Spinal Fixation Selective Bone Growth Agent Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current spinal fixation systems lack the ability to selectively apply bone growth promoting agents, which are essential for enhancing fusion and healing processes, leading to inadequate integration of implants with bone tissue.
Innovation Solution
The development of a spinal fixation system that incorporates a bone growth promoting agent applied to various components such as screws, rods, and plates, allowing for selective application to specific regions or patterns to stimulate bone growth and fusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bone growth promoting agents are applied to spinal fixation devices, then bone integration and fusion are enhanced, but device complexity increases due to selective application requirements
Solution Approach 1:
The patent applies bone growth promoting agents to specific regions of the spinal fixation devices rather than uniformly across all surfaces. The agent is selectively applied to regions where bone contact and fusion are desired, such as the outer surface of rods and specific areas of screws and plates, while leaving other regions untreated. This localized application enhances bone integration at critical interfaces without requiring complex delivery systems for the entire device.
2Reliability
If bone growth promoting agents are selectively applied to specific regions, then fusion is promoted, but manufacturing precision requirements increase
Solution Approach 1:
The bone growth promoting agent is applied to the spinal fixation devices during the manufacturing or pre-processing stage, before the devices are implanted. This preliminary application allows for controlled and precise placement of the agent on specific surfaces and regions of the devices. The agent can be applied to rods, screws, and plates in advance, ensuring consistent and accurate distribution at the intended locations without requiring complex application mechanisms during surgery.
