Cervical disc replacement preserves motion and may reduce adjacent segment degeneration compared to fusion. Early clinical results are promising, but more research is needed to establish its long-term role.

Area of Science:

  • Spine surgery
  • Biomechanical engineering
  • Orthopedic technology

Background:

  • Anterior cervical decompression and fusion (ACDF) is a standard treatment for cervical radiculopathy/myelopathy.
  • Cervical fusion may negatively impact adjacent spinal segment biomechanics.
  • Cervical disc replacement aims to maintain motion and potentially mitigate adjacent segment degeneration.

Purpose of the Study:

  • To critically review the emerging field of cervical disc replacement.
  • To examine arthroplasty designs relevant to the cervical spine.
  • To review design characteristics and clinical data of U.S. Investigational Device Exemption (IDE) cervical prostheses.

Main Methods:

  • Systematic literature review on cervical disc replacement.

Related Experiment Videos

  • Review of arthroplasty technologies for the cervical spine.
  • Analysis of design features and clinical outcomes of U.S. IDE cervical disc replacements.

    • Main Results:

    • Current cervical disc replacement designs include single- or double-articulation implants with various bearing surfaces.
    • In vitro wear testing suggests lower wear rates compared to hip and knee prostheses.
    • Short-term clinical outcomes for cervical disc replacement are encouraging, but prospective randomized trials are absent.

    Conclusions:

    • Cervical disc replacement is an innovative technology that preserves motion and may improve load transfer.
    • Early clinical success reports for cervical total disc replacement are encouraging but preliminary.
    • Further U.S. IDE studies will clarify the role of cervical disc replacement in spine surgery.
