Foot Bone Plate with Lateral Flange for Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foot bone plates require additional instrumentation for compression and often rely on bone screws for fixation and compression, resulting in minimal compression through the plate itself, necessitating a solution that integrates both fixation and compression capabilities.
Innovation Solution
A foot bone plate with a plurality of bores for receiving bone screws on both sides and a lateral flange to hold a bone screw across the bone juncture, providing simultaneous fixation and compression through a combination plate and screw unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If prior art foot bone plates are used with added instrumentation, then compression can be achieved, but device complexity increases
Solution Approach 1:
The patent combines the compression function and fixation function into a single integrated bone plate structure. The plate includes multiple bores for fixation screws and a specialized compression bore that accepts a compression screw, eliminating the need for separate compression instruments while providing both compression and fixation capabilities through one device
Solution Approach 2:
The bone plate is designed to perform multiple functions: it provides fixation through multiple bores that accept screws for securing bone portions, and simultaneously provides compression through a specialized compression bore that accepts a compression screw. This multi-functional design eliminates the need for separate instrumentation
2Stability of the object's composition
If bone screws are used for fixation and compression, then fixation is achieved, but compression through the plate is minimal
Solution Approach 1:
The bone plate is segmented into multiple functional zones with different bore configurations. The plate has multiple bores for fixation screws on both sides of the bone juncture, and a separate compression bore positioned to receive a compression screw that extends through the plate to apply compression force, allowing independent optimization of fixation and compression functions
3Stability of the object's composition
If a plate bridges the joint between two bones, then fixation is provided, but additional instrumentation is required for compression
Solution Approach 1:
The patent merges the compression capability directly into the bone plate structure by including a compression bore that accepts a compression screw. This integration allows the plate to provide both alignment stability through its bridging function and compression through the built-in compression screw, eliminating the need for additional compression instrumentation

AI summary
A foot bone plate provides both fixation of two bones or bone portions and compression across their juncture. The foot bone plate has a plurality of bone screw bores positioned to receive and hold a bone screw on both sides of the two bones/bone portions (i.e. fixation), and a lateral flange positioned to receive and hold a bone screw across the foot bones/foot bone portions juncture (i.e. compression). The foot bone plate has an elongate body having a plurality of bores along its length configured to receive and hold a bone screw generally perpendicular to the foot bone plate and into the two foot bone portions. A flange is positioned at a side of the plate and includes a bore to receive and hold a bone screw. The flange and flange bore positions and holds the bone screw such that it extends through the juncture of the two bones/bone portions.
