Also known as an XLIF (Extreme Lateral Interbody Fusion), is an approach to the spine through lateral flank. It is
most commonly used to operate upon the L2-3, L3-4 and sometimes L45 levels. Most surgeons have seen success in using this procedure for adjacent segment disease after a previous fusion. For instance, a patient undergoes a fusion at L4-5 and later develops stenosis at L3-4. Rather than extend the fusion, an XLIF can be performed in a short period of time, minimal surgical exposure, and with the patient going home the next day.
The surgery takes approximately 60 minutes. Patients usually go home the same day.
