Abstract
A bone milling guide apparatus and method for preparing the proximal end of a femur to receive a hip stem prosthesis in snug-fitting relationship. The ball portion of the femur is removed using conventional surgical techniques to expose the underlying cancellous bone. An axial bore is drilled in the intramedullary canal to receive the distal portion of the hip stem prosthesis. The proximal end of the axial bore is reamed to form a tapered recess which is dimensionally configured to receive a portion of the external surface of the proximal end of the hip stem prosthesis. A tapered, hollow body is inserted into the tapered recess and supports a U-shaped template extending outwardly therefrom. Each arm of the U-shaped template is affixed to the tapered, hollow body on each side of a longitudinal slot in the side of the tapered, hollow body. A bone miller is inserted coaxially into the hollow body and tilted angularly through the longitudinal slot to remove cancellous bone in the region defined by the hollow body and the template.
