Wedge-Shaped Bone Re-alignment Device for Osteotomy Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current osteotomy procedures for correcting bone misalignment in orthopedic surgery are often complex and lack precision, requiring significant surgical intervention and potential for uneven weight distribution across joints.
Innovation Solution
A system comprising a wedge-shaped body with fixation members, such as screws or staples, designed to re-align bones by securing the body to the bone region, allowing for precise correction of bone angles during osteotomy procedures, including the use of intramedullary posts and total joint replacement stems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional osteotomy procedures are used to correct bone misalignment, then bone realignment can be achieved, but the procedure is complex and lacks precision
Solution Approach 1:
The patent applies preliminary action by pre-forming a wedge-shaped cavity in the bone before insertion. This pre-prepared cavity receives the wedge-shaped body that provides the realignment force, eliminating the need for complex intraoperative realignment maneuvers and improving precision while simplifying the surgical procedure.
Solution Approach 2:
The wedge-shaped body acts as an intermediary device inserted into the pre-formed cavity. This mediator transfers and distributes the realignment force evenly across the bone structure, providing precise angular correction without requiring complex surgical techniques or multiple intervention steps.
2Ease of operation
If bone wedge removal is performed to correct misalignment, then weight distribution can be improved, but the procedure requires significant surgical intervention
Solution Approach 1:
The patent extracts only the minimal necessary bone material to create the wedge-shaped cavity, rather than removing large bone segments. This reduces surgical intervention complexity while maintaining the ability to achieve proper weight distribution through the controlled insertion of the wedge-shaped realignment device.
Solution Approach 2:
The invention changes the physical parameters of the bone structure by inserting a wedge-shaped body with specific angular dimensions into the pre-formed cavity. This parameter change directly controls the realignment angle and weight distribution characteristics, providing reliable outcomes with simpler surgical procedures.
3Manufacturing precision
If traditional osteotomy methods are used, then bone realignment is possible, but correction precision is limited
Solution Approach 1:
The patent employs asymmetric wedge-shaped bodies with specific angular configurations that are tailored to the required correction amount. This asymmetric geometry provides precise angular control for realignment while maintaining simple device construction, eliminating the need for complex adjustable mechanisms.
Solution Approach 2:
The pre-formation of the wedge-shaped cavity at defined angles provides a precise receptacle for the realignment device. This preliminary angular preparation ensures that when the wedge-shaped body is inserted, the bone is realigned to the exact desired angle with high precision without requiring complex intraoperative adjustment mechanisms.
