Using the Radiolucent Drive
Before positioning the Radiolucent Drive, align the
image intensifier until the distal locking hole of the
medullary nail is round and easily visible (Fig. 1).
After the incision, position the Radiolucent Drive and
center the drill bit tip over the locking hole. On the
monitor of the image intensifier, you can see both the
drill bit and the target rings of the drive.
Swing the drive up and center it precisely so that the
drill bit appears as a round point and the locking hole
is visible around it. The target rings also assist center-
ing. The locking hole can now be drilled directly (Figs.
2 and 3).

Notes:
–
Grip the coupled Radiolucent Drive tightly when
switching on the power tool, particularly if the
power tool is held face down.
–
Only special 3-flute spiral drill bits can be used.
Your DePuy Synthes representative will be glad to
provide you with additional information on which
drill bits can be used.

–
Handle the Radiolucent Drive with great care.
Do not allow contact between the drill bit and the
medullary nail.
–
Depending on the setting of the image intensifier,
a zone may appear in the rear of the Radiolucent
Drive that is not radiolucent. However, this does
not inhibit aiming and working with the device.
–
To protect the gears, the Radiolucent Drive is
equipped with a slip clutch that disengages in
case of an overload and emits an audible rattling
noise.

–
The following procedures can cause an overload:
- Correcting the drilling angle when the cutting
edges of the drill bit are completely in the bone.
- Hitting the nail with the drill bit.
For further information on the Radiolucent Drive and
on the special 3-flute spiral drill bits please consult the
relevant Instructions for Use (036.000.150) or your
local DePuy Synthes office.
–
Drilling can continue after making the following
corrections:
- Correcting the drilling angle: Remove the drill bit
until the flutes are visible and then restart the drill-
ing.
- Hitting a nail: Remove the drill bit until the flutes
are visible, and re-aim the drill bit or exchange the
drill bit if necessary.
