Porous Bone Wedge Plate for Stable Osteotomy Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current osteotomy procedures face challenges with bone wedges shifting or becoming dislodged during compression, requiring multiple devices that increase complexity and cost, and existing methods do not effectively promote osteosynthesis.
Innovation Solution
A single construct bone plate segment and bone wedge segment device with a porous architecture that encourages bone growth into and around the osteotomy site, reducing the need for separate components and enhancing osteosynthesis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate devices (bone wedge and plate) are used for osteotomy, then the bone wedge can be inserted and temporarily fixed, but the bone wedge may shift or become dislodged during compression and the procedure complexity increases
Solution Approach 1:
The patent combines the bone wedge and plate into a single integrated device where the plate portion and wedge portion form one construct. This merging eliminates the interface between separate components, preventing relative movement and dislodgement during compression, while reducing the total number of devices needed for the procedure.
2Reliability
If multiple separate products are used for osteotomy, then bone fixation can be achieved, but the cost and complexity of the procedure increase
Solution Approach 1:
The integrated plate-wedge device consolidates multiple functions into one product, maintaining effective bone fixation capability while reducing the number of separate products required. This single construct provides both the wedge for osteotomy and the plate for stabilization, eliminating the need for multiple distinct products.
Solution Approach 2:
The single device performs multiple functions: the wedge portion creates and fills the osteotomy gap, while the plate portion provides fixation and stabilization. This multi-functionality allows one device to replace what would traditionally require multiple separate products, reducing procedural complexity.
3Strength
If a solid bone wedge is used, then structural support is provided, but bone growth into the wedge is limited and osteosynthesis is not effectively promoted
Solution Approach 1:
The wedge portion is constructed with a porous structure that maintains structural support while creating pathways for bone ingrowth. The porous architecture allows osteoblasts to migrate into the wedge material and deposit new bone, effectively promoting osteosynthesis while retaining the mechanical support function.
Solution Approach 2:
The device combines different material properties in the wedge portion to achieve both structural support and osteoconductivity. The composite structure integrates load-bearing capabilities with bone-regenerative properties, allowing the wedge to function both mechanically and biologically.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device stabilizes the bone wedge, promotes effective osteosynthesis by allowing bone ingrowth, and simplifies the surgical procedure by integrating the plate and wedge into a single unit, thereby reducing complexity and cost.
Implementation Method 1
At least the wedge segment of the device may include a porous architecture that encourages or allows bone to grow into it and around it on both sides of the osteotomy site
