ANAX™ OCT Spinal 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-T3: traumatic spinal fractures and/or traumatic dislocations; instability or deformity; failed previous fusions (e.g., pseudarthrosis); tumors involving the cervical spine; and 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. ANAX™ OCT Spinal System is also intended to restore the integrity of the spinal column even in the absence of fusion for a limited time period 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, ANAX™ OCT Spinal System may be connected to Perfix™ Spinal System and ANAX™ 5.5 Spinal System rods with the rod connectors. Transition rods with differing diameters may also be used to connect ANAX™ OCT Spinal System to Perfix™ Spinal System and ANAX™ 5.5 Spinal System.

The ANAX™ OCT Spinal System is for fixation the cervicocranium (Occiput/C2), the true subaxial region (C3/C6), and the cervicothoracic junction (C7 to T2) by one system. The ANAX™ OCT Spinal System consists of polyaxial screws, polyaxial shank screws, hooks, rods, set screws, transverse (cross) links and occipital plate. Connectors are also provided for surgical convenience. The ANAX™ OCT Spinal System allows surgeons to build a spinal implant construct to stabilize and promote spinal fusion. The single-use ANAX™ OCT Spinal System components are supplied as non-sterile and are fabricated from medical grade titanium alloy (ASTM F136) and medical grade cobalt-chromium-molybdenum alloy (ASTM F1537). All polyaxial screws have self-tapping functions in the ANAX™ OCT Spinal System. Specialized instruments made from surgical instrument grade stainless steel are available for the application and removal of the ANAX™ OCT Spinal System implants.
