Solutions beyond fusion
With Ennovate® TLSP, we introduce an unprecedented modular platform that adapts to your needs and workflows. Empowered by Ennovate® PolyLock® and Ennovate® PentaCore®, surgical versatility and intraoperative experiences reach new heights, enabling for the best possible clinical outcome.
Surgical solutions
Let's dive into a situation you know. The patient is being prepared for surgery. Mentally, you go through every single step and detail. Everything is planned. The surgery is proceeding smoothly so far. And then – it's that moment you've been calculating in the back of your mind, the one that wants to challenge you.
0%
more control during spinal correction with Ennovate® PolyLock®
0%
less screw loosening thanks to Ennovate® PentaCore® [4], [10], [11]
0%
more long-term screw stability due to Ennovate® performance design [12]
Ennovate® TLSP PolyLock®
You know this situation just too well: the spinal correction is the next step and polyaxial pedicle screws have been placed. Do you really want to give up control during correction due to polyaxial head movements? [1-3]
Imagine being able to switch between the best of both worlds and switch between polyaxial and monoaxial functionality at any time during surgery. Embrace the possibility of true parallel compression/distraction, powerful reductions, and accurate spinal corrections.
“PolyLock® gives us the possibility of switching between the polyaxial and monoaxial screw at any time during the surgery, without the need for any further implants. This is a unique screw, which is useable, really useable, for perfect derotation maneuvers and curvature restoration, no matter if sequential or en-bloc. [17]”
Ennovate® TLSP PentaCore®
The growing number of patients with poor bone quality challenges the effective management and decision making in the event of spinal disorders. [4-5] Not an easy task, but what would you say if there is something that simplifies your decision making? Imagine working with a pedicle screw whose design is inspired by the anatomy and biomechanics of the vertebra, allowing anchorage along the entire screw. Empowered by Ennovate® PentaCore® our screw takes advantage of the viscoelastic behavior of the cancellous bone, enabling a tight form fit between bone and implant. [7-9]
“In our clinic we have a high number of elderly patients with osteoporosis, where we really appreciate the ease of use and the safe application of the cement, as well as the high intraoperative flexibility and versatility of the Ennovate® screws and the whole Ennovate® platform. [17]”
Ennovate® performance design
Do you know what happens to the screws post-operatively? Long-term stability is often taken for granted and rarely considered in detail, since it is a primary requirement and assumed that it is technically impossible to get more out of a screw. Because screws are just screws. Well, we do not see it that way! Our German engineers have design and technology in their DNA. The result is a screw that sets new biomechanical benchmarks.
Precision where it counts – The smart pressure mechanism enables toggle-free connection. This enables precise work in hands-free as well as navigated surgical steps.
The design reflects the natural shape of the pedicle and shows a larger thread diameter in the upper part of the screw. In combination with the Dual Core design, the large proximal flanks create pullout resistance. [12-14]
PentaCore® for voluminous anchorage in cancellous bone. Cylindrically shaped core for cortical bone compactation and stable anchorage. Plus 28% less tensile stress within the screw for improved long-term performance.[9,12,13]
The fenestrated screws can be used for the application of various fluids. In case of poor bone quality, the combination of slots and the PentaCore® allows for a unique form fit which is more stable against rotational force.
Smooth insertion of the self-tapping and self-centering thread – bone purchase and grip from the very first turn. Rounded, flat tip and quick-start thread allow improved bicortical anchorage of the screw. [12-14]
