Shoulder Implants Altering Force Vectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for osteoarthritis, such as joint replacement and invasive surgeries, fail to effectively address the pain and mobility issues caused by unbalanced force distribution in joints like the shoulder, leading to significant trauma and limited therapeutic outcomes.
Innovation Solution
The use of selectively placed implants that displace targeted connective and muscle tissues around the joint to realign force vectors and alter moment arms, reducing load on affected areas without cutting bones and with minimal tissue cutting, thereby achieving therapeutic effects like pain relief and enhanced cartilage regeneration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional surgical interventions (joint replacement, invasive surgeries) are used to treat osteoarthritis, then pain relief and mobility improvement can be achieved, but significant trauma and tissue damage occur
Solution Approach 1:
The patent introduces implants as intermediary elements that are placed within the joint space to modify force distribution. These implants act as mediators between the bone surfaces, redistributing loads away from damaged cartilage regions without requiring removal of bone or extensive tissue disruption. The implants serve as a bridge that alters biomechanics while preserving surrounding tissues.
Solution Approach 2:
The patent changes the biomechanical parameters of the joint by introducing implants that alter force vectors, moment arms, and load distribution patterns. By modifying these mechanical parameters rather than the physical structure of bones and soft tissues, the treatment achieves therapeutic effects with minimal trauma.
2Reliability
If force redistribution is achieved through tissue displacement, then joint loading is reduced and pain is alleviated, but the procedure becomes more complex
Solution Approach 1:
The patent divides the implant system into separate components including bone anchors, implants, and soft tissue interaction elements. This segmentation allows for modular placement and adjustment, enabling complex force redistribution functions to be achieved through coordinated action of simpler, separately placed components rather than a single complex device.

AI summary
Selectively placed implants are specifically configured and dimensioned to address pathologies of the shoulder joint arising from improper force distribution. By using appropriately sized and positioned implants as described herein, displacement of targeted connective and muscle tissues acting on the shoulder is accomplished in order to realign force vectors and/or alter moment arms loading the joint to achieve therapeutic effects without cutting bone and with minimal cutting of the connective tissues.
