The evaluation by means of functional x-rays, of rotatory instability of the upper cervical spine as a result traumatic or inflammatory destruction of the ligamentous apparatus, is unsatisfactory. Functional CT of the upper cervical spine allows measurement of the segmental rotatory movements. 9 healthy adults and 30 patients were examined after neck injury via functional CT's. A rotation between occiput and atlas greater than 9 degrees, between atlas and axis over 50 degrees, the left-right difference at the level C0/C1 greater than 6 degrees and at the level C1/C2 over 10.5 degrees point to a suspicion of hypermobility or instability.
通过功能X线对由于韧带装置的创伤性或炎性破坏导致的上颈椎旋转不稳定进行评估，结果并不理想。上颈椎的功能CT能够测量节段性旋转运动。对9名健康成年人和30名颈部受伤患者进行了功能CT检查。枕骨与寰椎之间的旋转角度大于9度、寰椎与枢椎之间大于50度、C0/C1水平的左右差异大于6度以及C1/C2水平大于10.5度提示存在活动过度或不稳定的嫌疑。
