Percentages of dorsal compression of the spinal cord were 28.6%, 31%, and 28.8%.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"s003\">\n<jats:title>TREATMENT AND OUTCOME<\/jats:title>\n<jats:p>All 3 dogs underwent decompressive surgery via a dorsal approach. The AA band was removed, and a durotomy was performed, which resulted in spontaneous drainage of a copious amount of CSF. Grossly, the spinal cord parenchyma appeared normal, other than the dorsal compression. To alleviate the AA instability resulting from removal of the dorsal AA ligament, 2-0 polydioxanone was placed in the dorsal cervical muscles extending from the atlantooccipital joint to C2. Postoperatively, all 3 dogs regained normal ambulation between 18 and 30 days after surgery. No complications were reported, and clinical signs did not recur during follow-up times ranging from 4 to 19 months.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"s004\">\n<jats:title>CLINICAL RELEVANCE<\/jats:title>\n<jats:p>Findings suggested that surgical treatment may be an effective option in managing dogs with a dorsal compressive AA band causing nonambulatory tetraparesis. Notably, all of the dogs had other craniocervical abnormalities, but none of these abnormalities were considered severe enough to have caused tetraparesis.<\/jats:p>\n<\/jats:sec>","DOI":"10.2460\/javma.255.6.700","type":"journal-article","created":{"date-parts":[[2019,9,3]],"date-time":"2019-09-03T15:12:13Z","timestamp":1567523533000},"page":"700-705","source":"Crossref","is-referenced-by-count":3,"title":["Decompressive
