Occipital-Cervical-Thoracic (OCT) Spinal Fixation allows for stabilization and fusion of the cervical spine and the occipito-cervico-thoracic junctions (occiput-T3). The CoreLink Tiger OCT System can also connect to the Tiger Spine System.
COMMON CAUSES AND SYMPTOMS
This approach may be used for cases of congenital deformity, trauma, tumor, or severe rheumatoid arthritis.
Spondylolisthesis is the forward motion (or slip) of one vertebral body over the one below it. This can be caused by a traumatic accident or from degenerative disc disease (DDD). DDD can cause vertebral displacement with vertebral bodies slipping forward, backwards, or loss of disc height.
Degenerative Disc Disease (DDD)
Degenerative disc disease (DDD) is attributed to age and general wear and tear that presents in the disc area with herniated discs or osteophytes (bone spurs). These can cause collapse and pressure on the nerve roots and/or spinal cord. In the cervical spine, this occurs most often at the C5-C6 and C6-C7 levels as discs tend to wear out in places where a flexible region of the spine meets and ridged version.
Trauma in the cervical spine can take many forms and can involve bone, ligaments, or a combination of the two. A compression fracture is a flexion injury, where multiple fragments of bone can be produced, some of which can be displaced into the spinal canal and compress the spinal cord. Extension injuries in the mid-cervical spine can cause disruption of the disc and anterior longitudinal ligament with some displacement of vertebrae.
Revisions of Previous Cervical Spine Surgery
If a prior surgery did not result in fusion, or pseudarthrosis, then a revision may be necessary.
A spinal tumor may require the need for stabilization with an OCT system.
Spinal stenosis is a condition in which the spinal canal starts to narrow. When the spinal canal narrows, the open spaces between the vertebrae may also start to get smaller and this tightness can pinch the spinal cord or the nerves around it. For most, the stenosis results from changes due to arthritis, but may also be due to ossification (bone formation), osteophytes (bony projections), herniated discs, injuries, or tumors. Symptoms may include pain, tingling, and numbness.
Depending on the issue, a posterior cervical fusion may be an option when non-surgical techniques do not relieve symptoms. The primary goals are to provide stability and fusion.
