【 摘 要 】
Spinal canal measurements obtainned from radiographic imaging studies are an integral part of diagnostic evaluation of cervical spine stenosis. Before abnormal spinal morphometry can be determined, it is first necessary to establish normal values for the specific patient population being evaluated. Cervical spinal canal stenosis increase risk of quadriplegia after "minor trauma" in the head or neck, mainly in athletes who participate in contact or collision sports. Prospective and random selection of 500 plain film of the lateral cervical spine in young militaries population in age group 18-20 years old. Those were performed a hundred set of film were for each geographic region, including Manaus, Recife, São Paulo, Porto Alegre and Campo Grande. The first part of this study established normal values for cervical morphometry. The second part determined the most accurate screenning method for detecting cervical spinal stenosis. Normal spinal canal mean value for C3 was 18,27mm, C4 17,98mm, C5 18,33mm and 18,76mm in C6. The TORG ratio was evaluated as a method to detect significant cervical spinal stenosis and was shown to have sensitivity and high positive predictive value. It was observed TORG's ratio of 0,80 or less in 14,4% of the X-rays.
