Cineradiographyによる脊椎異常運動の診断

Diagnosis of Abnormal Spine Motion with Cineradiography

Ⅰ．はじめに

　レントゲン映画を脊椎運動の様相を検討する目的で報告した論文は，その重要性にも拘らず，海外でも散見される程度であり，わが国での報告は見当らない．われわれは，過去約1年間，脊椎のレントゲン映画を撮影し，これが脊椎運動の診断に，極めて有用であったので紹介したい．

For the past one year, 13 patients were studied 20 times with cineradiography to diagnose abnormal spine motion, which was quite informative compared to usual plain spine X-ray pictures. The direct radiation dosis was only 2.35 rem/min on taking cineradiography at the speed of 60 frames/sec. The camera used was Car-doskop-U and the X-ray generator was Pandoros Opti-matic, both of which were of Siemens make.

It was keenly recognized that cineradiography was useful to diagnose 1) solidity of spine fusion, 2) effect of spinal traction, 3) efficacy of immobilizing apparatus for spine and 4) abnormal spine motion on dynamic way.
