摘要：
A spinal interbody device includes a base link comprising a first end and a second end, the base link including a cutout extending through the base link between the first end and the second end； a linkage including a first link having a first end coupled to the first end of the base link and a second end, the first link including a first aperture extending through the first link and defining a first longitudinal axis； and a second link having a first end coupled to the second end of the first link and a second end coupled to the second end of the base link, the second link including a second aperture extending through the second link and defining a second longitudinal axis. The base link and the first and second links define top and bottom surfaces configured to engage adjacent portions of bone, and first and second sides extending between the top and bottom surfaces. When the linkage is movable relative to the base link between a collapsed position and an expanded position, wherein when in the expanded position, an unobstructed line of sight is provided through the cutout and the first aperture along the first longitudinal axis and through the cutout and the second aperture along the second longitudinal axis.
