Spinal Cord Damage (spinal + cord_damage)
Selected AbstractsImaging Spinal Cord Damage in Multiple SclerosisJOURNAL OF NEUROIMAGING, Issue 4 2005M. A. Rocca MD ABSTRACT During the past 2 decades, the considerable improvement of magnetic resonance (MR) technology and the development of new MR strategies capable of providing an in vivo overall assessment of multiple sclerosis (MS) pathology have allowed us to obtain important novel pieces of information on disease evolution in the brain. However, despite this, the correlation between brain MR imaging metrics and clinical disability are still suboptimal. A reason for this discrepancy might be the involvement of clinically eloquent structures, such as the spinal cord, which owing to technical challenges have not been extensively studied using MR imaging until very recently. An objective and accurate estimate of the presence and extent of spinal cord damage might indeed contribute to increasing the strength of the correlations between clinical and MRI metrics. This review summarizes the main results obtained from the application of conventional and modern MR-based techniques for the evaluation of spinal cord damage in MS.

Russon Summary Attempts were made to place 8-cm 22G needles into the spinal canals of four preserved cadavers using the skin entry point most commonly associated with the lateral interscalene brachial plexus block or Winnie approach (that is, at the level of the cricoid cartilage). Eleven successful attempts were confirmed by computed tomography. Needle angles that were cephalad, transverse or slightly caudad were associated with entry into the spinal canal at depths of 5.0 cm or less from the skin. The only needle entry into the spinal canal with a needle angle of > 50 degrees to the transverse plane (< 40 degrees to the sagittal plane) entered the intervertebral foramen at a depth of 7.7 cm from the skin. We conclude that the use of markedly caudad angulations of needles no longer than 5.0 cm may minimise the chances of spinal canal entry and spinal cord damage.

Konrad Cervical dystonia is the most frequent form of focal dystonia. Further, cervical dystonia can occur as a feature of segmental or generalized dystonias and cerebral palsy. Treatment with botulinum toxin to relieve pain and improve functional and psychological outcome is effective, but expensive. However, pharmacoeconomic studies evaluating treatment and disease costs have not taken into consideration the long-term complications of cervical dystonia. Here we present a review of the medical literature on orthopedic and neurological complications arising from cervical dystonia, including cervical spine degeneration, spondylosis, disk herniation, vertebral subluxations and fractures, radiculopathies and myelopathies. In summary, complications are more often reported in generalized dystonia and cerebral palsy than in focal dystonia. The prevalence is not well established, published estimations go from 18 to 41% in selected populations. Awareness of the frequent occurrence of complications and screening for symptoms of radiculomyelopathy in patients with dystonia is essential to avoid irreversible spinal cord damage. Complications of cervical dystonia need to be taken into consideration when weighting risks and calculating costs of the disease and its treatment. [source] | ||||||||||
