Instrument set for preparation of the seat for the femoral component of a non-cemented hip prosthesis

摘要

The rasps of a first set of metaphyseal rasps are capable of working, in a first stage, the femoral canal in the zone of the metaphysis until the bony part K1, K2 is reached and cut into to form the metaphyseal seat for a femoral component of a hip prosthesis, the rasps having guide stems which act in the zone of the diaphysis. The rasps of a second series of sub-metaphyseal and diaphyseal rasps are capable of working, in a second stage, the femoral canal in the sub-metaphyseal zone and the adjacent zone of the diaphysis, until the bony part K3 is reached and cut into to complete the seat for the femoral component.
