Additional PLIF instruments - FRA instruments are incorporated in PLIVIOS set

The Posterior Lumbar Interbody Fusion (PLIF) instruments allow for a posterior approach, a complete discectomy and implant insertion under distraction. Trial Spacers permit the selection of the most appropriate height so that restoration of disc height can be maintained.

Graft Funnel

The Graft Funnel enables better placement of autograft or allograft in the anterior and medial aspect of the vertebral disc space.

Graft Pusher

The Graft Pusher facilitates in the delivery of autograft or allograft with the use of the Graft Funnel.

PLIF Spreader, 7mm

The PLIF Spreader has the same overall height as the implant and ensures accurate sizing and distraction.

PLIF Trial Spacer

The PLIF Trial Spacer has the same overall height as the implant and ensures accurate sizing and appropriate implant selection.

PLIF Detachable Trial Spacers

The Detachable Trial Spacers have the same geometry and height as the PLIF implants. They ensure accurate sizing and appropriate implant selection. Distraction can be achieved without worrying about compressing the dural sac. Once the Detachable Trial Spacer has been positioned, the dural sac can then slide over the top of the spacer, while implant insertion occurs on the contralateral side.

Intervertebral Disc Shavers

The Intervertebral Disc Shaver allows the surgeon to break-up the nucleus pulposus in a fast and efficient manner, while also beginning to scrape off the cartilaginous layer of the vertebral endplate.

Intervertebral Disc Excisors

Facilitates removal of nucleus pulposus from the intervertebral disc space.

Bone Rasp, Straight, 8 mm width /
Bone Curette, straight, 5.5 mm width, 140 mm length /
Bone Curette, reverse angle, 5.5 mm width, 140 mm length

All three instruments facilitate removal of nucleus pulposus and the cartilaginous layer of the endplates to expose bleeding bone. End-plate preparation can be achieved without damaging the subchondral bone.
