Bone strength simulation calculation method and device, and storage medium

A bone strength simulation calculation method, comprising:

• obtaining three-dimensional data of a cancellous bone of a bone segment to be analyzed;
• obtaining a skeleton mechanical model according to the three-dimensional data;
• performing a feature analysis on the skeleton mechanical model to obtain skeleton strength data;
• wherein trabeculae in the cancellous bone are interwoven with each other, and joints of three or more trabeculae are trabecular nodes;
• the skeleton strength data comprises a quantity data of the trabecular nodes, and/or data of angle between trabecular bones of the trabecular nodes;
• wherein the performing a feature analysis on the skeleton mechanical model to obtain skeleton strength data, comprises:
• determining a quantity of bone trabeculae constituting each trabecular node in the skeleton mechanical model to obtain a type of each trabecular node;
• extracting a quantity data of discriminant trabecular nodes in various types of trabecular nodes;
• extracting at least one type of trabecular node as a pedestal trabecular node;
• determining angles between each bone trabeculae constituting the pedestal trabecular node successively to obtain data of angles between each pedestal trabecular node;
• performing a finite element simulation on the angles between the trabecular bones of the pedestal trabecular nodes to obtain a maximum stress of each angle type.
