Abstract

The invention discloses a method and a device for determining the degree of acetabular bone defect. The method comprises the following steps: obtaining image data of acetabular part of a target object; converting image data into three-dimensional data; dividing the three-dimensional data according to a predetermined mode to obtain the divided three-dimensional data; analyzing the divided three-dimensional data and get the analysis result, and determining the degree of acetabular bone loss corresponding to the acetabular site according to the results of the analysis. The invention solves the technical problem in the related art that the accuracy of the evaluation result obtained by the evaluation method for the acetabular bone defect in the hip joint revision operation is low.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and device for determining the degree of acetabular bone defect. Background technique [0002] As patients undergoing total hip arthroplasty age and become more active, the number of hip revision surgeries continues to increase. There are many reasons for the failure of primary total hip arthroplasty and the need for hip revision surgery, including infection, wear of the polyethylene liner of the prosthesis, and habitual dislocation of the prosthesis. Periprosthetic osteolysis caused by prosthetic wear debris, which in turn leads to aseptic loosening of the prosthesis, is always the main reason for hip revision surgery. In the face of hip revision after primary hip replacement failure, the surgical strategy and surgical technique for acetabular defect repair and reconstruction are one of the challenges for orthopedic surgeons. [0003] The assessment of aceta...
