This study evaluated a new cervical disc prosthesis. The device failed to maintain mobility in most patients, leading to pain and fusion, indicating it did not achieve its intended purpose.

Area of Science:

  • Spine surgery
  • Orthopedic implants
  • Cervical spine disorders

Background:

  • Adjacent segment degeneration is a concern following cervical arthrodesis.
  • Cervical prostheses are designed as an alternative to fusion.
  • Previous prostheses have been bulky and their efficacy unproven.

Purpose of the Study:

  • To assess the feasibility of a low-profile cervical disc prosthesis.
  • To evaluate the prosthesis's efficacy in maintaining intervertebral mobility.
  • To determine the complication rate associated with the prosthesis.

Main Methods:

  • Prospective preliminary trial involving 10 patients (5 men, 5 women) aged 36.
  • Patients underwent single-level cervical discectomy for herniated discs causing cervicobrachial pain.

  • A low-profile disc prosthesis was implanted post-discectomy.

    • Main Results:

    • Cervicobrachial pain resolved in all 10 patients initially.
    • One patient developed intense neck pain requiring revision to arthrodesis.
    • Eight patients experienced loss of mobility at the treated level, with subsequent fusion.

    Conclusions:

    • The cervical disc prosthesis failed to consistently maintain intervertebral mobility.
    • Persistence of mobility in two patients led to pain and need for revision.
    • The prosthesis did not achieve the desired therapeutic effect.
