Surgical Technique for Femur Nail - ARZZT

ARZZT Techniques
Surgical Technique for Femur Nail
Introduction
One of this implant favorite utilization features is the distal locking security, since
inside the technique use, practical and simple, a constant symmetry is maintained
between instrumental set and implant, saving surgical time and reducing the use
of images intensifier.
These innovations result in the surgical procedure success, diminishing
considerably locking time for patient´s benefit since ischemia short time reduces
deep veined thrombosis risk, of infection by the minimum approaches that are
carried out, patient´s fast recovery to incorporate in short time to rehabilitation and
his work and life routine.
Having more advantage since in necessary case of dynamiting the system, it counts
with a proximal orifice so that upon withdrawing one of the proximal screws the
other one works as dynamic locking, this in cases of consolidation or
pseudoarthrosis delay.
This dynamic system controls deformities in rotation and flexion but allows axial
load transfer through almost the complete bone; it is use in axially stable fractures
and some pseudoarthrosis. The static system controls the rotation, flexion and axial
load and makes the implant a greater load-bearing mechanism reducing fatigue
resistance risk, it is particularly useful in comminuted fractures and not isthmian.
Implant design
ARZZT intramedullary femur nail comes presented as solid and cannulated nail,
steel or titanium with two holes for fixed distal locking and two for proximal locking,
one of them fixed and the other dynamic, where conical head screws are placed for
cortical bone greater subjection.
ARZZT intramedullary femur nail sizes are 9 mm diameter with 320 mm to 420
mm length; 10 mm diameter with 360 mm to 420 mm length, 11 mm diameter
with 340 mm to 420 mm length and 12 mm diameter with 340 mm to 420 mm
length. Each measure with a 20 mm difference.
Nail metal alloys that guarantee its resistance is manufactured in STEEL 316 LS and
TITANIUM 6AI4V, each to be use as the Orthopedics surgeon considers better.
ARZZT femur nail has been designed to be use in diaphysial fractures, of simple,
complex or comminuted lines, up to 5 cm proximal to distal femur metaphyseal.
