations
Solution Approach 1:
The joint components are designed with universal articulation surfaces that can accommodate various anatomical positions and orientations. The upper and lower joint components can be configured to work together in different spinal regions and deformity patterns, providing motion preservation across diverse anatomical scenarios.
Solution Approach 2:
The articulating joint pairs provide movement capabilities in multiple dimensions, allowing the implant to accommodate varying anatomical positions and orientations. The joint design enables rotational and translational movements in different planes, adapting to the complex three-dimensional anatomy of the spine.
