sinuvertebral nerve

Nikolai Bogduk
Among other important features of the functional anatomy of the spine, described in this chapter, is the remarkable difference between the design and function of the cervical spine and that of the lumbar spine. In the cervical spine, the atlas serves to transmit the load of the head to the typical cervical vertebrae. The axis adapts the suboccipital region to the typical cervical spine. In cervical intervertebrtal discs the anulus fibrosus is not circumferential but is crescentic, and serves as an interosseous ligament in the saddle joint between vertebral bodies...

Transforaminal (TF) approach is preferred by physician to interlaminar (IL) approach because it can deliver injectates directly around nerve root and dorsal root ganglion, which is regarded as main pain sources. Axial neck pain is originated from sinuvertebral nerve located in ventral epidural spaces, which has been described to be related to central or paramedian disc herniation. It is very questionable that TF injection is also more effective than IL injection in the patients with axial neck or interscapular pain...

BACKGROUND: Patients with musculoskeletal pain (MSP) and local tenderness in the back and extremities are frequently referred to electromyography (EMG) laboratory to assess the integrity of the spinal nerve roots, peripheral nerves, and skeletal muscles. When focal muscle weakness and anatomical sensory deficits are clinically evident, this procedure is almost always abnormal. In some situations, when the presenting symptoms consist of local pain and tenderness without neuromuscular deficits, its diagnostic utility becomes questionable as illustrated in the present study...

The intervertebral discs (IVDs) are roughly cylindrical, fibrocartilaginous, articulating structures connecting the vertebral bodies, and allowing movement in the otherwise rigid anterior portion of the vertebral column. They also transfer loads and dissipate energy. Macroscopically the intervertebral disc can be divided into an outer annulus fibrosus surrounding a centrally located nucleus pulposus. The endplates surround the IVD from both the cranial and caudal ends, and separate them from the vertebral bodies and prevent the highly hydrated nucleus pulposus from bulging into the adjacent vertebrae...

Bogduk et al. (1988, Spine 13:2-8) noted that the joints and ligaments at the cervico-occipital region are susceptible to whiplash injury. The upper three cervical sinuvertebral nerves (SVNs) at the craniovertebral junction (CVJ) are thought to be responsible for mediating pain from the ligaments, dura mater, and soft tissues of the posterior cranial fossa and upper cervical column. The purpose of this study was to describe in detail the origin and course of the SVNs at C0-C1, C1-C2, and C2-C3 intervertebral levels and their anterior intraspinal distribution...

Intervertebral disc injury or degeneration is a common cause of low back pain, and yet the specific source of pain remains ambiguous in many cases. Previous research indicates that the central vertebral endplate is highly innervated and can elicit pain responses to pressure. In effort to trace the origin of nerves located at the endplate, we used protein gene product 9.5 (PGP 9.5) to stain neurofibers and then quantified the spatial pattern of nerve distribution within a human L4 lumbar vertebra. The majority of nerves were adjacent to blood vessel walls, and consequently the nerve distribution closely resembled previously established vascularity patterns...

In this exploratory study we evaluated sensitivity and target specificity of sinuvertebral nerve block (SVNB) for the diagnosis of lumbar diskogenic pain. Diskography has been the diagnostic gold standard. Fifteen patients with positive diskography underwent SVNB via interlaminar approach to the posterior aspect of the disk. Success was defined as > or = 80% pain reduction or excellent relief of physical restrictions after the block. The sensitivity was 73.3% (95% CI: 50.9%-95.7%). The target specificity was 40% (15...

Recent basic science studies on discogenic low back pain have provided new knowledge about this condition. This paper reviews some of these results and presents an overview of the following findings. The rat lumbar intervertebral disk may be innervated non-segmentally through the paravertebral sympathetic nerve and segmentally through the sinuvertebral nerves, and also by dichotomizing sensory fibers. The exposure of the nucleus pulposus (NP) to the outer annulus fibrosus (AF) may induce nerve injury and ingrowth into the disk...

The extradural supraodontoid space lies anteriorly at the craniocervical junction (CCJ) between the alar ligaments and foramen magnum. It occupies the space between the tectorial and atlanto-occipital membranes. A variety of benign and traumatic lesions may result in neurological compression here with harmful effects. Decompression by the transoral surgical approach often provides relief from these effects. Knowledge of the detailed microanatomy of this space is fragmentary. The purpose of this study was to identify the boundaries and contents of this space by microdissection...

Astronauts exposed to microgravity frequently report low back pain. This pain is described as moderate to severe in intensity. This condition warrants investigation as low back pain may hinder an astronaut's ability to perform challenging tasks by virtue of disruption of sleep and, subsequently, mental concentration. It is reported by astronauts that a "fetal tuck position" described as knees to chest position relieves back pain. It is possible that the pathogenesis of back pain in microgravity is discogenic (or mechanical) and somatic, referred from the sinuvertebral nerves due to excessive expansion of the lumbar intervertebral discs associated with reduction of gravitational compressive loads in space...

In this study we attempted to explore the correlation between lumbar disc herniation and functional disorders of the lumbar spine. Fifty patients with lumbar disc herniation proven by computed tomography underwent a comprehensive functional, neurological and radiological examination. All patients were compared to a control group consisting of 16 healthy subjects of comparable age. Only patients without signs of bone or soft tissue alterations or pregnancy at the time of examination were included into the study...

Discogenic pain has been responsible for a countless number of missed workdays and millions if not billions of dollars of lost revenue. Minimally invasive interventional therapies of the discogenic back pain gained significant acceptance among the proceduralists. The centuries old dilemma of discogenic low back pain has by no means been answered. We know today that discogenic low back pain has a multitude of causes. The leaking "chemical soup" within the nucleus pulposus is certainly responsible for causing inflammation and thus pain...

BACKGROUND: To assess whether unilateral L2 infiltration with local anesthetic can be used to identify patients who will have negative discograms and thus eliminate the need for the discogram. Discogenic low-back pain is considered to have afferent pathways in the sinuvertebral nerves, mainly originating from the ventral rami of the spinal nerves. There is evidence that pain arising from the lower lumbar intervertebral discs may be transmitted through the sympathetic afferent fibers contained in the L2 spinal nerve root...

OBJECTIVE: Our aim was to evaluate the effects of percutaneous laser disc decompression (PLDD) as discogenic pain treatment using the MacNab criteria. BACKGROUND DATA: Discogenic back pain is believed to be produced from tears in the posterior longitudinal ligament and annulus fibrosus. This pain is exacerbated through increases in intradiscal pressure via provocative discograms and transmitted through the sinuvertebral nerve. MATERIALS AND METHODS: A total of 37 patients were selected based on clinical findings and provocative discograms...

Previously, it was believed that the lumbar intervertebral disc was innervated segmentally by dorsal root ganglion (DRG) neurons via the sinuvertebral nerves. Recently, it was demonstrated using retrograde tracing methods that the lower disc (L5-L6) is innervated predominantly by upper (L1 and L2) DRG neurons via the sympathetic trunks. Furthermore, we investigated the expression of various pain-related molecules such as calcitonin gene-related peptide (CGRP), isolectin B4 (IB4), P2X(3) receptor and vanniloid receptor 1 (VR1) in DRG neurons innervating the disc using a combination of immunostaining with the retrograde tracing method...

The rat L5/6 intervertebral disc is innervated by L1 to L6 dorsal root ganglia (DRGs). T13 to L2 DRGs innervate the L5/6 intervertebral disc through paravertebral sympathetic trunks, whereas L3 to L6 DRGs directly innervate through sinuvertebral nerves on the posterior longitudinal ligament. The presence of substance P (SP)-immunoreactive (ir) and calcitonin gene-related peptide (CGRP-ir) sensory nerve fibers on the lumbar intervertebral disc has been established. SP and CGRP are markers of sensory neurons mainly involved with pain perception...

The rat L5/6 disc is innervated from T13 to L6 dorsal root ganglia (DRGs) multisegmentally. Sensory fibers from T13, L1 and L2 DRGs have been reported to innervate through the paravertebral sympathetic trunks, whereas those from L3 to L6 DRGs innervate directly through sinuvertebral nerves on the posterior longitudinal ligament (PLL). The presence of substance P (SP)- and calcitonin gene-related peptide (CGRP)-immunoreactive (ir) nerve fibers has been demonstrated in the lumbar intervertebral discs, but their percentages in DRG neurons have not been studied...

The central and lateral lumbar canals constitute complex osteofibrous neurovascular tunnels, allowing movement and deformation of the spine without loss of their main configuration. Intervertebral discs play an important role in determining their configuration. Disc degeneration may alter or even threat the functional anatomical relationships between successive adjacent "juncturae" of the vertebral column. Shape and morphometric aspects of the bony neural canals reveal level dependency [39], inter-individual variation [11], and are particularly susceptible for changes with aging [49]...
