Posterior Thoracolumbar Fixation

Tiger Deformity Fixation

PEDICLE SCREWS (continued)

UNI-PLANAR

The uni-planar pedicle screws
allow motion in the cephalad
to caudal direction while
restricting motion in the medial
to lateral direction

The size range is:

  • 4.5MM Diameter: 25MM – 45MM
  • 5.5MM Diameter: 25MM ~ 45MM
  • 6.5MM Diameter: 25MM ~ 45MM
  • 7.5MM Diameter: 25MM ~ 50MM

FRACTURE

The fracture pedicle screws
allow motion in the medial to lateral direction while restricting motion in the cephalad to caudal direction.

The size range is:

  • 4.5MM Diameter: 25MM – 55MM
  • 5.5MM Diameter: 25MM – 55MM
  • 6.5MM Diameter: 35MM – 55MM

UNI-REDUCTION

The uni-reduction pedicle screws have the same functionality as the uni-planar screws with the addition of reduction tabs.

The size range is:

  • 4.5MM Diameter: 25MM – 45MM
  • 5.5MM Diameter: 25MM – 45MM
  • 6.5MM Diameter: 25MM – 45MM
  • 7.5MM Diameter: 25MM – 50MM

CANNULATED OPEN

The cannulated open screws are poly-axial and allow for 360° of motion up to 30° angle each direction for the smaller diameter screws and ~21° each direction for larger diameter screws.

The size range is:

  • 5.5MM Diameter: 25MM-55MM
  • 6.5MM Diameter: 35MM-55MM
  • 7.5MM Diameter: 35MM-55MM
CANNULATED OPEN
SCREW
DUAL/QUAD

The Dual/Quad lead pedicle screws maintain a cortical style screw proximally that transition into a more cancellous type screw distally in order to obtain more purchase and increase pullout strength.

The size range is:

  • 5.5MM Diameter: 30MM – 55MM
  • 6.5MM Diameter: 35MM – 55MM
  • 7.5MM Diameter: 35MM – 55MM

HOOKS

Many hook options are available in the Tiger Deformity set. These hooks are designed to work with specific posterior anatomy such as the pedicle, lamina, or transverse process.
The surgeon should choose the appropriate hook based on the patient’s anatomy, the type of deformity, and method(s) of correction used.

PEDICLE SCREWS

POLY-AXIAL

The poly-axial pedicle screws allow for 360° of motion at up to ~30° angle each direction for the smaller diameter screws and ~21° each direction for the larger diameter screws.

The size range is:

  • 5.5MM Diameter: 25MM – 55MM
  • 6.5MM Diameter: 25MM – 55MM
  • 7.5MM Diameter: 35MM – 120MM

POLY-AXIAL REDUCTION

The poly-axial reduction pedicle screws have extended tabs on the tulip head aiding in the reduction of the rod.

The size range is:

  • 5.5MM Diameter: 25MM – 55MM
  • 6.5MM Diameter: 35MM – 55MM
  • 7.5MM Diameter: 35MM – 55MM

PEDICLE SCREW
POLY-AXIAL CLOSED TULIP HEAD

The closed tulip head poly-axial pedicle screws allow for additional strength by adding material to the top of the tulip head of screws used for iliac fixation.

The size range is:

  • 7.5MM Diameter: 60MM – 120MM
  • 8.5MM Diameter: 60MM – 120MM
  • 9.5MM Diameter: 60MM – 120MM
  • 10.5MM Diameter: 60MM – 120MM
POLY-AXIAL CLOSED TULIP HEAD
PEDICLE SCREWS
MONO-AXIAL

The mono-axial pedicle screws are fixed screws allowing for no motion.

The size range is:

  • 5.5MM Diameter: 25MM – 55MM
  • 6.5MM Diameter: 35MM – 55MM
  • 7.5MM Diameter: 35MM – 55MM
