Minimally Invasive Lumbar Spinal Fusion Is More Effective Than Open Fusion: A Meta-Analysis.

Although present findings are limited by insufficient evidence and there is a lack of adequately powered high-quality randomized controlled trials to address this gap in evidence, our results support that minimally invasive lumbar fusion is more effective than open fusion for adult spondylolisthesis and other spondylosis in terms of functional improvement, reducing infection rate, and decreasing blood loss and hospital stay.
