摘要

A 73-year-old woman presented to the spine clinic with low back pain, neurogenic claudication, and radiculop-athy. Panoramic anteroposterior X-rays demonstrated degenerative scoliosis with a primary left-convex lumbar curve estimated at 43.2° and a secondary compensatory thoracic curve of 35°. In addition to multilevel central canal and lateral recesses stenosis, the magnetic resonance imaging of the lumbar spine demonstrated significant atrophy of the paraspinal muscles at the concave side of the curve, which were more marked at its apex (level L2/L3) (Figure). This is consistent with a recent magnetic resonance imaging study that demonstrated that, in patients with degenerative lumbar scoliosis, the cross-sectional area of the multifidus muscle is significantly smaller, and the percentage of fat infiltration of both the multifidus and longissimus muscles is significantly higher on the concave side of the curve at all levels [1]. In another study, it has been demonstrated that, on biopsy, there is a significantly lower proportion of Type I (slow-twitch oxidative) fibers in the paraspinal muscles on the concave side of scoliotic curves, suggesting that the paraspinal muscles on this side adopts a "faster" (or more "glyco-lytic") profile [2], which is compatible with reduced muscle activity induced by the deformity
