Specific Incomplete lesions

Question 1

Anterior Cord Syndrome

Answer 1

An incomplete lesion that results from the compression and damage to the ant part of the spinal cord and/or spinal artery. The mechanism is usually cervical flexion. There is a los of motor function and pain and temp sense below the lesion to damage to the corticospinal and spiunothalamic tracts

Question 2

Brown Sequard Syndrome

Answer 2

An incomplete lesion usually caused by a stab wound, which produces hemisection of the spinal cord. There is paralysis and loss of vibratory and position sense on the same side as lesion due to the damage to the corticospinal tract and dorsal columns. There is loss of pain and temp on contra later side from spinothalamic.

Question 3

Cauda Equina Injuries

Answer 3

An injury that occur below the L1 spinal level where the long nerve roots transcend. Can be complete but usually incomplete due to numerous nerves. Considered peripheral nerve injury. Characteristics include flaccidity, areflexia, and impairments of bowel and bladder function. Full recovery is not typical due to the distance needed for axonal regeneration.

Question 4

Central Cord Syndrome

Answer 4

An incomplete lesion that results from compression and damage to the central portion of the spinal cord. Mechanism usually cervical hyperextension that damages the spinothalamic, corticospinal and dorsal columns, the Ue presents w the greater involvement than LE and greater motor effects than sensory.

Question 5

Posterior Cord syndrome

Answer 5

A relatively rare syndrome that is caused by the compression of the spinal artery and is characterized by the loss of pain perception, proprioception, 2 pt disc, and stereognosis. Motor function is preserved.
