Long-term Durability of Minimal Invasive Posterior Transforaminal Lumbar Interbody Fusion

The results of this study support the long-term clinical effectiveness of MIS TLIF for varying diagnoses. These results suggest that those undergoing a 1-level or 2-level lumbar fusion improve equally, and that older patients do well with MIS surgery long term. Reoperation rates were acceptable, with excellent surgical durability at 49 months. The benefit of decompression was not assessed in this study, and future studies should assess its impact long term.
