The mean age at presentation was 52.1 years (range 41\u201366). All patients but one were male. All had a painful radiculopathic presentation. Relevant discopathy was observed from L2\/3 to L5\/S1, the commonest level being L3\/4. Five were treated within 24 h of presentation, and two within 48 h. Three had concomitant cauda equina syndrome; of these, the first two made a full motor recovery, one by 6 weeks follow-up and the second on the same-day post-op evaluation. Overall, five out of seven cases had full resolution of their ankle dorsiflexion pareses. One patient with 1\/5 power has not improved. Another with 1\/5 weakness improved to normal on the one side and to 3\/5 on the other.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>\n                           <jats:italic>Conclusion<\/jats:italic>\n                        <\/jats:title>\n                <jats:p>When <jats:italic>bilateral<\/jats:italic> foot drop occurs <jats:italic>acutely<\/jats:italic>, we encourage the consideration of degenerative spinal disease. Relevant discopathy was observed from L2\/3 to L5\/S1; aberrant innervation may be at play. Cauda equina syndrome is not necessarily associated with acute bilateral foot drop.
