ISSYS LP

---

The patented design of ISSYS LP is the next generation pedicle screw system.  The highly advanced system was designed to provide patients with a stronger construct that better promotes fusion while enhancing the instrumentation to offer surgeons tools that are more effective during implantation.  ISSYS LP’s unique design allows the pedicle screw to be fully seated in the bone while maintaining full polyaxial motion creating improved resistance to fishtailing or screw movement.  The ISSYS LP pedicle screw was also designed to accommodate three rod sizes due to the unparalled saddle pin feature. 

Features and Benefits

ISSYS LP Pedicle Screw System features:

» Zero Moment Screw:  Center of rotation is at the bone level to better withstand forces on the construct reducing the risk of loosening and breakage.

» Reduced Risk of Fishtailing:  Fully seated screw provides better bone to screw interface, while maintaining polyaxial motion of the screw head.  Ideal for compromised bone.

» 63% Greater Resistance to Load Forces:  Fully seated screws withstand more load across the pedicle when compared to proud screws.  Proud screws must withstand much higher stresses at the screw-bone interface increasing the risk of breakage or loosening.

» 60% Greater Medial/Lateral Translation:  With the screw fully seated, ISSYS LP pedicle screws have 3.2mm of translation per side requiring less rod bending that weakens titanium rods.

» Controlled Bone Screw Placement:  The screwdriver holds the bone screw in a toggle free grip allowing the surgeon to drive the screw straight into the bone.

» System Versatility:  Unique saddle pin design allows three rod sizes to be used in one system while reducing the risk of rod notching.

» Optimal Screw Profile:  Designed to withstand the higher pullout forces while inserting 40% faster than standard bone screws.

» Low Profile:  Allows close proximity to the screw placement.


Indications for Use:
