OBJECTIVE: To study the difference of spino-pelvic sagittal alignment between lumbar disc herniation(LDH) and lumbar canal stenosis(LCS) in adults.
METHODS: The integrated imaging data of 88 patients with lumbar disc herniation (42 cases) or lumbar canal stenosis(46 cases) were searched from January 1, 2015 to September 10, 2016 in our hospital.Twenty-two cases were excluded because of age factor, 36 cases of LDH (LDH group) and 30 cases of LCS (LCS group) were internalized in the study. The spino-pelvic parameters were measured including pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), lumbar lordosis (LL), thoracic kyphosis (TK), thoracolumbar junction (TLJ), sagittal vertical axis (SVA), sagittal vertical axis location (SVA-Location), T₁-spinopelvic inclination (T₁-SPI), T9-spinopelvic inclination (T₉-SPI). Independent sample t test was used in order to analyze the above data.
RESULTS: Thoracic kyphosis (TK) in LDH group was smaller than that of LCS group (difference was about 6 degree), there was significant difference between two groups (P=0.031). And there were no significant differences in other parameters between two groups (P>0.05).
CONCLUSIONS: The patients with lumbar disc herniation, the kyphosis of the thoracic spine is smaller, the truncus prones to the straight. The lumbar kyphosis is greater in patients with lumbar spinal stenosis, and the sagittal curvature of the lumbar spine is more obvious.
