Spinal Cord Dysfunction

SummaryObjective: To identify the severity of neurological deficits, presence of signs of cervical pain, and the site of intervertebral disc space extrusion in 21 dogs diagnosed via magnetic resonance imaging (MRI) with a hydrated nucleus pulposus extrusion (HNPE) and compare those findings to dogs with other compressive cervical myelopathies.Methods: Medical records and MRI findings were reviewed in dogs that were presented to two veterinary hospitals between 2006 and 2012 and subsequently diagnosed by MRI to have a HNPE (n = 21) or other compressive cervical myelopathies originating from the intervertebral disc (n = 174). Information obtained included signalment, severity of neurological deficits, presence of signs of neck pain, and site of HNPE. The severity of clinical neurological spinal cord dysfunction was determined for each dog in both groups using the Frankel scoring system (0–4). The MRI were reviewed for confirmation of diagnosis and site of HNPE. An ANOVA was used to compare age between groups and a Mann-Whitney test for pairwise comparisons of the Frankel score between groups. Values of p <0.05 were considered statistically significant.Results: Significantly more severe Frankel scores and less severe signs of cervical pain detected on palpation were observed in dogs with a HNPE as compared to dogs with other compressive myelopathies. The sites of HNPE were C3-C4 (8/21), C4-C5 (12/21), and C5-C6 (1/21).Clinical significance: Dogs affected with HNPE have more severe clinical neurological deficits and less severe signs of cervical pain as compared to dogs with other compressive cervical myelopathies.

Introduction. Spinal mobile tumors are very rare. We herein report a case of paraplegia caused by migration and incarceration of thoracic mobile schwannoma after myelography. Case Presentation. A 25-year-old man who had weakness and numbness in both his legs also had pain radiating to the back that was induced by back flexion or extension and jumping. Magnetic resonance imaging (MRI) showed an intradural extramedullary lesion at the T10 and T11 levels. Myelography was performed but discontinued due to his back and lower limb pain. Computed tomography after myelography revealed a rostrally migrated intradural mass with a discrepancy in the exact location in comparison to the MRI findings. He underwent a second lumbar puncture and drained the cerebrospinal fluid (CSF) to aid the spinal cord, because the symptoms gradually worsened and led to paraplegia. After the drainage of the CSF, his symptoms were immediately resolved. The day after myelography, he underwent complete resection of the tumor with the diagnosis of schwannoma. One year after the surgery, he had been working despite having hyperreflexia in his lower limbs with no weakness or sensory disturbance. Conclusion. Severe neurological deficits associated with spinal cord damage can occur due to migration of mobile tumors.

The case report demonstrates the issue of Khalid Ali, who is a citizen of Yamen, explicitly living in Saudi Arabia. He is 38 years, weighs 82kgs, and of 162 cm in height. He is a sales professional and married with two kids. Khalid Ali has been living healthy until two years ago when he started experiencing pains in his lower extremities accompanied by numbness. He was treated, and everything went back to normal until soon when the case came back after the administration of the Pfizer vaccine as a preventive measure for COVID-19 disease. The consequence of the administration of the Pfizer vaccine resulted in severe pain and weaknesses in his legs and severe headache on the second day, which resulted in him being put on an ICU after 48 hours since he was almost paralyzed. A series of tests were conducted on him, including magnetic resonance imaging (MRI), hematology, and biochemistry which involved Cerebrospinal Fluid (CSF) protein test. MRI findings were significant since they indicated acute inflammation on the spine observed on the dorsal spinal cord with contrast and lumbosacral spinal cord. All the hematology tests turned out to be expected. Biochemistry conducted tests were similarly standard except for CSF protein which was highly abnormal. The combination of the high abnormal CSF protein test and acute inflammation of the spine observed from the MRI findings were confirmed evidence of acute transverse myelitis as a result of the administration of the Pfizer vaccine.

Intervertebral Disc Height

Interbody fusion is a well-recognized technique to achieve spinal fusion. The advantage of using tricortical blocks as opposed to the dowel technique is that intervertebral disc height can be restored. Both techniques can be performed either by the anterior or posterior approach. The traditional tricortical block technique has advantages over using dowels as it is a more stable construct and can restore intervertebral disc height. However, autologous bone graft has an unpredictable behavior causing potential problems of disc space collapse, forward displacement of the graft and donor bone graft site morbidity. The Hartshill horseshoe was developed to overcome these autograft problems. It is an implant that is placed within the periphery of the intervertebral disc space where the vertebral end plate is strongest to resist compression forces. It has holes that allow screw fixation of the implant to bone to provide immediate stability and a central area for bone graft where the vertebral body is most vascular to allow incorporation of such a graft. Previous reports on the Hartshill horseshoe have used autograft (single tricortical graft). This prospective study reports the clinical and radiological results of 19 patients who underwent this procedure using xenograft 2½ to 3 years postoperative. The radiological results do not show any evidence of loosening of the screws or implant nor evidence of intervertebral disc space subsidence. It was not possible to assess the exact incidence of spinal fusion.

Favourable Prognosis

SummaryThoracolumbar intervertebral disc disease is the most common cause of caudal paresis in dogs (1). Whilst the pathogenesis of the extrusion has been widely studied, treatment protocols and prognostic factors relating to outcome remain controversial. Recent studies have examined a multitude of factors relating to time to regain ambulation after decompressive surgery. Most intervertebral disc herniations occur in the thoracolumbar region, causing upper motor neuron signs in the rear limbs, which are thought to have a more favourable prognosis compared to the lower motor neuron signs created by herniation of an intervertebral disc in the caudal lumbar region. Due to the potential disruption of the lumbar intumescence, lower motor neuron signs have been reported as having a less favourable prognosis. The purpose of this study was to evaluate the intervertebral disc space as a prognostic factor relating to ambulatory outcome and time to ambulation after decompressive surgery. Hansen Type I intervertebral disc extrusions were studied in 308 non-ambulatory dogs. Preoperative and postoperative neurological status, corticosteroid use, signalment, intervertebral disc space, postoperative physical rehabilitation, previous hemilaminectomy surgery, disc fenestration, return to ambulation, and time to ambulation were reviewed.
