Abstract:
BACKGROUND: Establishment of individual femoral model can describe the stereochemical structure of femoral accurately,which is conductive to measuring femoral anatomic forms. This model possesses unified standard, and removing the potential confounding factors, thus, it is more suitable for biomechanical test.OBJECTIVE: To explore a method for establishing an accurate individual femoral model.METHODS: A male, healthy, volunteer was selected from General Hospital of Tianjin Medical University, and the cross section of femur was successive scanned by 16 slice CT. In accordance with Dicom 3.0 standard, the CT image was reconstructed using Mimics software to establish the space model, and UG software was used to type on the workpiece, and cimatron software was used to sort, then set the coordinate system of computer numerical control machining, clamp and correct the workpiece to produce mold toolpath, so the mold was established. The femur model made by mould was compared with the femur by the method of point cloud.RESULTS AND CONCLUSION: An individual femur model was produced. The comparison results of point cloud showed that error was in allowing range. This is an advisable method to make a femoral model, which can achieve predetermined requirement.
