Posterior Cervical Fusion refers to stabilization of the cervical spine (neck) thru various instrumentation techniques. Such procedures may be necessary following neck fractures, correction of cervical instability, cervical deformities, along with tumor resections, or to aid prior failed anterior fusions.

During this procedure titanium screws, rods, and sometimes wires are used to hold multiple levels of the spine together to act as an internal brace. This allows the stabilized bones to grow together and produces a solid bony fusion. Such fusion procedures maintain the proper alignment of the spine especially in the cases of trauma or instability and help to prevent further injury of the spinal cord.
