it will free up in time especially if your active using your hands with tools and stuff, mine was "healed" after a year but took a couple more to free up again to 100% because i did no more rehab i just wanted to get back to work
my surgeon wanted to take the pin out of mine because the head was protruding more than he liked, the original plan was to leave it in, fuck that no more cutting..i told him i`d get back to him on the subject...lol
