<span style="font-size:16px;"><strong>Stingers and Burners</strong></span></p>
<p>
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.</p>
<p>
Usually involves more than one dermatome</p>
<p>
May be associated with weakness.</p>
<p>
-Common in collision sports that involve tackling, such as football.</p>
<p>
-Most common C-spine injury in American Football. </p>
<p>
-More than 50% of college football players sustain a stinger each year</p>
<p>
-Having 1 stinger increases the risk of having another 3 fold</p>
<p>
<strong>Mechansims</strong>: C5, C6 (deltoid,biceps) most commonly involved</p>
<p>
-Traction injury due to forcible lateral neck flexion away with downward displacement of arm</p>
<p>
-Nerve root compression during combined neck extension and lateral neck flexion</p>
<p>
-Direct trauma to the brachial plexus in the supraclavicular fossa</p>
<p>
<strong>Physical Exam</strong>:</p>
<p>
-Examine muscle strength in the deltoid, biceps, and infraspinatus muscles</p>
<p>
-Check sensation and reflexes in upper extremities</p>
<p>
-Check C-spine range of motion and perform Spurling’s Test</p>
<p>
<strong>Imaging:</strong></p>
<p>
Consider MRI for symptoms lasting more than 24 hours, bilateral symptoms or for recurrent stingers</p>
<p>
<strong>Return to play guidelines vary</strong>:</p>
<p>
-No neurologic symptoms</p>
<p>
-Can return to play in same game if symptoms resolve within 15 minutes and no prior stingers that season.</p>
<p>
-If 2<sup>nd</sup> stinger in that season, do NOT return to play in the same game</p>
<p>
-if 3<sup>rd</sup> stinger in a season, consider imaging before return to play and consider sitting out the remainder of the season.</p>
