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

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

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

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
