Claim 21:
22. The method for implant sizing of claim 21, further comprising:
selecting a second implant size based on the indication that the selected implant size is incorrect;
preparing the trialing instrument including coupling a second pressure sensitive trial implant to the distal end of the elongate shaft portion, wherein the second pressure sensitive trial implant corresponds to the second implant size, the second pressure sensitive trial implant having a second, different non-adjustable thickness between a second superior end plate exterior surface and a second separate inferior end plate exterior surface, the second pressure sensitive trial implant including one or more second lateral side surfaces between the second superior end plate exterior surface and the second inferior end plate exterior surface, wherein at least one of the second superior end plate exterior surface and the second inferior end plate exterior surface of the second pressure sensitive trial implant is covered in a second pressure sensitive film, and wherein the second pressure sensitive film is further disposed on at least a portion of the one or more second lateral side surfaces;
trialing the second pressure sensitive trial implant; and
determining whether the second implant size is correct based at least in part on comparing a state of the second pressure sensitive film disposed on at least one of the second superior end plate exterior surface and the second inferior end plate exterior surface of the second pressure sensitive trial implant to the known standard.
