Monolock Osteo Polyaxial Screw Fenestrated SQ is designed to provide enhanced fixation and controlled cement augmentation through its fenestrated screw design, which allows bone cement ejection to improve anchorage in compromised bone conditions. The screw features a specialized thread profile with double lead threads for cancellous bone engagement and four lead threads for cortical bone purchase, supporting strong fixation and efficient insertion. The polyaxial functionality allows flexible angulation for accurate rod alignment, and the system is available in multiple diameter options including 5.5 mm, 6.5 mm, and 7.0 mm with various length configurations to accommodate different anatomical and surgical requirements.
