Question: PIN Palsy

 MrMech - Fri Feb 09, 2007 11:03 am

I have had complications following distal biceps tendon surgery. I have PIN nerve damage. The EMG disclosed mild to moderate number of sharp waves and fibrillation potential in right extensor radialis longus and extensor indicis proprius muscle. The Neurologist concluded that I had neuropathy with partial axonal loss.He said there was presence of reinervation in the extensor carpi radialis muscle and that this proves the nerve is not severed. I read that this particular muscle was controlled by the main branch of the radial nerve not the PIN, am I correct?. Do waves and fibrillations mean a good prognosis? Are EMGs very accurate? There was also no motor action potentials in nerve conduction studies in the extensor indicis proprius muscle.
Thank you,
Mike T

User avatar I can't answer all of your questions as this is not my specialty. However, there are a few I can answer.

Fasciculations often indicate lower nerve damage (nerves beyond the spinal cord). They can also arise with healing nerves.

EMG's are very accurate. They are the best method of nerve/muscle evaluation we have at this point, to my knowledge.

Nerve regeneration is a slow process. Physical therapy can help with this.

Sorry I'm not able to answer your other more specific questions.

Best wishes.

Hi I am now 4 months plus 2 week post op, radial nerve palsy following distal bicep repair.. I have regained mostly all my hand functions, I would say 70%. 1 month ago I barely moved my fingers and my thumb was not moving. I have been taking a Vitamin B-12 5000mg 3x a week with methylcobalamin and a regular mutli with a B-100 complex, daily. I am recovering rapidly. My point is that i would feel negligent if i did not post that there is info on the web about B-12 and it's benefits to nerves, and that my EMG was very negative 2 months ago so it's not always 100%. My neurologist painted me a bleak picture. He was wrong I am happy to report. On another note I also work out 3 days a week and rom exercises daily. And wear my brace to bed to stabilize my arm at night.
Thanks for the advice.And speedy revovery to anyone hurting out there.
