Clinical and Radiological Outcomes of Posterior Cervical Fusion Supplemented With Interfacet Spacers
Ohio State University
Summary
This is a prospective study to assess fusion rates and cervical sagittal parameters following posterior cervical arthrodesis procedures supplemented with CIS. Data will be collected from medical records for up to 730 days after surgery. Data to be collected will be demographic, preoperative clinical information, surgical details, and radiographic information. Patients will also undergo a non-standard of care CT scan 2 years after surgery.
Description
Background and Rationale Posterior cervical fusion surgeries are performed for degenerative cervical conditions, cervical deformity, cervical tumors, and cervical trauma. They are preferred over an anterior approach when the pathology is located posterior to the spinal cord or when multiple levels must be addressed. Degenerative cervical spondylosis contributes to loss of disc height, facet arthropathy and hypertrophy, and retrolisthesis of the vertebral bodies, all of which can lead to foraminal stenosis, or narrowing around the exiting nerve roots. This is often accompanied by loss of cervi…

Interventions
- DeviceCervical Interfacet Spacers
The use of Cervical Interfacet Spacers is a relatively novel technique shown to be useful for posterior fusion to address symptomatic pseudoarthrosis (fusion failure) after anterior cervical arthrodesis \[2\]. CIS have a relatively large osteoconductive surface area and are placed under tension in the interfacet space, which together favorably influence bony fusion \[2\].
