The correct stem size will have been determined already
from the previous intramedullary reaming. if the 12 mm
intramedullary reamer has been used, select the 12 mm
broach and attach it to the broach handle. make sure that
the goniometer is in place on the broach handle.
Drive the broach into place, carefully checking that
its anterior fin is aligned with the anterior aspect of
the bicipital groove. This will ensure good distal stem
orientation (anatomic version) for an optimised press-fit
(Figure 59).
Drive the broach down carefully, (to avoid any cortical
bone damage) until the rocking bar of the broach
handle is in full contact with bone, both at the anterior
and posterior aspects of the resection surface (Figure
60).
if there is cortical bone damage where the rocking
bar should contact bone, slide the broach handle
plate between the rocking bar and the bone resection
surface.
Read the angulation which is automatically indicated on
the instrument.
