Microendoscopic Lumbar Interbody Fusion (MELIF)

Lumbar interbody fusion remains a cornerstone in the surgical management of degenerative lumbar disorders, including spondylolisthesis, segmental instability, and discogenic low back pain. Traditional posterior lumbar interbody fusion (PLIF) [1], while effective, involves laminectomy, neural decompression, interbody cage placement, and pedicle screw instrumentation, often requiring extensive muscle dissection and neural manipulation.
