THE EFFECTS OF ANTERIOR DISCECTOMY AND INTERPOSITION AL IMPLANT UPON LUMBAR MOTION SEGMENT STABILITY

The cadaver spine motion segment behavior under torsional load was evaluated with the disc intact, with partial anterior discectomy and with spacer insertion. The results of this study explain how anterior lumbar discectomy and interbody fusion (ALIF) affects the torsional stability of the motion segment. The pseudarthrosis rate of the anterior lumbar discectomy and interbody fusion (ALIF)...

Adjacent Segment Motion After Lumbar Fusion

t I I Study Design. For in vitro studies, there is no basis t for choosing a "load control study" over a "displace: ment control" study. This study qualitatively compared f results from in vitro and in vivo tests, allowing the au€ : thors to address the experimental assumptions that in vitro testing contributes to the understanding of the in vivo condition. Objectives. To compare motion changes...

Interbody device endplate engagement effects on motion segment biomechanics.

BACKGROUND CONTEXT Stand-alone nonbiologic interbody fusion devices for the lumbar spine have been used for interbody fusion since the early 1990s. However, most devices lack the stability found in clinically successful circumferential fusion constructs. Stability results from cage geometry and device/vertebral endplate interface integrity. To date, there has not been a published comparative bi...
