The study aims to investigate the effects of aging on the cervical spine.Outpatients in the study were grouped by age. The cervical spine image in the sagittal plane from participants in the supine position was acquired with MRI. Thoracic inlet angle (TIA), T1 slope (T1S), neck tilt (NT), and cervical angle (CC2-7) were measured.NT and TIA measured 41.84 ± 9.26 and 64.15 ± 10.72 in participants younger than 40, and 53.02 ± 9.52 and 72.09 ± 10.49 in participants older than 40 (P < .01). CC2-7 measured 6.11 ± 9.88 in participants younger than 40, significantly lower compared with participants older than 40, which measured 10.89 ± 11.02 (P = .003). TIS did not differ significantly between the 2 groups (P = .087). No significant difference was found in all measurements between the female and male participants. Age was moderately correlated with NT (r = 0.466, P < .01) and TIA (r = 0.512, P < .01), but weakly correlated with CC2-7 (r = 0.315, P < .01) and TIS (r = 0.210, P = .005). TIA showed a strong correlation with NT (r = 0.748, P < .01) and a moderate correlation with T1S (r = 0.458, P < .01). Lastly, T1S was strongly correlated with CC2-7 (r = 0.701, P < .01).The result showed that NT, CC2-7, and TIA, but not T1S, increased with age.
该研究旨在调查衰老对颈椎的影响。研究中的门诊患者按年龄分组。通过MRI获取参与者仰卧位时矢状面的颈椎图像。测量胸廓入口角（TIA）、T1斜率（T1S）、颈部倾斜度（NT）和颈椎角（CC2-7）。40岁以下参与者的NT和TIA分别为41.84±9.26和64.15±10.72，40岁以上参与者的NT和TIA分别为53.02±9.52和72.09±10.49（P<0.01）。40岁以下参与者的CC2-7为6.11±9.88，显著低于40岁以上参与者，40岁以上参与者的CC2-7为10.89±11.02（P=0.003）。两组之间的TIS无显著差异（P=0.087）。女性和男性参与者在所有测量中均未发现显著差异。年龄与NT（r=0.466，P<0.01）和TIA（r=0.512，P<0.01）中度相关，但与CC2-7（r=0.315，P<0.01）和TIS（r=0.210，P=0.005）弱相关。TIA与NT（r=0.748，P<0.01）强相关，与T1S（r=0.458，P<0.01）中度相关。最后，T1S与CC2-7（r=0.701，P<0.01）强相关。结果表明，NT、CC2-7和TIA随年龄增长而增加，但T1S并非如此。
