Abstract
To investigate the application effect of tilt-angle low-dose ComputedTomography (CT) scanning guidance technology in the plasma radiofrequency treatment of lumbar 5-sacrum 1 (L5-S1) intervertebral disc herniation. A total of 43 patients with L5-S1 disc herniation were included in this study and categorized into vertical-angle-guided CT (Group A, n = 21) and tilt-angle-guided CT (Group B, n = 22) groups. Percutaneous plasma L5-S1 disc radiofrequency treatment was administered. The total number of punctures and scans, operation times, and Numerical Rating Scale (NRS) pain scores (preprocedure and 3 and 30 days postprocedure) were documented. Compared with Group A, punctures and scans were fewer in Group B, and the differences were statistically significant (P = 0.0001). Moreover, the CT scan-guided total surgery time was significantly shorter in Group B than in Group A (P = 0.0001). In addition, the NRS score exhibited a statistically significant difference among preprocedure (T0), 3 day postprocedure (T1), and 30 days (T2) in Groups A (P < 0.05). The NRS score exhibited a statistically significant difference between T0 and T1 and between T0 and T2 in Group B (P < 0.05), but not between T1 and T2 in Group B (P = 0.084). At three time points (T0, T1, T2), there was no statistically significant difference between the two groups (P > 0.05). The tilt-angle low-dose CT scanning technique for L5-S1 disc herniation offers the advantages of high efficiency, low damage, and low radiation, and its clinical application is recommended.
