1. A spinal implant comprising:
an upper body including an outer surface;
a lower body including an outer surface, a height dimension of the spinal implant being defined between the outer surface of the upper body and the outer surface of the lower body;
a first adjustment assembly disposed between the upper and lower bodies in a first region of the spinal implant, the first adjustment assembly being adjustably coupled to the upper and lower bodies so as to change the height dimension of the spinal implant in the first region upon actuation of the first adjustment assembly; and
a second adjustment assembly disposed between the upper and lower bodies in a second region of the spinal implant, the second adjustment assembly being adjustably coupled to the upper and lower bodies so as to change the height dimension of the spinal implant in the second region upon actuation of the second adjustment assembly, the first and second adjustment assemblies being independently actuatable from one another,
wherein the first adjustment assembly includes a ramp configured to slide transverse to the height dimension in response to actuation of the first adjustment assembly, so as to change the height dimension of the spinal implant in the first region, and wherein the second adjustment assembly operates in a different manner than the first adjustment assembly in response to actuation of the second adjustment assembly, so as to change the height dimension of the spinal implant in the second region.
