The predominant anatomical location of lumbar disc herniation in cases of sciatic scoliosis was found to be the L4-L5 level, accounting for 56.67% (34 out of 60). The observed lumbosacral curve exhibited a typical pattern with a mean Cobb angle of 14° (range: 2.5–35, standard deviation = 7.46). The mean C7PL-CSVL distance was also measured at 36.2 mm (range: 1–170, standard deviation = 32.5). The mean lumbar lordosis was 21° (range: −1.8–50, standard deviation = 12.96), while the mean Sagittal vertical axis was recorded at 40.9 mm (range: −85–160, standard deviation = 47.8). Notably, no statistically significant difference was observed in the anatomical location of lumbar disc herniation and the apical curve level of sciatic scoliosis.
