At all Z-Pedicle Screws the Ini (Set Screw) is already pre-assembled in the long reduction thread. They are cannulated, fenestrated, in different diameters color coded and in various lengths as well as axialities sterile packaged available. Due to its unique tip as well as thread design, they are self-drilling and self-tapping. The multi-conical double thread design offers a maximum of stability and pullout strength and allows quick insertion of the Z-Pedicle Screw.
Between the implant and the lengthening shaft is a rigid connection which will be separated with an instrument. For this reason, the surgical correction of spondylolisthesis, reposition in fracture- and the derotation in deformity treatments can be achieved directly together with the innovative screw design and the long reduction thread including the pre-assembled Ini without any additional instruments.
If required a controlled cement augmentation is possible with the use of the Bone Cement Filler Cannula directly through the Screwdriver Pedicle Screw.
