FLX implants include a solid exoskeleton for added strength, along with a proprietary lattice scaffold designed to have a stiffness similar to bone. Reduced device stiffness is known to minimize stress-shielding and enhance the fusion process.

FLX implants include porous radiolucent sections with optimized density to reduce imaging artifacts—enhancing intra-operative visualization & post-operative fusion assessment compared to solid titanium implants.

FLX implants include a FUSE-THRU™ osteoconductive trabecular scaffold, bioengineered to allow the potential for bony on-growth and in-growth throughout the implant. This unique porous structure contains micro, macro, and nano structural characteristics designed to promote the fusion healing process by influencing cellular events related to the production of new bone.

ANATOMIC design

• Multiple Footprints
• Bullet Nose
• Large Graft Area
• Clear Visualization

Multiple Footprints

Multiple footprints for optimal endplate contact.

• Lengths of 45, 50 & 55mm
• Heights of 8, 10, 12, & 14mm
• Lordosis of 0° & 12°
• Widths of 18 & 22mm

Bullet Nose

Eases insertion, particularly when osteophytes are present.

Optimized, Open Graft Window to Promote Fusion Throughout

Increases opportunities for fusion through the implant.

• Large central graft window with concave graft containment cavity
• No center rail to obstruct fusion mass
• Proprietary FUSE-THRU™ lattice to enable the potential for ongrowth, in-growth, and thru-growth

Clear Visualization

• Alignment hole and crisp edges indicate alignment on A/P and lateral images
• FUSE-THRU™ lattice enables post-operative visualization of fusion mass

proven STALIF TECHNOLOGY

• No Profile^®
• Horizontal Inclination
• Midline Convergence
• Anti Back-Out Screws

STALIF No Profile^® Design

• Eliminates profile of plate, allowing for optimal load transfer within the vertebral segment
• Spares tissue with smaller surgical envelope to insert implant and integrated fixation
• Simplifies surgical technique to implant device

Horizontal Inclination

STALIF L™ screws are angled and biomechanically designed to direct axial forces along the long axis of the screws—significantly reducing bending moments and preventing de-rotation of the screw and / or screw back- out.

Midline Convergence

Centinel’s converging screw design and angles are biomechanically more resistant to screw backout compared to parallel screws. Additionally, midline convergence angles are designed to provide a more secure interbody construct.

Anti Back-Out^® Screws

STALIF cancellous lag screws are designed with an Anti Back-Out (ABO^®) retention feature—utilizing a titanium split-ring for an added layer of security.

The gold standard in minimally-invasive lateral fixation, STALIF L FLX maximizes opportunities for fusion by providing No Profile, intradiscal, integrated compressive lag fixation.
