Maxera™ Cup – Product Information
The Maxera Cup provides a large-head, ceramic-on-ceramic
option for the younger and more active patient. The cup is an
established hemispherical design8,11,12 that provides increased
stability2–6 with a familiar surgical technique. The Maxera Cup
presents orthopaedic surgeons with a system that offers
high range of motion1, 2 and a low-wear7–9 bearing to better
enable the restoration of a patient’s active lifestyle.

Patient Activity Levels
Large Diameter Heads Allow
Increased Range of Motion
The Maxera Cup is paired with BIOLOX®*
delta and BIOLOX OPTION Large
Diameter Heads (i.e., sizes 32mm,
36mm, 40mm, 44mm, 48mm):
• F or an identically placed cup and stem,
a larger head provides increased range
of motion before impingement and
reduces risk for dislocation1, 2

Large Diameter Heads Provide
Increased Stability
• Recent clinical studies show that large
diameter heads reduce the rate of
dislocation2–6
• A large diameter articulation offers
increased dislocation height (X > Y)

Maxera™ Cup – Product Information
Tough BIOLOX delta
Articulation Technology
Very Low Wear
High Fracture Resistance
• Ceramic surface hardness reduces
friction and improves wear7
• BIOLOX delta ceramic toughness and
bending strength are more than
double that of pure Alumina ceramics
through the addition of Zirconia and
Strontium Oxide7
• Favorable wetting characteristics
of ceramic contribute to better
lubrication and lower wear7–9
Excellent Biocompatibility
• An excellent choice for patients
who may be sensitive to specific
metal elements such as CoCr found
in femoral heads10
• Fracture toughness increased
150%, burst strength increased
160%, and four-point bending
strength improved 210% compared
with BIOLOX forte ceramic7, 10
• Alternative to a metal-on-metal
articulation for surgeons concerned
with delayed metal sensitivity due to
metal wear and metal ions
Designed for
Stable Cup Fixation
Full Hemispherical Design
The Maxera Cup is a familiar 180° full
hemisphere.
• Many surgeons are experienced in
implanting hemispherical cups.
Several currently available press-fit
cups feature this design, such as
Trilogy®, Converge®** and Continuum®
Acetabular Systems
• Maxera Cup instrumentation allows
surgeons to choose the desired
press-fit based on patient’s bone
quality
** N
ot commercially available outside the
United States and Japan.
Anti-rotation Fins Provide
Increased Rotational Stability
• Three sets of paired, anti-rotation fins
(6 fins total) are equally distributed
around the cup to provide increased
rotational stability8, 11
• To maximize the available surface
coating and reduce micromotion, the
area between the fins is also coated
with Ti-VPS (titanium vacuum plasma
spray)12
