[Retracted] Application of Digital Orthopedic Technology in Orthopedic Trauma

Comparison of modeling methods.
Grinding method
CT tomography method
Advantages: accurate information of model section geometry and accurate distribution of bone trabecula can be obtained
Advantages: (1) the section geometry is accurate, and it can be quickly and accurately digitized, reducing the error; (2) the integrity of the model is not damaged; (3) the nonuniformity of the section of bone tissue material can be reflected
Disadvantages: (1) the model is destroyed and bone tissue is lost due to cutting; (2) it is difficult to obtain a consistent thickness of the section when the section is very thin; (3) sufficient time is required to prepare the model, and the section geometry is digitized with large error
Disadvantages of nonuniformity of material cross-section: (1) it is difficult to determine the alignment direction of bone trabecula; (2) CT scanning requires multiple channels
