Claim Text:
1. A milling guide for use with an instrument system for preparing an intervertebral space defined by two adjacent vertebrae, the instrument system including a trial head sized to be received in the intervertebral space, the milling guide comprising: a milling guide body defining a proximal end and a distal end that is spaced from the proximal end along a first direction, the milling guide configured to be supported relative to the trial head; a chamber coupled to the milling guide body, the chamber being elongate along the first direction; and a pivot element coupled to the milling guide body and defining a channel that extends through the pivot element such that the channel is configured to at least partially receive a tool for preparing at least one of the two adjacent vertebrae, the pivot element configured to pivot relative to the milling guide body about a pivot axis that extends through both the milling guide body and the channel in a second direction that is substantially transverse to the first direction, wherein the pivot element is configured to pivot about the pivot axis when 1) the milling guide is supported relative to the trial head, and 2) when the trial head is received in the intervertebral space.
