ADVERSE EVENTS
Pain and disability scores were collected at baseline, 6-month, and 12-month follow-up evaluations. Two lumbar patients did not present for their 6-month follow-up and a total of 23 patients (11 cervical; 12 lumbar) were lost to follow-up for various reasons at the 12-month visit—none of which were reported to have any adverse events or be deceased. Additionally, 6-month pain and disability scores were unavailable for two patients (1 cervical; 1 lumbar), and five patients at 12-month follow-up (1 cervical; 4 lumbar).All patient-reported outcomes demonstrated statistically significant improvements (Pain and Disability ScoresVisual Analog Scale (VAS) Scores. VAS assessment scores presented as Median (IQR, 25th–75th percentile); Cervical baseline: 7 (5–8), 6-month: 4 (2–6), 12-month: 3 (2–6); Lumbar baseline: 7 (6–8), 6-month: 2 (1–6), 12-month: 2 (1–5). * indicates VAS change at each postoperative time point (6-month and 12-month) was significantly improved compared to the baseline score (Neck Disability Index (NDI) and Oswestry Disability Index (ODI) Scores. NDI and ODI scores presented as Median (IQR, 25th–75th percentile); Cervical NDI baseline: 60 (47–67), 6-month: 38 (16–56), 12-month: 28 (15–50); Lumbar ODI baseline: 52 (43–60), 6-month: 24 (10–48), 12-month: 16 (2–38). * indicates NDI and ODI change at each postoperative time point (6-month and 12-month) was significantly improved compared to the baseline score (Overall, there was a 51.5% improvement in VAS-pain (41.5% cervical, 60.6% lumbar), 42.6% in NDI, and 55.4% in ODI from baseline to 12 months. Comparison of subjective measures between 6- and 12-month postoperative follow-up were not statistically significant.
