Hi Steve

I’ve also seen EPL dysfunction and rupture with long volar plate screws however the EPL was intact with no collagen changes at Listers tubercle.
The swollen PIN is indeed at the level of the wrist deep to compartment 4. I knew that the EPL was innervated by the PIN proximally however at the Arcade of Frohse the PIN was within normal limits. Hence the confusion.
The muscle belly was similar to the other side with no fatty atrophic change.

Is it possible that when the patient fell fracturing the distal radius an impact injury proximally has caused a post traumatic neuritis and the EPL dysfunction is a result? That’s me just speculating
