Abstract

PURPOSE We aimed to investigate the prevalence of lumbar multifidus muscle (LMM) atrophy in patients having mechanical low back pain with and without disc hernia. METHODS In total, 2028 lumbar magnetic resonance imaging scans of low back pain patients (age range, 18-88 years) were re-evaluated retrospectively. LMM atrophy was visually assessed in axial sections of L4-L5 and L5-S1 levels. RESULTS LMM atrophy prevalence at both levels was significantly higher in subjects ≥40 years compared with younger adults (P < 0.001). LMM atrophy was significantly more frequent in women than in men (P < 0.001). Among patients with low back pain without hernia, LMM atrophy was significantly more frequent than normal muscle (n=559 vs. n=392; P < 0.001). Frequency of LMM atrophy in low back pain patients without disc hernia was 13%. Hernia was more frequent in patients with LMM atrophy compared with patients without atrophy (P < 0.001). CONCLUSION LMM atrophy is more common in women; its prevalence and severity are observed to increase with advancing age, and disc hernia is found more frequently in individuals with LMM atrophy.

2028例腰椎多裂肌萎缩与椎间盘突出共存的年龄和性别分布的MRI研究

目的:研究伴有或不伴有椎间盘突出的机械性腰痛患者腰多裂肌(LMM)萎缩的发生率。方法回顾性分析2028例腰痛患者(年龄18-88岁)的腰椎磁共振成像扫描结果。在L4-L5和L5-S1水平轴向切片上视觉评估LMM萎缩。结果≥40岁受试者的两种水平的slmm萎缩患病率均显著高于年轻成人(P < 0.001)。LMM萎缩在女性中明显多于男性(P < 0.001)。在无疝的腰痛患者中，LMM萎缩明显高于正常肌肉(n=559 vs. n=392;P < 0.001)。无椎间盘突出的腰痛患者LMM萎缩的发生率为13%。LMM萎缩患者疝发生率高于无萎缩患者(P < 0.001)。结论lmm萎缩以女性多见;其患病率和严重程度随着年龄的增长而增加，椎间盘突出更常见于LMM萎缩的个体。
