Re: Перелом около протеза

I agree with Dr. Seligson (as you mentioned) about retrograde nails being best option for distal femur fractures proximal to total knee replacement.
Although longer retrograde nails are now preferred, the shorter retrograde nails still work.
I think you are unnecessarily concerned about going through the condyles of the femoral component. The ACL is already gone in this patient (clearly no
tibial attachment) and the PCL (if still present) is not typically injured by
retrograde nail. The surgical approach is actually quite easy and much easier than antegrade femoral nailing with such shaft deformity. I don't think you will injure the knee prosthesis and even if it needed revision in the future, such revision would be facilitated by a well aligned and healed supracondylar fracture.
My suggestion you consider retrograde nail and put the largest diameter nail that you have that fits and the longest nail that you have that fits up the
deformed medullary canal. Don't perforate the cortex proximally trying to put a
long straight nail in a crooked canal; just accept whatever length you can get. If it's quite short then adjust his rehabilitation accordingly with longer use of a brace, crutches and limited weight bearing.
Good luck
