Pivoting Clavicle Plate Insert for Adjustable Bone Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bone implants, particularly for clavicle fractures, face challenges in temporary fixation, difficulty in connecting plates to bones, and inflexibility in adapting to patient anatomy.
Innovation Solution
A kit comprising a plate and an insert with a pivoting mechanism, allowing for flexible anchoring and connection via screws or sutures, with contoured shapes for precise alignment and adjustable orientation, and a recess for tool reception to enhance stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plate is used for bone treatment with traditional fixation methods, then the bone can be fixed, but the implantation is difficult and error-prone
Solution Approach 1:
The insert is designed to be rotatable within the receptacle of the plate, allowing dynamic adjustment of the anchoring angle and position. This rotational freedom enables the surgeon to optimize the insertion angle for the screw or thread into the bone, making the implantation process easier and more reliable without requiring precise pre-planning
Solution Approach 2:
The implant system is divided into separate components: a plate with a receptacle, and a separate insert that can be independently positioned and rotated. This segmentation allows the insert to be adjusted to the optimal orientation before final fixation, improving both ease of operation and reliability
2Adaptability or versatility
If a plate with fixed anchoring is used, then the structure is simple, but the adaptability to patient anatomy is limited
Solution Approach 1:
The rotatable insert provides dynamic adaptability to match the specific anatomy of different patients. The insert can be rotated to achieve the optimal insertion angle for the screw or thread, allowing the same implant design to adapt to varying bone geometries and fracture patterns without increasing the basic structural complexity
Solution Approach 2:
The receptacle design universally accommodates inserts with different rotational positions, and the insert itself can serve multiple functions depending on its rotational orientation. This multi-functionality allows a single implant design to adapt to various anatomical configurations
3Adaptability or versatility
If traditional bone screw connection is used, then the fixation is stable, but the flexibility in connection is limited
Solution Approach 1:
The rotatable insert allows the connection angle and direction to be dynamically adjusted during implantation. The surgeon can rotate the insert to achieve the optimal angle for screw or thread insertion into the bone, providing connection flexibility while maintaining fixation stability through proper angular optimization

AI summary
The invention relates to a kit comprising at least one insert (10, 20) and a plate (1) for treating a bone, specifically a clavicle (B). The plate (1) has a receptacle (6) for the insert (10, 20). The insert (10, 20) has an outer contour (C″) and/or the receptacle (6) has an inner contour (C), wherein the outer contour (C″) and the inner contour (C) fit each other such that the insert (10, 20) inserted into the receptacle (6) can pivot about an axis which runs substantially parallel to a plate top side (0).
