The CerviFix System is indicated for the following:
DDD (neck pain of discogenic origin with degeneration of the disc as confirmed by patient history and radiographic studies
Spondylolisthesis
Spinal stenosis
Fracture/dislocation
Atlantoaxial fracture with instability
Occipitocervical dislocation
Revision of previous cervical spine surgery
Tumors
The CerviFix Plate/Rods are intended to provide stabilization to promote fusion of the cervical spine and occipitocervical junction (occiput - T3). The screws are limited to occipital fixation only. In addition, the CerviFix Rods are intended to provide stabilization to promote fusion following reduction of fracture/dislocation or trauma in the cervical/upper thoracic (C1-T3) spine.
The CerviFix System can also be linked to the Synthes Universal Spine System using the 3.5/6.0mm parallel connectors from that system.
