Assessment of intra-operative impact durability of additively manufactured mock lumbar intervertebral body fusion devices.

Abstract

Spinal interbody fusion devices (IBFD) are commonly used to treat various spinal pathologies. Additive Manufacturing (AM) has been used to incorporate lattice structures into IBFD designs, intended to facilitate bony in-growth and reduce stress shielding. However, there is concern with IBFDs failing intra-operatively based on the medical device adverse event reporting to FDA, in which such failures were reported for both AM titanium as well as traditional PEEK IBFDs. This study aims to develop a
