Sheaths of the spinal nerve roots

Acta Neuropathologica, 1993
The present study was carried out to investigate the permeability of normal spinal nerve root sheaths around dorsal and ventral roots in the rat. In vivo studies were performed using Evans blue-albumin and lanthanum chloride as tracers. The Evans blue-albumin complex is macromolecular in size and lanthanum ions are small and easily visible in the ...

Connection types between the spinal root of the accessory nerve and the posterior roots of the C2–C6 spinal nerves

open access: yesSurgical and Radiologic Anatomy, 2009
The aim of this study was to demonstrate the connection types and frequency between the accessory nerve and the posterior roots of the C2-C6 cervical nerves.The cranial cervical regions of 49 specimens from 27 human cadavers were used for the present study under an operating microscope.Five different connection types between the accessory nerve and the

Spinal Nerve Root Compression

Spine, 1995
The pathophysiology of sciatica is not completely understood, although our understanding of its causes is increasing. Mechanical alterations combined with inflammatory changes lead to pain. Compression alters nerve root conduction and compromises the nutritional support of spinal nerve roots (through intrinsic and extrinsic vascularity and cerebral ...

Hemangioma of spinal nerve root

Journal of Neurosurgery: Spine, 1999
Object. Hemangiomas of the spinal nerve roots are rare. Only 12 cases have been reported in the literature, all since 1965. These lesions occurred in adults, primarily in males, and were located in the cauda equina. Of the 12 lesions, eight were cavernous hemangiomas. The authors report here the clinicopathological features of 10 cases of hemangioma of

Ependymoma of the Spinal Nerve Root

Neurosurgery, 1992
Ependymomas are the most common intramedullary tumor of the spinal cord. They are most common at the region of the cauda equina, accounting for up to 90% of primary tumors in that area. Extraspinal ependymomas are rare. We describe a case of an ependymoma arising in a spinal peripheral nerve root.

Multiple neurofibromas of the spinal nerve roots

Journal of Clinical Neuroscience, 1995
This report describes a rare case of a suspected neurofibromatosis type 1 patient who had multiple bilateral spinal neurofibromas from the cervical to the sacral spinal dorsal nerve roots. The lesions were readily detected by MR imaging and the largest tumour was successfully resected.

Spinal Nerve Root Stimulation

2011
Spinal nerve root stimulation (SNRS) is a neuromodulation technique that is used to treat chronic pain. This modality places stimulator electrode array(s) along the spinal nerve roots, creating stimulation paresthesias within the distribution of the target nerve root(s), thereby treating pain in that same distribution. There are several different forms
