The initial JOA score in nonsurgical patients was significantly superior to surgical patients (t-test : p < 0.001), whereas the final JOA score and the rate of improvement were not significantly different between the two groups of patients (t-test : p > 0.05). 88.46% of nonsurgical patients and 90.00% of surgical patients had a good or excellent outcome (chi-square test : p > 0.05). However, if the 16 recurrent cases were included, the proportions dropped to 75.82% and 84.90% for nonsurgical and surgical patients, respectively. Compared with nonsurgical patients, quantitative parameters, such as midsagittal diameter and available diameter of spinal canal, lateral recess width and cross-sectional areas of spinal canal and dural sac, were significantly smaller in surgical patients (t-test : p < 0.001), and was reflected in the initial JOA score (128 cases ; Spearman rank correlation coefficient : r 0.01 = 0.486, 0.499, 0.493, 0.507, 0.484 ; p < 0.001). The spinal canal and dural sac dimensions were important predictive factors for treatment selection of lumbar disc herniation.
