The characteristic myelographic evidence was complete obstruction during extension of the spine and release of the block with flexion. The cause of this syndrome is considered to be intermittent bulging of the ligamentum flavum into a narrow spinal canal so as to compress the cauda equina during extension of the back.<\/jats:p>","DOI":"10.3171\/jns.1972.37.1.0083","type":"journal-article","created":{"date-parts":[[2009,5,7]],"date-time":"2009-05-07T14:41:39Z","timestamp":1241707299000},"page":"83-88","source":"Crossref","is-referenced-by-count":37,"title":["Intermittent cauda equina compression due to narrow spinal canal"],"prefix":"10.3171","volume":"37","author":[{"given":"Hiroshi","family":"Yamada","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masaki","family":"Ohya","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tsuguo","family":"Okada","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zenji","family":"Shiozawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Lancet","first-page":"1081","article-title":"Intermittent claudication of the cauda equina.
