Disclosed is a modular femoral prosthesis having a neck element 18 that can be selectively positioned atop a stem element 12 by inserting a grooved shaft 26 that extends downward from the bottom of the neck element 18 into a corresponding slotted recess 32 originating on a top portion of the stem element 12 and continuing longitudinally partially therethrough. The axial orientation of the neck element 18 relative to the stem element 12 can thus be rotated accordingly during insertion of the grooved shaft 26 into the slotted recess 32. The stem 13 can be cylindrical in form or tapered. Locking screw 30 is provided to secure the neck element 18 to the stem element 12.
