TO Compare The Clinical And Radiographic Outcomes of DCI VS ACDF For The Treatment Of
      Single-Level Cervical Degenerative Disc Disease (DDD)

Dynamic Cervical Implant (DCI) Versus Anterior Cervical Discectomy And Fusion(ACDF) For The Treatment Of Single-Level Cervical Degenerative Disc Disease (DDD): An RCT

Cervical Degenerative Disc Disease

Anterior cervical discectomy and fusion (ACDF) is an effective and safe treatment for
      patients with radiculopathy and myelopathy. However, in the untreated levels adjacent to a
      fusion, increased motion and elevated intradiscal pressures have been reported. Some
      investigators have postulated that these changes may lead to an increased risk of adjacent
      segment degeneration (ASD). Limitations and problems with ACDF have led some investigators to
      explore the motion-preserving surgeries, such as cervical total disk replacement (TDR).
      Although TDR has been shown to reduce adjacent-level intra discal pressures and provide a
      more physiological overall cervical but also index- and adjacent-level range of motion (ROM)
      while maintaining sagittal alignment. Recent studies have also highlighted the potential
      limitations of TDR. Dynamic cervical implant (DCI) is a type of anterior decompression and
      cervical non-fusion implant that was initially conceived as a method to combine the potential
      advantages of fusion and TDR. The DCI is intended to provide controlled, limited flexion and
      extension-the primary motions in the sub axial cervical spine-that is greater than that seen
      with fusion, but less than that achieved with TDR .
