T2 Tibial Nailing System - Stryker

Operative Technique
Freehand Distal
Locking
The freehand technique is used to insert
Locking Screws into both the M/L and
A/P holes in the nail. Rotational
alignment must be checked prior to
locking the nail statically.
Multiple locking techniques and
radiolucent drill devices are available
for freehand locking. The critical step
with any freehand locking technique is
to visualize a perfectly round locking
hole with the C-Arm.
The center-tipped Ø4.2×130 Drill
(1806-4280S) is held at an oblique
angle pointing to the center of the
locking hole (Fig. 25 and Fig. 26).
Upon X-Ray verification, the Drill is
placed perpendicular to the nail and
drilled through the medial cortex.
Confirm in both the A/P and M/L

20mm
planes by X-Ray that the drill passes
through the hole in the nail.
Alternatively, the Screw Gauge can be
used to determine the screw length.
After drilling both cortices the screw
length may be read directly off of the
calibrated Short Screw Scale (1806-
0360) at the green ring on the centertipped
Drill (Fig. 27).
As detailed in the proximal locking
section (Fig. 21, p. 14), the position of
the end of the drill is equal to the end
of the screw as they relate to the far
cortex.

Routine Locking Screw insertion is
employed (Fig. 28) with the assembled
Screwdriver Shaft and Teardrop
Handle.
Alternatively, the 3.5mm Hex Self-
Holding Screwdriver Extra-short
(1806-0203) can be used for the
screw insertion.
