Surgery scheduled 3/15/17 for bar and 3 screws removal. Scared b/c I have been told, "slender, white And over 60" there's a good possibility my femur will snap. Told 14/16 weeks for holes in the bone to heal, The tendon is rubbing across the screw top, per MD. Are there braces, stabilizers to help Protect? Thank you, Pam
