背景背景：颈椎牵引作为颈椎疾病的保守治疗方法有着悠久的历史。然而，缺乏体内轴向牵引引起的颈神经孔定量变化的信息。目的：定量评估体内轴向牵引过程中颈椎神经孔的变化。研究设计：对成年志愿者颈神经孔的前瞻性放射线分析。患者样本：15 名健康志愿者（10 名男性，5 名男性） 结果指标：测量颈椎间孔横断面面积和高度的变化。方法：在中立位拍摄志愿者的颈椎磁共振（MR）图像，并在垂直于C2-3至C6-7水平各神经孔长轴的斜平面上重建。分析了增加轴向牵引力（0、5、10 和 15 kg）时神经孔尺寸的变化。结果：牵引重量每增加 5 kg 后，与未施加重量的位置相比，椎间孔的面积和高度显着增加（p 值小于 0.05）。与无牵引重量5、10、15 kg的体位相比，椎间孔面积平均增加5.81%、16.56%、18.9%，椎间孔高度平均增加3.75%、8.67%、10.43%。牵引10至15公斤前，椎间孔面积和高度的增加没有统计学上的显着差异（p值大于0.05）。结论：牵引重量每增加5公斤后，与没有施加重量的位置相比，椎间孔面积和高度显着增加。从10公斤到15公斤的牵引力，椎间孔面积和高度没有明显变化。由爱思唯尔公司出版
BACKGROUND CONTEXT: Cervical traction has a long history as a method of conservative treatment for cervical spine diseases. However, information oil quantitative changes in the cervical neural foramen resulting from axial traction in vivo is lacking.PURPOSE: To quantitatively evaluate the changes in the neural foramen of the cervical spine during axial traction in vivo.STUDY DESIGN: A prospective radiographic analysis of the cervical neural foramen of adult volunteers.PATIENT SAMPLE: Fifteen healthy volunteers (10 men, 5 women) without any history of cervical spine disease.OUTCOME MEASURES: The changes in cervical cross-sectional foraminal areas and heights were measured.METHODS: Cervical magnetic resonance (MR) images of the volunteers were taken at the neutral position and were reconstructed in the oblique plane perpendicular to the long axis of each neural foramen from the C2-3 to the C6-7 level. The changes in the neural foraminal dimensions at incremental axial traction forces (0, 5, 10, and 15 kg) were analyzed.RESULTS: After each 5-kg incremental increase in traction weight, there was a significant (p value less than .05) increase in area and height of the intervertebral foramen compared with the position in which no weight was applied. There was an average increase of 5.81%, 16.56%, and 18.9% in the foraminal area and an average increase of 3.75%, 8.67%, and 10.43% in foraminal height compared with the position with no weight at traction of 5, 10, and 15 kg, respectively. There was no statistically significant difference for the increase in foraminal area and height front 10 to 15 kg of traction (p value greater than .05).CONCLUSIONS: There was a significant increase in intervertebral foraminal area and height after each 5-kg increment in traction weight compared with the position in which no weight was applied. From 10 to 15 kg of traction, there was no significant change in the foraminal area and height. Published by Elsevier Inc.
