Surgical Outcomes of Cervios ChronOS Cage Implantation for Degenerative Cervical Intervertebral Disk Disorder

This study describes the outcomes of CCOS for anterior cervical discectomy with interbody fusion (ACD-IBF) in patients at the Chang Gung Memorial Hospital. Materials and Methods: Retrospectively reviewed 32 patients underwent ACD-IBF with 51 CCOS cages from 2007 to 2008. All patients had either intractable preoperative cervical radiculopathy or myelopathy for 3 months duration and underwent follow-up for >2 years. Postoperative outcomes were classified as favorable or unfavorable. Rigid bone fusion was defined as an interspinous distance ≤2 mm on dynamic lateral cervical radiographs and absence of radiolucent gaps between vertebral endplates and CCOS. Anterior disk height and interbody height were used for subsidence evaluation. Results: The postoperative outcomes were favorable in 86.7% and unfavorable in 13.3% of the patients. Two years after surgery, 90.01% had rigid bone fusion. The anterior disk height was increased at postoperative day 1 and month 3 (P0.05). The interbody height did not change significantly throughout the follow-up. The segmental angle had significant lordosis at postoperative day 1 and month 3 (P
