Bone Fixation Plate With Integrated Projections for Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bone fixation methods, such as single screws or pins, fail to adequately eliminate all degrees of freedom of motion between bones, leading to issues like misalignment, malunion, nonunion, and ongoing pain, while bone plates with numerous screws or pins are impractical and staples have limited compression ability.
Innovation Solution
A fixation device with a plate portion and bone engagement projections that secure bone segments, utilizing a combination of bone engagement projections and fixation apertures to stabilize and compress bone segments, allowing for secure fixation and fusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single screw or pin is used with current bone plates, then the device complexity is reduced, but the fixation reliability is insufficient to eliminate all degrees of freedom of motion
Solution Approach 1:
The patent combines multiple fixation functions into a single integrated device. The bone fixation device integrates a plate portion with multiple bone engagement projections that can simultaneously engage multiple bone segments, eliminating the need for separate screws or pins while providing comprehensive fixation stability.
Solution Approach 2:
The bone fixation device is designed with multi-functionality to address various fixation needs. The plate portion can engage with multiple bone segments through different bone engagement projections, allowing a single device to perform the work of multiple fixation elements while adapting to different bone configurations.
2Reliability
If numerous screws or pins are used to capture bones, then the fixation reliability is improved, but the bone strength is compromised due to fracture or weakening
Solution Approach 1:
The patent consolidates multiple fixation elements into a single plate structure with integrated bone engagement projections. This reduces the number of separate insertion points in the bone, minimizing structural compromise while maintaining fixation reliability through the distributed engagement of multiple bone segments.
3Device complexity
If staples are used for bone fixation, then the device complexity is reduced and profile is lowered, but the compression ability is limited
Solution Approach 1:
The patent merges the simplicity of staple-like structures with the compression capability of plate systems. The bone fixation device features a plate portion with bone engagement projections that can be inserted similarly to staples but provide enhanced compression through the plate's structural design and engagement mechanism.

AI summary
The present disclosure provides devices, systems and methods of bone fixation. The disclosed devices, systems and methods facilitate secure fixation of first and second bone segments, such as to promote fusion thereof. The devices may include at least one bone engagement projection extending from an engagement surface of a plate portion for implantation into the first bone segment. A portion of the plate portion spaced from the at least one bone engagement projection may include at least one bone fixation aperture. The least one bone fixation aperture may allow for a one bone engagement projection to be inserted therethrough and into the second bone segment to affix the plate portion to the second bone segment. In some embodiments, the at least one bone fixation aperture may be a compression slot.
