- Abstract: Objective To explore and analyze the role of 3D printing technology in the treatment of severe scoliosis by osteotomy combined with internal fixation. Methods A total of 42 patients with severe scoliosis who were admitted between September 2017 and September 2019 were enrolled in the study. All patients were treated with osteotomy combined with internal fixation. According to whether 3D printing technology was used to assist treatment, 21 patients receiving auxiliary treatment by 3D printing technology were divided into observation group, and the other patients were taken as control group. The perioperative indicators, number of placed nails, accuracy of nail placement and treatment effect of two groups were recorded, and the incidence of complications after treatment was also analyzed. Results [①] The perioperative indicators such as operation time, intraoperative blood loss, number of intraoperative X-ray exposure times and postoperative drainage in observation group were (115.32±15.28) min, (197.52±23.87) mL, 5.24±1.62 and (189.56±19.97) mL, respectively, better than those in control group (P<0.05). [②] A total of 106 nails were placed in observation group, and 101 nails were accurately placed, with a nail placement accuracy of 95.28%. Only 92 out of 113 nails placed in control group were placed accurately, and the nail placement accuracy was 81.42%. There was significant difference in nail placement accuracy between two groups (P<0.05). [③] After treatment, the scoliosis and kyphosis Cobb angle of two groups were significantly improved (P<0.05), and the angles in observation group after surgery and in reexamination were better than those in control group, with statistical differences (P<0.05). [④] One case of wound bleeding occurred in observation group, and the?omplication?ate was 4.76%. In control group, there were 1 case of internal fixation loosening, 2 cases of nerve injury, 2 cases of wound bleeding, and 1 case of crankshaft, with a?omplication?ate of 28.57%. The observation group had a low incidence of complications than control group (P<0.05). Conclusion Using 3D printing therapy to assist the treatment of severe scoliosis by osteotomy combined with internal fixation can effectively improve perioperative indicators, increase the accuracy of nail placement, stable the treatment effect, and reduce the incidence of complications.
