Outcomes of Posterior Cervical Spine Fusion Using Interfacet Spacers Assessing Fusion Success and Neck Alignment Over Two Years

What this Trial Is About

This research aims to assess fusion rates and cervical spine alignment following posterior cervical arthrodesis surgeries supplemented with cervical interfacet spacers CIS. These procedures are done for conditions like degenerative cervical spondylosis, deformity, tumors, or trauma affecting the cervical spine. The study focuses on how CIS, a device placed under tension in the spine, may improve bone fusion and potentially reduce complications such as nerve root compression and C5 palsy. Participants will undergo posterior cervical fusion surgery involving three or more spinal segments in the neck and upper thoracic region, with CIS used to support the fusion. Data will be collected from medical records, including demographic details, surgical information, clinical status before surgery, and imaging results. Additionally, participants will have a non-standard CT scan two years after surgery to evaluate fusion and spinal alignment. Throughout the study, researchers will collect and review various data for up to two years after surgery, including X-rays, CT scans, and patient-reported outcomes on pain and function. Neurological events will also be monitored. The primary outcomes are the rate of cervical fusion and spinal alignment after two years. Secondary outcomes include pain scores, disability indexes, quality of life measures, and any neurological complications. This detailed follow-up helps understand the long-term effects of CIS in cervical spine surgery.
