Determine length of screw
Required instruments
LCP Drill Sleeve 2.7 (head LCP 2.4), with Scale up to 60 mm,
for Drill Bits
2.0 mm
323.061
Drill Bit
2.0 mm, with double marking, length 140/115 mm,
3-flute, for Quick Coupling
323.062
Depth Gauge for Screws
2.0 and 2.4 mm, measuring range
up to 40 mm
319.005
Depth Gauge for Screws
2.7 to 4.0 mm, measuring range
up to 60 mm
319.010
Determine the required length of the screw by using the scale
on the drill guide. If a single marking is visible on the drill bit,
the scale from 0–30 mm applies; if a double marking is visible,
the scale from 30–60 mm applies.
Option:
Use a Depth Gauge 319.005 to check length.
Note:
For all screw types: using the exact length indication
will lead to a screw which ends exactly at the exit point of the
bone for all measuring devices contained in the set. Thus for
bicortical screws (shaft), the chosen screw must be a little
longer than the indication. Screws in the joint must be a little
shorter.
If Depth Gauge 319.010 is used for 2.7 mm screws, subtract
4 mm from the indication to obtain a correctly comparable
screw length.
