what is tfcc?

I cannot weight bare at present as I am only 3 weeks after the operation. It is very tender to touch at slightly hotter that the rest of the hand/wrist.
I have slight rotation but not alot as yet. It began to hurt when I was in the back slab and bandages and I put it down to chaffing but this continued after they were removed and the gp said it was infection. After taking anti-biotics this did not get better so the specialist said it was ECU.

He advised that as the bones were missing it was rubbing and causing the inflamation and he may need to remove the tip of the ulna.
