Could pectoral implant cause loss of muscle function?
I had Pectoral implants 5 months ago and since then I have lost the ability to extend my fingers. This is only in my right hand and the implant on that side is sitting at a slight angle and is protruding more towards my armpit than on the left side. I have read that the extensor muscles for your hand are actually in your forearm. This is why I am suspecting a nerve impingement from the implant vs. carpal tunnel.
The extension of fingers is a function of the radial nerve. Although your implant may seem to protrude into the armpit area the nerves that provide control of your arm come from the neck. This should be actually very far from your implant and not playing a role in these symptoms.
