DELTA™ Spinal Fusion System

• Wide Bone Screw Angulation:
• Industry leading 86 degree housing/bone screw angulation;
• No need for precise rod contouring;
• No need for precise screw placement;
• Screw placement in locations/positions otherwise prohibitive with traditional Mono and Poly-Axial Pedicle Screws;
• Double-Locking Compression Retaining Member:
• Secure rod/screw assembly interface which “locks” the rod into the poly-axial housing;
• Eliminates pre-mature loosening of the compression retaining member/rod/housing interface;
• Make possible segmental compression, distraction and de-rotation after placement/securing the poly-axial housing;
• Bi-Polar Cup Technology:
• Increases the bone screw/poly-axial housing interface;
• Increased assembly strength;
• Provides a “dual-axial” spherical points of rotation at the poly-axial/bone screw interface;
• Ability to secure the poly-axial housing prior to segmental compression, distraction and de-rotation:
• Offers advantage to the surgeon by allowing pre-placement and alignment of the poly-axial housing;
• The surgeon is able to “lock” the optimal housing placement before segmental compression, distraction and de-rotation;
• “Locking” the poly-axial housing before compression or distraction reduces inherent sheer-stress on the pedicle caused by compression or distraction;
