<strong>Operative</strong> <strong>Technique</strong><br />
<strong>AxSOS</strong> Compression Plates<br />
The <strong>AxSOS</strong> Small and Basic Fragment<br />
<strong>System</strong>s function in the same general<br />
operative manner as the SPS Small<br />
and Basic Fragment <strong>System</strong>s in the<br />
conventional non-locking mode.<br />
The procedure below illustrates how<br />
to convert an <strong>AxSOS</strong> Plate Hole from<br />
a compression mode to an un-locked<br />
mode.<br />
<strong>AxSOS</strong> Compression Plates<br />
or SPS Compression Plates<br />
The <strong>AxSOS</strong> Compression Plate<br />
should not be confused with the SPS<br />
Compression Plate. The standard SPS<br />
Plate cannot be locked, and therefore<br />
should not be used with Locking Screws,<br />
Locking Inserts, or Cable Plugs.<br />
The <strong>AxSOS</strong> Compression Plate can<br />
be used both in compression and/or<br />
locking mode.<br />
Each system has its own Reference<br />
Numbers, and there are 2 visible<br />
differences between the plates.<br />
The <strong>AxSOS</strong> plate has a “matte” finish,<br />
while the SPS plate has a “polish” finish.<br />
Second, the plates have different tapers<br />
at the plate ends as illustrated in (Fig. 1).<br />

Bending<br />
If the plate is used in a fully locked mode,<br />
plate bending is not recommended due<br />
to possible hole deformity and inability<br />
of Locking Insert placement.<br />

Compression Plates Cortical Screws Locking Screws<br />
Small Fragment 3.5mm 4.0mm<br />
If the plate is used in a hybrid mode<br />
(compression with appropriate cortical<br />
screws and locking screws), the plate<br />
should only be bent at the level of the<br />
fracture line between the compression<br />
holes.<br />
Hybrid Mode Screw Insertion<br />
When using the plate in a hybrid mode,<br />
it is essential to insert the Cortical<br />
Screws for axial compression before<br />
inserting any Locking Screws.<br />
