摘要

目的

探讨术前颈长肌容积与脊髓型颈椎病（CSM）患者颈椎前路椎间盘切除融合术（ACDF）疗效的关系。

方法

选取2022年9月至2023年9月我院收治的151例拟行ACDF治疗的CSM患者，术前均接受磁共振（MRI）扫描测量颈长肌容积，根据术后12个月的手术疗效将患者分为疗效优秀组和疗效欠佳组。采用日本骨科协会（JOA）评分、颈椎病临床评价量表（CASCS）、颈椎功能障碍指数（NDI）评价患者颈椎功能恢复情况。采用

Pearson

分析术前颈长肌容积与术后颈椎功能的相关性。采用多因素

Logistic

回归分析影响CSM患者ACDF疗效的因素，采用受试者工作特征（

ROC

）曲线分析术前颈长肌容积预测CSM患者ACDF疗效的价值。

结果

151例患者中失访2例，其余149例CSM患者中手术疗效优83例，良32例，可30例，差4例。疗效欠佳组患者术前颈长肌容积小于疗效优秀组（

0.05），术后JOA、CASCS评分低于疗效优秀组（

0.05），NDI评分高于疗效优秀组（

0.05）。CSM患者术前颈长肌容积与术后JOA、CASCS评分呈正相关（

=0.512、0.423，

0.05），与NDI评分呈负相关（

=-0.597，

0.05）。多因素

Logistic

回归分析显示，术后椎间隙高度增加、术前颈长肌容积较大是CSM患者ACDF疗效的保护因素（

0.05）。术前颈长肌容积预测CSM患者ACDF术后疗效的临界值为8 265.82 mm

，曲线下面积为0.895，敏感度为90.70%，特异度为87.30%。

结论

CSM患者术前颈长肌容积偏小与ACDF疗效不佳有关，术前通过MRI测量颈长肌容积或可作为评估ACDF疗效的一个潜在参考指标。

Abstract

Objective

To explore the relationship between preoperative longus colli muscle volume and the postoperative efficacy of anterior cervical discectomy and fusion （ACDF） in patients with cervical spondylotic myelopathy （CSM）.

Methods

A total of 151 CSM patients who scheduled to undergo ACDF treatment in our hospital from September 2022 to September 2023 were selected.All patients received magnetic resonance imaging （MRI） scans before surgery to measure the volume of the longus colli muscle. The patients were divided into the excellent efficacy group and the poor efficacy group according to the surgical efficacy at 12 months postoperatively.The Japanese Orthopaedic Association （JOA） score，clinical

assessment scale for cervical spondylosis （CASCS），and neck disability index （NDI） were used to evaluate the recovery of the cervical spine function of patients.

Pearson

analysis was performed to assess the correlation between preoperative longus colli muscle volume and postoperative cervical spine function.Multivariate

Logistic

regression was used to analyze the factors affecting the therapeutic efficacy of ACDF in CSM patients.The

receiver operating characteristic

（

ROC

） curve was used to analyze the value of preoperative longus colli muscle volume in predicting the therapeutic efficacy of ACDF in CSM patients.

Results

Of the 151 patients，2 were lost to follow-up.Among the remaining 149 CSM patients after ACDF，83 had excellent outcome，32 good，30 acceptable，and 4 poor. In the poor efficacy group，the preoperative longus colli muscle volume was smaller than that in the excellent efficacy group （

0.05）， the postoperative JOA and CASCS scores were lower than those in the excellent efficacy group （

0.05），while the NDI score was higher than that in the excellent efficacy group （

0.05）.The preoperative longus colli muscle volume in CSM patients was positively correlated with the postoperative JOA and CASCS scores （

=0.512，0.423，

0.05），and negatively correlated with the NDI score （

=-0.597，

0.05）.Multivariate

Logistic

regression analysis showed that increased postoperative intervertebral space height and larger preoperative longus colli muscle volume were protective factors for ACDF efficacy in patients with CSM （

0.05）.The critical value of preoperative longus colli muscle volume for predicting the postoperative efficacy of ACDF in CSM patients was 8 265.82 mm³，with an

area under the curve

of 0.895，a sensitivity of 90.70%，and a specif

icity of 87.30%.

Conclusion

Smaller preoperative longus colli muscle volume in CSM patients is associated with poor efficacy of ACDF.Preoperative measurement of longus colli muscle volume by MRI may serve as a potential reference indicator for evaluating the efficacy of ACDF.
