neuro25SCI syndromes

QuestionAnswer
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.
