Set Screw Insertion and Rod Capture
The Correction Key and Unitized Set Screw are available
in the EXPEDIUM VERSE System. The Correction Key
(1997-21-000) allows for the independent locking of the
polyaxial head and the rod. Consequently, the implant
can be converted from a polyaxial screw to a monoaxial
screw anywhere within the implant’s range of motion
while still allowing the rod to move below the Correction
Key. This affords the surgeon the ease of rod capture
without compromising control over the vertebral body.
Converting the implant to a monoaxial screw facilitates
parallel compression and distraction and derotation
maneuvers. If dual stage locking is not required, the
Unitized Set Screw (1997-21-001) is also provided for
one-step locking of the screw head and rod. For insertion of
the Correction Key, the Key Inserter/Tightener must be
assembled to the Pencil Handle. For insertion of the
Unitized Set Screw, the X25 Inserter/Tightener must be
assembled to the Pencil Handle.
NOTE:
The diameter of the Pencil Handle has been
designed with the intent to enhance tactile feedback
during Correction Key or Unitized Set Screw
engagement and during reduction while inducing a
technique which utilizes staged reduction across multiple
operative levels.
