Zero-P. Zero profile anterior cervical interbody fusion (ACIF) device.

The aiming device and the implant holder do not have adepth limiter, therefore an image intensifier should be usedto check the position while inserting.Using the aiming deviceAttach the aiming device to the implant by aligning thescrew holes of the implant with the retention features on theaiming device and then expanding the aiming device. Oncethe implant is securely attached, carefully insert the implantinto the distracted segment.If necessary, the top of the aiming device can be tapped withthe mallet to advance the implant into the disc space.If distraction has been applied, release the distraction whileleaving the aiming device attached to the implant.Using the implant holderThe implant can be inserted into the disc space with the forceps-typeimplant holder. Once the implant is partially introducedinto the disc space the implant can be advanced tothe correct posterior depth using the flat and/or the impactorwith ball tip.Important: Verify final implant position relative to the vertebralbodies in the AP and lateral direction with the help of anintraoperative x-ray. The PEEK spacer has a single posterior x-ray marker incorporated into the implant to enable accurateintraoperative radiographic assessment of the implant position.Note: The recommended orientation for the implant is withthe medial screws pointing caudally. For convex shaped spacersthis is the only orientation possible.Synthes 11
