요추관 협착증 환자에서 단순 요추방사선 촬영의 진단적 가치에 관한 통계학적 연구 = Statistical Analysis of Lumbar Canal Stenosis Patients

다국어 초록 (Multilingual Abstract)

To evaluate the diagnostic advantages of simple lumbar X-ray and clinical features on the lumbar canal stenosis patients, we conducted the study upon the 40 lumbar canal stenosis patients, who were treated at the department of neurosurgery in a general hospital in Seoul, from January 1980 to October 1984.
The results of the study were as follows:
1. Of the total 40 patients, the sex ratio was nealy 1, most patients were over forty, and 62.5% of them have been suffered from illness more than one year.
2. Main symptoms and signs were radiating leg pain, backward bending limitation, intermittent claudication motor weakness, in that order.
3. The frequent narrowing vertebral level was L_4~5, as 85.0%.
4. On simple lumbar X-ray, the anteroposterior of spinal canal was 4mm in diameter shorter in patient group, contrast with normal control group. But that was 3mm shorter in interpedicular distance. The difference of diameter and distance were statistically significant.
5. The main myelographic findings were complete and almost complete block, the levels were the site disc space.
