AANEM Connect

I did an emg on a patient that has had three thoracotomies, The last one included   and a Lat  Dorsi and serratus ant transfer. Post of pt had some scapular winging. No change  with shoulder abduction or protraction. NCS of the LTN was compared side to side. There was  a decreased amplitude of the NCS and normal latency. EMG  MUAPs showed small polyphaisc potentials,  and  reduced recruitment  or  poor activation without large MUAPs.  There were no fibs or positive waves. I thought there were a few CRDs. With the previous surgeries a dn msucle flaps , I am reluctant to call this a LT neuropathy as there is signifciant anatomical changes with the previous surgery. I  am not confident that this is a LT neuropathy. Perhaps the CRDs and small polyphasic MUAP were false postives becuase of muscle damage from the surgeries.
