Abstract
Embodiments are directed to an expandable spacer for insertion between two adjacent bony structures or two adjacent joint surfaces, and more particularly relate to an expandable spacer for insertion into the void remaining in the intervertebral space. Embodiments may include an expandable spacer comprising a first endplate; a second endplate spaced from the first endplate; and one or more bags disposed between the first endplate and the second endplate that couple the first endplate to the second endplate. The one or more bags may be configured to receive a filler material to expand the expandable spacer from an initial position having a first height to an expanded position having a second height, wherein the second height is greater than the first height.
