This study of 52 patients (27 men) with recent (< 18 months) or chronic (> 18 months) low back and unilateral radicular pain symptoms was undertaken to investigate whether wasting of the paraspinal muscle components is generalised or selective. During the patients' routine computed tomographic lumbar spinal scans a standardised transaxial view was obtained along the upper end-plate of the L4 vertebra, and the cross-sectional areas of the paraspinal muscles and their components, multifidus and erector spinae, estimated. Irrespective of whether the symptoms were recent or chronic, multifidus dimensions were significantly greater on the side ipsilateral to the radicular pain symptoms. The results indicate selective changes of multifidus in these patients and possibly reflect an adaptive response by this muscle, such as to an increased role in stabilising the lumbar spine in the face of overall paraspinal muscle atrophy.
本研究纳入 52 名患者（男 27 名），他们均有近期（<18 个月）或慢性（>18 个月）腰痛和单侧根性疼痛症状，旨在探究脊柱旁肌肉成分的消耗是普遍的还是选择性的。在患者常规腰椎计算机断层扫描过程中，在 L4 椎体上终板处获得标准的横轴位图像，并对脊柱旁肌肉及其成分（多裂肌和竖脊肌）的横截面积进行评估。无论症状是近期还是慢性的，患侧的多裂肌尺寸均明显大于对侧。这些结果表明患者的多裂肌存在选择性变化，这可能反映了该肌肉的适应性反应，例如在面对整个脊柱旁肌肉萎缩时，多裂肌在稳定腰椎方面发挥更大作用。
