Spinal dural arteriovenous fistulas (SDAVFs) are the most common type of spinal arteriovenous malformations; they frequently cause progressive myelopathy, including gait disturbances and sensory disorders.We report a rare case of a middle-aged man who BACKGROUND
Cervical nerve root avulsion after trauma is a well-known occurrence. It is associated with traction injuries to the brachial plexus, commonly after high-speed motor vehicle collisions. Traumatic nerve root avulsion occurs when traction forces pull the nerve root sleeve into the
Most of the previously reported lumbosacral nerve root avulsions presented with pseudomeningoceles at the time of delayed initial imaging. We report a case of traumatic lumbosacral nerve root injury associated with an isolated femur fracture and demonstrate the evolution of pseudomeningoceles
Cervical nerve root avulsion is a well-documented result of motor vehicle collision (MVC), especially when occurring at high velocities. These avulsions are commonly traction injuries of nerve roots that may be accompanied by a tear in the meninges through the vertebral foramina with associated
METHODS
This study is to investigate the intraradicular inflammation induced by mechanical compression using in vivo model.
OBJECTIVE
The relationship between the intraradicular edema and nerve fiber degeneration induced by mechanical compression was determined in the nerve root.
BACKGROUND
Recently
METHODS
This study was aimed at investigating changes in the dorsal horn of the lumbar cord induced by mechanical compression using an in vivo model.
OBJECTIVE
To determine the effect of axonal flow disturbance in the dorsal horns induced by nerve root compression.
BACKGROUND
Few studies have looked
A 55-year-old obese man (body mass index, 31.6 kg/m(2)) presented radiating pain and motor weakness in the left leg. Magnetic resonance imaging showed an epidural mass posterior to the L5 vertebral body, which was isosignal to subcutaneous fat and it asymmetrically compressed the left side of the
Dehydration with mannitol was carried out in 58 patients suffering from grave discogenic lumbar radiculitis. A favourable effect was obtained in 43% of the cases. At the onset of the clinical manifestations of the osteochondrosis good and excellent results were obtained in 60% of the cases. As the
Prospective, cross-sectional observational study.
We aimed to investigate the effects of chronic cervical radiculopathy (CR) on the cross-sectional area (CSA) values of the cervical nerve roots (CNRs), median, ulnar, and radial nerves with high-resolution ultrasonography.
Symptomatic nerve roots are
METHODS
Edema in the dorsal nerve roots caused by acute compression was assessed quantitatively in the lumbar spine of the adult dog.
OBJECTIVE
To establish quantitative evaluation of edema in the dorsal nerve roots and to observe changes after acute compression with time.
BACKGROUND
Mechanical
OBJECTIVE
This study was designed to determine the association between LSE, spondylolisthesis, facet arthropathy, lumbar canal stenosis, BMI, radiculopathy and bone marrow edema at conventional lumbar spine MR imaging.
METHODS
This is a retrospective radiological study; 441 consecutive patients with
The anatomy and physiology of the nerve root complex in the lumbar spine are reviewed, with special reference to the effects of mechanical deformation of nerve roots in association with intervertebral disc herniation and spinal stenosis. Biomechanical aspects of nerve root deformation induced by
BACKGROUND
The main clinical symptom of lumbar spondylolysis is lower back pain. Radiculopathy rarely occurs without vertebral slippage. Hypothesis Spondylolysis in young athletes can cause lumbar radiculopathy.
METHODS
Case series; Level of evidence, 4.
METHODS
Ten patients (7 males and 3 females)
Nerve root compression has been suggested as one important pathogenetic factor in low-back pain syndromes and sciatica. The underlying pathophysiologic mechanisms are, however, incompletely known, partly because of the lack of experimental data on this topic. In the present study, a model for
BACKGROUND
Routine lumbar spine magnetic resonance imaging (MRI) may not show any evidence of the cause of sciatica in some cases. The relationship between nerve root compression detected on lumbar MRI and sciatica is also sometimes uncertain.
OBJECTIVE
To ascertain whether axial (and, when
