Also known as transient brachial plexus neuropraxia, “dead arm syndrome,” or brachial plexopathy. Symptoms such as pain, burning, and/or paresthesias in a single upper limb, lasting seconds to minutes.
Usually involves more than one dermatome
May be associated with weakness.
-Common in collision sports that involve tackling, such as football.
-Most common C-spine injury in American Football.
-More than 50% of college football players sustain a stinger each year
-Having 1 stinger increases the risk of having another 3 fold
Mechansims: C5, C6 (deltoid,biceps) most commonly involved
-Traction injury due to forcible lateral neck flexion away with downward displacement of arm
-Nerve root compression during combined neck extension and lateral neck flexion
-Direct trauma to the brachial plexus in the supraclavicular fossa
Physical Exam:
-Examine muscle strength in the deltoid, biceps, and infraspinatus muscles
-Check sensation and reflexes in upper extremities
-Check C-spine range of motion and perform Spurling’s Test
Imaging:
Consider MRI for symptoms lasting more than 24 hours, bilateral symptoms or for recurrent stingers
Return to play guidelines vary:
-No neurologic symptoms
-Can return to play in same game if symptoms resolve within 15 minutes and no prior stingers that season.
-If 2nd stinger in that season, do NOT return to play in the same game
-if 3rd stinger in a season, consider imaging before return to play and consider sitting out the remainder of the season.
