Expandable posterior lumbar interbody cages: Results of a long-term study on segmental lordosis and fusion

Tuesday, September 15th, 2020 | 11:00 am - 12:00 pm CT

This webinar will discuss a prospective, single-arm, single-center study evaluating the sagittal correction achieved in the lumbar spine using a novel articulating and expandable interbody device capable of 15 degrees of lordotic expansion through a posterior surgical approach. Dr. Marc Weinstein will discuss his one-year postoperative results — highlighting segmental lordosis correction and pelvic parameters, fusion status and outcome measures including visual analog scale back and leg pain, and Oswestry Disability Index.

In this webinar, you'll learn:

  • Excellent clinical results can be achieved using an articulating and expandable posterior lumbar cage with a significant reduction in pain and disability.
  • Expandable cages implanted via a transforaminal approach may achieve and sustain greater improvement in segmental lordosis than static TLIFs.
  • Articulating cages can create greater effective cage size, improving endplate contact, reducing subsidence and providing a more anatomic fit.
