What's being measured
Primary outcomes are the specific endpoints the trial is designed to prove or disprove.
-
Brantigan-Steffee-Frasier (BSF) Fusion Scale
Time frame: Six months following procedure
Graded radiographic evaluation of ossification and/or pseudarthrosis between vertebrae. The evaluation applies a three-level scale of fusion success: BSF-1: Radiographical pseudarthrosis BSF-2: Radiographical locked pseudarthrosis BSF-3: Radiographical fusion Radiographic Success: Radiographic success is defined by radiographical fusion (BSF-3) presenting bone bridges within at least half of the
Sponsor's own description
The objective of this single site, randomized controlled trial is to assess and compare radiographic and clinical outcomes in patients who are to undergo lumbar interbody fusion procedures (TLIF), supplemented with pedicle screw instrumentation, using one of the following interventions: 1. Porous titanium cages 2. Non-porous titanium-coated poly-ether-ether-ketone (PEEK) cages.
