70 cases of Lumbar Spinal Canal Stenosis were operated on for past 2 years.
Clinical and roentgenographic investigations were performed about 43 cases of these operative cases and histological examinations of lig. flavum were performed about 9 cases.
[Results]
1. Most of cases were from 40 to 69 years old. As the operative findings, there were hyperplasia of lig. flavum at 82%.
2. The measurement of canal to body ratio revealed 1: 4.0 in lumbar stenosis.
3. Histological findings of ligament flavum revealed calcification in 7 cases. Calcification was seen in connective tissue. The elastic fiber obviously revealed degenerative changes.
