Chen 等也认为3D打印模板预实验有助于手术中准确的放置髓内针【19

Chen et al. also believe that the 3D printing template pre-experiment is helpful for accurate intramedullary needle placement during surgery [19]. <br><br>It can be concluded from the study that the experimental group is superior to the control group through 3D printing technology assisted surgery. There are statistically significant differences in operation time, blood loss, and postoperative hospital stay (operation time, blood loss, p=0.00 ; Postoperative hospital stay, p=0.03), the hip joint function score of the experimental group was significantly improved compared with the control group (p=0.03), suggesting that the integration of 3D printing technology is slightly more complicated for preoperative examination and preoperative imaging preparations. The quality of surgery is significantly improved compared to traditional surgery.

Chen et al. also believe that the pre-experiment of 3D printing templates will help to place myelin needles accurately during surgery.<br><br>It can be concluded from the study that the experimental group is superior to the control group by 3D printing technology to assist surgery, in terms of operating time, bleeding volume, postoperative hospitalization time, with statistical differences (surgery time, bleeding amount, p-0.00; post-operative hospitalization time, p- 0.03), hip function scoring experimental group than the control group improved significantly (p -0.03), suggesting that the integration of 3D printing technology although preoperative examination and preoperative imaging preparation is slightly more complex, but the quality of surgery than traditional surgical methods significantly improved.
