About this product

Division: International
Category: Anterior Lumbar Interbody Fusion (ALIF)

The SYNFIX™-LR System is a comprehensive set of implants and instruments designed for stand-alone anterior stabilisation of the lumbar spine from L2 to S1.

The SYNFIX-LR implant is a standalone ALIF device that incorporates the benefits of an anterior plate and a radiolucent interbody spacer. The design creates a zero-profile construct and includes four locking screws that provide anterior fixation and stability.


Features & Benefits


  Features Benefits
Stand-alone ALIF implant
  • Biomechanically equivalent to a spacer with pedicle screws1
  • PEEK spacer provides modulus of elasticity similar to cortical bone
  • Titanium plate with locking screws provide stable fixation
Zero-profile construct
  • Spacer and plate fit completely within the disc space
Anatomic shape
  • The SYNFIX-LR is convex to match the anatomy of the disc space
  • Two footprints, two lordotic angles, and five heights are offered to accommodate individual patient anatomy
Screw and plate fixation
  • One-step conical locking mechanism eliminates need for blocking plate
  • Locking screws provide stability and load transfer near the cortex of the vertebral body
  • Four locking screws diverge to form a fixed-angle construct that creates a wedge of bone for fixation
  • Self-tapping cortical threads allow largest possible core diameter for maximum fixation
