主　　题：3D printing Hip revision Complex and large acetabular bone defect Accurate reconstruction 

摘      要：Complicated and large acetabular bone defects present the main challenges and difficulty in the revision of total hip arthroplasty(THA).This study aimed to explore the advantages of three-dimensional(3D)printing technology in the reconstruction of such acetabular bone *** retrospectively analyzed the prognosis of four severe bone defects around the acetabulum in three patients who were treated using 3D printing *** of bone defect by conventional methods was difficult in these *** this endeavor,we used radiographic methods,related computer software such as Materialise s interactive medical image control system and Siemens NX software,and actual surgical experience to estimate defect volume,prosthesis stability,and installation accuracy,***,a Harris hip score was obtained to evaluate limb *** was found that bone defects could be adequately reconstructed using a 3D printing prosthesis,and its stability was *** Harris hip score indicated a very good functional recovery in all three *** conclusion,3D printing technology had a good therapeutic effect on both complex and large bone defects in the revision of *** was able to achieve good curative effects in patients with large bone defects.
