Facilitator
Once the rod has been captured and reduced in the
polyaxial screw heads, compression and distraction
maneuvers can be accomplished.
Parallel Compression / Distraction
When using Correction Keys, engagement of the Poly Lock
will convert the polyaxial screw to a monoaxial implant
maintaining the position of the implant head while allowing
for translation of the pedicle screw along the rod.
After locking the outer portion of the Correction Key, it is
possible to apply parallel compression / distraction between
vertebral levels: this can be used to level the most proximal
and distal level of the construct relative to the patient
anatomy and additionally, medial-lateral correction when
applied across multiple levels.

Increasing Lordosis / Decreasing Kyphosis
Ensuring the head polyaxialty has not been locked, applying
compression between adjacent screws will decrease the
distance between the posterior elements, increasing lordosis /
decreasing kyphosis.

Increasing Kyphosis / Decreasing Lordosis
Ensuring the head polyaxialty has not been locked, applying
distraction between adjacent screws will increase the
distance between the posterior elements, increasing kyphosis
/ decreasing lordosis.
