A laminar fixation system includes an implant and a implant installation tool for use with laminar fixation tape for retaining a spine rod relative to a vertebra of the spine. The implant has a spine rod locking portion, a laminar fixation tape channel, and a laminar fixation tape locking portion. The implant installation tool has a laminar fixation tape locking actuator for manipulating the laminar tape locking portion of the implant, and a laminar fixation tape tensioning sub-assembly for tensioning laminar fixation tape received in the implant. The laminar fixation tape locking actuator and the laminar fixation tape tensioning sub-assembly of the installation tool each operates independent of each other. Attachment of the implant to a spine rod via the spine rod locking portion of the implant is independent of laminar fixation tape tensioning and laminar tape fixation to the implant.
