2.7 Assembly of the trial femoral component
Stem:
it is recommended to go a size smaller than the reaming diameter, but this will be at the sole discretion of the surgeon. For 70 mm stems
it is recommended to use the same diameter, and for 120 and 200 mm stems, to use a size which is smaller than the reaming diameter to avoid
the “tip effect”. It is assembled by screwing the stem into the distal part of the femoral component, using the screws provided in Box 7 for that
purpose.
Supplements:
its pre-mounted screw is screwed into the threaded holes of the femoral component (see Annex VI).
Position between the stem and the femoral component:
if it has been necessary to perform an offset, fit the stem while ensuring that the mark of
the stem coincides with the number displayed on the femoral component which originates from the reading which was last taken with the eccentric
positioner on the insert positioner (see 2.4 Reading of the Offset).
Using the femoral component inserter/extractor, insert the femoral component into the femur, making the final adjustments to adapt it to the femoral
cuts. Once inserted, check that it has been adjusted correctly.
Then remove the femoral component, ensuring that the marked number has not changed position, and said offset position will be transferred to the
final prosthesis.
