1. A method of separating bones of a joint, comprising:
inserting a spacer between bones of the joint, the spacer including:
first and second endplates; and
an activation assembly including a cam frame having first and second sides and disposed between the first and second endplates, each side having at least one cam slot, the activation assembly further including a cam pin slidably received in the respective cam slot,
translating the cam frame along a longitudinal axis of the spacer, translation of the cam frame causing the cam pins to slide within the cam slots which in turn causes one of the endplates to move apart from the other endplate to change a height of the spacer.
