Abstract

The invention discloses a total hip replacement preoperative planning method and device based on deep learning and X rays. The method comprises the steps of obtaining an X-ray image of the hip joint,wherein the X-ray image of the hip joint comprises an image of a reference object, and the reference object is a reference object with the known size; restoring the size of the X-ray image of the hipjoint according to the image size of the reference object and the proportion of the actual size of the reference object; identifying the restored X-ray image of the hip joint based on a deep learningmodel, and determining a leg length difference, an acetabular cup position and a specification model of a femoral stem prosthesis; and determining the position of an osteotomy line according to a rotation center of the femoral stem prosthesis and a rotation center of the acetabular cup determined in the X-ray image identifying process of the hip joint. The invention aims to provide a more convenient and accurate preoperative planning mode for providing better preoperative support for a total hip replacement surgery.

Description

technical field [0001] The present application relates to the field of medical technology, in particular, to a preoperative planning method and device for total hip replacement based on deep learning and X-rays. Background technique [0002] In the medical field, the preoperative planning of total hip replacement surgery mainly includes the calculation of the required prosthesis type and the position of the osteotomy line. The preoperative planning of total hip joint replacement surgery plays a very important role in the success rate of the operation. Therefore, how to It is very important to provide accurate preoperative planning. At present, the main method of preoperative planning is manual measurement through various tools, which is inefficient and cannot guarantee accuracy. Therefore, it is urgent to provide a more convenient and accurate preoperative planning method to provide better results for total hip replacement surgery. Preoperative support.
