PT student looking for an answer to a question posed by my CI. Question, what is th most common occupational cause of injury to Long thoracic nerve resulting in weakness in serratu anterior.
I understand the mechanisms of injury being a direst blow, traction, compression against chest wall, Heavy above shoulder effort, Repetitive strain.
\
My guess is it fall in the repetitive strain area, however, I really have not experienced any patients with this condition. None of my text gives much insight (that I can find) into this work related injury. She says she has a good book that lists common sources of injury such as this.
Any Ideas would be helpful so I could give her a response hopfully this week. This is really bugging me to find the answer.

Hmmm....can't remember the MOST common, but professional football players and motocross racers have a relatively high incidence of transient serratus weakness due to injury to this nerve -- I believe it is often caused by massive force applied directly along the axis of the extended arm while the shoulder is flexed to 90, but in a manner where the impulse is great and the scapular musculature has limited time -- or actually no reaction time -- to modulate the force, as in a motorcycle accident or getting tackled from behind while you're trying to push someone else.
Hmmm...occupational...maybe someone who operates a jackhammer?

Carrying the heavy object on the shoulder for a long time(e.g.,a steel beam) may compress this nerve between the clavicle and the lateral part of the first rib. From:Keith L.Moore Clinically Oriented Anatomy 3rd ed.
