Drill and determine screw length
Instrument
310.284 2.8 mm Drill Bit, quick coupling, 165 mm
Insert the drill bit and drill carefully, until the level of the
subchondral bone is reached. Confirm drill bit position under
imaging.
Read the required screw length directly off the calibrated drill
bit at the back of the drill sleeve.
Remove the drill bit and drill sleeve.
Caution:
Do not penetrate the articular surface.
Notes:
– The drill bit can only be inserted if the drill sleeve is
properly locked in the centering sleeve.
– Do not change the position of the centering sleeve.
Alternative technique: Measure using depth probe

System
Alternatively, the depth probe can be used for screw length
determination.
Assemble the depth probe with its outer sleeve.
Insert the depth probe through the drill sleeve and advance
it until resistance of the subchondral space is felt. Monitor
under imaging. Read the screw length on the fenestrated
scale of the depth probe.
Remove the drill sleeve.
Note:
Do not change the position of the centering sleeve.
