Patient-Specific Osteosynthesis Plate Modeling From 3D Bone Anatomy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical practices often use a one-size-fits-all approach for osteosynthesis plates, which do not account for the unique anatomical variations among patients, leading to imprecise and time-consuming surgical procedures and increased operational burdens in healthcare facilities.
Innovation Solution
A method for generating customized osteosynthesis plates using 3D bone models, where virtual entry points and surfaces are determined to create a personalized osteosynthesis plate model, which is then manufactured using additive or subtractive manufacturing techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If customized osteosynthesis plates are produced for each patient, then surgical precision and adaptability are improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent applies preliminary action by generating the customized osteosynthesis plate model before the surgical procedure. The digital model is created in advance using patient-specific imaging data, allowing surgeons to plan the procedure with precision without facing complexity during surgery. The virtual planning phase includes defining entry points, trajectories, and plate positioning beforehand.
Solution Approach 2:
The patent uses copying by creating a digital replica of the patient's bone anatomy from imaging data (CT or MRI scans). This digital bone model serves as a copy that can be manipulated virtually to design the customized plate, avoiding the need to work directly with the patient's anatomy during manufacturing or surgery.
2Manufacturing precision
If customized osteosynthesis plates are manufactured for each patient, then surgical precision is improved, but production time and operational burden increase
Solution Approach 1:
The patent replaces mechanical manufacturing processes with automated digital workflows. Instead of manual plate design and adjustment, the system uses software to automatically generate the customized plate model based on imaging data. Virtual reality and computer-aided design tools substitute for traditional mechanical planning methods, reducing both production time and operational burden.
Solution Approach 2:
The patent applies parameter changes by allowing flexible adjustment of plate geometry, thickness, hole positions, and material properties in the digital model. These parameters can be modified based on specific patient anatomy and surgical requirements, enabling high precision without requiring complete redesign from scratch for each case.
3Reliability
If virtual planning and customization are implemented, then surgical outcomes are improved, but technological complexity and equipment requirements increase
Solution Approach 1:
The patent applies universality by designing a multi-functional integrated system that combines imaging data processing, 3D bone model generation, virtual plate design, and manufacturing guidance into a single platform. This universal system can handle various bone types, fracture patterns, and plate configurations, improving surgical reliability without requiring multiple separate complex systems.

AI summary
Method for generating an osteosynthesis plate comprising obtaining a bone model representing a bone and generated from imaging data corresponding to the bone, determining a set of virtual input locations in the bone model, and constructing a virtual surface adjacent to the bone model on the basis of the bone model and of all of the virtual input locations.
