摘要:
A variable lordotic interbody spacer including a face plate, superior and inferior endplates coupled to the face plate via a hinge, an actuation frame between the endplates, and an actuation screw. The face plate includes actuation and stabilizer channels. Each of the endplates has endplate arms coupled by an endplate base, and includes actuation ramp recesses. The actuation frame includes frame arms coupled by a frame base in a generally U-shaped configuration, each actuation frame arm having a stabilizer feature passing through a corresponding stabilizer channel and having actuation ramp pins fitted to a corresponding ramp recesses. The actuation screw passes through the actuation channel, with a head retained at the front surface and a threaded end coupled to the actuation frame. When operated, the actuation screw moves the actuation frame between the superior endplate and the inferior endplate to adjust an angle therebetween.
