XLIF
Also written as: XLIF — extreme lateral interbody fusion
Extreme lateral interbody fusion, a minimally invasive approach accessing the disc space from the patient's side.
Full Definition
XLIF (extreme lateral interbody fusion) is a minimally invasive spinal fusion technique that approaches the disc space through the patient's lateral flank, avoiding the anterior great vessels and posterior neural structures. This approach utilizes the natural anatomical corridor between the psoas muscle fibers to access the lumbar spine. XLIF allows for placement of large interbody grafts while minimizing soft tissue disruption, though it requires careful monitoring to avoid injury to the lumbar plexus within the psoas muscle.
