Intra-Osseous Support Structure for Balanced Bone Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical interventions for aligning misaligned bones, such as those in the foot, often require multiple bone plates to maintain alignment, which can be cumbersome and inefficient.
Innovation Solution
A bone plating system utilizing an intra-osseous support structure placed within the bone and secured by fasteners, combined with an exterior bone plate, providing a balanced fixation system that maintains bone alignment through tension and compression forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If multiple exterior bone plates are used to maintain alignment, then bone stability is improved, but device complexity and surgical burden increase
Solution Approach 1:
The intra-osseous support structure is placed inside the bone, nested within the osseous tissue, while exterior bone plates are applied on external surfaces. This nested configuration allows the internal support to work in conjunction with external plates, providing stable fixation with potentially fewer exterior plates required.
Solution Approach 2:
The invention transitions from purely exterior bone plate fixation to a three-dimensional fixation system that includes intra-osseous (internal) support structures. This adds an internal dimension to the fixation system, distributing stabilization forces through both internal and external components.
2Stability of the object's composition
If multiple exterior bone plates are used to maintain alignment, then bone stability is improved, but ease of operation deteriorates
Solution Approach 1:
The intra-osseous support structure is inserted through openings in the bone and placed within the osseous tissue, creating a nested configuration that provides stable fixation without requiring multiple exterior plates, thereby simplifying the surgical procedure.
Solution Approach 2:
The fixation system is segmented into distinct components: intra-osseous support structures placed within specific bone regions and exterior bone plates applied on external surfaces. This segmentation allows each component to perform its specific function efficiently, reducing overall surgical complexity.
3Productivity
If intra-osseous support structure is placed within bone, then fixation efficiency is improved, but surgical precision requirement increases
Solution Approach 1:
Openings are formed in the bone portions before inserting the intra-osseous support structure. This preliminary action allows for precise positioning and preparation of the bone, ensuring that the support structure can be accurately placed within the osseous tissue to achieve optimal fixation efficiency.

AI summary
An intra-osseous support structure can be used to fixate opposed portions of bone. In some examples, the intra-osseous support structure is positioned in openings formed in adjacent portions of bones. Fasteners are inserted through the bone portions to secure the intra-osseous support structure in the bones. Depending on the application, one or more external bone plates may also be applied to the bone portions. The external bone plate may be in compression while the intra-osseous support structure is in tension under load in situ.
