All dogs exhibited low back pain and varying degrees of asymmetrical cauda equina dysfunction. Results of myelography, epidurography, and magnetic resonance imaging (MRI) indicated a unilateral disk protrusion in all dogs. In the dogs with MRIs, focal degenerative alterations in the vertebral end plates and adjacent body of the vertebra were detected. All dogs were treated with a dorsal laminectomy or hemilaminectomy. Results following surgery were good or excellent in all six dogs.<\/jats:p>","DOI":"10.5326\/0400338","type":"journal-article","created":{"date-parts":[[2014,9,15]],"date-time":"2014-09-15T12:05:47Z","timestamp":1410782747000},"page":"338-344","source":"Crossref","is-referenced-by-count":13,"title":["Asymmetrical, Transitional, Lumbosacral Vertebral Segments in Six Dogs: A Characteristic Spinal Syndrome"],"prefix":"10.5326","volume":"40","author":[{"given":"Frank","family":"Steffen","sequence":"first","affiliation":[{"name":"Department of Small Animals, Section of Small Animal Surgery\/Neurology (Steffen) and Section of Diagnostic Imaging and Radio-Oncology (Morgan), University of Zurich, Winterthurerstrasse 260, CH-8057 Zurich, Switzerland; and the"},{"name":"Swiss Center for Paraplegics, Institute for Diagnostic Radiology (Berger), CH-6207 Nottwil, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Markus","family":"Berger","sequence":"additional","affiliation":[{"name":"Department of Small Animals, Section of Small Animal Surgery\/Neurology (Steffen) and Section of Diagnostic Imaging and Radio-Oncology (Morgan), University of Zurich, Winterthurerstrasse 260, CH-8057 Zurich, Switzerland; and the"},{"name":"Swiss Center for Paraplegics, Institute for Diagnostic Radiology (Berger), CH-6207 Nottwil, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joe P.","family":"Morgan","sequence":"additional","affiliation":[{"name":"Department of Small Animals, Section of Small Animal Surgery\/Neurology (Steffen) and Section of Diagnostic Imaging and Radio-Oncology (Morgan), University of Zurich, Winterthurerstrasse 260, CH-8057 Zurich, Switzerland; and the"},{"name":"Swiss Center for Paraplegics, Institute for Diagnostic Radiology (Berger), CH-6207 Nottwil, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"3280","reference":[{"key":"R1","series-title":"Vet Clin North Am Small Anim Pract","first-page":"985","volume":"22","year":"1992","unstructured":"Bailey CS, Morgan JP.
