Limited literature is available to define the impact of the longus colli muscle, a deep flexor of the spine, on cervical spine stability despite its close proximity to the vertebrae.
The purpose of this study was to determine if longus colli cross-sectional area (CSA) is associated with the severity preoperative cervical degenerative spondylolisthesis.
Patients undergoing elective anterior cervical discectomy and fusion (ACDF) for cervical spondylolisthesis between 2010-2021 were retrospectively identified. Longus colli cross-sectional areas (CSA) were measured from preoperative MRI images at the C5 level. Preoperative spondylolisthesis measurements were recorded with cervical radiographs. Patients were grouped by quartiles respectively according to longus colli CSAs. Statistical tests compared patient demographics, surgical characteristics, and surgical outcomes between groups. Multiple linear regression analysis was utilized to assess if longus colli CSA predicted cervical spondylolisthesis.
A total of 157 patients met inclusion criteria. Group 1 (first quartile) was the oldest (60.4 ± 12.0 years, = 0.024) and was predominantly female (59.0%, = 0.001). Group 1 also had the highest maximum spondylolisthesis (0.19 mm, = 0.031) and highest proportion of grade 2 spondylolisthesis (23.1%, = 0.003). On regression analysis, lowest quartile of longus colli CSA was an independent predictor of larger measured maximum spondylolisthesis (β: 0.04, = 0.012).
Smaller longus colli CSA is independently associated with a higher grade and degree of preoperative cervical spondylolisthesis, but this finding does not result in adverse postsurgical outcomes.
尽管颈长肌作为脊柱的深层屈肌与椎体紧邻，但关于其对颈椎稳定性影响的文献有限。
本研究旨在确定颈长肌横截面积（CSA）是否与术前颈椎退变性椎体滑脱的严重程度相关。
回顾性纳入2010年至2021年间因颈椎椎体滑脱接受择期前路颈椎间盘切除融合术（ACDF）的患者。在术前MRI图像上测量C5水平的颈长肌横截面积（CSA）。通过颈椎X线片记录术前椎体滑脱测量值。根据颈长肌CSA将患者分别分为四分位数组。统计检验比较各组患者的人口统计学特征、手术特点和手术结果。采用多元线性回归分析评估颈长肌CSA是否可预测颈椎椎体滑脱。
共有157例患者符合纳入标准。第1组（第一四分位数组）年龄最大（60.4±12.0岁，P = 0.024），且以女性为主（59.0%，P = 0.001）。第1组还具有最高的最大椎体滑脱值（0.19 mm，P = 0.031）和最高比例的2级椎体滑脱（23.1%，P = 0.003）。回归分析显示，颈长肌CSA的最低四分位数是测量的最大椎体滑脱值较大的独立预测因素（β：0.04，P = 0.012）。
较小的颈长肌CSA与术前颈椎椎体滑脱的更高分级和程度独立相关，但这一发现并未导致不良的术后结果
