Just to thank everyone a tell you that my son is coming home after a successful surgery. The tumor is out, the leg is still there, although with an artificial knee and the top third of the tibia replaced with an allograft.
He will spend two months with his leg in a brace and will have to relarn to walk. There are also another eight chemo session which will take us into April/May, but all in all a good result.
Lifting from the floor is out though.
