Based on a design philosophy with over 20 years of clinical success,
the EMPERION™ Modular Hip System combines a proven design with
modern technology. The result is the next step in hip evolution: a
simpler, more versatile hip system that delivers enhanced
performance.
The Ultimate in Versitility
The comprehensive implants of the EMPERION◊
Modular Hip System are designed to address the sizing needs of
nearly any femur, thereby restoring the natural kinematics of the
patient’s hip.
An effective implant for both primary and revision
procedures
Addresses the proximal/distal mismatch
Offers infinite stem to sleeve version control
Comes in three stem lengths: primary, standard
revision, long revision (bowed)
Two offset options for each primary length stem
Two calcar options for standard revision stems:
neutral and +10
Three calcar options for long revision (bowed)
stems: neutral, +10 and +20
Two sleeve lengths: 40mm and 60mm
Up to 16 different proximal sleeve options for each
stem size
Enhanced Performance Through Innovation
The EMPERION◊ system ushers in a
new age of proven simplicity. By incorporating cutting-edge
technology into the system’s design, the EMPERION◊
system delivers enhanced performance versus competitive
systems.
Every EMPERION◊ sleeve uses
POROUS PLUS™ HA coating with a 50 micron hydroxyapatite
layer applied onto the porous sintered-bead coating. Studies
have shown this to be the optimal HA coating thickness to
ensure proper mechanical integrity and have optimal
attachment strength.1,2 Furthermore, the EMPERION◊
system is the only system of this style that has this type
of coating available.
Circulotrapezoidal neck provides maximum ROM
with minimal impingement, thereby reducing the risk of
dislocation and wear.. 3
The polished bullet tip of the stem reduces
the magnitude and increases the distribution of pressure on
the bone, resulting in easier stem insertion and possibly
less thigh pain.4

With over 85,000 stems successfully
implanted since 1997, SYNERGY◊ Hip System has been one of
the fastest growing hips in orthopaedics. Why? Because SYNERGY◊
is a complete system, with state-of-the-art options, that utilizes
simple, efficient instrumentation.
-
Two simple instrument trays arranged in the
order of surgery to allow a simple, efficient operation.
-
Circulotrapezoidal neck provides increased ROM
and can lead to less dislocations.
-
3° taper design, similar to the natural canal’s
2°-4° taper, provides optimal stability and fixation.
-
Optimized neck taper and femoral head design
allow for 11mm of neck length adjustment without a skirted head.
Femoral heads with skirts decrease ROM and can increase
dislocation.
-
Dual offsets that stay at a constant 131°
provide a restoration of the patient’s biomechanics without
affecting leg length.
-
1mm size increments allow for better match.
-
Roughcoat sintered bead porous coating allows
for scratch fit and stresses the bone for bone ingrowth.
-
Anterior/posterior fins are shown to provide 20%
more stability than a similar design without fins.
-
Distal tip of SYNERGY◊ Hip System is
polished and bulleted to reduce thigh pain.

CONQUEST◊ FX Fracture Management
System also uses the SYNERGY◊ Hip System’s efficient
instrumentation. More information on CONQUEST◊ FX can
be found in the Fracture Management section of this brochure.
ECHELON◊ Primary implants are part of a
family of femoral stems that address primary and revision
situations. With one set of instruments, a variety of stems can be
implanted.
Cementless total hip arthroplasty has provided a
proven method of treatment for several decades. The ECHELON◊
Primary Hip system incorporates the design concepts learned
throughout this period to offer a femoral implant system that
addresses the clinical needs of both surgeons and patients alike.
By offering dual offset implants in 1 mm increments
and simple yet precise instrumentation, the ECHELON◊
Primary Hip system offers the surgeon unprecedented intraoperative
flexibility. For the patient, ECHELON◊ Primary stems are
designed with the goal of providing long-term, pain-free restoration
of joint function and normal hip biomechanics.

Neck Offset Options
Standard and high offset options are available to ensure the
appropriate joint tension.
Optimized 12/14 Taper
Modular femoral heads are locked onto the stem with
an optimized 12/14 taper which contributes to an increased
range of motion.
Neck Geometry
Circulotrapezoidal neck provides increased range of motion
compared to a circular neck of the same strength. Polished
surface improves fatigue strength.
Driving Platform
The ECHELON◊ implants feature a threaded
driving platform with an eliptical slot for rotational and
axial implant control during insertion.
Shoulder Relief
Lateral shoulder is rounded to minimize the risk of
fracturing the greater trochanter during stem insertion.
Lateral Proximal Flare
ECHELON◊ has a 3 degree proximal
anterior / posterior flare to improve proximal fill, without
preventing implant seating.
Porous Coating
RoughCoatTM porous coating increases the
friction between the implant and the bone, improving implant
stability and providing a porous surface for bone ingrowth.
Material
All ECHELON◊ implants are manufactured from
Cobalt Chromium allowing for extensive porous coating of the
stem.
Size Range
ECHELON◊ Primary stems are offered in
1mm increments to minimize bone removal and provide optimum
canal fill.
Distal Flutes
The ECHELON◊ system offers distal flutes
to increase rotational stability.
Distal Slot
The distal slot eases stem insertion, reduces the
risk of fracture and reduces distal stem stiffness.
Distal Bullet Tip
The bullet tip reduces the stress between the
distal implant tip and the bone to minimize end-of-stem
thigh pain

Can be used with the direct anterior surgical
approach.
The Evolution of a Proven Design
The ANTHOLOGY◊ Hip System is an improvement
on the designs of other clinically successful Mueller
"flat" tapered stem designs. We offer superior ROM,
along with design features that will achieve excellent
fit and rotational stability. Superior Sizing ANTHOLOGY◊ Hip System offers the ability to
match all femur types and sizes, increasing in
predictable 1.5mm incrementals. ANTHOLOGY◊
stems also increase in size at greater rate proximally
than distally to ensure proximal loading.
Superior ROM
With 144° of AP ROM with a 32mm head ANTHOLOGY◊ lessens
the chance of neck impingement that can lead to dislocation.
Rotational Stability
The flattened medial surface of the ANTHOLOGY◊ stem
creates corners that contact cortical bone, enhancing rotational
stability.
Innovative Instrumentation
Not every surgical approach is the same, so not all
instrumentation should be the same. With the ANTHOLOGY◊
Hip System, surgeons are able to choose instruments specifically
designed for the direct anterior approach.
