Abstract Objective: To analyze the role of of CT data hip bone 3D model reconstruction in hip replacement. Method: A total of 80 patients with hip arthroplasty admitted to the Department of Bone and Joint Surgery of Pingxiang People's Hospital from January 2020 to January 2022 were selected and divided into two groups with 40 patients in each group by random number table method. The 2D group was evaluated by traditional 2D image before and after surgery, and the 3D group was evaluated by 3D image reconstruction of hip bone based on CT data before and after surgery. Imaging measurements (proximal femur matching degree, femoral offset, anteversion angle, abduction angle) before and after surgery, surgical indicators, excellent and good rate of postoperative hip function, and total incidence of complications were compared between the two groups. Result: Six months after surgery, anteversion angle and abduction angle of the 3D group were lower than those of the 2D group, the differences were statistically significant (P<0.05). The matching degree and femoral offset of proximal femur in the 3D group were higher than those in the 2D group, the differences were statistically significant (P<0.05). All surgical indexes in the 3D group were better than those in the 2D group, the differences were statistically significant (P<0.05). Three months after surgery, the excellent and good rate of hip joint function in 3D group (95.00%) was higher than that in 2D group (80.00%), the difference was statistically significant (P<0.05). One months after surgery, the total complication rate of the 3D group (2.50%) was lower than that of the 2D group (20.00%), the difference was statistically significant (P<0.05). Conclusion: The introduction of hip bone 3D model reconstruction technology based on CT data before and after hip replacement can effectively improve hip joint function, reduce blood loss and drainage volume, shorten operation and recovery time, reduce the incidence of complications, and improve surgical safety.
