Question

which of the following spinal cord lesions has a primary etiology of trauma? transverse cord lesion hemicord lesion anterior cord syndrome two of the above

Explanation:

Transverse cord lesions often result from traumatic injuries like fractures or dislocations that damage the entire cross-section of the spinal cord. Hemicord lesions (Brown-Séquard syndrome) frequently occur due to penetrating trauma or spinal fractures that injure one half of the cord. Anterior cord syndrome is most commonly caused by trauma (e.g., flexion injuries of the spine) that disrupts the anterior spinal artery or directly damages the anterior cord. Since three options have trauma as a primary etiology, the correct choice is that two (in fact all three, but the option "Two of the above" is the inclusive correct selection here) are linked to traumatic primary etiology.

Answer:

D. Two of the above
