AVS UniLIF

PEEK Spacer

Posterior lumbar PEEK spacer designed for both bilateral PLIF and oblique TLIF surgical approaches

AVS UniLIF PEEK Spacer

We uniquely designed these posterior lumbar PEEK spacers to either have standard lengths for bilateral PLIF approaches or longer lengths with obliquely oriented lordotic angles for unilateral TLIF approaches. The latter option allows you to insert a single spacer diagonally across the disc space while still restoring lordosis in the appropriate anterior-posterior plane.

  • Available in a variety of lengths, heights and lordotic angles to adapt to a variety of patient anatomies 

  • Large internal chamber for the bone graft material of your choice

  • Serrations on the superior and inferior surfaces for multi-directional fixation

  • Ergonomically shaped anterior edges and flat posterior edges 

  • Radiopaque tantalum markers for visualization in radiographic images
