ABSTRACT

ObjectivesTo investigate correlation between slip percentage (SP) of spondylolisthesis and cross-sectional area (CSA) of lumbar paraspinal muscles; psoas major (PM), multifidus (MU) and erector spinae (ES).MethodsA retrospective study was carried out in 120 spondylolisthesis patients who had visited the Spine center of Kyung Hee University Hospital at Gangdong and had taken lumbar MRI. CSA of lumbar paraspinal muscles was measured from axial T2-weighted MRI and divided by CSA of vertebral body to avoid weight’s influence. SP was also measured from sagittal MRI.ResultsSP increase has significant correlation with decreased CSA-MU (r=0.37, p<0.01) and increased CSA-ES (r=0.19, p<0.05). There was no significant correlation be-tween SP and CSA-PM.ConclusionsMU atrophy and ES hypertrophy have significant correlation with SP of spondylolisthesis. CSA of lumbar paraspinal muscles can be a risk factor of progression of spondylolisthesis and compensation for the instability. (J Korean Med Rehab 2016;26(1):95-102)
