Distal Radius Bone Plate for Anatomical Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for improved plating systems that provide anatomical articular reduction and stable fixation of the radius, particularly in the case of radial fractures, as existing methods often result in low stress concentration and inadequate stabilization.
Innovation Solution
The stabilization system includes a bone plate with various types of fasteners, such as locking, non-locking, and polyaxial fasteners, designed to secure to the radius or ulna, featuring specialized holes and configurations that allow for dynamic compression and precise placement, reducing stress concentration and enhancing stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plate is used to fixate the fractured bone with screws, then the bone is reinforced during healing, but the stress concentration in the bone remains relatively low due to large contact area
Solution Approach 1:
The plate design incorporates localized stress concentration features at specific regions of the plate-bone interface, creating areas of heightened stress that promote fracture healing through controlled mechanical stimulation, while maintaining overall stability through the distributed screw fixation system
2Reliability
If locking screws are used to secure the plate, then the fixation stability is improved, but the device complexity increases
Solution Approach 1:
The fixation system is divided into modular components with distinct functions: locking screws for angular stability, non-locking screws for compression, and specialized plate regions for different fixation needs. This segmentation allows each component to be optimized independently while maintaining overall system simplicity through standardized interfaces
3Reliability
If the plate is designed for anatomical articular reduction, then the fracture healing is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The plate is pre-contoured with anatomical shaping that matches the radial bone surface geometry, allowing for preliminary alignment and reduction before final screw fixation. This pre-formed anatomical configuration reduces the precision requirements during surgical implantation while maintaining the benefits of anatomical reduction for fracture healing

AI summary
Devices, systems, and methods for bone stabilization, especially ulna head stabilization. The stabilization system may include a bone plate having an elongated portion extending along a longitudinal axis between a proximal end and a distal end. The bone plate defines a plurality of through holes extending through the elongated portion. A plurality of fasteners are configured to extend through one or more of the plurality of through holes in the bone plate and configured to secure the bone plate to the bone. The proximal end of the elongate portion has an arcuate configuration.
