摘要:

目的 探讨基于MRI测量的椎旁肌参数对腰椎间盘突出症(LDH)行经皮椎间孔镜下椎间盘切除术(PTED)患者术后复发的预测价值。方法 选取186例行PTED手术的单节段LDH患者,根据6个月以上的随访结果将患者分为复发组(24例)与未复发组(162例)。收集2组患者基线资料,测量并计算2组多裂肌与竖脊肌的标准化功能性横截面积(SCSA)和脂肪浸润率(FIR),评估脂肪浸润分级。采用多因素Logistic回归分析椎旁肌参数对术后复发的影响,并通过受试者工作特征(ROC)曲线评估其预测效能。结果 复发组的体质量指数(BMI)、糖尿病比例、疼痛视觉模拟量表(VAS)评分、Oswestry功能障碍指数(ODI)、Pfirrmann分级为Ⅳ—Ⅴ级的比例、多裂肌、竖脊肌FIR、严重浸润(2级)人数比例高于未复发组,多裂肌、竖脊肌SCSA小于未复发组(P<0.05)。Firth偏倚校正Logistic回归分析显示,多裂肌与竖脊肌SCSA降低、FIR升高为LDH患者PTED术后复发的危险因素。ROC曲线分析表明,椎旁肌参数联合预测术后复发的ROC曲线下面积(AUC)为0.898(95%CI:0.845~0.937),敏感度为83.3%,特异度为88.3%。结论 基于MRI测量的椎旁肌参数对单节段LDH患者PTED术后复发具有良好的预测价值,可作为术前评估复发风险、识别高危患者并提供个体化干预的指标。

Abstract:

Objective To investigate the independent impact of paraspinal muscle parameters on postoperative recurrence after percutaneous transforaminal endoscopic discectomy (PTED) in patients with lumbar disc herniation (LDH) and to evaluate their predictive value for postoperative recurrence. Methods A total of 186 patients with single-segment LDH who underwent PTED were selected. Patients were followed up for more than 6 months and were divided into the recurrence group (24 cases) and the non-recurrence group (162 cases) based on the follow-up results. Baseline data were collected in the two groups, and the standardized cross-sectional area (SCSA) and fat infiltration rate (FIR) of the multifidus and erector spinae muscles were measured and calculated. The fat infiltration grade was evaluated. Multivariate Logistic regression was used to analyze the influence of paraspinal muscle parameters on postoperative recurrence, and the predictive efficacy was evaluated by the receiver operating characteristic (ROC) curve. Results The body mass index (BMI), proportion of diabetes history, pain visual analogue scale (VAS) score, Oswestry disability index (ODI), proportion of Pfirrmann grade Ⅳ/Ⅴ, FIR of multifidus muscle, FIR of erector spinae muscle, proportion of patients with severe infiltration (Grade 2) of multifidus muscle and erector spinae muscle in the recurrence group were higher than those in the non-recurrence group, while the SCSA of the multifidus and erector spinae muscles were smaller (P<0.05). The difference in fat infiltration degree was statistically significant. The Firth bias-corrected Logistic regression analysis showed that decreased SCSA of the multifidus and erector spinae muscles, increased FIR were all risk factors for postoperative recurrence in LDH patients after PTED. ROC curve analysis indicated that the area under the ROC curve (AUC) of the combined prediction of paraspinal muscle parameters for postoperative recurrence was 0.898 (95%CI: 0.845-0.937), with a sensitivity of 83.3% and a specificity of 88.3%. Conclusion MRI-based measurements of paraspinal muscle parameters demonstrate good predictive value for postoperative recurrence and can serve as useful indicators for preoperative risk assessment, identification of high-risk patients, and guiding individualized intervention strategies.
