Intervertebral disc prostheses show promising results for treating disc-related pain. Ongoing research and new designs for lumbar and cervical disc replacements are advancing this surgical option.

Area of Science:

  • Spine surgery and biomechanical engineering.
  • Orthopedic implant technology.

Background:

  • The quest for functional intervertebral disc prostheses began in the 1950s.
  • Disc replacement therapy emerged as viable in the late 1980s, with European devices now in US clinical trials.
  • Cervical disc replacements are in early development and evaluation stages.

Purpose of the Study:

  • To provide an overview of outcomes and complications associated with various lumbar and cervical disc replacement devices.
  • To synthesize current literature on intervertebral disc prostheses.

Main Methods:

  • A comprehensive literature review was performed.
  • Conference proceedings were also reviewed.
  • Articles were categorized by topic: lumbar total disc replacement, disc nucleus replacement, and cervical disc replacement.

Main Results:

  • Total disc replacement yields favorable outcomes in 63-85% of patients.
  • Early experiences highlighted the importance of patient selection, surgical technique, and device sizing.
  • Disc nucleus replacement has shown good results but faces challenges with device displacement.
  • Cervical disc replacement reports are increasing, with new designs under evaluation.

Conclusions:

  • Functional disc replacement is poised to become a significant tool for treating intractable disc-related pain.
  • Advancements in materials and implant designs offer a promising future for disc prostheses.
  • Long-term studies are crucial to determine the safety and efficacy of these emerging technologies.
