The Prodisc total lumbar disc replacement offers effective, long-term relief for degenerative disc disease. While generally safe, younger patients and those with prior surgery experienced slightly worse outcomes.

Area of Science:

  • Spine Surgery
  • Biomechanical Engineering
  • Orthopedic Research

Background:

  • Symptomatic lumbar degenerative disc disease presents treatment challenges.
  • Arthrodesis can lead to pseudarthrosis, donor site pain, and adjacent segment degeneration.
  • Total disc replacement offers potential for long-lasting relief.

Purpose of the Study:

  • To present clinical and radiographic outcomes of Prodisc total lumbar disc replacement.
  • To evaluate results seven to eleven years post-implantation.

Main Methods:

  • Sixty-four patients received Prodisc lumbar total disc replacement (1990-1993).
  • Mean follow-up was 8.7 years.
  • Clinical outcomes (pain, disability) and radiographic findings were assessed; subgroup analyses were performed.

Main Results:

  • Significant improvements in pain, radiculopathy, disability, and functional scores were observed.
  • Excellent or good results were achieved in 41/55 patients.
  • No radiographic evidence of device failure; 5 approach-related complications occurred.

Conclusions:

  • Prodisc lumbar total disc replacement is effective and safe for degenerative disc disease.
  • Prior surgery or younger age (<45) were associated with slightly poorer outcomes.
  • Longer follow-up and comparative trials with arthrodesis are warranted.
