摘　　要：目的探讨颈椎退行性疾病患者抬下颌及自然体位颈椎侧位X线片测得的颈椎中立位曲度差异。方法选择颈椎退行性疾病患者59例,均拍摄抬下颌及自然体位颈椎侧位X线片。分别测量并比较两种体位X线片O-C_2角及C_(2~7)角。结果抬下颌及自然体位X线片C_(2~7)角分别为-15.3°~50.2°(20.0°±13.4°)、-16.1°~38.2°(11.1°±11.8°),两者比较P<0.01;两种体位C_(2~7)角差值为0.8°~26.6°(8.9°±6.1°),两种体位C_(2~7)角度值呈正相关(r=0.890,P<0.01)。抬下颌及自然体位O-C_2角分别为14.8°~46.8°(31.8°±6.0°)、11.1°~40.9°(27.0°±6.6°),两者比较P<0.01;两种体位O-C_2角差值为-2.4°~12.4°(4.8°±3.3°),两种体位O-C_2角度值呈正相关(r=0.873,P<0.01)。结论颈椎退行性疾病患者抬下颌体位X线片测得的颈椎中立位曲度比实际增大;拍摄颈椎侧位X线片时应采用自然体位。Objective To discuss the difference value of cervical neutral position sagittal alignment between protract chin position and natural position cervical lateral X-ray of the patients with cervical degenerative disease. Methods Fifty-nine patients with cervical degenerative disease were included in this study. Every patient took cervical lateral X-ray with protract chin position and natural position. The O-C2 angle and C2.7 angle were measured and compared on these two kinds of X-rays. Results The C2.7 angle on the protract chin position X-ray was - 15.3-50.2° （20.0°± 13.4° ） which had positive correlation （r = 0. 890, P = 0.000） and significant difference with C2.7 angle on the natural position X-ray -16. 1°- 38.2° （ 11.1°±11.8° ） （ P 〈 0.01 ）. The difference value of C2-7 angle between the two positions was 0.8°-26.6° （ 8.9° ± 6.1°）. The O-C2 angle on the protract chin position X-ray was 14.8°-46. 8° （31.8°± 6.0°） which had positive correlation （r = 0. 873, P = 0.000） and significant difference with O-C2 angle on the natural position X-ray 11.1°-40. 9° （27.0°± 6.6°） （P 〈0.01 ）. The difference value of O-C2 angle between the two positions was -2.4°-12.4° （4.8°± 3.3°）. Conclusion For the patients with cervical degenerative disease, natural position should be used for taking cervical lateral X-ray.
