Minimally Invasive Lumbar Fusion (MIS-TLIF)
Fast facts on minimally invasive lumbar fusion (MIS-TLIF):
- Surgery is done through 2 small paraspinal incisions, instead of a midline incision to protect the midline muscle insertions.
- Tubular retractors are utilised to perform decompression and introduce cages followed by screw placement.
- Allows quicker recovery and rehabilitation.
- Studies also suggest the reduced rate of infection and better wound healing.
What is Minimally Invasive Lumbar Fusion (MIS-TLIF):
Transforaminal Lumbar Interbody Fusion (TLIF) is a Surgery that uses an approach from the back of the spine to fuse the lumbar spine. TLIF is a short form for:
Transforaminal: By removing the facet joint on the problematic side, the spine and intervertebral disc can be accessible on one side only. The lumbar spine is reached through one or two small incisions in the lowest part of your lumbar region, using a surgical approach from behind.
Lumbar: The lumbar spine contains one or more fused vertebrae (bones).
Interbody: Following the removal of the intervertebral disc, fusion occurs between the two vertebral bodies. The fusion takes place all the way throughout the disc space.
Fusion: To stabilise the spine, a bone bridge is formed between parts of the spine.
