Synthetic Foot Osteotomy Implants with Struts for Revision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current osteotomy procedures using allograft or autograft bone implants make it difficult to distinguish between the implanted bone and the patient's own bone, complicating revision surgeries due to integration issues.
Innovation Solution
The development of an osteotomy system comprising implants with unique features such as struts and spikes for integration and removal, along with insertion instruments, fastener guides, and resection guides, allowing for non-allograft or non-autograft bone implants that facilitate easier insertion and potential removal during revision surgeries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If allograft or autograft bone implants are used, then bone integration is achieved, but it becomes difficult to distinguish between the implanted bone and the patient's own bone during revision surgery
Solution Approach 1:
The implant is made from synthetic bone material that can be differentiated from natural bone through color, density, or other visual characteristics. This allows surgeons to easily identify the synthetic implant during revision surgery while still achieving effective bone integration through osteoconductive surfaces and porous structures.
2Ease of operation
If synthetic bone implants with unique features are used, then easier identification and removal during revision surgery is enabled, but the complexity of the implant structure increases
Solution Approach 1:
The synthetic bone implant is designed as a modular structure with distinct components including a body portion, fixation elements, and identification features. This segmentation allows for easier removal during revision surgery while maintaining structural integrity during normal use.
Solution Approach 2:
The implant incorporates intermediate features such as threaded holes, removal tools, or marker elements that facilitate easier extraction without requiring complex surgical procedures. These intermediary elements act as mediators between the implant and surgical instruments.
3Ease of repair
If non-allograft or non-autograft bone implants are used, then easier removal during revision surgery is possible, but bone integration capability must be maintained
Solution Approach 1:
The synthetic bone implant utilizes porous or lattice structures that promote bone ingrowth and osseointegration while maintaining the ability to be removed if needed. The porous architecture allows bone tissue to penetrate and anchor to the implant surface, providing reliable integration without compromising future removability.
Solution Approach 2:
The implant is constructed from composite materials that combine synthetic bone substitutes with surface treatments or coatings that enhance bone bonding. This composite approach ensures strong integration with patient bone while the underlying synthetic structure remains removable through designed access points or features.
