Abstract
Background Data: The incidence of interbody cage subsidence in OLIF is 8–9.5%. It occurs mainly secondary to osteoporosis or endplate damage during disc space clearance. An anatomical study correlated the surface area contact and position between the cage and the disc space to the incidence of subsidence. Studies have concentrated on the optimal place in the disc space to place the cage to obtain less incidence of subsidence, as it was reported that the central part of the disc space, called the epiphyseal ring, is the toughest part. Subsidence is usually noted in the superior vertebral endplate. Until now, there has been a lack of data regarding the main cause of subsidence.
