VSR-0152
QUESTION
For confirmatory diagnosis of navicular disease the nerve block is used?
OPTIONS
(A) Median
(B) Posterior digital
(C) Volar
(D) Ulnar
ANSWER
(B) Posterior digital
EXPLANATION
Blocking the palmar digital nerves, also called posterior digital nerves, can help localize pain to the caudal foot and is used in evaluation of navicular-region pain. Median and ulnar nerve blocks are more proximal, while 'volar' is a broad positional term rather than the named bilateral distal digital block.
