## Indications for use
Hooks, Plate/Rods, Rods and Screws When intended to promote fusion of the cervical spine and occipitocervical junction (occiput-T3), the plate/rod, rod, hook and screw (3.2 mm cortex) components of the Synthes CerviFix™ System are 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 When used to treat these cervical and occipitocervical conditions, these screws are limited to occipital fixation only. Hooks and Rods The rod and hook components are also intended to provide stabilization to promote fusion following reduction of fracture/dislocation or trauma in the cervical/upper thoracic (C1-T3) spine. Rods, Clamps, Screws and Nuts The rods, clamps, screws and nuts are intended to promote fusion following reduction of fracture/dislocation or trauma in the upper thoracic spine (T1-T3). The use of these screws (3.5 mm, 4.0 mm cancellous and 3.5 mm, 4.2 mm cortex) is limited to placement in T1-T3 in treating thoracic conditions only. They are not intended to be placed in or treat conditions involving the cervical spine. The Synthes CerviFix™ System can also be linked to the Synthes Universal Spinal System using the 3.5 mm/6.0 mm parallel connectors from that system, and via the CerviFix tapered rods using lamina hooks, transverse process hooks, pedicle hooks, 4.2 mm screws, and the 5.0 mm/ 6.0 mm parallel connector.
