Overview
Brief Summary
The primary objective of this pilot study is to determine the precision of post-operative radiostereometric measurements for the assessment of lumbar spinal fusion. This study will also determine the potential for RSA as a more precise and accurate means for assessment of lumbar spinal fusion and diagnosis of pseudarthrosis.

Outcomes
Primary Outcomes
Intervertebral motion post-op lumbar fusion
Time Frame: 2 years
The purpose of this radiostereometric analysis (RSA) evaluation is to measure relative intervertebral motion in lumbar spinal fusions. Two RSA loading provocation protocols will be employed in this study; sitting and supine extension. Both loading protocols will be compard to a standard supine position which is used as an unloaded baseline protocol. Induced intervetebral motion sets will be calculated between the two loaded states, sitting and supine extension, and the unloaded state. The RSA micromotion results will be calculated and reported as translations and rotations about the three anatomic axes, maximum total point motion (MTPM) will be calculated as well.
