An improved U-shaped base guide for rigid attachment to the proximal end of a femur with at least one pin through the femoral cortex to enable cement to be applied to the femoral canal under pressure and having at least a first orifice in one side of the U-shaped guide and a second orifice in another side of the U-shaped guide in axial alignment with the first orifice. The second orifice is larger in cross-section than the attaching pin and an insert easily penetrable by the attaching pin is removably placed in the second orifice whereby the attaching pin in passing through the first orifice, the femoral cortex and the easily penetrable insert may deviate from axial alignment between the first and second orifices without striking the base guide.
