Biomechanical comparison of anterior lumbar interbody fusion: stand-alone interbody cage versus interbody cage with pedicle screw fixation - a finite element analysis
BACKGROUND Anterior lumbar interbody fusion (ALIF) followed by pedicle screw fixation (PSF) is used to restore the height of the intervertebral disc and provide stability. Recently, stand-alone interbody cage with anterior fixation has been introduced, which eliminates the need for posterior surgery. We compared the biomechanics of the stand-alone interbody cage to that of the interbody cage wi...
متن کاملEvaluation of a Novel PEEK Titanium Composite (PTC) Interbody Cage in an Ovine Lumbar Interbody Fusion
INTRODUCTION: The majority of interbody devices for spine fusion are PEEK. Other interbody devices use a rough 2D titanium surface or full porous titanium or tantalum cores, which have been shown in-vitro and in-vivo to promote osteoinduction and osteointegration, respectively. Combining the increased osteogenic environment that titanium provides and the minimized subsidence and radiolucency fr...

STUDY DESIGN Controlled laboratory study. OBJECTIVE To evaluate the biomechanical characteristics of a new expandable interbody cage in single-segment posterior lumbar interbody fusion (PLIF) using cadaveric lumbar spines. SUMMARY OF BACKGROUND DATA One of the popular methods of treating lumbar spine pathologies involves a posterior lumbar interbody fusion using bilateral interbody nonexpan...
متن کاملPosterior Lumbar Interbody Fusion Using an Unilateral Cage: A Prospective Study of Clinical Outcome and Stability
OBJECTIVE The purpose of this study was to evaluate the clinical and radiological results of instrumented posterior lumbar interbody fusion (PLIF) using an unilateral cage. METHODS Seventeen patients with unilateral radiculopathy who underwent bilateral percutaneous screw fixation with a single fusion cage inserted on the symptomatic side for treatment of focal degenerative lumbar spine disea...
