For locking/oblong hole only use cortical screws ø3.5!
For round hole only use cortical screws ø2.5!
•
For the primary fixation of the plate shaft, a non-locking cortical
screw 3.5 mm (gold) can be inserted into the oblong hole. For this
purpose use a double drill guide and a twist drill ø2.7 and drill to
the desired depth.
•
Then determine the length of the screw using the depth gauge and
insert a screw of appropriate length by using the screwdriver T15.
The plate can be pulled against the bone using this screw.
N
OTE
:
Securing the oblong hole before inserting screws in other plate
holes can facilitate the positioning of the plate on the bone.
•
To insert a non-locking cortical screw 3.5 mm (gold) in the gliding
hole, proceed as described above.
N
OTE
:
If a combination of non-locking and locking screws is used, non-
locking screws must be inserted first.
•
To improve handling the aiming arm can be removed leaving the drill /
K-wire in place providing necessary stability. The adjusting ring can then
be freely moved to allow more space for the subsequent surgical steps.
N
OTE
:
To ensure the temporary stability of the reduction, do not remove
the K-wire or twist drill until at least one additional locking screw has
been inserted.
•
To insert non-locking cortical screws 2.5 mm (gold) in the metaphy-
seal area (round hole) of the plate, please follow the instructions on
page 16 (locking screws 2.7, light blue). The torque limiter is not
applicable for non-locking screws.
•
Check the plate position using fluoroscopy and adjust if required.
