This study aimed to investigate the impact of three-dimensional (3D)-printed guide plate-assisted percutaneous pedicle screw implantation on minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) surgery.
Overall, 162 patients who underwent MIS-TLIF at Tai'an City Central Hospital were retrospectively reviewed. The studied variables included operative time, volume of intraoperative blood loss, fluoroscopy time, postoperative drainage volume, visual analogue scale (VAS) score, Oswestry disability Index (ODI) score (preoperatively and at 2 weeks, 3 months, 6 months, and 12 months after surgery), and intervertebral fusion rate at 6 months after surgery.
The conventional group included 99 patients who underwent a conventional procedure, while the 3D printing group included 63 patients who underwent 3D-printed guide plate-assisted percutaneous pedicle screw implantation. The conventional group required more times of positioning needle punctures than the 3D printing group (22.2 ± 5.9 vs. 16.1 ± 4.9). The operation and fluoroscopy time were also longer in the former group (183.5 ± 51.1 min vs. 148.8 ± 40.3 min and 30.2 ± 5.9 s vs. 24.1 ± 4.9 s, respectively). In 3D printing group, lower back pain VAS scores and ODI scores at 2 weeks and 3 months after surgery were observed. There were no significant differences in terms of the volumes of intraoperative blood loss; postoperative lower limb pain VAS scores; and interbody fusion rate (P > 0.05).
The novel 3D-printed guide plate-assisted percutaneous pedicle screw implantation can achieve better amelioration of back pain and recovery of function. It also reduced the times of positioning needle puncture and fluoroscopy time during percutaneous screw placement surgery and reduced the duration of surgery.
本研究旨在探讨三维（3D）打印导板辅助经皮椎弓根螺钉植入对微创经椎间孔腰椎间融合术（MIS-TLIF）的影响。
回顾性分析泰安市中心医院 162 例接受 MIS-TLIF 的患者。研究变量包括手术时间、术中出血量、透视时间、术后引流量、视觉模拟评分（VAS）、Oswestry 功能障碍指数（ODI）评分（术前及术后 2 周、3 个月、6 个月和 12 个月）和术后 6 个月椎间融合率。
常规组 99 例行常规手术，3D 打印组 63 例行 3D 打印导板辅助经皮椎弓根螺钉植入术。常规组定位针穿刺次数多于 3D 打印组（22.2±5.9 次比 16.1±4.9 次）。前者的手术和透视时间也更长（183.5±51.1 min 比 148.8±40.3 min 和 30.2±5.9 s 比 24.1±4.9 s）。3D 打印组术后 2 周和 3 个月腰痛 VAS 评分和 ODI 评分较低。术中出血量、术后下肢疼痛 VAS 评分和椎间融合率无差异（P>0.05）。
新型 3D 打印导板辅助经皮椎弓根螺钉植入术可更好地改善腰痛和功能恢复，减少经皮螺钉置入术中定位针穿刺次数和透视时间，缩短手术时间。
