The FLXTM Platform is composed of 8 different interbody fusion implant families: - STALIF C FLXTM - STALIF M FLXTM - STALIF L FLXTM and STALIF Lateral-Oblique FLXTM - ACTILIF C FLXTM - ACTILIF M FLXTM - ACTILIF L FLXTM and ACTILIF Lateral-Oblique FLXTM The FLX™ Platform is a novel range of interbody fusion implants with a complex randomized lattice. The Implants retain all of the benefits of the STALIF® product family while taking advantage of the benefits of porous, laser sintered Ti6Al4V. With the recent advances in additive manufacturing, titanium implants are printed with a porous scaffold structure which reduces the stiffness of the device to potentially reduce subsidence and facilitate bone growth through and around the implant. The FLX™ Platform is intended to be implanted between the vertebral bodies into the cleared disc space to help provide stabilization and height restoration and facilitate the interbody fusion process. The device is intended to be used with bone graft (autograft bone and/or allogenic bone graft composed of cancellous and/or corticocancellous bone graft). The devices are available in a variety of heights, lengths, and widths as well as different lordotic angles to provide surgeons with a wide array of solutions for the highly variable patient population. Surgical instrumentation has been previously developed for the STALIF® Platform and is compatible with the new devices. In addition, interbody-only versions of the FLX™ devices are available in similar size ranges as the STALIF® versions. These devices are not designed to be used with the current STALIF® ABO screw constructs and are instead to be used with supplemental fixation.

The CENTINEL SPINE PCT SYSTEM is intended to provide immobilization of spinal segments as an adjunct to fusion for the following acute and chronic instabilities of 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. The CENTINEL SPINE PCT 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.

The Centinel Spine PCT System consists of a variety of shapes and sizes of rods, hooks, polyaxial screws, and connecting components (e.g., variable and fixed cross connectors). The hooks and polyaxial screws are intended to be attached to the posterior elements of the cervical and/or upper thoracic spine and serve as bone anchors. The rods are longitudinally secured to the bone anchors with the set screw. The various connecting components serve to both secure the construct and provide additional construct configuration options. All implants are manufactured from titanium alloy, Ti6A14V (ASTM F136 or ISO 5832-3)
