When the GS Medical QUASAR Standalone ACIF System is used with all the titanium alloy screws for which the implant is designed it does not require supplemental fixation. When used with fewer screws the implant should be used in conjunction with supplemental fixation that has been cleared for use in the cervical spine. Patients should have at least six (6) weeks of non-operative treatment with an intervertebral cage.

The subject device, the QUASAR Standalone ACIF System cages are designed for restoring the height of the intervertebral space after resection of the disc while also providing biomechanical stability with the addition on an integrated plate. This integrated plate allows for the user to bypass using an additional plate as seen with traditional ACIF spacers. The QUASAR Standalone ACIF System devices consist of implants available in various heights and lordotic configurations with an open architecture to accept packing of bone graft material. The supplementary fixation screws are used along with the subject device cage and plate. The intervertebral body fusion devices are made of hydroxyapatite polyether-ether-ketone (HA PEEK OPTIMA LT1) body with Titanium alloy plates (Ti-6Al-4V) and supplementary screws made up of Titanium alloy (Ti-6Al-4V).

The PYXIS 3D Titanium Cage System is indicated for use with autogenous bone graft in skeletally mature patients with degenerative disc disease ("DDD") at one or two contiguous spinal levels from L2-S 1.
