Cable Button Bone Plate Fixation Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bone fracture reduction methods using bone plates and screws may not provide adequate compression and stability, particularly in complex fracture cases, as they rely on screw placement which can be inconsistent and may not fully address the need for precise alignment and compression.
Innovation Solution
A cable button system integrated with a bone plate and cerclage wire, where the cable button has threaded apertures to secure the cerclage wire, allowing for multiple passage orientations and enhanced stability by compressing the fracture site effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw placement is used to secure bone plate to bone, then bone fixation is achieved, but compression and stability are insufficient particularly in complex fracture cases
Solution Approach 1:
The cable button serves as an intermediary device between the cerclage wire and the bone plate. It provides a standardized interface that guides the wire through the bone plate, ensuring consistent positioning and compression force application without relying on variable screw placement techniques.
Solution Approach 2:
The invention changes the fixation method from mechanical screw insertion to a wire-based system with controlled tension. By applying tension to the cerclage wire and securing it to the cable button, the system achieves compression through parameter control (wire tension) rather than relying on screw thread engagement variability.
2Strength
If multiple screws are used to secure bone plate, then fixation strength is improved, but the complexity of the procedure increases
Solution Approach 1:
The cable button integrates multiple functions into a single component: it anchors the cerclage wire, provides attachment to the bone plate, and maintains compression force. This merging of functions reduces the number of separate components and steps compared to using multiple screws for similar purposes.
3Object-affected harmful factors
If cerclage wire is used alone for fracture reduction, then soft tissue preservation is improved, but compression and stability are inadequate
Solution Approach 1:
The system combines different materials and mechanisms: the flexible cerclage wire for soft tissue compatibility with the rigid cable button and bone plate for structural stability and compression. This composite approach leverages the advantages of each component - the wire's tissue friendliness and the button/plate's mechanical strength.
