| 【摘要】 目的：比较3D打印个体化导板与机器人辅助置钉在成人退变性脊柱侧凸（adult degenerative scoliosis，ADS）矫形手术中的应用效果。方法：对2020年1月~2022 年12月在本科室住院接受矫形手术治疗的18例ADS患者进行回顾性分析，其中男性3例，女性15例，年龄46~73岁，平均63.2±8.2岁。共置入椎弓根螺钉236枚，根据辅助置钉方式分为两组，3D打印个体化导板组（3D打印组，11例，置入142枚椎弓根螺钉）和机器人辅助组（机器人组，7例，置入94枚椎弓根螺钉）。术后均进行至少6个月随访。术前测量并比较顶椎旋转角、侧凸Cobb角；术后1周采用Gertzbein-Robbins分类标准对所有椎弓根螺钉进行判断分类，对比两组患者螺钉置入的准确性和满意度；分析比较两组患者的手术时间和并发症发生率。结果：3D打印组年龄（63.6±9.0岁）、性别（男/女：2/9）、平均置钉数量（12.91±3.83枚）、侧凸Cobb角（40.36°±11.82°）、顶椎旋转角（30.27°±7.25°）分别与机器人组[年龄（62.6±7.3岁）、性别（男/女：1/6）、平均置钉数量（13.43±3.60枚）、侧凸Cobb角（38.14°±12.84°）、顶椎旋转角（29.86°±9.65°）]比较，均无统计学意义（P>0.05）。机器人组较3D打印组手术时间长（354.29±53.73min vs. 282.27±73.87min），差异有统计学意义（P<0.05）。置钉结果统计，3D打印组共置入142枚椎弓根螺钉，其中A类128枚，B类10枚，C类4枚；机器人组共置入椎弓根螺钉94枚，其中A类86枚，B类5枚，C类3枚；两组患者均未出现D、E两类；3D打印组置钉准确率（90.14%）及满意度（97.18%），分别与机器人组置钉准确率（91.49%）及满意度（96.81%）比较均无统计学差异（P>0.05）。并发症发生率，3D打印组（36.36%）与机器人组（57.14%）比较无显著差异（P>0.05）。结论：两种辅助置钉方式均可以协助脊柱外科医师进行ADS患者的精准置钉，但3D打印个体化导板置钉用时更短。 |

| 【Abstract】 Objectives: To compare the effects of 3D-printed personalized guiding template and robot-assisted pedicle screw placements in orthopedic surgery for adult degenerative scoliosis(ADS). Methods: Retrospective analysis was conducted on 18 ADS patients hospitalized and treated with corrective surgery in the department between January 2020 and December 2022. There were 3 males and 15 females, aged 46-73(63.2±8.2) years old. A total of 236 pedicle screws were placed, and the patients were divided into two groups according to the auxiliary screw placement methods: the 3D-printed personalized guiding template group(3D-printed group, 11 cases, 142 pedicle screws were placed) and robot-assisted screw placement group (Robot group, 7 cases, 94 pedicle screws were placed). The patients were followed up for 6 months and more. The vertex rotation angle and scoliosis Cobb angle were measured and compared between groups before operation. All pedicle screws were classified by Gertzbein-Robbins classification standard at 1 week after operation, and the accuracy and satisfaction of screw placement in the two groups were compared; And the operative time and incidence of complications were also analyzed and compared between the two groups. Results: The 3D-printed group was not statistically different from the robot group in terms of age(63.6±9.0 years vs. 62.6±7.3 years), gender ratio(male/female: 2/9 vs. 1/6), number of screws placed(12.91±3.83 vs. 13.43±3.60), Cobb angle(40.36°±11.82° vs. 38.14°±12.84°), and vertex rotation angle(30.27°±7.25° vs. 29.86°±9.65°), respectively(P>0.05). The robot group was longer in operative time than that of 3D-printed group(354.29±53.73min vs. 282.27±73.87min, P<0.05). Of the total 142 pedicle screws placed in the 3D-printed group, 128 screws were of class A, 10 were of class B, and 4 were of class C; Of the total 94 pedicle screws placed in the robot group, 86 screws were of class A, 5 were of class B, and 3 were of class C; No class D or E screws in the two groups. The accuracy rate of screw placement(90.14%) and satisfaction rate(97.18%) of the 3D-printed group were not statistically different from the accuracy rate(91.49%) and satisfaction rate(96.81%) of the robot group, respectively(P>0.05). The incidence of complications in the 3D-printed group(36.36%) was not significantly different from that in the robot group(57.14%, P>0.05). Conclusions: Both auxiliary screw placement methods can assist spinal surgeons to accurately place screws in ADS patients, but 3D-printed personalized guiding template needs less time in screw placement. |
