“…Although cervical subluxation has been previously reported in sheep (4), all such cases involved varying degrees of ventrodorsal rotation of C7 and T1, and were later confirmed to be associated with congenital myopathy of the dorsum and neck by pathological examination (3). The upper cervical spine injuries caused by blunt force trauma in the present case were similar to that in a previously reported case of atlanto-occipital subluxation in a goat (14). However, the sheep in this case demonstrated extensive injuries including multiple subluxations and atlanto-occipital fusion.…”

“…In human medicine, it has been suggested that upper cervical spine injuries respond best to surgical stabilization (5). Although surgical repair of injuries to the cervical vertebrae is not performed routinely in farm animals, surgical fixation was conducted in the above-mentioned case by Sorjonen et al (14), but resulted in an unsatisfactorily outcome with mild tetraparesis. In assessing the possibility for such a surgical treatment in sheep, financial constraints and the efficacy of surgical repair must be considered and the decisions to use surgical intervention may vary among farm owners.…”

“…Although anterior cervical subluxation occurs usually as result of flexion-rotation injury in human beings (2,5,12), cervical subluxation caused by trauma has rarely been recorded in ruminants (16). Only one previous report has described a case of atlantooccipital subluxation caused by traumatic injury in an adult goat (14). Other cases of cervical subluxations in small ruminants de -monstrated evidence in association with congenital defects (3,4,13).…”

A 5-month-old, 13.5 kg, female Corriedale sheep was referred to the Veterinary Medicine Teaching Hospital, with a history of traumatic injury of the cervical spine followed by non-ambulatoric tetraparesis that occurred 2 weeks before being admitted to the hospital. At admission, malalignment of the cervical spine with the cranial part of the neck deviating to the right was noted. Neurological examinations identified the absence of postural reactions in both forelimbs, mildly decreased spinal reflexes, and normal reaction to pain perception tests. Radiography revealed malalignment of the cervical vertebrae with subluxations at C1-C2 and C2-C3, and a comminuted fracture of the caudal aspect of C2. The sheep was euthanized due to a presumed poor prognosis. Necropsy and histopathological findings confirmed injuries of the cervical spine from C1 to C3, which were consistent with the clinical finding of tetraparesis in this case. This paper presents a rare case of multiple subluxations of the cervical spine caused by blunt force trauma in a young sheep. These results highlight the importance of an astute clinical diagnosis for such an acute cervical spine trauma and the need for prompt surgical correction for similar cases in the future.

In a 7-week-old calf neurologic symptoms occurred after an accident in the feeding grid. The calf was alert but in left lateral recumbency. After having been placed on its right side it showed a sideward drift to the left. Following head movement, an asynchronous movement of the eyes could be observed. Lesions of the upper motor neuron system, N. vestibulocochlearis, Nn. oculomotorius, trochlearis and/or abducens as well as N. vagus were suspected. Radiological examination of the occipi tal region and cervical spine revealed an atlanto-occipital subluxation of the atlas. Based on all these findings, the diagnosis of traumatic atlanto-occipital dislocation was made and the calf was euthanized.

“…[266][267][268][269][270] The luxations can be managed with conservative therapy in which the luxation is manual reduced and a cast with the neck in flexion is applied or with surgical stabilization. Traumatic luxations of the occipitoatlantal articulation are rare.…”
