1. A method of treating a patient having a spinal pathology within a functional spinal unit (FSU) having an upper vertebra, a lower vertebra, and an intervertebral disc therebetween, the method comprising:
- damaging an anterior longitudinal ligament (ALL) of the patient, thereby increasing the range of motion of the FSU in extension,inserting an interbody device into a void between the upper and lower vertebrae, the interbody device comprising;
a) an upper portion having an upper surface adapted for bearing against the upper vertebra and having teeth extending therefrom for gripping the upper vertebra,b) a lower portion having a lower surface adapted for bearing against the lower vertebra and having teeth extending therefrom for gripping the lower vertebra, andc) a wall connecting the upper and lower portions,wherein the upper and lower portions of the device are non-parallel.

19. An intervertebral device, comprising:
-
a) an upper portion having an upper surface adapted for bearing against an upper vertebra and having teeth extending therefrom for gripping the upper vertebra, b) a lower portion having a lower surface adapted for bearing against a lower vertebra and having teeth extending therefrom for gripping the lower vertebra, wherein the upper and lower portions of the device extend in a non-parallel manner in a first direction, c) a wall connecting the upper and lower portions, d) an upper extension extending above the upper surface and having at least one transverse hole having an upper bone fastener received therein, wherein the upper bone fastener has a longitudinal axis extending substantially transversely from the first direction, and e) a lower extension extending beneath the lower surface and having at least one transverse hole having a lower bone fastener received therein, wherein the lower bone fastener has a longitudinal axis extending substantially transversely from the first direction. - View Dependent Claims (20, 21, 22, 23, 24, 25)

26. An intervertebral device, comprising:
-
a) an upper portion having an upper surface adapted for bearing against an upper vertebra and having teeth extending therefrom for gripping the upper vertebra, b) a lower portion having a lower surface adapted for bearing against a lower vertebra and having teeth extending therefrom for gripping the lower vertebra, c) a wall connecting the upper and lower portions, d) an upper extension extending above the upper surface and having at least one transverse hole having an upper bone fastener received therein, and e) a lower extension extending beneath the lower surface and having at least one transverse hole having a lower bone fastener received therein, the device defining a height between a posterior end of the upper surface of the upper portion and a posterior end of the lower surface of the lower portion, wherein the height is adjustable under an axial load. - View Dependent Claims (27, 28, 29)
