The twenty-five patients with the intermittent claudication syndrome of th cauda equina included 19 men and 6 women aged from 23 to 70 years. The results of operation were very good in 16 cases, with improvement in 6 others and failure in 3 cases. There are various mechanisms which can cause the stenosis. The authors stress the importance of congenital vertebral abnormalities and the presence of apophyseal appendices which, at the present time, have not been considered responsible.
