The invention discloses a method and a device for determining an
acetabular bone defect treatment mode. The method comprises the following steps: acquiring image data of
acetabular bone part of a target object; converting image data into three-dimensional data; determining the
acetabular bone defect degree of the target object according to the three-dimensional data. The target
processing strategycorresponding to the acetabular
bone defect degree of the target object is determined by a matching model, wherein, the matching model is obtained by
machine learning training using a plurality of groups of data, and each group of data in the plurality of groups includes: a
processing strategy corresponding to the acetabular
bone defect degree and the acetabular
bone defect degree. According to the target
treatment strategy, the treatment of acetabular bone defect of the target object was determined. The invention solves the technical problems that the acetabular bone loss operation is mainlyperformed according to the subjective experience and the reliability is low in the related art.
