Henderson, C. S., Story, M. R., & Nout-Lomas, Y. S. (2024). Neck pain but not neurologic disease occurs more frequently in horses with transposition of the ventral lamina from C6 to C7. Journal of the American Veterinary Medical Association, 262(9), 1215-1221.
Abstract
OBJECTIVE
To determine reasons for horses to have neck radiographs performed, the incidence of transposition of the ventral lamina of C6 onto C7 (TC67), and the final diagnoses for all horses. Our hypotheses were to find a similar incidence of TC67, as has been previously reported, and an increased incidence of neck pain and dysfunction in horses with TC67.
ANIMALS
135 horses.
METHODS
Retrospective observational study. Medical records of 135 horses with cervical vertebral column radiographs between 2020 and 2022 were assessed. Patient signalment, reasons for radiographs, radiographic findings, and diagnoses were analyzed. The Shapiro-Wilk test was used for normality determination. Nonparametric tests were used to analyze data.
RESULTS
20% of horses were diagnosed with TC67. Significantly more horses with TC67 were warmblood horses (63%); TC67 was found in 28% of warmblood horses. There was no significant difference in signalment or whether horses were in work between the groups, although significantly more horses with TC67 performed in English disciplines (71%). No differences in reasons for examination or final diagnoses of neurologic disease, cervical orthopedic disease, or lameness were present between groups. In horses with neck pain, TC67 was significantly more common (31%) than in horses without (18%).
CLINICAL RELEVANCE
Our results indicated that TC67 occurs more in warmblood horses. In the small group of horses with neck pain reported, TC67 was more commonly seen than in those without. Given the complexity of this region and the paucity of studies exploring neck pain and neck biomechanics, we suggest the need for standardized prospective studies. Click here to read the full article
As a regular visitor to this site, I would like to share my impressions of the material I have read. The text appears to be scientifically accurate and, at the same time, easy to understand, even if you are not a specialist in veterinary neurology. The clear distinction between pain symptoms in the neck of horses and the absence of neurological disease, which can often be misleading in practice, seems particularly valuable. The reference to a specific study from the Journal of the American Veterinary Medical Association adds weight and credibility to the material, as it is clear that the author relies on verified sources. I am impressed by the calm, analytical style of presentation without sensationalism. Overall, the presentation…
