Area of Science:

  • Orthopedics
  • Spinal Surgery
  • Biomechanical Engineering

Background:

  • Degenerative lumbar spine disease is common with aging, causing pain and neurological issues.
  • Traditional treatment involves decompression and potential lumbar fusion when conservative methods fail.
  • Lumbar fusion can lead to adjacent segment degeneration and reduced mobility.

Purpose of the Study:

  • To review the mechanism, early clinical outcomes, and patient selection for the Total Posterior Spine (TOPS) System.
  • To evaluate the TOPS System as a dynamic alternative to lumbar fusion.
  • To identify potential benefits and complications associated with the TOPS System.

Main Methods:

  • Comprehensive narrative literature review.
  • Analysis of studies on the TOPS System's mechanism and early clinical outcomes.
  • Examination of patient selection criteria and reported adverse effects.

Main Results:

  • The TOPS System provides multiaxial stabilization, maintaining spinal mobility and flexibility.
  • Early clinical outcomes show positive results, suggesting potential efficacy.
  • Adverse effects have been reported, necessitating careful patient selection and monitoring.

Conclusions:

  • The TOPS System presents a promising dynamic arthroplasty option for degenerative lumbar spine conditions.
  • Further prospective trials are essential to fully understand the long-term complications and benefits.
  • Optimizing patient selection will be crucial for successful implementation of the TOPS System.
