Their plain x-ray films were read as normal and myelograms demonstrated a ventral defect at L4\u20135. Surgical exploration revealed ventral bony ridges in both cases. Laminectomy initially provided substantial relief, but spinal fusion was necessary for complete abolition of symptoms.<\/jats:p>","DOI":"10.3171\/jns.1978.49.3.0441","type":"journal-article","created":{"date-parts":[[2009,5,7]],"date-time":"2009-05-07T15:25:00Z","timestamp":1241709900000},"page":"441-444","source":"Crossref","is-referenced-by-count":2,"title":["Congenital lumbar ridge causing spinal claudication in adolescents"],"prefix":"10.3171","volume":"49","author":[{"given":"Ronald","family":"Birkenfeld","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David L.","family":"Kasdon","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Spine","doi-asserted-by":"publisher","first-page":"75","DOI":"10.1097\/00007632-197703000-00010","article-title":"Intermittent cauda equina compression syndrome.
