Straight Stem Impactor Curved Stem Impactor Use a mallet and stem impactor to further advance the stem into endosteal canal. Offered Straight and Curved Stem Impactors enable different surgical approaches. The prosthesis should be seated until most proximal portion of the coating surface is in line with the neck resection face. The interference between implant and broach is 0.5 mm per side. Mild resistance is expected during implantation. If the prosthesis could not be advanced into canal properly, remove the prosthesis and repeat the canal broaching procedure is suggested. Note: If the stem impactor impinges with greater trochanter, any impaction may lead to bone fracture. A final trial reduction may be performed if desired to re-evaluate stability and leg length by using the femoral head trials. After the appropriate femoral head size has been determined, place it onto the cleaned and dried taper with manual twist. Using the head impactor, engage the head with several gentle taps until it is firmly set. Femoral Head Impaction Stem Impaction 5
