Dual Screw Sacral Plate for Spinal Fusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical treatments for spinal disorders, such as scoliosis and degenerative disc disease, often require complex procedures and multiple steps, which can increase operating time and radiation exposure during implantation of spinal constructs, and may not provide adequate stability or prevent implant backout.
Innovation Solution
A spinal implant system featuring a dual screw sacral plate with angular orientations and a multi-axial fastener system, including a plate with cavities for secure attachment to the sacrum and ala regions, utilizing awls and inserts to stabilize the plate and prevent backout, along with a method for implanting components using surgical navigation to reduce procedural steps and patient repositioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex surgical procedures with multiple steps are used for implantation, then implant stability and security are improved, but operating time and radiation exposure increase
Solution Approach 1:
The patent combines multiple implantation functions into a single integrated sacral plate system. The plate integrates both midline screw reception and alar screw reception capabilities, allowing simultaneous stabilization functions to be achieved through one implanted component rather than multiple separate implants, thereby reducing operating time while maintaining stability
Solution Approach 2:
The sacral plate is designed with multi-functionality to perform various stabilization tasks. It can accommodate different types of fasteners (midline screws and alar screws) through specifically oriented cavities, making it a universal solution for various sacral fixation needs without requiring multiple specialized implants
2Reliability
If multiple separate implants are used for sacral fixation, then comprehensive stabilization is achieved, but device complexity and procedural steps increase
Solution Approach 1:
The patent merges the functions of multiple separate sacral fixation implants into a single integrated sacral plate. This plate contains multiple cavities oriented at different angles to receive both midline and alar fasteners, consolidating what would traditionally require separate implants into one unified device
Solution Approach 2:
While integrating multiple functions, the plate employs segmentation through its cavity design. Each cavity is specifically oriented and shaped to receive particular types of fasteners, creating segmented functional zones within the single plate structure that accommodate different fixation requirements
3Reliability
If traditional implantation methods are used, then adequate fixation is achieved, but implant backout risk remains
Solution Approach 1:
The plate design incorporates preliminary anti-action through its cavity geometry and fastener interface features. The cavities are shaped to prevent backout of fasteners through mechanical interlocking features, and the plate itself includes elements that prevent migration or displacement before actual use occurs

AI summary
A spinal implant for use with a surgical treatment comprises a plate including a surface that defines a first cavity and a second cavity. The first cavity is oriented to implant a multi-axial fastener with a sacrum. The second cavity is oriented to implant a fastener with an ala of a sacrum. Systems and methods of use are disclosed.
