3D打印辅助导板在青少年脊柱侧弯手术中的应用
Application of 3D-printed auxiliary guides in adolescent scoliosis surgery
摘要
Abstract
Objective To investigate the accuracy and safety of pedicle screw placement using 3D-printed auxiliary guides in scoliosis correction surgery for adolescents.Methods A retrospective analysis was conducted on the clinical data of 51 pa-tients who underwent posterior scoliosis correction surgery from January 2020 to March 2023.Among them,there were 35 cases of adolescent idiopathic scoliosis and 16 cases of congenital scoliosis.The patients were divided into two groups based on the auxiliary tool used:the 3D-printed auxiliary guide screw placement group(3D printing group)and the free-hand screw place-ment group(free-hand group,without auxiliary tools).The 3D printing group included 32 patients(12 males and 20 females)with an average age of(12.59±2.60)years;the free-hand group included 19 patients(7 malesand 12 females)with an average age of(14.58±3.53)years.The two groups were compared in terms of screw placement accuracy and safety,spinal correction rate,intraoperative blood loss,number of intraoperative fluoroscopies,operation time,hospital stay,and preoperative and last follow-up scores of the Scoliosis Research Society-22(SRS-22)questionnaire.Results A total of 707 pedicle screws were placed in the two groups,with 441 screws in the 3D printing group and 266 screws in the free-hand group.All patients in both groups successfully completed the surgery.There was a statistically significant difference in operation time between the two groups(P＜0.05).The screw placement accuracy rate of the 3D printing group was 95.46％(421/441),among which the Grade A placement rate was 89.34％(394/441);the screw placement accuracy rate of the free-hand group was 86.47％(230/266),with a Grade A placement rate of 73.31％(195/266).There were statistically significant differences in the accuracy of Grade A,B,and C screw placements between the two groups(P＜0.05),while no statistically significant differences were ob-served in intraoperative blood loss,number of fluoroscopies,correction rate,or hospital stay(P＞0.05).In the SRS-22 ques-tionnaire scores,the scores of functional status and activity ability,self-image,mental status,and pain of patients in each group at the last follow-up were significantly improved compared with those before surgery(P＜0.05),but there were no statistically significant differences in all scores between the two groups(P＞0.05).Conclusion In scoliosis correction surgery,compared with traditional free-hand screw placement,the use of 3D-printed auxiliary guides for screw placement significantly improves the accuracy and safety of screw placement and shortens the operation time.关键词
