For more than fifty years, anterior cervical discectomy and fusion (ACDF) has been a widely accepted operation for cervical spine degenerative diseases, including disc herniation and spondylosis, that are refractory to medical management. The high rates of success and patients’ satisfaction with ACDF has made the operation a standard of care in common neurosurgical practice, however, the advantages of cervical disc arthroplasty (CDA) over fusion including maintaining normal neck motion and reducing degeneration of adjacent segments of the cervical spine To study the role of cervical disc replacement surgery in cervical pivd patients in both elderly and young population and it’s comparison with anterior cervical dissectomy and fusion with age variability taken into consideration. The inclusion and exclusion criteria used, The operative procedure for both ACDF and CDA, The further follow up studies considering clinical as well as radiological outcome The most commonly indexed levels of CDA were C4–5 and C5–6, accounting for 85%of the entire series. The clinical outcomes, including VAS of neck and arm pain, NDI, and JOA scores were all similarly satisfactory after the surgery, during the follow-up. CDAs has been demonstrated to preserve segmental motion at long-term followup and to decrease the incidence of adjacent-level surgery, as compared to ACDF. Cervical global alignment and the segmental angle at rest improves after cervical arthroplasty
