Beschreibung
Zusammenfassung:	The proximally fitting femoral component with adjunctive fixation screws replaces a natural femoral head and proximal femur of a patient during a partial or total hip replacement. The femoral component includes an intramedullary stem having a proximal portion and a distal portion, a neck extending from the proximal portion, and a ball removably attached to a tip end of the neck, the ball forming a ball and socket joint with the acetabular cup of a hip prosthesis. Fixation screws may be installed in the proximal portion of the stem for added rotational and axial stability when necessary. An alignment device is removably attachable to the femoral component for aligning screw holes in cortical bone of the femur with holes or bores in the proximal portion of the stem. The fixation screws may extend in an anterior posterior or medial-lateral plane.
