Reverse Shoulder Glenoid Implant Assembly for Cartilage-Like Durability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing articular cartilage implants fail to replicate the unique properties of native hyaline cartilage, leading to durability issues and complications in repairing damaged articular surfaces, necessitating improved implant designs that maximize comfort, minimize damage, and ensure easy installation.
Innovation Solution
A glenoid implant system comprising an anchor, baseplate, and implant is used to repair articular surfaces, where the anchor is secured to the bone, the baseplate is coupled to the anchor, and the implant is secured to the baseplate, utilizing materials like cobalt chromium, stainless steel, titanium, and biocompatible plastics to create a durable and comfortable repair.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional implants are used to repair articular cartilage, then the implant can be installed, but the implant fails to replicate native hyaline cartilage properties leading to durability issues
Solution Approach 1:
The patent changes the material parameters by using cobalt chromium, stainless steel, titanium, or biocompatible plastics instead of traditional materials, allowing the implant to better replicate the mechanical and functional properties of native hyaline cartilage while maintaining durability
Solution Approach 2:
The implant system uses composite construction with an anchor, baseplate, and implant components made from different biocompatible materials, combining the strengths of each material to achieve both durability and cartilage-like functional properties
2Object-affected harmful factors
If implants are designed to maximize patient comfort and minimize damage, then patient outcomes improve, but installation complexity increases
Solution Approach 1:
The implant is divided into separate components (anchor, baseplate, and implant) that can be installed sequentially, allowing for precise positioning and minimizing damage to surrounding tissue while maintaining ease of installation through modular assembly
Solution Approach 2:
The baseplate acts as an intermediary component between the anchor and the implant, facilitating easy installation by providing a stable platform for securing the implant while protecting surrounding bone and tissue structures

AI summary
The present disclosure provides an implant system. The implant system includes an anchor configured to be secured to bone within an excision site formed in a patient's glenoid, said anchor including a shank and an enlarged head. The implant system also includes a baseplate including a body comprising: a bone facing surface; an implant facing surface; and a channel configured to extend radially from an entrance in an outer periphery of said body to a central region of said baseplate, said channel configured to receive said enlarged head and a portion of said shank and including an open region formed, at least in part, in said bone facing surface. The implant system also includes an implant including a body defining a load bearing surface and a baseplate recess, said baseplate recess configured to receive at least a portion of said implant facing surface to said baseplate such that said implant is coupled to said baseplate.
