Spinal prosthetic devices having selectable and/or changeable centers of rotation are disclosed. In one aspect, a spinal prosthesis kit includes a first component, a second component, and a plurality of inserts. The first component has a first articulating surface that includes a first articulating structure. The second component has a second articulating surface with a recessed opening adapted to receive one of the plurality of inserts. Each of the plurality of inserts includes a second articulating structure adapted to moveably mate with the first articulating structure. The second articulating structure is positioned in a different location on each of the plurality of inserts. In some embodiments, the articulating structures are moveably mating projections and recesses. In another aspect, a revisable prosthetic device having a first component, a second component, and an insert is provided.
摘要:
Devices and methods to insert a prosthetic implant into an intervertebral disc space. The device may comprise pivotally connected channel members and a locking mechanism pivotally connected to the channel members. The locking mechanism may comprise a latch that engages a slot in the sidewalls of a channel member to at least partially cover an open side of the channel members and lock the channel members in place. A prosthetic implant may be loaded into the channel members in a relaxed configuration and then unfolded to an implantation configuration by pivoting the channel members.
