Abstract

The accessory nerve is the eleventh cranial nerve that supplies the sternocleidomastoid
and trapezius muscles. Injury to the spinal accessory nerve is most commonly caused
by medical procedures that involve the head and neck, which causes wasting of the
shoulder muscles, winging of the scapula, and weakness of shoulder abduction and
external rotation. Here, two cases of spinal accessory neuropathy after injection of
trapezius muscle for body building are reported.
