Pre-operative Planning

The objectives of pre-operative planning are to
define:
• Pre-operative leg length
• Acetabular component size and position
• Femoral component size
• Femoral offset and center of rotation
The Avenir Complete Hip System provides X-ray
templates with 100%, 110%, 115%, and 120%
magnification (Figure 1).
It is recommended to use a radiographic marker
to assess the X-ray magnification and select the
appropriate template.
It is also recommended that templates are
positioned over the AP X-rays to best decide the
correct implant size and center of rotation.

Digital Pre-operative Planning

Avenir Complete Femoral System digital templates
are available through various digital template
providers. When using digital templating for
a primary Total or Hemi Hip Replacement, it is
necessary to use a magnification marker with a
known dimension. This is required to calculate
the correct magnification. As soon as the correct
magnification has been determined, the system can
be used with aiming at best deciding the correct
implant size and center of rotation (Figure 2).
