1. An orthopaedic fixation assembly adapted to be implanted in a bone of a patient, comprising:
a main body adapted for insertion into the bone, the main body comprising a longitudinally extending stem, the longitudinally extending stem having a proximal end, a distal end, and a cavity body defining an interior of the longitudinally extending stem between the proximal end and the distal end;
a spindle structure configured to be attached to the proximal end of the longitudinally extending stem of the main body, the spindle structure comprising a housing having an annular flange configured to interface with an osteotomy surface;
an anchor plug comprising a top portion, a bottom portion, a peripheral side wall and an elongated shaft extending from the bottom portion, the anchor plug configured to be received into the interior of the cavity body and being securable to the longitudinally extending stem via complementary mating surfaces located in the interior of the cavity body and on the peripheral side wall of the anchor plug; and
an end cap configured to secure the anchor plug within the cavity body by engaging with the distal end of the longitudinally extending stem.
