According To The ROC Curve Analysis Of SLIC Score,the Surgical Approach Of Lower Cervical Spine Injury Was Established For Clinical Research

Objective:To explore the significance of different SLIC score levels in guiding the choice of surgical access in patients with lower cervical spine injury by ROC analysis curves.Methods:A retrospective analysis was conducted on patients with lower cervical spine injury From September 2017 to September 2021,he entered the First Affiliated Hospital of North High School.All the patients were operated on in the hospital.,and the effectiveness of surgical treatment was verified: the recovery of patients’ neurological function after surgery was evaluated by using the ASIA grading and JOA grading standards,and the bone graft fusion was evaluated by the Bridgell bone graft fusion grading.All patients were given SLIC score before operation.The ROC curve was drawn according to the SLIC score level and the surgical approach.According to the cut-off value and AUC obtained from the curve results,the guiding significance of different SLIC score levels in the selection of surgical methods for patients with lower cervical spine injury was analyzed.Results:The patients were followed up regularly for 0.33 to 3.78 years,2.35 years on average.Symptoms such as pain and anesthesia were different during the last visit.Follow-up x-ray film or CT three-dimensional reconstruction or MRI plain scan showed that the cervical spine sequence recovered well and showed bony fusion.ASIA grade: the average ASIA grade of patients after operation was increased by 1.16,significantly higher than that before operation(P<0.05);JOA score: compared with preoperative,the JOA score of postoperative patients was significantly improved(P<0.05);Bridgell bone graft fusion grade: 37 patients of grade I,12 patients of grade II.The overall bone graft fusion condition was satisfactory,and the surgical effectiveness of all patients has been verified.The ROC curve was drawn according to the SLIC score level and the surgical approach,and the SLIC score critical point of the combined surgical approach and the simple surgical approach was calculated according to the Youden index.The SLIC score critical point of the combined surgical approach was7.5,and the SLIC score critical point of the simple surgical approach was 6.5.The scoring results are all taken an integer,which shows that when SLIC score ≥ 8 points,it was more likely to perform anterior and posterior combined surgery;When SLIC score=7 points,it was inclined to perform posterior surgery,and when SLIC score was less than 7points,it was more inclined to perform anterior surgery.By comparing the AUC of anterior and posterior combined surgical approach with that of simple surgical approach,P was 0.021,the difference was statistically significant,and SLIC score guided the prediction accuracy of anterior and posterior combined surgery.Conclusion:1.Clinicians can decide whether to take surgical treatment or not according to the SLIC score,and can also make surgical approach according to the SLIC score.2.If the SLIC score is between 8 and 10,the lower cervical spine injuries are serious,and combined approach surgery is often needed.
