摘要：
Trials for spinal surgery include: (a) a trial implant portion having a shape corresponding to an implantable spinal disc implant； (b) a shaft connected to the trial implant portion； and (c) at least one axially extending cutting guide slot attached to the shaft at a position that is axially spaced apart from the trial implant portion, the cutting guide slot configured to releasably slidably receive and guide a cutting blade toward vertebral bone. Also described are additional surgical instruments, including, for example, pilot-hole punches, inserters, and methods of cutting keelways.
