Thanks for all your thoughts, did not go as planed

, got the top two screws out but both the bottem ones where broken, they tried but failed so the nail,(pin) is still there

.
At least they got the two top screws out

, they had to cip bone away from around the top of the nail before they tried getting it out, & from around the two top screws, so my knee is swollen & B****y painful & I will be on crutches for a few days or more

Thanks again for all your messages.
Chris.
