Short-Term Outcomes of a Novel Non-Screw Based Expandable Posterior Interbody Fusion Cage

Abstract

Lumbar interbody fusion is a well-established surgical technique for treating various lumbar degenerative pathologies. Expandable cages have been introduced to allow for insertion via the confined access and to improve disc height restoration, though concerns about the stability of the screw-based cages in the expanded state remains a concern. This study aims to evaluate the short-term clinical and radiographic outcomes of a novel non-screw based expandable TLIF cage.
