The DELTA™ Spinal Fusion System employs unique proprietary technological advancements in poly-axial screw design which aids the surgeon’s placement of the screw, ease of construct installation and ultimately positive surgical outcome. All components are made of Ti6AI4V ELI, a Titanium based alloy, which complies with ASTM F136-98
Features:
- 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;
