Background: There is an absence of work on vertebral endplate response to peripheral
loading following disc removal and interbody placement. Endplate deflection into the …

Objective. To investigate stresses in cage type interbody fusion systems during compressive
loading. Design. The study uses finite element methods to investigate predicted stresses …

This study simulated the effects of inter-vertebral disc degeneration and bone density
distribution on the structural stiffness and strength provided by inter-vertebral fusion. Based …

BACKGROUND CONTEXT: Stand-alone nonbiologic interbody fusion devices for the lumbar
spine have been used for interbody fusion since the early 1990s. However, most devices …

Study Design: Calf and human cadaveric spines were used to determine motion segment
stiffness and laxity after implantation of threaded inserts (the Ray Threaded Fusion Cage …

Background: Expandable cages have gone through several iterations since they first
appeared on the market in the early 2000s. Their development was prompted by some …

How stiffness and strength of the human lumbar endplate vary with location, spinal level,
and its correlation with MRI findings of lumbar degeneration, has not been reported in detail …

BACKGROUND CONTEXT Expandable interbody fusion cages have been developed to
improve the ability to restore disc height and segmental lordosis. However, expandable …

Background: Expandable cages that allow for bidirectional expansion, in both height and
width, may offer benefits over traditional expandable cages or static cages. Effective stiffness …

Abstract Background Context In the lumbar spine, end plate preparation for the interbody
fusion cages may critically affect the cage's long-term performance. This study investigated …
