This video: Conditions Repaired by Lumbar Fusion Using TLIF, explains the Transforaminal Lumbar Interbody Fusion (TLIF) technique. Used properly, the TLIF is a surgical procedure that can cure many maladies of the lumbar spine. The technique can stabilize the unstable segment, open the central canal in a condition called spinal stenosis, enlarge a nerve hole in the case of foraminal stenosis or foraminal collapse and stop the motion of a painful degenerative disc. In the case of multiple recurrent disc herniations, this is a very valuable procedure because it removes the offending disc almost completely. For isthmic spondylolysthesis, this is one of the best procedures to stabilize this condition. This procedure in scoliosis surgeries will allow a higher fusion rate and better stabilization.
