73% Improvement in VAS Pain with Novel Expandable Cage - Video
Watch our Master Class 'Restoring Lumbar Lordosis with an Expandable and Articulating Interbody: Two-year clinical and radiographic outcomes of a prospective study on segmental lordosis and fusion'. This video discusses 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. Weinstein discusses his two-year postoperative results – highlighting segmental lordosis correction and pelvic parameters, fusion status, and outcome measures including visual analog scale (VAS) back and leg pain, and Oswestry Disability Index (ODI). Learning Points: • 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 transformational 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.
