Read the full statement (149 words)
The GS Medical QUASAR Stand-alone ACIF System is indicated for use in skeletally mature patients with degenerative disc disease (DDD) of the cervical spine with accompanying radicular symptoms at one disc level. DDD is defined as discogenic pain with degeneration of the disc confirmed by patient history and radiographic studies. The GS Medical QUASAR Stand-alone ACIF System is used to facilitate intervertebral body fusion in the cervical spine at the C3 to C7 disc levels using autograft bone. 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 prior to treatment with an intervertebral cage.
