Abstract Objective: To investigate the effect of 3D CT reconstruction combined with 3D printing to assist internal fixation in the treatment of acetabular fractures.Methods: From May 2013 to March 2018, 88 patients with acetabulum fracture in our hospital were selected as the research objects and categorized into the control group (n=44) and the observation group (n=44) with the random number table method.The patients in the control group were treated with 3D CT reconstruction and internal fixation, while the patients in the observation group were treated with 3D CT reconstruction and 3D printing.The operative indexes, knee joint score (HSS) and postoperative complications were recorded and analyzed.Results: The operation time, fracture healing time, intraoperative blood loss, length of hospital stay, fluoroscopy irradiation times and postoperative Hss score in the observation group were significantly lower than those in the control group (P<0.05), and the excellent and good rate of Matta score in the observation group was 88.64% (39/44), which was not significantly different from 81.82% in the control group (36/44).After operation, there were 1 case of abnormal healing, 1 case of internal fixture broken and 1 case of incision infection in the observation group, 1 case of joint adhesion and 3 cases of internal fixture broken in the control group.There was no statistically significant difference between the number of complications in the observation group(3/44) and the control group (4/44) (P>0.05).Conclusion: The application of 3D CT reconstruction combined with 3D printing in acetabular fracture internal fixation can improve the quality of operation, promote the recovery of fracture site after operation, and reduce the incidence of complications.It is worth promoting in related clinical treatment.
