摘要:

文题释义:
退变性胸腰段后凸:胸腰段椎体后凸的严重程度由胸腰椎后凸角表示,即T10上终板和L2下终板之间的角度,正常值为(0±15)°,退变性胸腰段后凸为可明确的由退变因素所致的胸腰椎后凸角≥15°者。
腰背肌肉凹陷值:首次由日本学者TAKAYAMA于2016年提出,即测量棘突顶点至两侧椎旁肌表面顶点连线的距离以代替腰背肌肉含量,在核磁上分别测量从T12-L1到L4-L5椎间隙即可获得。

背景:目前退变性胸腰段椎体后凸患者胸腰段后凸程度和脊柱后方肌群含量之间的关系尚未明确。近年来,为简化脊柱后方肌群含量的测量程序,腰背肌肉凹陷值作为新概念被引入。
目的:分析退变性胸腰段后凸患者椎旁肌肉含量的分布特点,并探讨胸腰椎后凸程度与体质量指数及椎旁肌肉含量的关系。
方法:回顾性分析南京市溧水区人民医院脊柱外科2015年6月至2020年6月收治的90例退变性胸腰段后凸患者(退变性胸腰段后凸组)和62例无脊柱畸形的健康志愿者(对照组)的临床资料,两组在人口统计学方面匹配。在两组患者全脊柱X射线正侧位片上获取胸腰椎后凸角和腰椎前凸角;使用简便的腰背肌肉凹陷值作为评估腰背肌群含量的参数,在T2加权MRI轴位片上分别测量从T12-L1到L4-L5节段的腰背肌肉凹陷值。两组根据体质量指数分为正常体质量、超重和肥胖亚组;退变性胸腰段后凸患者分为腰椎前凸角升高、正常腰椎前凸角和腰椎前凸角减小3个亚组。
结果与结论:①退变性胸腰段后凸组平均腰背肌肉凹陷值小于对照组(P < 0.01);从T12/L1到L4/L5节段,腰背肌肉凹陷值在两组均呈递增趋势(P < 0.01);②对照组男性平均腰背肌肉凹陷值大于女性(P < 0.05),且平均腰背肌肉凹陷值在体质量正常组小于超重组和肥胖组(P < 0.05);③退变性胸腰段后凸组平均腰背肌肉凹陷值在性别方面对比差异无显著性意义;退变性胸腰段后凸组T12-L1和L1-L2的腰背肌肉凹陷值在不同体质量指数亚组间相比差异有显著性意义(P=0.003,P=0.009);退变性胸腰段后凸组中,平均腰背肌肉凹陷值在腰椎前凸角增大亚组大于腰椎前凸角正常亚组和腰椎前凸角减小亚组(P < 0.01);④胸腰椎后凸角与体质量指数在两组内均无明确相关性;对照组中体质量指数与平均腰背肌肉凹陷值呈正相关(P=0.003),且存在平均腰背肌肉凹陷值= 0.32×体质量指数;退变性胸腰段后凸组中胸腰椎后凸角与平均腰背肌肉凹陷值呈负相关(P < 0.001),且存在平均腰背肌肉凹陷值= 13.75-0.48×胸腰椎后凸角;两组整合后存在平均腰背肌肉凹陷值=5.45+0.21×体质量指数-0.41×胸腰椎后凸角;⑤提示退变性胸腰段后凸患者的腰背肌肉含量小于正常人群;胸腰椎后凸程度和体质量指数无关,而与腰背肌含量可相互预测。

Abstract: BACKGROUND: The relationship between the content of paraspinal muscle and kyphotic severity in patients with degenerative thoracolumbar kyphosis has not been determined yet. Recently, a fresh concept of lumbar crossing indentation value was introduced as a simple method for the measurement of paraspinal muscle.  
OBJECTIVE: To identify the characteristics of lumbar paraspinal muscles in patients with degenerative thoracolumbar kyphosis, and to explore the relationship between thoracolumbar kyphosis and body mass index and between thoracolumbar kyphosis and the content of lumbar paraspinal muscles.
METHODS:  Totally 90 patients with degenerative thoracolumbar kyphosis (degenerative thoracolumbar kyphosis group) and 62 volunteers without spine deformity (control group) were retrospectively enrolled from June 2015 to June 2020 in the Department of Spine Surgery, Lishui District People’s Hospital with well-matched demographics. The two groups were matched in terms of demographics. Thoracolumbar kyphosis and lumbar lordosis were obtained on the X-ray of the whole spine. Lumbar crossing indentation value was introduced to evaluate the content of the lumbar paraspinal muscles, which was measured from T12-L1 to L4-L5 at T2-MRI axial imaging. Both groups were separately divided into three subgroups of normal weight, overweight and obesity according to body mass index. Degenerative thoracolumbar kyphosis patients were divided into three subgroups of increased lumbar lordosis, normal lumbar lordosis and decreased lumbar lordosis.  
RESULTS AND CONCLUSION: (1) The mean lumbar crossing indentation value in degenerative thoracolumbar kyphosis group was less than control group (P < 0.01). Lumbar crossing indentation value showed an increasing trend from T12/L1 to L4/L5 in both groups (P < 0.01). (2) In control group, mean lumbar crossing indentation value in male was larger than that in female (P < 0.05) and mean lumbar crossing indentation value in normal group was less than ones with overweight or obesity (P < 0.05). (3) In the degenerative thoracolumbar kyphosis group, mean lumbar crossing indentation value was not significantly different in both sexes. Significant differences were found in lumbar crossing indentation value in T12-L1 and L1-L2 at different body mass indexes (P=0.003, P=0.009). In degenerative thoracolumbar kyphosis group, mean lumbar crossing indentation value in lumbar lordosis-increased subgroup was larger than that of lumbar lordosis-normal and lumbar lordosis-decreased subgroups (P < 0.01). (4) There was no relationship between thoracolumbar kyphosis and body mass index in both groups. Body mass index was positively correlated to mean lumbar crossing indentation value in control group (P=0.003) with mean lumbar crossing indentation value=0.32×body mass index. Thoracolumbar kyphosis and mean lumbar crossing indentation value were negatively correlated (P < 0.001) in degenerative thoracolumbar kyphosis group with lumbar crossing indentation value=13.75-0.48× thoracolumbar kyphosis. For all cases, there was a relationship of mean lumbar crossing indentation value= 5.45+0.21× body mass index -0.41× thoracolumbar kyphosis. (5) It is indicated that degenerative thoracolumbar kyphosis patients had a less lumbar crossing indentation value than controls. There was no relationship between the severity of thoracolumbar kyphosis and body mass index, while lumbar crossing indentation value and thoracolumbar kyphosis were mutually predictable.

Key words: degenerative thoracolumbar kyphosis, body mass index, lumbar crossing indentation value, lumbar lordosis, lumbodorsal muscle
