“…The most common causes of spinal cord infarction in adults are vascular, including atherosclerosis, abdominal aortic disease/ surgery, and hypotension [6,[12][13][14][15][16][17]. Compromise of blood flow to the adult cord has also been associated with cervical spondylosis [18]. With the exception of hypotension, these are diseases that take years to develop.…”

Spinal cord infarction in children is a rare condition which is becoming more widely recognized. There are few reports in the pediatric literature characterizing etiology, diagnosis, treament and prognosis. The risk factors for pediatric ischemic spinal cord infarction include obstruction of blood flow associated with cardiovascular compromise or malformation, iatrogenic or traumatic vascular inujury, cerebellar herniation, thrombotic or embolic disease, infection, and vasculitis. In many children the cause of spinal cord ischemia in the absence of vertebral fracture is unknown. Imaging diagnosis of spinal cord ischemia is often difficult due to the small transverse area of the cord, cerebrospinal fluid artifact and inadequate resolution of MRI. Physical therapy is the most important treatment option. The prognosis is dependent on the level of spinal cord damage, early identification and reversal of ischemia, and follow-up with intensive physical therapy and medical support. In addition to summarizing the literature regarding spinal cord infarction in children without vertebral fracture, this review article adds two cases to the literature which highlight the difficulties and controversies in the management of this condition.

“…The degeneration of the intervertebral disc and secondary degeneration of stable structures such as the uncovertebral joint, facet joint, posterior longitudinal ligament, and ligamentum flavum cause spinal cord compression and cervical myelopathy [1]. The presence of degenerative changes is very common in the general population and becomes more common with increasing age [2][3][4]. Individuals with congenital cervical canal stenosis are more vulnerable to cervical myelopathy caused by cervical degeneration and spinal cord compression [1][2][3][4].…”

Anterior approach versus posterior approach for the treatment of multilevel cervical spondylotic myelopathy: a systemic review and meta-analysis

et al. 2013

Purpose To compare the clinical outcomes, complications, and surgical trauma between anterior and posterior approaches for the treatment of multilevel cervical spondylotic myelopathy. Study design Systematic review and meta-analysis. Methods We searched MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials databases for randomized controlled trials or non-randomized controlled trials that compared anterior and posterior surgical approaches for the treatment of multilevel cervical spondylotic myelopathy. Exclusion criteria were non-controlled studies, combined anterior and posterior surgery, follow-up \1 year, cervical kyphosis [15°, and cervical myelopathy caused by ossification of the posterior longitudinal ligament. The main end points included: recovery rate; Japanese Orthopedic Association (JOA) score; reoperation rate; complication rate; blood loss; and operation time. Subgroup analysis was conducted according to the mean number of surgical segments. Result A total of eight studies were included in the metaanalysis; none of which were randomized controlled trials. All of the selected studies were of high quality as indicated by the Newcastle-Ottawa scale. In five studies involving 351 patients, the preoperative JOA score was similar between the anterior and posterior groups [P [ 0.05, WMD: -0.00 (-0.56, 0.56)]. In four studies involving 268 patients, the postoperative JOA score was higher in the anterior group compared with the posterior group [P \ 0.05, WMD: 0.79 (0.16, 1.42)]. For recovery rate, there was significant heterogeneity among the four studies involving 304 patients, hence, only descriptive analysis was performed. In seven studies involving 447 patients, the postoperative complication rate was significant higher in the anterior group compared with the posterior group [P \ 0.05, odds ratio: 2.60 (1.63, 4.15)]. Of the 245 patients in the 8 studies who received anterior surgery, 21 (8.57 %) received reoperation. Of the 285 patients who received posterior surgery, only 1 (0.3 %) received reoperation. The reoperation rate was significantly higher in the anterior group compared with the posterior group (P \ 0.001). In the 3 studies involving 236 patients compared subtotal corpectomy and laminoplasty/laminectomy, blood loss and operation time were significantly higher in the anterior subtotal corpectomy group compared with the posterior laminoplasty/laminectomy group [P \ 0.05, WMD: 150.10 (63.53, 236.66) and P \ 0.05, WMD: 59.17 (45.69, 72.66)]. Conclusion The anterior approach was associated with better postoperative neural function than the posterior approach in the treatment of multilevel cervical spondylotic myelopathy. There was no apparent difference in the neural function recovery rate. The complication and reoperation rates were significantly higher in the anterior group compared with the posterior group. The surgical trauma associated with corpectomy was significantly higher than that associated with laminoplasty/laminectomy.

Relative vulnerability of various spinal tracts in C3-4 cervical spondylotic myelopathy: multi-modal spinal cord evoked potentials

et al. 2011

View full text Add to dashboard Cite

Methods: A total of 30 patients with CSM were investigated in this study. In all patients, only the C3-4 intervertebral level was symptomatic, as shown by examination of SCEPs. SCEPs were recorded following median nerve stimulation (MN-SCEPs), transcranial electric stimulation (TES-SCEPs) and spinal cord stimulation (spinal-SCEPs). Results: The incidence of abnormalities varied in the order of MN-SCEPs (100%), TES-SCEPs (90%) and spinal-SCEPs (67%). Patients were grouped into three types according to SCEPs: transverse (all SCEPs abnormal), post-erolateral (abnormalities in the MN-SCEPs and TES-SCEPs) and upper limbs sensory (abnormal only for MN-SCEPs). In all, 20 of the 30 patients (67%) were the transverse type, 7 (23%) the post-erolateral type and 3 (10%) the upper limbs sensory type. Conclusion: The present study showed the lateral part of the posterior funiculus mediating upper limb sensory function was more vulnerable than the lateral corticospinal tract, which is consistent with numbness tending to appear at an early stage of mild CSM.
