The modifications included in this submission is the addition of Polyaxial LP Screws, and additional sizes of Polyaxial TTL U Screws, Polyaxial TTL High U-screw, Monoaxial TTL U Screws, Polyaxial Hemispherical Screws, MX Polyaxial Screws, MX Monaxial Screws - Closed and MX Monaxial Screws - Open.

Davantis/Antelys Vertebral Body Replacements are vertebral body replacements for use in the lumbar and thoracic spine (T4-L5) to replace a damaged, collapsed or unstable vertebral body due to tumor or trauma (i.e. fracture). These are not stand-alone devices, ISOBAR 06.2 Hemispherical Screws with Offset Clamps and Ø5.5 Rods must be utilized to enhance the stability of the reconstruction in skeletally mature patients following full or partial corpectomy.

The DAVANTIS/ANTELYS Vertebral Body Replacements are oval shaped. The interior of the spacers has three compartments to provide space for bone graft. The implanted in the vertical position. These components are available in various heights (9mm-75mm). The superior and inferior surfaces of these components have ridges to interface with the vertebral endplates to resist rotation. The body has a multitude of holes to allow additional impaction of bone graft. The DAVANTIS!ANTELYS components are fabricated from pure poly(ether ether ketone) (PEEK). This material closely matches the modulus of elasticity of cortical bone, improving the biomechanical interface and reducing the stress shielding effect. They are fully radio-translucent, which enables optimum follow-up with diagnostic imaging, as the interbody fusion progresses. Two metal wires at the opposite ends of the spacers allow radiological confirmation of the cage position post operatively.

The Scient'x Cement Restrictor is intended as a cement restrictor in orthopedic surgeries such as those involving the femoral canal and tibial plateau in hip stem and total knee replacement. This device is not intended for any spinal indications. The safety and effectiveness of this device when implanted in the spine have not been established.

The Scient'x Cement Restrictor is a hollow trapezoidal block with 1mm toothed serrations on opposite sides to prevent migration and has a threaded hole on the superior surface to attach an insertion tool. The parts are machined from PEEK that conforms to ASTM F2026-02. As peek is radiolucent gold wire radiographic markers inserted into small holes and serve as location and orientation markers for radiographs.

CO Vertebral Body Replacements are vertebral body replacements for use in the lumbar and thoracic spine (T1-L5) to replace a damaged, collapsed or unstable vertebral body due to tumor or trauma (i.e. fracture). These are not stand-alone devices, ISOBAR Ø6.2 Hemispherical Screws with Offset Clamps and Ø5.5 Rods must be utilized to enhance the stability of the reconstruction in skeletally mature patients following full or partial corpectomy.

The CO Vertebral Body Replacements are rectangular shaped in pairs for full corpectomy or individually when only a portion of the vertebral body is resected. The interior of the spacers is open to provide space for bone graft. The implant is always implanted in the vertical position. These components are available in various heights (7mm-150mm) and cross sections to accommodate the variability of patient size, anatomic variation, and the size of the vertebral body defect. The superior and inferior surfaces of these components have ridges to interface with the vertebral endplates to resist rotation and migration. The body has a multitude of holes to allow additional impaction of bone graft. The CO components are fabricated from pure poly(ether cther ketone) (PEEK). This material closely matches the modulus of elastical bone, improving the biomechanical interface and reducing the stress shielding effect. They are fully radio-translucent, which enables optimum follow-up with diagnostic imaging, as the interbody fusion progresses. I wo metal wires at the opposite cads of the spacers allow radiological confirmation of the cage position post operatively.

The modification included in this submission is the addition of polyaxial hemispherical screws. These screws function in the same manner as the previously cleared hemispherical screws by insertion into the pedicle then placing an offset clamp over the screw with a rod that has been loaded into the clamp. A nut is them placed on the screw and tightened to secure the assembly. The new polyaxial screw allows the proximal portion of the screw to angulate in order to ease the assembly of the rod loaded clamps onto multiple screws that may not be axially aligned.
