Paprosky Classification of Femoral Bone Loss
Type I - minimal metaphyseal bone loss
Type II - extensive metaphyseal bone loss, minimal diaphyseal bone loss
Type IIIA - extensive metaphyseal and diaphyseal bone loss with greater or equal to 4 cm intact diaphysis for "scratch fit"
Type IIIB - extensive metaphyseal and diaphyseal bone loss with less than 4 cm of intact diaphysis
Type IV - extensive metaphyseal and diaphyseal bone loss with a non-supportive isthmus
Treatments
I - cylindrical fully porous coated stem (consider tapered proximal geometry or cemented stem)
II - diaphyseal engaging stem
IIIA - diaphyseal engaging stem (impaction grafting, modular stems)
IIIB - tapered stem with splines for rotational stability (impaction grafting, modular stems, PFR)
IV - PFR, impaction grafting with cemented stem, allografts
