摘要： An implantable prosthesis (10) is described having a pair of opposed shells (20 & 40) and a central body (60) disposed between the opposed shells (20 & 40) wherein the central body (60) and the shells (20 & 40) cooperate to limit the motion of the central body (60) with respect to the shells (20 & 40). An assembly (138) for preparing a disc space for the implantation of a prosthesis (10) is further described having a plurality of instruments (152,142) cooperating to guide a tool (140) associated with the assembly (138).

摘要： The invention relates to a technique for precisely locating a line containing a predetermined point within the surgical site using a series of levels and plumb lines and internal anatomical features of the surgical site, using this location to precisely position and temporarily affix a site preparation scaffold relative to the patient's anatomy so that site preparation instruments can be introduced into the site at precise locations governed by the scaffold geometry and patient anatomy. This precise positioning of the scaffold also provides a way for the surgeon to use patient anatomical features to reliably and precisely prepare the surgical site. Scaffolds having angling features further increase the precise preparation of the surgical site. This increased precision in site preparation increases the probability of a successful procedure, and decreases the likelihood that additional surgery may be needed.
