Dorsal laminectomy in the treatment of cervical intervertebral disk disease in small dogs: a retrospective study of 30 cases

Abstract

Dorsal laminectomy was used to treat 30 dogs with cervical intervertebral disk disease. A variety of breeds were represented, and all animals weighted 15 kg or less. Myelography was utilized to locate each solitary disk herniation. All 30 cases progressed to complete recovery which indicates that dorsal laminectomy may be performed with success in small dogs with intervertebral disk disease.

A Retrospective Study of Intervertebral Disc Herniation in Dogs in Japan: 297 Cases

“…This data is in agreement with past reports [4,8,11]. The degree of neurological deficit of the dogs in the C-IVDH group included in this study is in close agreement with that found in a previous retrospective study of IVDH in that grades 3, 2 and 1 made up 17%, 30% and 53% of the study population, respectively [11]. The characteristics of the disease in the predominant dog breeds in the C-IVDH group in Japan, the Beagle, Dachshund and Shih Tzu, were analyzed.…”

“…The rate of this disorder in the Beagle is clearly larger in Japan than in other countries, and this may reflect the Beagle breeding rate in Japan. Age at admission in this study was in agreement with previous data that indicated a range of 7.4 to 8.2 years of age [4,8,11,28]. In the current study, females made up 37.1% of the C-IVDH group and males made up the other 62.9%, and these results indicate that male dogs are almost twice as likely as females to suffer C-IVDH.…”

“…The breeds most frequently suffering from C-IVDH were the Beagle (34.8%) followed by the Dachshund (12.9%). Similar results have been reported previously, showing that the Dachshund (12.5%-43.3%) and Beagle (6.7%-17.5%) were the most frequent sufferers of C-IVDH, although the order was different from our results [4,8,11,28]. The rate of this disorder in the Beagle is clearly larger in Japan than in other countries, and this may reflect the Beagle breeding rate in Japan.…”

“…The localization of the affected interspace was based on myelography, CT, CT-myelograph or MRI. The grade of myelopathy in the C-IVDH group was divided into the following three categories based on neurological status according to a previous study [11] with minor modifications: grade 1, normal ambulation with neck pain; grade 2, ambulatory tetraparetic with neck pain; grade 3, nonambulatory tetraparetic. The grade of myelopathy in the TL-IVDH group was divided into the following five categories according to a previous study [24]: Grade I, spinal hyperesthesis only; Grade II, mild ataxia with motor function adequate for weight support; Grade III, severe ataxia with motor function inadequate for weight support; Grade IV, paralysis of the hind limb with intact deep pain sensation; Grade V, paralysis of the hind limb with no deep pain sensation.…”

Risk factors for early post-operative neurological deterioration in dogs undergoing a cervical dorsal laminectomy or hemilaminectomy: 100 cases (2002–2014)

“…other studies have reported more favourable outcomes with limited hospitalisation and 60 recovery times (Gill et al, 1996;Faissler, 2011, De Decker et al, 2012a Further information recorded included signalment, bodyweight, duration of clinical signs 82 prior to surgery (acute <48 h, subacute 2-7 days and chronic >7 days), diagnosis, type, 83 location, extent (number of vertebrae operated on) and duration of the surgery, presence of 84 perioperative complications during the period of hospitalisation and hospitalisation time.
