FENESTRATED PEDICLE SCREW
Not FDA Approved
Perforated Screw Shank
The perforations allow for cement injection through the screw shank into the vertebral body to enhance screw purchase in patients with diminished bone quality.
Homogeneous Cement Delivery
Perforations are located on the screw shank to minimize taping effect during screw insertion. 3×3 perforations allow homogeneous cement delivery.
A dedicated cement filler PP has been designed with a high precision interface, and a good fitting area, with the screw. Safe cement delivery, and an efficient connection to PP screws, is ensured.
Safe Cement Injection
The internal geometry was designed according to the principle of fluids mechanics to allow for cement to flow through the perforations and not through the endtip.
