M 0086  en  SUMMIT® SI Occipito-Cervico-Thoracic (OCT) Spinal Fixation System and MOUNTAINEER® OCT Spinal System IMPORTANT NOTE TO OPERATING SURGEON The SUMMIT® SI Occipito-Cervico-Thoracic (OCT) System and MOUNTAINEER® OCT Spinal System implants, like other internal fixation devices, have a finite useful life. The patient’s activity level has a significant impact on this useful life. Your patient must be informed that any activity increases the risk of loosening, bending, or breaking the implant components. It is essential to instruct patients about restrictions on their activities in the postoperative period and to examine the patient postoperatively to evaluate the development of the fusion mass and the status of the implant components. Even if solid bone fusion occurs, implant components may nevertheless bend, break, or loosen. Therefore, the patient must be made aware that implant components may bend, break, or loosen even though restrictions in activity are followed. Because of the limitations imposed by anatomic considerations and modern surgical materials, metallic implants cannot be made to last indefinitely. Their purpose is to provide temporary internal support while the fusion mass is consolidating. These types of implants are more likely to fail if no bone graft is used or if a pseudo­arthrosis develops. The surgeon may determine to remove these implants after bone fusion occurs. The possibility of a second surgical procedure must be discussed with the patient, and the risks associated with a second surgical procedure must also be discussed. If the implants do break, the decision to remove them must be made by the physician who must consider the condition of the patient and the risks associated with the presence of the broken implant.  DESCRIPTION The SUMMIT SI OCT Spinal System and MOUNTAINEER OCT Spinal System are designed to stabilize and promote fusion. The SUMMIT SI OCT Spinal System and MOUNTAINEER OCT Spinal System consist of plates, nuts, bone screws, rods, transverse rod  2017-06-20 11:03:32  connectors, lateral offset connectors, head-to-head connectors, cable connectors, dual wedding band and axial connectors, set screws, minipolyaxial screws, monoaxial screws, hooks and SONGER® Cables. The components are manufactured from Titanium Alloy (Ti-6Al-4V). MOUNTAINEER Longitudinal rods are also available in cobaltchromium-molybdenum alloy conforming to ASTM F-1537. Cobalt-chromium-molybdenum alloy rods are intended for use with titanium components only. For occipitocervicothoracic fusion, either the transition rod is bent and cut to the appropriate length or a pre-bent rod is used. The occipital plate is fixed to the occiput with bone screws and the transition rod is attached to the plate by a locking mechanism. This locking mechanism consists of a bolt and a washer which are free to rotate and translate along a slot in the occipital plates. The rod loads from the top and is fixed and locked into place. Sub-axially, cable connectors are fixed to the transition rod and attached to the spine via sublaminar cabling looped through the cable connectors. Hooks are also available for fixation to the spine. The end of the construct is stabilized with polyaxial screws to the upper thoracic spine, as required. The SUMMIT SI OCT System and MOUNTAINEER OCT Spinal System can also be linked to the ISOLA®, MONARCH®, MOSS® MIAMI, VIPER® and EXPEDIUM® systems using the dual wedding band (side-by-side) and axial connectors (end-to-end), and via dual diameter rods. The occipital plate assemblies are offered in a variety of sizes and configurations. These plates are designed to allow for contouring intraoperatively by the surgeon as required. The unicortical occipital bone screws are 4.5mm or 5.25mm in diameter and are available in multiple lengths.
