Abstract

Systems and methods for implantation of an intervertebral disc prosthesis include the prosthesis, a cartridge, and an instrument. Prior to implantation of the prosthesis, the cartridge receives and engages with the prosthesis to form an assembly. In addition, the instrument receives the assembly within an opening in an outer housing and engages the cartridge with a coupler of a locking shaft. Following implantation of the cartridge, actuation of a release driver causes an expansion bit of the release driver to engage release tabs on the cartridge to cause the cartridge to disengage from the prosthesis. The systems and methods optionally include a trial implant and/or an osteotome for trialing prior to implantation of the prosthesis.
