基于健侧三维数字解剖的桡骨头假体逆向工程研究

Abstract

Abstract:

Objective To study the reverse engineering of radial head prosthesis based on three-dimensional digital anatomy of proximal radius on uninjured side with the technique of computer aided design in order to help the clinical accurate replacement. Methods　The double elbow joints of a healthy adult was thin slice scaned by GE Speed Light 16 CT to obtain the CT dicom data , which were then imported into Mimics10.0 software for reconstruction of the 3D image of the elbow joints. Establish the mirror image of the proximal segment of the radius on the left side which was presumed unjuried. Then edit and cut it into the head and neck sections, configure the stem through measurement of the diameter and length of the neck intermedullary canal. Meanwhile, the head DXF file was imported into Geomagic studio 12 , Finally, the reverse engineering of the radial head prosthesis was finished. Results By 3D reconstruction, edit, measurement and manipulation of the CT image data of the proximal radius on uninjured side in Mimics10.0 and Geomagic studio 12 software can reversely design the individual radial head prosthesis and simulate to make it up. Conclusion Reverse engineering based on three-dimensional digital anatomy of the proximal radius on the uninjured side provides an effective method to produce an individual radial head prosthesis.
