[Imaging study of lumbosacral multifidus muscle fat changes in patients with lumbar disc herniation]

To compare the degeneration of lumbosacral multifidus muscle in patients with lumbar disc herniation.Magnetic Resonance Spectroscopy was performed on the multifidus muscle of 35 healthy volunteers and 35 patients with unilateral LIn healthy volunteers, the proportion of fat on the left side of the multifidus muscle was (0.169± 0.035)%, the proportion of fat removal cross-sectional area on the left side of the multifidus muscle was (0.699±0.070)%, the proportion of fat on the right side of the multifidus muscle was (0.168±0.031)%, and the proportion of fat removal cross-sectional area on the right side of the multifidus muscle was (0.712±0.056)%, there was no significant difference between the two sides (There is degeneration of lumbosacral multifidus muscle on the affected side of patients with unilateral L
