neuro25SCI syndromes
Question | Answer |
---|---|
Anterior Cord Syndrome | An incomplete lesion that results from compression and damage to the anterior part of the spinal cord or anterior spinal artery. |
The mechanism of injury Anterior Cord Syndrome | is usually cervical flexion. |
Anterior Cord Syndrome There is loss of | motor function and pain and temperature sense below the lesion due to damage of the corticospinal and spinothalamic tracts. |
Brown-Sequard's Syndrome | An incomplete lesion usually caused by a stab wound, which produces hemisection of the spinal cord. |
Brown-Sequard's Syndrome There is | paralysis and loss of vibratory and position sense on the same side as the lesion due to the damage to the corticospinal tract and dorsal columns. |
Brown-Sequard's Syndrome There is a loss of | pain and temperature sense on the opposite side of the lesion from damage to the lateral spinothalamic tract. |
Pure Brown-Sequardʼs syndrome is | rare since most spinal cord lesions are atypical. |
Cauda Equina Injuries An injury that occurs below the | L1 spinal level where the long nerve roots transcend. Cauda equina injuries can be complete, however, they are frequently incomplete due to the large number of nerve roots in the area. |
A cauda equina injury is considered a . | peripheral nerve injury |
Characteristics Cauda Equina Injuries include | flaccidity, areflexia, and impairment of bowel and bladder function. Full recovery is not typical due to the distance needed for axonal regeneration. |
Central Cord Syndrome An | incomplete lesion that results from compression and damage to the central portion of the spinal cord. |
The mechanism of injury Central Cord Syndrome is usually | cervical hyperextension that damages the spinothalamic tract, corticospinal tract, and dorsal columns. |
Central Cord Syndrome | The upper extremities present with greater involvement than the lower extremities and greater motor deficits exist as compared to sensory deficits. |
Posterior Cord Syndrome | A relatively rare syndrome that is caused by compression of the posterior spinal artery and is characterized by loss of pain perception, proprioception, two-point discrimination, and stereognosis. |
Posterior Cord Syndrome | Motor function is preserved. |
