Utilization of Total Posterior Spine System facet arthroplasty for management of adjacent segment disease following lumbar spinal fusion: illustrative case

This case highlights ASD as a frequent complication of fusion procedures and illustrates the potential of motion-preserving technologies like the TOPS System to mitigate these effects. Further research is warranted to evaluate long-term outcomes and broader applicability of the TOPS System as a viable alternative to conventional spinal fusion. https://thejns.org/doi/10.3171/CASE25913.
