Pre OP images, sagittal & axial views at the levels of the planned implant placements
Intra OP
Access and K-wires placement
Pedicle screws insertion
Posterior fixation with Neo Pedicle Screw System™
Totally 8 pedicle screws were placed over the levels T8 – L1
- T8 – 2 x Ø5.0x45 mm polyaxial
- T9 – 2 x Ø6.0x50 mm polyaxial
- T11 – 2 x Ø6.0x50 mm polyaxial
- L1 – 2 x Ø7.0x45 mm polyaxial
Video is showing all steps using Neo ADVISE™ fixation module in the left side of the spine
