Read the full statement (186 words)

When intended to promote fusion of the cervical spine and occipito-cervico-thoracic junction (Occiput-T3), the Ascent POCT System is indicated for:

a. degenerative disc disease (defined as neck pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies);

b. spondylolisthesis;

c. fracture/dislocation;

d. spinal stenosis;

e. atlanto-axial fracture with instability;

f. occipito-cervical dislocation;

g. tumors;

h. revision of previous cervical spine surgery

The occipital bone screws are limited to occipital fixation only. The use of the multi-axial screws is limited to placement in the upper thoracic spine (T1-T3) for the treatment of thoracic conditions only. They are not intended to be placed in the cervical spine. The lateral offset adapter is indicated for use in the upper thoracic spine (T1-T3). The hooks are intended to be placed from C1 to T3. The Songer Cable (titanium) System to be used with the Ascent Posterior Occipital Cervical Thoracic System allows for wire/cable attachment to the posterior cervical spine.

The Ascent Posterior Occipital Cervical Thoracic System can also be linked to the Orthofix Spinal Fixation System using the Ascent Axial or Parallel Rod Connector.

Indications for use as stated in the FDA summary.
