Abstract
A spinal interbody device includes a base link having a first end and a 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, 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 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. The device further includes at least one radiographic element provided in at least one of the first link and the second link and positioned such that the radiographic element provides an indication of a degree of expansion of the device when the device is imaged from one of the first side and the second side of the device.
