Veterinary Chiropractic Treatment as a Measure to Prevent the Occurrence of Spondylosis in Boxers

Spondylosis deformans is a spinal disease common to several dog breeds, and several treatments including veterinary chiropractic may be used to treat affected dogs. Little is known, however, about the efficacy of chiropractic treatment as precautionary measure, aiming to reduce the probability of spondylosis development. We performed a randomized study where one half of the Boxer puppies from 17 litters were given veterinary chiropractic treatment at monthly intervals from eight weeks of age until they were one year old, while the other half were given no treatment (treated: n = 44, controls: n = 43). At an age of one year, spondylosis occurrence was recorded based on a scoring of X-ray images of the spine. The frequency of occurrence was significantly lower (p = 0.0478) in the treated dogs (25.0%) than in the controls (46.5%). We also tested if spondylosis occurrence in the treated dogs correlated with the average number of spinal joints with decreased mobility found per chiropractic treatment. No such effect was found, however. In summary, our results suggest that veterinary chiropractic treatment may be successfully used to reduce the probability of early development of spondylosis in young Boxers.

Radiographic lumbosacral vertebral abnormalities and constipation in cats

Background and Aim: Lumbosacral intervertebral disk disease (IVDD) in cats usually develops concurrent with constipation, spondylosis deformans, and sacralization. However, the prevalence of lumbar IVDD in cats was considered low, and there was less information on the incidence of non-traumatic lumbosacral vertebral abnormalities that may affect large bowel dysfunction. This study aimed to retrospectively investigate the relationship between non-traumatic lumbosacral vertebral abnormalities, both congenital and acquired, and large bowel dysfunction in cats. Materials and Methods: Of 3108 cats that were presented to the Diagnostic Imaging Unit, the Small Animal Teaching Hospital, Faculty of Veterinary Science, Chulalongkorn University, between March 2016 and February 2018, 1365 cats met the inclusion criteria. All abdominal radiographs were reviewed, and all subsequent data were recorded, including the presence of congenital or acquired lumbosacral lesions, number of lumbar vertebrae, and length of the second, fifth, and last lumbar vertebrae, including the type of lumbar abnormalities. Moreover, radiographic information relating to constipation and megacolon was also collected. Results: Non-traumatic lumbosacral vertebral abnormalities were observed in 29.74% of cats. The most common congenital lumbosacral vertebral abnormalities were six lumbar vertebrae, sacralization, and lumbarization, whereas most common acquired lumbosacral abnormalities were bone spur, narrowing disk space, spondylosis deformans, and lumbosacral degeneration, respectively. Cats with abnormal lumbosacral vertebrae are prone to have more problems with the large bowel (p=0.0057; odds ratio=1.731). Moreover, congenital and acquired lumbosacral abnormalities were also at risk of large bowel abnormalities (p=0.0069; odds ratio=1.920 and p<0.0001; odds ratio=4.107, respectively). Conclusion: This study revealed the evidence and distribution of the variation in feline lumbar anatomy and also elucidated that cats with abnormal lumbar vertebral columns were more likely to have problems with distal gastrointestinal tracts than those without.

A Case of Thoracic Spondylosis Deformans and Multilevel Instrumented Spinal Fusion in an 84-Year-Old Male

Spondylosis deformans is a type of spinal claw osteophytosis which can be found on the anterolateral vertebral bodies of any region, and which consists of protrusions of intervertebral disc tissue covered by a bony shell. We report here a case of thoracic spondylosis deformans and multilevel instrumented fusion found during routine dissection of a cadaver. Theories of the etiology of this condition are reviewed in general, and with respect to this specific case and the potential interaction of the presenting comorbidities. The clinical implications of these osteophytes, including musculoskeletal and visceral sequelae, are also discussed.

Prevalence of Spondylosis Deformans in Tailed Versus Tail-Docked Rottweilers

ABSTRACT Tail docking is a routine procedure for rottweilers in the United States and Canada. A cross-sectional comparative study was conducted in tailed (n = 25) and docked (n = 39) rottweilers ≥5 yr old to compare prevalence and severity of spondylosis deformans in the lumbar spine between groups. The prevalence of spondylosis was 68.0% in tailed dogs and 76.9% in docked dogs, which was not significantly different (P = .563). Distribution of spondylosis severity did not significantly differ between tailed and docked dogs (P = .102). Logistic regression found moderate to severe spondylosis was associated with age and sex. Females were three times at greater risk than males (odds ratio 3.10, 95% confidence interval 1.060–9.08; P = .039). Risk increased 1.4 times for each additional year (odds ratio 1.43, 95% confidence interval 1.02–1.99, P = .036). Tail docking may not impact or only play a minor role in spondylosis deformans in rottweilers.

Posterior ataxia-paraparesis syndrome in the large-breed dog

The most common conditions associated with the posterior ataxia-paraparesis syndrome in large breed dogs are degenerative myelopathy, type II intervertebral disk disease, spinal cord neoplasms (extradural, extramedullary, intradural, intramedullary), cervical vertebral malformation-malarticulation, lumbosacral spondylopathy, diskospondylitis and distemper myelitis. These progressive myelopathies, which are often seen in aging dogs, are characterized clinically by posterior ataxia and UMN and/or LMN paraparesis that may result in paraplegia late in the course of the disease. In a certain number of cases the clinical picture is further deteriorated by concomitant hip dysplasia associated with osteoarthritis. Spinal radiography of myelopathic dogs may reveal spondylosis deformans or dural ossification to which their clinical signs could be erroneously attributed. Lesions of the spinal cord are localized and their etiology is determined with the aid of radiography, myelography, CT or MRI, CSF analysis and electrodiagnostic examination (somatosensor evoked potentials, electromyogram). In general, the various therapeutic modalities (decompressive surgeries, medication, exercise, physical therapy, avoidance of the complications associated with prolonged recumbency) usually applied in these cases are also discussed.
