Peroneal neuropathy at the fibular head.

Hey all, I have had an update on my mri spine test and EMG nerve conduction test, everything is normal on my mri which is brilliant news. I am a little confused with the emg results though. Could anyone be able to explain what this means please or just some advice. The consultant clinical neurophysiologist notes there are some features suggestive of a right sided Common peroneal neuropathy at the fibular head, the basis of this was that the motor responses were within normal amplitude when performed distally but promiximally they were a little reduced. The rest of the study was within normal limits with no evidence of a generalised polyneuropathy, no evidence of active denervation changes in any of the muscles tested.given that the clinical examination was within normal limits this is an incidental finding but certainly we can discuss at the point of follow up. I know this isn’t a Ms post but I was wondering if anyone has been through similar? I can probably rule out Ms now with all the findings.

Hi, I think your Neuro/Doctor would explain this better, but I found this on-line which might help.

Common peroneal neuropathy , also known as fibular neuropathy is a nerve compression syndrome of the common peroneal nerve (CPN) at the level of the fibular head. It is the most common cause of spontaneous painless unilateral foot drop.

Thank you for sharing that information and your help, it was interesting to read. I will have a follow up with my neurologist and go from there. I am just concerned if it’s connected to my dad’s diagnosis, he had a blood clot (dvt) behind his right knee but that’s a different topic. Thank you again.
