Objective: Comparison of the efficacy of S8 navigation system-assisted correction versus manual correction in the treatment of adolescent congenital scoliosis (ACS). Methods: A cohort study. A retrospective analysis was conducted on the clinical and imaging data of 48 patients with congenital scoliosis who were treated at the Honghui Hospital Affiliated with Xi'an Jiaotong University between May 2021 and January 2023. Based on the auxiliary systems, the patients were divided into two groups: the S8 navigation system-assisted correction group (navigation group, n =20) and the C-arm-assisted manual correction group (manual group, n =28). The primary outcome measures were coronal balance (CB), sagittal vertical axis (SVA), lumbar lordosis (LL), pelvic incidence (PI), pelvic tilt (PT), pelvic incidence-lumbar lordosis mismatch (PI-LL), and the Scoliosis Research Society-22 (SRS-22) questionnaire. The secondary outcome measures included surgery-related conditions and postoperative complications. Results: Of the 48 patients, there were 21 males and 27 females, with a mean age of (13.3±3.0) years. There was no statistically significant differences in preoperative distance of C 7 plumb line to center sacral vertical line (C 7 PL-CSVL), SVA, LL, PI, PT, PI-LL mismatch, or SRS-22 scores between the two groups (all P >0.05). Postoperatively, the C 7 PL-CSVL and SVA in the navigation group were both better than in the manual group [(12.51±11.86) mm vs (19.64±1.33) mm, (15.72±3.64) mm vs (25.42±2.53) mm, both P <0.05]. There was no statistically significant differences in postoperative LL, PI, PT, PI-LL mismatch, or SRS-22 scores between the two groups (all P >0.05). The accuracy rates for Grade 0 and Grade 0+1 screw placements were 91.17% (93/102) and 95.09% (97/102) in the navigation group, respectively, which were higher than those in the manual group [84.45% (125/148) and 91.89% (136/148), respectively] (both P <0.05). The rates of adjacent facet joint violation in Grades A, B, and C were 88.23% (90/102), 11.76% (12/102), and 0 (0/102) in the navigation group, respectively, which were all better than those in the manual group [83.44% (121/145), 8.96% (13/145), and 7.58% (11/145)] ( P =0.015). The navigation group had shorter operative time, single screw placement time, and total screw placement time, and the distance between the screws and the cortex was closer compared to the manual group (all P <0.05). Intraoperative blood loss in the manual group was higher than that in the navigation group ( P <0.05). The average curve correction rate in the navigation group (74.68%±10.70%) was better than that in the manual group (59.60%±6.90%) ( P <0.001). The intraoperative fluoroscopy dose in the navigation group was higher than that in the manual group [(416±70) mGy vs (360±81) mGy, P =0.015]. The incision length in the navigation group was longer than that in the manual group ( P <0.05). There was no statistically significant difference in preoperative VAS pain score between the two groups ( P >0.05). The postoperative visual analogue scale scores of pain on day 3 was better in the navigation group [(2.60±0.22) vs (3.10±0.32), P <0.001], while there was no statistically significant differences at other time points between the two groups (all P >0.05). No complications occurred in either group. Conclusion: The S8 navigation system demonstrates good corrective outcomes, high screw placement accuracy, low facet joint violation, and favorable clinical results in the treatment of adolescent congenital scoliosis, making it an ideal auxiliary tool. |
