Analysis of Short-and Long Term Efficacy and Prognostic Factors in the Treatment of Spinal Canal Tumors with Miniature Titanium Plate Implantation and Internal Fixation
Objective:To investigate the short-term and long-term efficacy and prognostic factors of replantation of mini-titanium plate for internal fixation of spinal canal tumors.Methods:A total of 78 patients with spinal canal tumor who were treated with micro-ti-tanium plate internal fixation were selected from 2020.1 to 2023.1 in our hospital.The basic data of the patients were recorded,followed up for 1 year,and the spinal stability and lumbar function recovery were recorded.A total of 20 patients(9 patients with ineffective re-sponse and 16 patients with long-term spinal instability)were classified as the poor prognosis group,and the remaining 58 patients were classified as the good prognosis group.The clinical conditions of the two groups were compared,and the prognostic factors were ana-lyzed by logistics regression model.Results:The average operation time of 78 patients was(182.43±17.35)min,the intraoperative blood loss was(245.24±48.35)mL,the hospital stay was(23.14±4.25)d,the total effective rate was 88.46％,and the complication rate was 6.41％.The 1-year follow-up showed that the spinal stability rate was 76.92％,SFI and JOA scores were higher than those before opera-tion(P＜0.05).Good prognosis with poor prognosis group tumor diameter,nature,preoperative muscle,tumor resection,postoperative hor-mone use contrast significant difference(P＜0.05);Tumor diameter,nature,preoperative muscle strength and postoperative hormone use were independent factors(P＜0.05).Conclusion:Replanting micro-titanium plate internal fixation for spinal canal tumors is effective,im-proves the function of lumbar spine,and the postoperative complications are controllable.However,the prognosis is affected by the tumor diameter,nature,preoperative muscle strength,and postoperative hormone use.
