IMPLANT DESIGN
The EXPEDIUM VERSE System represents the next “verse”
in posterior fixation. The EXPEDIUM VERSE Pedicle Screw
combines three proven technologies into one versatile implant.
Benefiting from the clinically proven design of the EXPEDIUM
5.5 and EXPEDIUM Favored Angle Screw Systems, each
pedicle screw component and feature has been scrutinized
and refined. The result is an implant which provides the
features of polyaxial, monoaxial, and side loading screw
technologies within a single screw type.
The “hypermobility” of the polyaxial head in combination
with 17mm of reduction provides the surgeon with the
tools necessary to capture the rod during complex spine
deformity procedures while obviating the need for complex
reduction instrumentation.
The pedicle screw is available in two versions. The Polyaxial
Screw incorporates the EXPEDIUM double-lead, solid shank
which has more than the years of clinical use globally. The
Fenestrated Cortical Fix Polyaxial Screw is designed to meet the
needs of challenging cases, building upon the feature set of
the Polyaxial Screw and adding a fully cannulated Cortical Fix
thread form with fenestrations. The Cortical Fix thread form
doubles the number of contact points within the pedicle and
increases the resistance to pull out*, ultimately enhancing
fixation within the pedicle. If more fixation is required, the
fenestrated tip of the Fenestrated Cortical Fix Polyaxial Screw
enables cement augmentation.
Using the EXPEDIUM VERSE System as a standalone system
provides reduction capabilities at each operative level,
accommodating techniques which promote the distribution
of correction forces. The result is a reduction of stresses at
the bone screw interface and a decrease in the potential for
intraoperative screw migration.

The Correction Key adds independent polyaxial head and rod
locking, providing intraoperative polyaxial to monoaxial screw
conversion at any time during the procedure and at any
location within the polyaxial head’s range of motion.

With the
EXPEDIUM VERSE Pedicle Screw, the implant is a polyaxial
screw during rod capture when mobility is required and a
monoaxial screw when correction forces need to be applied.
The EXPEDIUM VERSE Unitized Set Screw provides one-step
locking of the polyaxial head and rod should independent
locking not be required.
The result is a versatile system which enables surgeons to
leverage their technique when correcting spinal deformity
with fewer implant types and instruments while delivering a
more predictable intraoperative experience.
