Acquisition method of prediction index for predicting press-fit stability of acetabular prosthesis before operation

A method for acquiring a prediction index for predicting the press-fit stability of an acetabular prosthesis before an operation comprises the following steps: step (1), defining a hip X-ray image to be predicted before the operation as an image to be detected, and sketching a region of interest in the image to be detected; (2) performing feature extraction on the region of interest in the step (1) through a feature extraction tool to obtain features to be predicted; (3) screening the to-be-predicted features in the step (2) through a machine learning algorithm to obtain screened features; and step (4), inputting the screened features into a pre-obtained optimal model for calculation to obtain a prediction index. According to the method for obtaining the prediction index for predicting the press-fit stability of the acetabular prosthesis before the operation, the prediction index for predicting the press-fit stability of the acetabular prosthesis before the operation can be obtained. 一种术前预测髋臼假体压配稳定性预测指标的获取方法,
