Read the full statement (123 words)

The Keos Anterior Cervical Interbody Fusion Devices (IBFDs) are 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. Keos Anterior Cervical IBFD's are used to facilitate intervertebral body fusion in the cervical spine and are placed via an anterior approach at one disc level (C2-T1) using autogenous bone graft. Keos Anterior Cervical IBFD's are intended to be used with supplemental fixation systems that have 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.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
