Hinged Osteotomy Implant for Adjustable Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current high tibial osteotomy implants are costly and complex due to their custom nature, requiring specific anatomical modeling, and lack a simplified, cost-effective solution that can be adjusted to fit individual patient anatomy effectively.
Innovation Solution
The development of an osteotomy implant comprising a porous portion, a solid portion, and a hinge portion, allowing the implant to be adjusted from a first configuration to a second, utilizing biocompatible materials like titanium and PEEK, with features such as 'U' shaped load-bearing designs and flexible hinges for compression and expansion to fit various osteotomy sites.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If custom-modeled implants are used to fit patient anatomy, then the fit and stability are improved, but the cost and manufacturing complexity increase
Solution Approach 1:
The implant is divided into multiple standardized segments or blocks that can be selectively combined. Each segment has standardized interfaces but can be configured in different arrangements to match various patient anatomies, reducing the need for fully custom manufacturing while maintaining adaptability.
Solution Approach 2:
The implant includes adjustable components such as modular wedges or repositionable elements that allow post-manufacturing adjustment to fit specific patient anatomies. This dynamic adjustability provides customization without requiring custom manufacturing for each patient.
2Adaptability or versatility
If custom-modeled implants are used to fit patient anatomy, then the fit and stability are improved, but the production cost increases
Solution Approach 1:
A set of standardized implant components is designed to serve multiple patient anatomies through different combinations and configurations. This universal design allows a single manufacturing process to produce components that can be adapted to various patients, reducing per-unit cost while maintaining anatomical fit.
Solution Approach 2:
The implant system uses standardized components with variable parameters (such as different wedge angles, thicknesses, or geometries) that can be selected and combined to match specific patient needs. This approach allows cost-effective manufacturing of standardized parts while providing anatomical customization through parameter selection rather than custom manufacturing.
3Ease of manufacture
If standardized implants are used to reduce cost and complexity, then the ease of manufacture is improved, but the adaptability to patient anatomy decreases
Solution Approach 1:
The implant is divided into multiple standardized segments or blocks that can be selectively combined. Each segment has standardized interfaces but can be configured in different arrangements to match various patient anatomies, reducing the need for fully custom manufacturing while maintaining adaptability.
Solution Approach 2:
The implant includes adjustable components such as modular wedges or repositionable elements that allow post-manufacturing adjustment to fit specific patient anatomies. This dynamic adjustability provides customization without requiring custom manufacturing for each patient.

AI summary
An osteotomy implant including a porous portion, a solid portion, and a hinge portion. The porous portion includes a first part and a second part that defines a clearance therebetween. A solid portion abuts the porous portion. A hinge portion of the solid portion is coupled to the first part and the second part. The hinge portion is configured to enable the implant to be changed from a first configuration to a second configuration.
