| description | Jialuo Han, Jianwei Guo, Xuexiao Ma, Guoqing Zhang, Shuo Han, Hao Zhang, Houchen Liu, Mingrui Chen, Yan Wang Department of Spinal Surgery, the Affiliated Hospital of Qingdao University, Shandong, People’s Republic of ChinaCorrespondence: Yan Wang, Department of Spinal Surgery, the Affiliated Hospital of Qingdao University, No. 59 Haier Road, Qingdao, Shandong, 266000, People’s Republic of China, Tel +86 17853297089, Email sanwang1986@163.comPurpose: The objective of this study was to describe the Mazor Renaissance robotic system-assisted CBT (cortical bone trajectory) screw technique as a salvage strategy for failed lumbar spine surgery.Patients and Methods: Between January 2018 and June 2022, 7 patients underwent salvage surgery with the CBT screw fixation technique assisted by the Mazor Renaissance robot system in our institution. Intraoperative observations were recorded for blood loss, duration of operation, and fluoroscopy time. Complications related to CBT screws were also recorded. The accuracy of CBT screws was recorded in accordance with the modified Gertzbein-Robbins classification. The JOA (Japanese Orthopedic Association) score for low back pain was used to evaluate surgical outcomes.Results: A total of 26 CBT screws were placed in 7 patients, including 4 females and 3 males. Three patients underwent ASD (adjacent segment disease) and four patients underwent lumbar union failure with loose or compromised PSs (pedicle screws). The mean operation time was 129.29 ± 32.97 minutes, the mean blood loss was 180 ± 52.60 mL, and the mean intraoperative fluoroscopy time was 14.29 ± 3.15 s. All screws were clinically acceptable according to the Gertzbein-Robbins classification. There were no complications related to CBT screws in any of the cases. The JOA scores for low back pain of all patients were significantly improved at the final follow-up.Conclusion: The CBT screw fixation technique supplemented the traditional PS fixation technique, which can be performed as a salvage strategy for failed lumbar spine surgery and achieved good clinical results. The spinal robot was very helpful in evaluating pedicle size and determining CBT screw direction, especially in a previously instrumented lumbar pedicle.Keywords: CBT screw, robot-assisted, salvage strategy, ASD |
