Lumbosacral transitional vertebrae and nerve-root symptoms.
Transitional vertebrae (TV) may be one of the risk factors for lumbar disc herniation. It is not clear, however, whether the presence of TV can affect the development of nerve-root symptoms. Our aim was to clarify this relationship. A total of 501 patients with lumbar degenerative disease and nerve-root symptoms was studied in respect of their level and the presence of TV. As a control group, 5...
متن کاملConjoint Lumbosacral Nerve Root-A Case Report
INTRODUCTION Conjoint nerve root is embryological nerve root anomaly mainly involving lumbosacral region. The anomalous roots present primarily as a bifid, conjoined structure arising from a wide area of the dura. Because of their size and attachment to surrounding structures, they are uniquely susceptible to trauma. The effects of compression and entrapment are amplified in the presence of ste...
متن کاملLumbosacral plexus lesions: correlation of clinical signs and computed tomography.
Neurological signs and computed tomographic morphology were compared in 60 patients. The primary neurological deficit was most commonly located in the sacral (n = 31) or lumbar plexus (n = 23) and was most commonly caused by a neoplasm (n = 40). In 78% of the patients it correlated with the lesions detected by computed tomography (CT). CT reliably demonstrates extraspinal mass lesions, but only...
متن کاملCT morphology of intrathecal lumbosacral nerve-root compression.
Spinal CT scans and radiculograms of 100 patients who had undergone both examinations were studied with the aim of identifying morphologic CT features associated with compression of the intrathecal segment of the nerve root as demonstrated by radiculography. The interest for such a study lies in the fact that, in contradistinction to the distal, extrathecal root segment outlined by fat in the f...
متن کاملLumbosacral nerve root avulsions: MR imaging demonstration of acute abnormalities.
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 following nerve root avulsions and edema in the perineural fat identified on the initial MR imaging.
