BACKGROUND When spinal fusion is applied to degenerative lumbar spinal disease with instability, adjacent segment disorder will be an issue in the future. However, decompression alone could cause recurrence of spinal canal stenosis because of increased instability on operated segments and lead to revision surgery. Covering the disadvantages of both procedures, we applied nonfusion stabilization...
A recent study reported remarkable survival and exuberant axon outgrowth from transplants of neural stem cells (NSCs) in a fibrin matrix with growth factors that were grafted into a complete spinal cord transection site in rats (Lu et al., 2012). As part of the NIH-supported replication project (Facilities of Research Excellence-Spinal Cord Injury), we repeated key parts of that study. Because ...
Cannabinoids are involved in the regulation of neural stem cell biology and their receptors are expressed in the neurogenic niches of adult rodents. In the spinal cord of rats and mice, neural stem cells can be found in the ependymal region, surrounding the central canal, but there is evidence that this region is largely different in adult humans: lacks a patent canal and presents perivascular ...
A spinal neurofibroma with malignant change leading to `sarcomatous meningitis' is described in a woman of 73. Three similar cases have been found in the literature. This is an exceedingly rare complication of nerve sheath tumours in the spinal canal.
STUDY DESIGN Retrospective case series. PURPOSE The purpose of this study was to examine changes in the ligamentum flavum thickness and remodeling of the spinal canal after anterior fusion during a 10-year follow-up. OVERVIEW OF LITERATURE Extreme lateral interbody fusion provides minimally invasive treatment of the lumbar spine; this anterior fusion without direct posterior decompression, ...
OBJECTIVE To evaluate the effectiveness of the In- space (Synthes, Umkirch, Germany) and the correlation between radiographic parameters and clinical outcome in patients with lumbar spinal canal stenosis (LSS). METHODS Between June 2009 and May 2013, 56 patients with LSS underwent In-space by one senior surgeon. All of the patients were evaluated both clinically and radiographic measurements ...
Over 90 years ago, Kolmer and Agduhr identified spinal cerebrospinal fluid-contacting neurons (CSF-cNs) based on their morphology and location within the spinal cord. In more than 200 vertebrate species, they observed ciliated neurons around the central canal that extended a brush of microvilli into the cerebrospinal fluid (CSF). Although their morphology is suggestive of a primitive sensory ce...
explain the pathophysiology of syringomyelia associated with the Chiari I malformation. In some of them, mechanisms in which the syrinx expands progressively from an initially small locus of syringomyelia, a “drop” of fluid, to a cavity that is large enough to distend the spinal cord are proposed. This is the mechanism proposed for the theories advocated by Gardner and Angel,4,5 and Williams18–...
