1. A vertebral spacer implant comprising:
a vertebral spacer body that is configured to interpose between two vertebra in a vertebral column; two connector flanges disposed on a surface of the vertebral spacer body; a connector mechanism receiving portion at least partially defined by the two connector flanges and the vertebral spacer body; a pivot element receiving throughhole defined by the two connector flanges; an insertion rod retention portion defined by the vertebral spacer body; and an insertion rod configured to engage the insertion rod retention portion, the insertion rod comprising a retention pin engaging retention hole configured to allow the insertion rod to apply a force to a vertebral spacer in either tension or compression, wherein:
the two connector flanges are substantially parallel;the pivot element receiving throughhole defines a rotation axis substantially perpendicular to the two connector flanges; andthe connector mechanism receiving portion is configured to allow the vertebral spacer body to pivot about the rotation axis.
