Universal Monolithic Patellar Plate with Detachable Tabs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fracture reduction systems for the patella require customization and the use of wires to create tension, which can be time-consuming and challenging, especially in areas with curvature and tight skin coverage.
Innovation Solution
A universal, monolithic patellar plate system with detachable tabs and a curved perimeter plate that can be contoured to fit any patella, eliminating the need for wire tension and allowing for secure attachment without individual patient fitting, using a strong and flexible titanium alloy material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If high tension mesh plates are used for patella fracture reduction, then fracture fixation can be achieved, but the system requires the surgeon to cut the mesh plate to size and fit it for each individual patient, increasing operational time and complexity
Solution Approach 1:
The patent applies universality by designing a standardized mesh plate system that can be used across multiple patients without customization. The plate features a universal configuration with multiple hole patterns and attachment points that accommodate various fracture types and patella sizes, eliminating the need for pre-operative planning or intraoperative cutting and fitting while maintaining adaptability to individual patient needs
2Strength
If wiring or cabling systems are used to create tension across the fracture, then fracture reduction can be achieved, but the system requires routing wires through channels created in the patella or wrapping wires around the patella, increasing procedural complexity
Solution Approach 1:
The patent extracts the wire routing complexity by eliminating the need for channels and wrapping procedures. Instead, the system uses a mesh plate with pre-configured attachment holes that directly engage with screws or other fixation elements, removing the intermediate steps of creating channels and routing wires while maintaining the necessary tension and fixation strength across the fracture
3Strength
If a monolithic plate is used for fracture reduction, then the system can provide strong fixation, but the plate may not accommodate various patella sizes and shapes without customization
Solution Approach 1:
The patent applies segmentation by dividing the monolithic plate into functional zones with multiple hole patterns and attachment points. The plate maintains a single-piece construction for strength while incorporating varied hole configurations, spacing options, and attachment mechanisms that can be selectively used depending on the specific fracture pattern and patella geometry, enabling universal application without compromising fixation strength
