radiculopathy/hypoxia

METHODS This study analyzed in vitro experiments of ectopic firing evoked by mechanical compression or hypoxia of canine lumbar dorsal roots with dorsal root ganglia using an in vitro model. OBJECTIVE The results were correlated to understand the pathophysiology of radiculopathy, which manifests

The postconcussion syndrome is a definite entity, and the patient's complaints are due to legitimate injury. The following three factors contribute to the symptomatology:1. Headaches, caused by the associated sprain of the cervical spine with resultant radiculitis-giving rise to muscle spasm and

METHODS An experimental rat study. OBJECTIVE To assess pain-related behavior and vascular endothelial growth factor (VEGF) expression induced by nucleus pulposus (NP) applied to nerve roots in rats. BACKGROUND Radiculopathy from disc herniation is caused by nerve compression and chemical

UNASSIGNED Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy of the upper extremity. It is usually associated with the compression of the median nerve in the median groove. Because the main symptoms of CTS pain and numbness worsen at night, sleep disorders in CTS patients and the

Diabetic polyneuropathy is the most frequent neuropathy in western countries. In Germany, there are 3.5 to 4 million diabetic patients. Diagnosis should rule out other polyneuropathies and assess two out of the five diagnostic criteria: neuropathic symptoms, neuropathic deficits, pathological nerve

Pathologic study of nerve tissue is especially useful for the recognition of interstitial events such as inflammation or vascular alterations that cannot be inferred from clinical or electrophysiologic findings and may provide insight into an underlying mechanism or cause. Considerable variation in

Using a novel diagnostic technology that allows to investigate the structure of a biological fluid formed during its phase transition into a dried film, we revealed a cause of mistaken results of protein concentrations in the cerebrospinal fluid of patients with discogenic radiculitis. The

OBJECTIVE Instrumentation of the osteoporotic spine may result in bone failure because of pedicle screw loosening and pullout. A clinical evaluation of a novel fenestrated bone tap used in pedicle screw augmentation was performed to determine the performance and safety of this

OBJECTIVE In this study, the authors estimate the prevalence of injuries to the soft tissue of the neck, cervical vertebrae, and cervical spinal cord among victims of abusive head trauma to better understand these injuries and their relationship to other pathophysiological findings commonly found in

Magnetic resonance (MR) imaging in patients with persistent low back pain and sciatica effectively demonstrates spine anatomy and the relationship of nerve roots and intervertebral disks. Except in cases with nerve root compression, disk extrusion, or central stenosis, conventional anatomic MR
