Osteosynthesis Plate With Segmented Legs For Olecranon Fractures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current osteosynthesis plates for treating fractures or osteotomies near joints, particularly around the olecranon, face challenges such as soft tissue injury, inadequate stability, and post-surgical complications like skin necrosis and irritation due to their design, which restricts joint mobility and requires additional surgeries for removal.
Innovation Solution
An osteosynthesis plate with two lateral legs and a thin bridge element that avoids areas where tendons and ligaments radiate, allowing for stable fixation without covering these regions, reducing soft tissue strain and minimizing complications by being adaptable to individual anatomy and able to distribute forces effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the osteosynthesis plate covers the region where tendons and ligaments radiate into the bone, then the stability and fixation strength are improved, but the soft tissue injury and post-surgical complications increase
Solution Approach 1:
The osteosynthesis plate is divided into two separate legs (first leg and second leg) that are spaced apart from each other. This segmentation allows the plate to provide stable fixation across the fracture site while leaving the region where tendons and ligaments radiate into the bone uncovered, thereby avoiding soft tissue injury.
2Object-affected harmful factors
If the osteosynthesis plate is designed to be thin to reduce soft tissue strain, then the risk of skin necrosis and irritation is reduced, but the stability to absorb tensile and torsional forces is compromised
Solution Approach 1:
The osteosynthesis plate features a thin bridge element connecting the two legs, which reduces soft tissue strain and risk of skin necrosis. Despite the thin bridge element, the overall structure maintains sufficient stability to absorb tensile and torsional forces through the strategic positioning of the legs and the bridge element's connection to both legs.
3Ease of operation
If the osteosynthesis plate uses a simple design to reduce surgical complexity, then the ease of operation is improved, but the ability to ensure correct reconstruction and prevent complications is reduced
Solution Approach 1:
The osteosynthesis plate employs an asymmetric design where the first leg and second leg are positioned at different locations relative to the fracture site, with the bridge element connecting them in a specific configuration. This asymmetric arrangement ensures correct reconstruction of the bone while maintaining surgical simplicity, as the plate's geometry guides proper placement without requiring complex alignment procedures.

AI summary
An osteosynthesis plate according to the invention has at least two legs, which are spaced apart and interconnected by at least one bridge element. The legs each have a certain length and extend in the longitudinal direction from an epiphyseal to a diaphyseal end of the osteosynthesis plate. Moreover, each leg has at least one opening for holding an anchoring element. The size and shape of the bridge element and the legs are configured such that the legs may be applied on both sides of a bone in the region of a joint, preferably on the olecranon.
