When a patient abducts an arm and the ipsilateral scapula becomes more prominent (winged), this usually means that:
a. there has been an injury to the nerve of the anterior serratus muscle.
b. one of the clavicles has been fractured.
c. there is a unilateral trapezius muscle se-paration.
d. one shoulder is dislocated.
A
If the long thoracic nerve is damaged or bruised, it can cause paralysis of the serratus anterior muscle and winging of the scapula, or shoulder blade. This is not a symptom of a fractured cla-vicle or trapezius muscle separation. A dislocated shoulder would result in a hollowing effect.
