Applying ROI Interbody Fusion Cage for Anterior Cervical Intervertebral Disc Resection Arthrodesis Treat Early Cervical Degenerative Disease / 浙江中医药大学学报

ABSTRACT

[Objective] The objective of the study was to determine the clinical and radiological outcomes of cervical interbody fusion using ROI cages. [Methods] Patients showing degenerative cervical mono- or bi-level pathology were prospectively included. Using AP and lateral radiographs, segmental height of the treated segments was determined quantitatively. Cage characteristics were described qualitatively. Clinical data such as the neck disability in-dex(NDI), numeric rating scale(NRS) were col ected at al time points .[Results] The scores of NDI, NRS were decreased gradual y, and stable after half year;but they were respectively reduced to 8.64 and 1.57 from 23.32 and 8.93, with difference of statistical meaning. The intervertebral angle increased af-ter operation, then decreased gradual y and was stable after half year, was 3.6 °after 1 year. The intervertebral height was maximum after operation, then re-duced gradual y, and was 5.32mm or so after 1 year. 16 patients were al cured after 1 year, with short fusion rate reaching 100%. [Conclusions] The clini-cal and radiological short-term outcome of anterior cervical discectomy and fusion using ROI cage are excel ent.
