SummaryThree middle-aged (6-8 years), intact male Dachshunds were admitted to the University of Tennessee Veterinary Teaching Hospital (UTVTH) with acute onset of back pain and pelvic limb paralysis.Physical examination of dog #1 revealed hyperaesthesia of the thoracolumbar spine. Superficial pain sensation was absent in the pelvic limbs, while deep pain sensation was intact. The cutaneous trunci (panniculus) reflex was absent caudal to the thoraco-lumbar region. Reflexes to the pelvic limbs were exaggerated.A myelogram showed dorsal deviation of the ventral contrast column and attenuation of the ventral and dorsal contrast columns at the T9-T10 disc space. A hemilaminectomy was performed from T9 to T10, and mineralized disc material was retrieved from the vertebral canal at T9-T10. The T9- T10 to L3-L4 disc spaces were fenestrated. Two weeks after surgery, superficial and deep pain sensation of the rearlimbs were present, but paralysis persisted. The animal was euthanatised at the owners’ request. A postmortem examination was not performed.Dog #2 displayed absent superficial pain sensation, and intact deep pain sensation of the pelvic limbs. Hyperaesthesia of the thoracolumbar region and hyperreflexia of the rear limbs were noted. Examination of the cutaneous trunci reflex was not performed. A myelogram revealed ventral extradural compression of the spinal cord at T9- T10. A T9-T10 hemilaminectomy revealed a large amount of extruded disc material, which was removed. The Tll- T12 to L4-L5 intervertebral discs were fenestrated. Forty-eight hours postoperatively, the patient regained voluntary motor function, and recovery was uneventful.Neurologic examination of dog #3 revealed absence of deep pain sensation in the pelvic limbs; duration of which was not known. Spinal radiographs and myelography revealed ventral extradural spinal cord compression at T9-T10 (Fig.). A right-sided hemilaminectomy at T9-T10 revealed a large amount of calcified disc material, ventral to the spinal cord. The T11-T12 through Ll- L2 intervertebral discs were fenestrated. Sixty days postoperatively, paralysis persisted and the dog was euthanatised. No postmortem examination was performed.Herniation of the T9-T10 intervertebral disc was diagnosed in three Dachshunds with acute paraplegia. The clinical diagnosis and surgical management of T9-T10 disc herniation are similar to that in the more common sites of disc herniation.

Zidan N, Medland J, Olby NJ. Long-term postoperative pain evaluation in dogs with thoracolumbar intervertebral disc herniation after hemilaminectomy. J Vet Intern Med 2020. doi: 10.1111/jvim.15800. Beim Menschen ist chronischer neuropathischer Schmerz eine häufige Komplikation nach Rückenmarksinsulten, ca. 50–80 % der Patienten entwickeln eine derartige Dolenz. Für den Hund liegen diesbezüglich keine Studiendaten vor, vor allem aufgrund der herausfordernden Evaluierung insbesondere von neuropathischen Schmerzzuständen. Diese Studie prüfte die Verlässlichkeit einer Messung von spinalen mechanisch ausgelösten sensorischen Schwellenwerten (mechanical sensory threshholds, MSTs) und verglich die MSTs gesunder Hunde mit denen von Hunden nach operativer Hemilaminektomie aufgrund einer thorakolumbaren intervertebralen Diskherniation (IVDH).

Abstract Thoracolumbar intervertebral disc herniation is a common neurologic disease presented to the small-animal practitioner. The use of methylprednisolone sodium succinate (MPSS) as an adjunct to surgical decompression in cases of acute spinal cord injury following intervertebral disc extrusion is controversial. A prospective study was undertaken to compare the preoperative use of MPSS and non-steroidal anti-inflammatory drugs (NSAIDs) in 40 chondrodystrophic dogs presenting with similar signs and undergoing spinal decompressive surgery. Twenty dogs received MPSS and 20 had NSAIDs administered preoperatively. Dogs were administered with either MPSS intravenously 20 minutes before surgery (30 mg/kg) or NSAID (meloxicam 0.2mg/kg or carprofen 4 mg/kg) subcutaneously 20 minutes before surgery. Dogs were evaluated by neurologic examination of gait 24 hours postoperatively, at time of discharge and then at 8 weeks. The neurological recovery were similar in both groups, but the frequency of side effects such as vomiting (MPSS group: 90% versus NSAIDs group: 55%), and anorexia within the first three days (present in all 20 dogs pretreated with MPSS) was significantly different, with complications being more prevalent in the MPSS group. Side effects were significantly more evident with MPSS treatment group –including vomiting and anorexia during the first 3 days after surgery– than with NSAID treatment group, with a neurological recovery similar in both groups.
