1. A system for use during a surgical procedure on a patient, the system comprising:
(a) an implant having a modular cage and a shim with a cage tool-holding feature, an upper bracket, and a lower bracket, the modular cage including four modules:
(i) a first endplate adapted to press against anatomical structures of the patient,
(ii) a second endplate adapted to press against opposing anatomical structures of the patient,
(iii) a body with a top surface on which the first endplate is positioned and a first track extending along more than one side of the body, wherein the first track engages the upper bracket of the shim and the first track guides the shim into engagement with the modular cage, and
(iv) a column with a bottom surface on which the second endplate is positioned, a second track extending along an anterior side of the column and one or more lateral sides of the column, wherein the second track which engages the lower bracket of the shim and guides the shim into engagement with the modular cage, and at least one leg over which the body slides so that the at least one leg is contained at least partially within the body, and wherein the second track comprises a flange that extends continuously along at least the anterior side of the body, and
(b) a tool having an expander and an inserter, the tool engaging the cage tool-holding feature on the modular cage and adapted to position the modular cage at a surgical site within the patient, the expander sliding the body along the at least one leg to separate the body from the column in situ and thereby define the height of the implant, and the inserter positioning the shim between the body and the column,
wherein the height of the implant can be adjusted in situ to any number of possible heights between a starting height where the body is fully seated on the column and an upper limit where the body exceeds the height of the at least one leg, and the shim when positioned between the body and the column fixes the distance between the body and the column.
