Endoscopic Lumbar Fusion Surgery is a minimally invasive surgery indicated as last resort of treatment in conditions that cause spinal instability in lower back such as degenerative disc disease, spondylolisthesis, recurrent disc herniation, degenerative scoliosis, pseudoarthrosis, and spinal stenosis. In this procedure, lumbar spine (lower back) will be approached to remove all or part of herniated disc from in between two adjacent vertebrae followed by fusion of vertebrae on either side of remaining disc space using bone grafts.
The endoscopic procedure employs a surgical device with a tiny camera and lens at one end that will be inserted into the site of surgery through smaller incisions. This enables better view of inner area when connected to a larger screen. Through the other incisions surgical instruments can be inserted for resection and implant. Lumbar fusion surgery can be performed by several approaches:
Anterior lumbar interbody fusion (ALIF)
In ALIF procedure, surgeon approaches the spine from the front of the body to remove disc or bone material from in between two adjacent lumbar vertebrae.
Posterior lumbar body fusion (PLIF)
In PLIF procedure, patient is made to lie on his abdomen and surgery is performed from the back where either an implant is used to fuse the vertebral bones or replace the degenerated disc with an implant.
Transforaminal interbody fusion (TLIF)
In TLIF method, surgeon approaches the damaged lumbar spine from the back, or posterior, of the body to place bone graft between two vertebrae.
Extreme lateral interbody fusion/Direct lateral interbody fusion (XLIF/DLIF)
Extreme lumbar interbody fusion (XLIF) or direct lateral interbody fusion (DLIF) is a surgical procedure in which the patient is made to sleep on his side and the surgery is performed from side of the body. Two incisions will be made, one over the side of waist and the other towards the back muscles.
