Abstract: Objective To investigate the clinical effect of lamina replantation with mini-titanium plate and screw internal fixation in the elderly patients with intraspinal tumors. Methods The clinical data of the elderly patients who underwent intraspinal tumor resection and lamina replantation in Department of Spine Surgery of Nanjing Pukou People’s Hospital from January 2020 to February 2024 were retrospectively analyzed. The patients were divided into mini-titanium plate and screw internal fixation group(group A) and a pedicle screw internal fixation group(group B). The age, gender, operation time, blood loss, postoperative drainage volume, American Spinal Injury Association(ASIA) grade, postoperative cerebrospinal fluid leakage, spinal sagittal diameter, Visual Analogue Scale(VAS) score, Oswestry disability index(ODI) score were recorded and compared between the two groups. Results A total of 78 patients were enrolled in this study, with 42 cases in group A and 36 patients in group B. Compared with group B, the operation time and intraoperative blood loss in group A were significantly reduced(P<0.05). The VAS score and ODI score of the two groups 1 week and 1 year after surgery were significantly lower than those before surgery (P<0.05), and the VAS score and ODI score 1 year after surgery were significantly lower than those 1 week after surgery (P<0.05). Furthermore, the VAS score in group A 1 year after surgery was significantly reduced than that in group B (P<0.05). After operation, the symptoms and signs of the patients were significantly improved. The vertebral plates were fully bony healed. Conclusions For the elderly patients with spinal canal tumors, micro titanium plate and screw internal fixation has the advantages of shortening the operation time, reducing the bleeding, and reducing the long-term pain degree.
