UNIFLEX
Nailing System
NIFLEXIBILITY
Titanium Alloy Construction
Compared to stainless steel, titanium alloy provides added
strength for internal fixation of shaft fractures with a lower
modulus of elasticity. The resultant flexibility aids in the
insertion of the nail and results in increased load transfer
to the bone to stimulate fracture healing.
Convenient, Sterile Packaging
Implants are packaged pre-sterile for convenience
and assured sterility in the operating room.
Simplified Nail Removal
The end cap threads into the proximal end of the nail,
reducing the possibility of fibrous tissue growth into the
threads. Upon removal of the end cap, threads are clear,
facilitating extraction.
Faster Insertion with Pathfinder™ Tips
The tapered design of the Pathfinder Tip aids passage
down the intramedullary canal and across the fracture site,
while reducing the risk of cortical impingement.
Simple, Accurate Instrumentation
Precise reproducible instruments thread easily into the
nails, providing exceptional control and rotational stability
during insertion and extraction. One thread
size for all nails simplifies instrumentation.
Instruments are well organized in a single
sterilization case for convenience.
Surgical Latitude
The Uniflex Family of Intramedullary Nails can be
utilized in a reamed or nonreamed mode, based on
surgeon preference and individual patient requirements.
For Your
Most
Demanding
Cases
Titanium alloy provides a unique
blend of strength and flexibility, ideal
for intramedullary fixation. The yield
strength of titanium alloy is twice that
of stainless steel and its ultimate tensile
strength is almost 25% higher. In
addition, the combined mechanical
properties of high strength and a
lower modulus of elasticity allow the
Uniflex Nail to potentially offer
reduced implant failure and improved
stimulation of fracture healing.

roven Küntscher concept of a full
longitudinal slot promotes healing by
allowing micromotion at the fracture
site. The longitudinal slot compresses
during insertion making the nail more
“forgiving” and requiring overreaming
of only 1-1.5mm. ■ The yield strength
of titanium alloy is twice that of stainless steel and its ultimate tensile strength is almost 25% higher. ■ Two proximal
reconstructive screw holes are placed at a 125o neck/shaft angle and anteverted left
and right 9o to accommodate the anteversion of the femoral neck. Distal screw holes
are positioned to capture fragments close to the femoral condyles. ■ Much stronger
than stainless steel, self-tapping titanium screws allow for easy insertion and
increased strength and are available in 9 lengths. ■ Uniflex Nails are left
and right bowed and are available in diameters from 10mm to 16mm and lengths
from 32cm to 48cm.
Case Data

in a motorcycle accident.

Nail in reconstructive fixation with fracture healing and no signs of avascular necrosis.

uch stronger than stainless steel
in yield strength, and 25% higher
in ultimate tensile strength, selftapping titanium screws allow
for easy insertion, increased
strength, and are available in
10 lengths. ■ In addition, the
combined mechanical properties of
high strength and a lower modulus of elasticity allow the Uniflex Nail to offer a
potential reduction of implant failure and improved stimulation of fracture healing.
■ Distal screw holes are positioned to capture fragments close to the femoral
condyles. ■ Uniflex Tibial Nails are available in lengths from 24cm to 38cm in the
8mm and 9mm diameter nails and 24cm to 42cm in the 10mm through 14mm
diameter nails.

umeral nails of titanium alloy
provide a unique blend of strength
and flexibility. ■ Ideally suited for
intramedullary fixation, the yield
strength of titanium alloy is twice
that of stainless steel and its ultimate
tensile strength is almost 25%
higher. ■ In addition, the combined
mechanical properties of high strength and a lower modulus of elasticity allow
the Uniflex Nail to offer a potential reduction of implant failure and improved
stimulation of fracture healing. ■ Self-tapping titanium screws allow for easy
insertion and increased strength, and are available in 6 lengths. Uniflex
Humeral Nails are available in diameters of 8mm and 9mm and lengths of
18cm to 28cm.
Case Data

Preoperative
Postoperative
Indications
Most fractures of the humerus will
heal in a satisfactory fashion without operation. However, the
Uniflex Humeral Nail System has
been designed to treat certain
difficult humeral fractures in
which noninvasive treatments
have historically failed to give
predictable results.

Fracture
Simple, Accurate
Instrumentation
Although proximally attached distal
alignment guides for locking distal
screws have not generally performed
well in the femur, the humerus is
shorter and lighter and is exposed
to milder intraoperative stresses,
allowing use of the distal target
guide. This greatly simplifies the
need for intraoperative imaging.
Instruments thread easily into the
nails providing exceptional control
and rotational stability during
insertion and extraction. One thread
size for all nails simplifies instrumentation. Instruments are well
organized in a single sterilization
case for convenience.
The Uniflex® Humeral Nail System
was developed in conjunction with
Ralph B. Blasier, M.D., Chief of
Orthopaedics, Grace Hospital,
Detroit, MI.

is extremely important
to ream the entry portal
to 14mm in diameter to
a depth of approximately
3" (8 cm) below the

Reamer System™
Features
• The Küntscher style head design has proven to provide better venting than many
competitive reamer heads.1,2
• Reversible shaft design provides easier removal intraoperatively.
• One shaft diameter (8mm) for use with all reamer head diameters (8mm-20mm).
• A simple more convenient system that saves time.
• Extra long shaft length (52cm) allows greater distal reaming when necessary.
