Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented glenoid implants with discrete augment angles often result in excessive bone removal, improper fit, implant loosening, and decreased function, leading to surgical complications and limited customization for individual patient needs.
Innovation Solution
An infinitely adjustable augment angle baseplate that allows for precise customization of implant position and orientation through a pivot hinge design, enabling surgeons to achieve optimal joint alignment and stability, reducing the need for multiple implant options and minimizing surgical errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If discrete augment angles are used in current augmented glenoid implants, then manufacturing and inventory are simplified, but customization for individual patient needs is limited and improper fit occurs
Solution Approach 1:
The baseplate incorporates a pivot hinge mechanism that transforms a static, fixed-angle implant into a dynamic, adjustable one. The hinge allows the baseplate to rotate and adapt to various augment angles intraoperatively, enabling customization for each patient's anatomical requirements while maintaining a single standardized implant design for manufacturing.
Solution Approach 2:
The invention changes the key parameter of augment angle from a fixed discrete value to a continuously adjustable parameter. By incorporating the pivot hinge, the baseplate can be positioned at different angles during surgery, allowing surgeons to optimize the implant orientation for each patient's specific anatomical conditions without requiring multiple pre-manufactured angle variants.
2Quantity of substance
If discrete augment angles are used in current augmented glenoid implants, then inventory management is simplified, but excessive bone removal and implant loosening occur due to improper fit
Solution Approach 1:
The single baseplate design with pivot hinge serves multiple functions: it can be positioned at various augment angles to accommodate different patient anatomies, eliminates the need for multiple angle-specific implants, and provides a universal solution that reduces inventory complexity while improving fit accuracy and implant stability.
Solution Approach 2:
The dynamic adjustment capability allows the implant to achieve proper fit for each patient's anatomy, preventing excessive bone removal and reducing the risk of implant loosening by ensuring optimal positioning rather than forcing a fixed-angle implant into a non-ideal configuration.
3Productivity
If fixed augment angle baseplates are used, then surgical procedure is faster, but surgical errors increase due to limited adjustment options
Solution Approach 1:
The pivot hinge provides controlled adjustability that allows surgeons to make precise alignment corrections during surgery. This dynamic adjustment capability reduces surgical errors by enabling fine-tuning of the implant position while maintaining a relatively efficient surgical workflow compared to using multiple pre-fabricated angle options.

AI summary
A system for an anatomical total shoulder arthroplasty or reverse total shoulder arthroplasty can include an infinitely adjustable augment angle baseplate, an implant, a baseplate, an engagement member, and a prosthetic head. The infinitely adjustable augment angle baseplate can be configured to be secured to a first bone of a patient. The implant can be insertable into a second bone of a patient. The baseplate can be insertable into the implant and configured to be attached to the second bone of the patient. The engagement member can be couplable to either of the infinitely adjustable augment angle baseplate or the baseplate. The prosthetic head can be couplable to the other of the infinitely adjustable augment angle baseplate or the baseplate. The prosthetic head can be engageable with the engagement member to form a prosthetic joint between the first bone and the second bone.
