EMPOWR Dual Mobility™

EMPOWR Dual Mobility™ is engineered for enhanced joint stability and helps reduce risks of dislocation by offering the largest assembled head for a given cup size1. Its robust locking mechanism aided by the uniquely designed dome peg and locking tabs helps in achieving a robust cup-liner engagement, which enhances corrosion resistance and helps build surgeon confidence.2 Liner installation is hassle-free and as easy as “rotate, drop, and lock”. These features, when combined with ONE tray instrumentation, provide a unique and efficient solution that a modern practice demands.

Empower Dual Mobility Surgical Technique - Step 1
1

Estimate acetabular
component size and position
with preoperative templates.

Empower Dual Mobility Surgical Technique - Step 2
2

Sequentially ream until good contact is
made with the host bone in the desired
position for the cup. Line-to-line
reaming is recommended. When soft
bone is encountered under reaming by
1mm may be necessary.

Empower Dual Mobility Surgical Technique - Step 3
3

Once the final cup size has been
determined, attach the cup implant
to the cup impactor handle and
impact into the acetabulum.

Empower Dual Mobility Surgical Technique - Step 4
4

If using a Cluster or Multi-Hole cup,
bone screws may now be drilled for
and implanted. The screw(s) must be
fully seated to ensure engagement
of the Dual Mobility metal liner.

Empower Dual Mobility Surgical Technique - Step 5
5

Gently introduce the dual mobility
metal liner into the cup and align
them by rotating the liner along the rim of the cup until the liner tabs drops
into the cup scallops. The liner is ready
to be impacted.

Empower Dual Mobility Surgical Technique - Step 6
6

Impact the metal liner with
the impactor taper-lock, using
appropriate force. Ensure the metal
liner is fully seated without being
canted or tilted.

7

Assemble the corresponding femoral
head trial with the desired offset
on the femoral stem trunnion and
reduce the joint to assess stability,
leg length, joint tension, and range
of motion. Adjust offset if necessary
and remove trial components once
satisfied.

Empower Dual Mobility Surgical Technique - Step 8
8

Perform back-table assembly of the
corresponding polyethylene bearing
and 28mm inner femoral head. Using
the assembly fixture, feel the initial
big “drop” for initial capture and then a
smaller “slip” to finish assembly. The
inner head must be able to articulate
freely inside the polyethylene bearing.

Empower Dual Mobility Surgical Technique - Step 9
9

Place the assembled implants on the
femoral stem trunnion and impact
with the head pusher to taperlock.
Ensure the head-neck taper
connection is secure.

Empower Dual Mobility Surgical Technique - Step 10
10

Perform final reduction of the joint
and assess stability, leg length, joint
tension and range of motion.
