A hip stem provisional 10 having adjustable neck offsets is disclosed. Hip stem provisional 10 includes a stem part 12 and an attachable cone provisional 20. Cone provisional 20 includes a base 30 and a neck 40 shiftably connected to the base. Base 30 has a mounting surface 36 upon which neck 40 is shiftably seated. Neck 40 can be positioned along the length of mounting surface 36 at a plurality of discrete positions. In one embodiment of cone provisional 20, base 30 has an arcuate mounting surface 36, which allows neck 40 to be positioned along the length of the mounting surface at a plurality of discrete positions, each having a different neck offset and neck angle. In a second embodiment of the cone provisional 60, the base 70 has a flat mounting surface 76, which allows the neck 80 to be positioned along the length of the mounting surface at a plurality of discrete positions, each having a different neck offset, but having a fixed neck angle.
