Pain perception in the pelvic limbs was considered normal, and there was no evidence of fecal or urinary incontinence in any of the 3 dogs. Radiography and magnetic resonance imaging revealed hemivertebrae with severe dorsoventral stenosis of the vertebral canal resulting in spinal cord compression in 2 dogs and lateral compression in the other.<\/jats:p>\n<jats:p><jats:bold>Treatment and Outcome<\/jats:bold>\u2014Each dog underwent decompressive surgery consisting of dorsal laminectomy or hemilaminectomy and vertebral stabilization by use of combinations of Kirschner wires or threaded external fixator pins plus polymethylmethacrylate bone cement.

results of treatment in these 3 dogs suggest that spinal cord decompression and stabilization of the vertebral column can achieve a satisfactory, functional outcome.<\/jats:p>","DOI":"10.2460\/javma.230.4.532","type":"journal-article","created":{"date-parts":[[2007,2,15]],"date-time":"2007-02-15T12:57:48Z","timestamp":1171544268000},"page":"532-536","source":"Crossref","is-referenced-by-count":33,"title":["Imaging findings and surgical treatment of hemivertebrae in three dogs"],"prefix":"10.2460","volume":"230","author":[{"given":"Nicholas D.","family":"Jeffery","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter M.","family":"Smith","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Catherine E.","family":"Talbot","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1272","reference":[{"key":"ref1","series-title":"Vet Surg","first-page":"203","article-title":"Spinal fixation in dogs using Steinman pins and methylmethacrylate","volume":"13","author":"Blass","year":"1984"},{"key":"ref2","series-title":"Vet Surg","first-page":"143","article-title":"Modfied segmental spinal stabilisation in repair of spinal fractures and luxations in dogs","volume":"15","author":"McAnulty","year":"1986"},{"key":"ref3","series-title":"Vet Rec","first-page":"313","article-title":"Hemivertebra in the dog: clinical and pathological observations","volume":"96","author":"Done","year":"1975"},{"key":"ref4","series-title":"J Small Anim Pract","first-page":"625","article-title":"Congenital and developmental abnormalities of the vertebrae","volume":"20","author":"Wright","year":"1979"},{"key":"ref5","series-title":"Disease mechanisms in small animal surgery","first-page":"950","article-title":"Congenital abnormalities of the spine","author":"Colter","year":"1993"},{"key":"ref6","series-title":"Vet Clin North Am Small Anim Pract","first-page":"985","article-title":"Congenital spinal malformations","volume":"22","author":"Bailey","year":"1992"},{"key":"ref7","series-title":"Textbook of veterinary diagnostic radiology","first-page":"98","article-title":"The vertebrae\u2014canine and feline","author":"Walker","year":"2002"},{"key":"ref8","series-title":"Small animal spinal disorders: diagnosis and surgery","first-page":"319","article-title":"Miscellaneous conditions","author":"Sharp","year":"2005"},{"key":"ref9","series-title":"Fundamentals of veterinary clinical neurology","first-page":"255","article-title":"Diagnostic testing in animals with spinal disease","author":"Bagley","year":"2005"},{"key":"ref10","series-title":"Vet Radiol Ultrasound","first-page":"396","article-title":"The computed tomographic appearance of acute thoracolumbar intervertebral disc herniations in dogs","volume":"41","author":"Olby","year":"2000"},{"key":"ref11","series-title":"J Small Anim Pract","first-page":"491","article-title":"Radiological evaluation of \u201cwobbler\u201d syndrome\u2014caudal cervical spondylomyelopathy","volume":"33","author":"Sharp","year":"1992"},{"key":"ref12","series-title":"Acta Ortho Scand Suppl","first-page":"1","article-title":"A pathologic-anatomical study on disc degeneration in dog, with special reference to the so-called enchondrosis intervertebralis","volume":"11","author":"Hansen","year":"1952"},{"key":"ref13","series-title":"Vet Clin North Am Small Anim Pract","first-page":"171","article-title":"Fractures and luxations of the vertebral column","volume":"22","author":"Shores","year":"1992"}],"container-title":["Journal of the American Veterinary Medical Association"],"original-title":[],"link":[{"URL":"https:\/\/avmajournals.avma.org\/view\/journals\/javma\/230\/4\/javma.230.4.532.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/avmajournals.avma.org\/downloadpdf\/journals\/javma\/230\/4\/javma.230.4.532.xml","content-type":"text\/html","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/avmajournals.avma.org\/downloadpdf\/journals\/javma\/230\/4\/javma.230.4.532.xml","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,3,7]],"date-time":"2025-03-07T13:33:56Z","timestamp":1741354436000},"score":1,"resource":{"primary":{"URL":"https:\/\/avmajournals.avma.org\/view\/journals\/javma\/230\/4\/javma.230.4.532.xml"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007,2,15]]},"references-count":13,"journal-issue":{"issue":"4"},"URL":"https:\/\/doi.org\/10.2460\/javma.230.4.532","relation":{},"ISSN":["0003-1488"],"issn-type":[{"value":"0003-1488","type":"print"}],"subject":[],"published":{"date-parts":[[2007,2,15]]}}}
