23 | Zimmer Natural Nail – Cephalomedullary Asia Nail Surgical Technique
Distal Targeting For Asia Nails (cont.)
The nail utilizes a 5.0 mm screw distally. The screw
packages are labeled with the color red. The distal
hole and slot in the nail allows for standard or fixed
angle locking. To achieve standard locking, choose a
partially threaded 5.0 mm screw. To achieve a fixed
angle construct, choose a fixed angle 5.0 mm screw
(Figure 34, applicable for long nails only).
Choose the appropriate length screw based on the
depth gauge or drill bit reading. Use the 3.5 mm
hex screwdriver to place the screw bicortically
through the bone.
If using the captured screwdriver, place the
appropriate screw on the 3.5 mm hex and tighten
the screw to the captured screwdriver by turning
the knob next to the handle clockwise.
Caution: Do not drive the screws into the bone
under power, as damage to the bone, screws
and nail could result.
Remove the screwdriver and cannula. If desired,
repeat these steps to place another screw in the
other hole or slot. If not previously done, remove
the lag screw cannula.
