Summary
Lumbar facet arthroplasty (LFA) shows promise for spondylolisthesis surgery, offering clinical improvement and stability. Economic analyses suggest the TOPS system is a cost-effective alternative to traditional methods.
Area of Science:
- Orthopedic Surgery
- Spinal Surgery
- Biomaterials
Background:
- Surgical correction for spondylolisthesis includes spinal fusion and dynamic stabilization like lumbar facet arthroplasty (LFA).
- LFA is an emerging technique requiring further research on its efficacy and safety.
Purpose of the Study:
- To systematically review the scientific evidence on lumbar facet arthroplasty (LFA) for surgical correction of spondylolisthesis.
Main Methods:
- A PubMed search was conducted for studies published in the last 10 years using specific keywords related to LFA and spondylolisthesis.
- Eight studies were included after initial screening and exclusion of irrelevant papers.
Main Results:
- Lumbar facet arthroplasty (LFA) consistently demonstrated significant clinical improvement and maintained radiological stability.
- The TOPS system, a type of LFA, showed low complication rates and was found to be cost-effective compared to traditional spinal fusion (TLIF).
Conclusions:
- Lumbar facet arthroplasty (LFA), particularly the TOPS system, appears to be a viable and advantageous surgical option for degenerative spondylolisthesis.
- This technique offers both clinical benefits and long-term economic advantages over conventional surgical approaches.
