Abstract

The present disclosure provides adjustable spinal devices, instruments for implanting the spinal devices, methods for adjusting the height and/or lordosis angles of the spinal devices and methods for implanting such devices. An adjustable spinal fusion device includes an upper plate having an outer surface for placement against a first vertebral body and a lower plate having an outer surface for placement against a second vertebral body. The device further includes a translation member configured to move longitudinally relative to the upper and lower plates to adjust an angle between the upper and lower plates. The translation member may include an angled surface or wedge for cooperating with a ramp on the device to pivot the proximal end of the upper endplate relative to the proximal end of the lower endplate and thereby adjust a distance between the distal ends of the endplates.
