This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,427.

Summary of the Inventive Concept

The present inventive concept relates to improved shoulder prostheses with self-adjusting mechanisms, integrated sensors, and modular components, enabling optimized humeral component alignment, real-time joint stress monitoring, and fine-tuned adjustments during and after surgical implantation.

Background and Problem Solved

The original patent disclosed shoulder prostheses with stemless humeral components and stemmed humeral components. However, these prostheses often require manual adjustments during surgical implantation, which can lead to inaccurate alignment and increased wear and tear on the joint. The present inventive concept addresses these limitations by introducing adaptive alignment mechanisms, integrated sensors, and modular components to enhance the accuracy and efficiency of shoulder prostheses.

Detailed Description of the Inventive Concept

The new inventive concept comprises a system for shoulder prostheses with stemless humeral components and stemmed humeral components, featuring a self-adjusting mechanism for optimizing humeral component alignment during surgical implantation. This mechanism utilizes an integrated sensor to monitor joint stress and adjust the component's position accordingly. Additionally, the inventive concept includes a modular humeral component with interchangeable stem modules, enabling adaptation to varying patient anatomies. Furthermore, a humeral component with an integrated micro-adjustment mechanism allows for fine-tuned adjustments to the component's position during and after surgical implantation. The inventive concept also encompasses a smart implant with real-time monitoring and feedback capabilities for optimizing joint function and reducing wear and tear.

Novelty and Inventive Step

The new claims introduce novel features such as self-adjusting mechanisms, integrated sensors, and modular components, which are not present in the original patent. These features enable optimized humeral component alignment, real-time joint stress monitoring, and fine-tuned adjustments during and after surgical implantation, thereby providing a significant improvement over the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include variations of the self-adjusting mechanism, such as using artificial intelligence or machine learning algorithms to optimize humeral component alignment. Other variations could include different modular component designs or alternative materials for the humeral component. These alternative embodiments would ensure broad conceptual coverage and adaptability to diverse patient needs.

Potential Commercial Applications and Market

The present inventive concept has significant commercial potential in the orthopedic industry, particularly in the field of shoulder prostheses. The improved accuracy and efficiency of the inventive concept could lead to increased adoption and market share, as well as expansion into new markets and patient populations.
