Proximal locking can be performed with the leg in full
extension. this neutralizes the deforming forces on proximal
fragments caused by the quadriceps mechanism and relieves
the pressure on the soft tissue usually associated with tibial
nail insertion instruments. this position also facilitates
assessment of rotational alignment prior to locking.
use the dual-core locking screws (gold) only in combination
with the two oblique proximal locking holes (ProxImal
oblIque, dIStal oblIque) and aP proximal locking hole
for all nail diameters.
use the 3.2 mm drill bit for the 5.0 mm dual-core
locking screws.
the aiming arm can target all three proximal oblique
locking options:
1
the oblique locking option (ProxImal oblIque)
corresponds to the most proximal locking position.
Inserting a tibial nail end cap with this locking screw will
create a fixed-angle construct.
2
the oblique locking option (dIStal oblIque) corresponds
to the second proximal locking position.
3
the oblique locking option in anteroposterior direction
(aP) corresponds to the third proximal locking position.
