<strong>Operative</strong> <strong>Technique</strong><br />
Apposition/<strong>Compression</strong> Locking Mode<br />
In transverse, axially stable fracture<br />
patterns, active apposition/compression<br />
increases fracture stability, may<br />
enhance fracture healing, and may<br />
allow for early weight bearing. The <strong>S2</strong><br />
<strong>Femoral</strong> <strong>Nail</strong>, <strong>Compression</strong> provides<br />
the option to treat a femur fracture<br />
with active mechanical apposition/<br />
compression prior to leaving the<br />
operating room.<br />
10mm<br />
Caution:<br />
Distal locking with at least two<br />
Fully Threaded Locking Screws<br />
must be performed prior to<br />
applying active, controlled apposition/compression<br />
to the fracture<br />
site (see page 22, Fig. 42).<br />
Fig. 46<br />
If active apposition/compression is<br />
required, a Partially Threaded Locking<br />
Screw (Shaft Screw) is inserted via the<br />
Target Device in the dynamic position<br />
of the oblong hole. This will allow for<br />
a maximum of 10mm of active, controlled<br />
apposition/compression.<br />
In order to insert the Partially<br />
Threaded Screw (Shaft Screw), drill<br />
both cortices with the Ø4.2×340 Drill<br />
(1806-4260S). Next, drill the near cortex,<br />
ONLY, with the Ø5×230mm Drill<br />
(1806-5000S).<br />
Note:<br />
After the opposite cortex is drilled<br />
with the Ø4.2×340mm Drill, the<br />
correct screw length can be read<br />
directly off of the calibrated Drill<br />
at the end of the Drill Sleeve<br />
(Fig. 46)<br />
After the Shaft Screw is inserted, the<br />
<strong>Nail</strong> Holding Screw securing the nail<br />
to the insertion post is removed,<br />
leaving the insertion post intact with<br />
the nail (Fig. 47). This will act as a<br />
guide for the <strong>Compression</strong> Screw.<br />
The <strong>Compression</strong> Screw is inserted<br />
with the Long Screwdriver Shaft<br />
and Teardrop Handle through the<br />
insertion post (Fig. 48). As The<br />
<strong>Compression</strong> Screw is advanced<br />
against the 5mm Partially Threaded<br />
(Shaft Screw), it draws the distal fracture<br />
fragment toward the fracture site,<br />
employing active apposition/compression.<br />
Note:<br />
Apposition/compression must be<br />
carried out under X-Ray control.<br />
Over compression may cause the<br />
nail or the Shaft Screw to fail.<br />

Note:<br />
After inserting the <strong>Compression</strong><br />
Screw, the End Cap can no longer<br />
be used.<br />
