Product Overview

The Zimmer Natural Nail System is a system of
intramedullary nails, screws, instruments and other
associated implants that are designed to provide
stable internal fixation for fractured long bones. The
nails have been designed for specific applications to
help restore the shape of the fractured bone to its
natural, pre-injured state.
The Cephalomedullary Nail is designed to treat
fractures of the femur, especially intertrochanteric
and subtrochanteric fractures. The nail features a
small proximal section that is designed to minimize
the amount of bone that must be removed for nail
insertion. A lag screw is placed through the nail
into the femoral head to secure the nail in place
proximally and help control the different segments
of the bone while healing occurs. Screws are placed
through the nail distally to further secure the implant
in place and maintain length and alignment while
healing occurs.
A choice of Asia and long nails as well as nails of
different diameters and centercolumn-diaphyseal
(CCD) angles are available to best match the
individual anatomy of the patient.

Precision instrumentation is provided to help implant
the nail. Many of the instruments and implants
feature a color coding system to help the surgical
team use the system. Certain instruments are not
color coded. The color coding system is referenced
in the technique. A wall chart (97-2493-007-00)
is also available to help explain the color coding
system.
