摘要:
Disclosed herein are systems and methods for identifying the proper implant for use in an arthroplasty procedure and preparing a bone surface for the placement of such implant. In one embodiment, a centering guide system includes a cannulated post (130) and a translucent surface trial (10) where the cannulated post (130) includes a slit (136) defining legs (132) that flex to engage the post when inserted in a hole (11, 12) of the surface trial (10). The system is used to confirm a suitable implant size and place a pilot wire in preparation for implant placement. The cannulated post (130) and the translucent surface trial (10) provide comprehensive visibility of a glenoid surface (2). When inserted into the surface trial (10), an extension of the cannulated post (130) beyond an articulating surface (13) of the surface trial (10) is minimal or nonexistent. In this way, the congruence of the reamed glenoid surface (2) can be evaluated prior to implantation of the implant.
