Medical device company Life Spine has published the results of a study examining the effects of its ProLift expandable spacer system in minimally invasive transforaminal lumbar spinal fusion.
The study examined patient reported outcomes, sagittal alignment and restoration of disc height and foraminal height comparative to static interbody cage, according to an April 18 press release.
The study determined a significant improvement in patient-reported outcomes and radiographic measures, which were sustained through the two-year visits required by the study.
When compared to static interbody implants, patients with the ProLift expandable spacer system saw an 85 percent increase in anterior disc height, a 190 percent increase in posterior disc height, a 113 percent increase in average disc height and a 45 percent increase in foraminal height.
