Background: A successful intervertebral fusion requires biomechanical stability created by
the structural support of the interbody device and loading of the bone graft material to …

Introduction: The objectives of this paper were to identify and explain specific design factors
for lumbar interbody fusion (IBF) devices that can influence bone exchange and stability at …

Interbody fusion cages are routinely implanted during spinal fusion procedures to facilitate
arthrodesis of a degenerated or unstable vertebral segment. Current cages are most …

Abstract Background Context Various surface modifications, often incorporating roughened
or porous surfaces, have recently been introduced to enhance osseointegration of interbody …
