Starting Point Location - Zimmer Biomet Zimmer Natural Nail Manual

Starting Point Location

Palpate the greater trochanter manually. Incise the
skin starting about 2 cm proximal to the tip of the
greater trochanter and extending proximally 2-3
cm. Dissect through the tissues splitting the fascia
lata down to the bone. Assemble the starting point
locator inside the entry cannula. Place the tip of the
starting point locator through the incision down to
the tip of the greater trochanter (Figure 1).
Place the 3.0 mm pin through the center hole of the
starting point locator.

Use the C-arm to visualize the pin's position from
an A/P and Lateral view. The pin should be inserted
at the tip of the greater trochanter in the posterior
portion of the middle third of the trochanter. The pin
should not be on the lateral portion of the greater
trochanter, it must be on the tip. A starting point
slightly medial to the tip of the trochanter is also
acceptable.
Note: A starting point lateral to the tip of the
greater trochanter may lead to a varus reduction
following nail insertion.
If necessary, remove the pin and move it into the
hole in the starting point locator that will align the
pin correctly with the tip of the greater trochanter.
Technique Tip: It is recommended to take a
true lateral view (femoral head, neck and shaft
in straight line after insertion of the guide pin).
