Rotatable Bone Plate With Integrated Rod For Cervical Spine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bone fixation systems for spinal procedures lack flexibility and customization, particularly in the cervical spine area due to the small size of vertebrae and proximity to spinal nerves, which complicates stabilization and fusion procedures.
Innovation Solution
A hybrid bone fixation system featuring a bone plate with an integrated rod portion and aperture configuration that allows for flexible positioning and locking, enabling greater surgeon control over compression and distraction, and stabilization of bony structures through a hybrid attachment mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional single-material bone plates are used, then structural strength and stability are maintained, but flexibility and customization capability during implantation are limited
Solution Approach 1:
The patent combines a bone plate with an integrated rod portion into a single hybrid fixation device. The bone plate body and rod portion are formed as one integrated structure, allowing the device to function both as a plate for vertebral body attachment and as a rod for posterior element stabilization, thereby increasing adaptability without requiring multiple separate components
Solution Approach 2:
The hybrid fixation device is designed to perform multiple functions: the bone plate portion can be attached to vertebral bodies while the integrated rod portion can be attached to posterior elements such as laminae or spinous processes. This multi-functional design allows a single device to provide both anterior and posterior stabilization, enhancing versatility during spinal fusion procedures
2Ease of operation
If bone plates are made with integrated rod portions for hybrid fixation, then surgeon control over compression and distraction is improved, but the device profile and size increase
Solution Approach 1:
The hybrid fixation device incorporates dynamic adjustment capabilities through the integrated rod portion, which can be positioned and secured at various angles and orientations. The rod portion can be attached to the bone plate at different positions along its length, allowing the surgeon to adjust the degree of compression or distraction applied to the vertebral bodies during implantation
3Reliability
If fixation systems are designed for cervical spine applications, then stabilization of small vertebrae is achieved, but the available space for device placement and nerve proximity complicate the procedure
Solution Approach 1:
The hybrid fixation device is segmented into distinct functional portions: the bone plate body for attachment to vertebral bodies and the integrated rod portion for attachment to posterior elements. This segmentation allows each portion to be optimized for its specific function while maintaining a compact overall structure suitable for cervical spine applications where space is limited

AI summary
The present invention relates generally to a bone plate for stabilizing bony structures. More particularly, the invention is directed to bone plates having an elongate body to which an integrated rod is formed. Integrated rod portion may be captured by a bone anchor with a receiving member. The bone plate is movable from a first position to a second position and may have an aperture for lagging the bone plate to the bone.
