Bone Tie Inserter With Pivoting Head for Facet Joint Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical procedures for addressing degenerative facet joints in the spine, such as vertebral fusion, have high morbidity rates and are not reversible, leading to potential further clinical complications and limited options for unsatisfactory results.
Innovation Solution
A bone tie and bone tie inserter system is provided, comprising a bone tie with a proximal end, distal end, head section, neck section, and fastener section, and a bone tie inserter with an advancer and retriever, designed for securing and fusing facet joints, allowing for adjustable motion restriction and fusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vertebral fusion is performed to address degenerative facet joints, then motion between adjacent vertebrae is stopped and pain is reduced, but morbidity rate increases and the procedure becomes irreversible
Solution Approach 1:
The invention divides the fusion procedure into two distinct stages: a minimally invasive initial stabilization phase using percutaneous implants, and a subsequent optional fusion phase. This segmentation allows patients to benefit from pain reduction immediately while avoiding the high morbidity and irreversibility of traditional fusion, with the option to proceed to fusion only if necessary.
Solution Approach 2:
The invention introduces dynamic adjustability to the treatment process. The initial stabilization implants allow for motion restriction that can be adjusted over time, and the procedure itself is reversible or modifiable. This dynamic approach contrasts with the static, irreversible nature of traditional fusion, allowing treatment to be adapted based on patient response.
2Stability of the object's composition
If vertebral fusion is performed to address degenerative facet joints, then relative motion between vertebrae is stopped, but the procedure is irreversible and limits future treatment options
Solution Approach 1:
The treatment is segmented into optional stages: initial stabilization that provides immediate vertebral stability, followed by an optional fusion stage. This segmentation maintains treatment flexibility because the patient can stop after stabilization if satisfactory results are achieved, or proceed to fusion if additional stability is needed, unlike irreversible traditional fusion.
Solution Approach 2:
The invention provides dynamic treatment adaptability where the level of stabilization can be adjusted. The initial percutaneous implants allow for motion restriction that can be modified over time, and the treatment pathway itself is flexible and reversible, allowing future treatment options to remain available based on patient needs.
3Object-affected harmful factors
If traditional fusion procedures are used, then facet joint motion is restricted, but surgical complexity and morbidity increase
Solution Approach 1:
The invention segments the treatment into a simplified initial stage using percutaneous implants that can be inserted through small incisions, avoiding the complex open surgery required for traditional fusion. This initial stabilization alone can address facet joint pain without requiring the full complexity of traditional fusion procedures.
Solution Approach 2:
The invention introduces percutaneous stabilization implants as an intermediary treatment between non-surgical management and traditional fusion. These implants provide motion restriction and pain relief with minimal surgical intervention, serving as a less complex alternative that can be used alone or as a precursor to fusion if needed.
