Abstract:
BACKGROUND:Recently, the effects of lumbar facet joint morphology on the onset of degenerative lumbar spondylolisthesis have been a discussion point. However, the discussion mainly concerned CT manifestations of joint angle and osteoarthritis. Studies have shown that the changes in cross-sectional area of paraspinal muscle were considered as the essential marker for the pathological diagnosis of degenerative lumbar spondylolisthesis. However, previous studies limited the accuracy of the conclusion due to smal sample size, young age, and measurement.
OBJECTIVE:To observe changes in MRI images of bilateral paraspinal muscles after degenerative lumbar spondylolisthesis.
METHODS:This study adopted the method of retrospective study, selected 80 cases of degenerative lumbar spondylolisthesis as lumbar spondylolisthesis group, and 80 healthy persons as control group. Image J software was utilized to measure cross-sectional areas of bilateral erector spinae and psoas major muscle on the L 3-5 vertebral endplate levels using T2-weighted MRI in both groups. The ratio of relevant data was calculated.
RESULTS AND CONCLUSION:Compared with the control group, the ratio of cross-sectional area of paraspinal muscle was increased on the same side and the same level in the lumbar spondylolisthesis group (P<0.05), and the mean value of cross-sectional area of bilateral psoas major muscle was decreased on the same level (P<0.05). No significant difference in the mean value of cross-sectional area of left and right erector spinae was detected on the same level (P>0.05). Results indicated that the changes in cross-sectional area of paraspinal muscle could induce degenerative lumbar spondylolisthesis, and could be considered as a diagnostic standard for degenerative lumbar spondylolisthesis.
