title: Anterior cervical discectomy and fusion with ROI-C peek cage: cervical alignment and patient outcomes.
abstract: OBJECTIVE
  The intersomatic cage ROI-C one is a new promising system in anterior cervical discectomy with subsequent fusion.
  
  
  METHODS
  Patients were studied prospectively. ROI-C cages were used in consecutive 32 patients. Intraoperative parameters, clinical features and dysphagia scores were recorded. Radiographs evaluated the height of intervertebral space, the cervical Cobb angle and implant positioning. Data were collected on the last day of hospital stay, at 6 weeks, at 3, 6, 12 and 24 months.
  
  
  RESULTS
  A total of 32 cages were implanted. One patient had transient dysphagia. The intervertebral height and the cervical Cobb angle were significantly improved at 24 months follow-up (P < 0.05). Compared to pre-operatively, visual analog scale pain score and neck pain and disability scale were reduced at 1-month follow-up without change during subsequent follow-up.
  
  
  CONCLUSIONS
  This is the first prospective study on ROI-C cages. Although this is a preliminary assessment, the ROI-C cage may represent an excellent alternative to other devices or simple bone graft.
