Extra-Articular Distal Humerus Plate 3D Model Creation by Using the Method of Anatomical Features

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering
• Medical Device Design

Background:

• Distal humerus fractures require precise fixation for optimal outcomes.
• Current plate bending methods can be challenging, increasing surgery time and risk.
• Locking Compression Plates (LCPs) offer angular stability but may need customization.

Purpose of the Study:

• To develop an accurate pre-operative method for customizing orthopedic plates.
• To improve the geometrical accuracy of plate fixation for distal humerus fractures.
• To reduce surgical complications and enhance patient recovery.

Main Methods:

• Introduction of the Method of Anatomical Features (MAF) and Characteristic Product Features (CPF).
• Development of a parametric model for the plate-humerus contact surface using RGEs, CGEs, and ROIs.
• Customization of standard plate models to precisely fit patient-specific humerus anatomy pre-operatively.

Main Results:

• The MAF enables precise, anatomically tailored plate customization.
• Improved geometrical accuracy in plate fixation is achieved.
• Potential for pre-operative fabrication of patient-specific implants.

Conclusions:

• The MAF approach enhances the accuracy of orthopedic plate fixation.
• This method optimizes surgical outcomes and patient recovery for distal humerus fractures.
• It offers a solution to the challenges of manual plate bending.
