Posterior cervical fixation systems

Infinity™ 2 OCT system

<p>The Infinity™ 2 occipitocervical upper thoracic (OCT) system stabilizes the spine of the craniocervical, cervical, and/or upper thoracic spine (occiput-T3).</p>

Indications, Safety, and WarningsIndicationsThe Infinity™ OCT system is intended to provide immobilization and stabilization of spinal segments as an adjunct to fusion for the following acute and chronic instabilities of the craniocervical junction, the cervical spine (C1 to C7), and the thoracic spine from T1 to T3:

Traumatic spinal fractures and/or traumatic dislocations

Instability or deformity

Failed previous fusions (e.g., pseudarthrosis)

Tumors involving the cervical spine

Degenerative disease, including intractable radiculopathy and/or myelopathy, neck and/or arm pain of discogenic origin as confirmed by radiographic studies, and degenerative disease of the facets with instability

The Infinity™ OCT system is also intended to restore the integrity of the spinal column even in the absence of fusion for a limited time in patients with advanced stage tumors involving the cervical spine in whom life expectancy is of insufficient duration to permit achievement of fusion. In order to achieve additional levels of fixation, the Infinity™ OCT system may be connected to the CD Horizon™ spinal system and Vertex™ reconstruction system rods with the Infinity™ OCT system rod connectors. Transition rods with differing diameters may also be used to connect the Infinity™ OCT system to the CD Horizon™ spinal system.Refer to the CD Horizon™ spinal system package insert and Vertex™ reconstruction system package insert for a list of the indications of use. Note: The 3.0 mm multi-axial screw (MAS) requires the use of MAS Crosslink™ at each level in which the 3.0 mm screw is intended to be used.
The lateral offset connectors and MAS extension connectors are intended to be used with 3.5 mm and larger diameter multi-axial screws. The lateral offset connectors and MAS extension connectors are not intended to be used with 3.0 mm screws.RisksAlong with the benefits of this technology, there are also potential risks. Risks associated with the Infinity™ OCT system include, but are not limited to:

Disassembly, bending, and/or breakage of any or all of the components

Pressure on the skin from the component parts which could cause skin penetration, irritation, and/or pain, tissue or nerve damage, and/or scar formation

Features

Improved visibility and line-of-sight with reduced length and lower profile instrument designs^†
Multiple screwdriver options with improved driver/screw engagement^†
Enhanced final tightening experience
Expanded set of tools designed to address the challenging anatomy of the occipitocervical junction^†

Multi-axial screw

Up to 60⁰ of angulation in any direction

Reduction meets angulation: reduction multi-axial screw

Additional 10 mm of reduction in the screw head allow for easier rod capture. The screw offers up to 60° angulation and reduction can be achieved at every angle.

Full spectrum of rod diameters and materials

Accommodating various spinal applications and construction demands

Versatility at the CT junction

Simplifying the complex, including the cervical thoracic (CT) junction

Versatility at Junctions screws and rods

Optimized connecting components

Versatility with simplified assembly

Refined navigated instruments

Designed for the posterior cervical upper thoracic working space

The Infinity™ OCT system offers an optimized adjustable drill guide.

Powerease™ system compatible

Navigated drills, taps, and drivers integrated with Powerease™ system

The Infinity™ OCT system provides longer drilling depths with Powerease™ drill.

Screw options that offer strong cervical fixation, lower anatomic risk^‡,1

PILAR™ technique trajectory range is 25 to 45 degrees.

Meet the PILAR™ technique, a procedure with pedicle inlet screw options that offer less anatomic risk compared to a pedicle trajectory using a full pedicle screw.^‡,1 The PILAR™ technique can achieve improved fixation and streamlined workflow benefits of a traditional pedicle screw without the traditional pitfalls of neurological and vascular risk.^‡,1
