“…To enable access to lateralised or foraminal discs a lateral approach with hemilaminectomy has been advocated (Lipsitz and Bailey 1992, 1995). Disc localisation diagnostically and surgically can be problematic with the lateral approach and haemorrhage is a possible complication (Rossmeisl and others 2005). The modified slanted slot can be made to one side of the vertebral body allowing for access to one side of the vertebral canal and hence to lateralised disc material, but has limitations because of proximity of the venous plexus.…”

“…Neurological deficits consisted of tetraparesis/ataxia, corresponding to grades 1 or 2 (grade 1: CH or root signature only; grade 2: ambulatory tetraparesis with mild motor deficits) of a previously reported numerical grading system (0 to 5) (Rossmeisl et al . ). Animals with more severe neurological deficits were excluded from the study in order to focus on those cases in which CH had been the main clinical reason for referral.…”

Objectives To describe the prevalence, clinical findings and predictors of disease in dogs with cervical hyperaesthesia. Materials and Methods Medical records of dogs referred for neurological investigation of cervical hyperaesthesia between 2009 and 2013 were retrospectively reviewed. Dogs were assigned to one of the following groups according to the final diagnosis: Non‐Neurologic, Brain, Cervical Spine, Multifocal, and Chiari‐like Malformation/Syringomyelia. Demographic data, clinical and neurological signs and laboratory findings were compared between groups using univariate analysis; predictors of disease location were assessed by multivariate analysis. Results Final diagnostic allocations of the 185 records included in the study were as follows: 2.7% Non‐Neurologic, 2.2% Brain, 63.2% Cervical Spine, 22.2% Multifocal and 9.7% Chiari Malformation/Syringomyelia. Intervertebral disc extrusion and steroid‐responsive meningitis arteritis were the most common diseases. Compared to Multifocal dogs, those allocated a Cervical Spine diagnosis were older, heavier, more frequently ataxic and lame on a thoracic limb; furthermore, they were less frequently depressed or hyperthermic at presentation. Leucocytosis, neutrophilia and monocytosis were more frequent in dogs allocated a Multifocal diagnosis. Dogs with cervical hyperaesthesia older than 36 months and non‐hyperthermic at presentation were more likely to have a lesion of the cervical region rather than a multi‐focal disease. Clinical Significance Although non‐specific, these results may be useful to guide clinicians in management of dogs presenting with cervical hyperaesthesia. Animal age and body temperature may support the suspicion of either focal or multi‐focal cervical spinal disease.

“…Hemilaminectomy could have been performed in this patient; however, the approach is technically more complex, with limited opportunity for atraumatic dissection down facial planes. Also, we and others 20 believe that visualization is inferior to that for a dorsal laminectomy in dogs. In this caudal location, the cranial aspect of the scapula can also limit access to the C7-T1 articulation when a dorsolateral approach is used in dogs.…”

“…17,18 Dorsal laminectomy was elected in this patient because osseous proliferation generally results in static compression, and direct decompression is recommended for similar lesions in dogs. 19,20 In the alpaca of the present report, dorsal laminectomy allowed the delicate debridement of proliferative new bone from the dorsolateral wall of the vertebral canal. Hemilaminectomy could have been performed in this patient; however, the approach is technically more complex, with limited opportunity for atraumatic dissection down facial planes.…”

Case Description—An 11-year-old male breeding alpaca was evaluated for a 2-day history of lowered head carriage and lethargy. Clinical Findings—On initial examination, the alpaca had signs of lethargy and lowered carriage of the head and neck, but no specific neurologic deficits. Medical management improved the clinical signs, but 8 months later, the alpaca developed acute, progressive general proprioceptive ataxia affecting all 4 limbs and was referred for further evaluation and treatment. Magnetic resonance imaging and CT identified disruption of the normal osseous architecture of C7 and T1. Medical management was attempted, but because of a lack of improvement, the patient underwent surgery 14 months after initial examination. Treatment and Outcome—A dorsal laminectomy of C7 and T1 via a dorsal midline approach was performed, and the spinous processes of both vertebrae were removed prior to removal of the overlying lamina. Free dorsal expansion of the spinal cord was ensured by resection of the ligamentum flavum. Six months after surgery, the alpaca had returned to successful breeding with 7 hembra bred in the first year after surgery, producing 6 crias, and 4 crias in the second year. The patient was eventually euthanized 28 months after surgery because of neurologic deterioration but was still ambulatory at that time. Conclusions and Clinical Relevance—A good outcome with adequate alleviation of clinical signs and breeding soundness for > 2 years following dorsal laminectomy was achieved in this camelid patient. The surgical approach was similar to that in other species and was associated with mild postoperative morbidity. Veterinarians treating camelids should be aware of the initial clinical signs and treatment options for cervical vertebral stenotic myelopathy. In acute cases, the signs of reduced cervical mobility and pain on manipulation should prompt investigation including appropriate diagnostic imaging. Timely surgical intervention should be considered in patients that respond poorly to medical treatment to avoid irreversible spinal cord injury and optimize outcome.
