HISTOLOGY OF THE FEMUR AFTER CANCELLOUS IMPACTION GRAFTING USING A CHARNLEY PROSTHESIS

We report the histologic findings of a retrieved femur 6 months after a cemented hip revision with a Charnley standard prosthesis and impact ion of morselized allograft. Most transplanted areas were revascularis ed. Ln the proximal femur there was new bone formation peripherally, b ut a substantial amount of fibrous stroma embedding graft pieces close r to the cement. In the diaphysis new bone formation had proceeded to within less than 0.5 mm of the cement.
