MIS XLIF®: Extreme Lateral Interbody Fusion
Overview
Extreme Lateral Interbody Fusion (XLIF®) is typically used to treat leg or back pain caused by degenerative disc disease.
An XLIF® procedure typically involves one small incision on the patient’s side. The surgeon inserts a probe and guides surgical instruments in the incision. The probe is used to help avoid interrupting the nerves. X-ray images guide the probe to the proper place in the spine. Using dilation tubes and a retraction device the surgeon gains access to the spine and removes the damaged disc. Once the disc is removed an implant filled with bone graft is placed in the empty disc space. This realigns the spine and relieves pressure from pinched nerve roots.
Using the XLIF® procedure, instead of traditional spine surgery, the surgeon avoids cutting into major muscles by making the incision in the patient’s side — which can mean less post-operative pain. This procedure is generally performed in an outpatient setting or 23 hour stay.
Comparison of Minimally Invasive Spine Surgery Approaches
| Approach | Full Name | Access Route | Typical Levels Treated | Muscle Disruption | Advantages | Risks/Limitations |
|---|---|---|---|---|---|---|
| TLIF | Transforaminal Lumbar Interbody Fusion | Posterior (from the back, side of spinal canal) | L2 to S1 | Moderate | Good disc space access; unilateral approach reduces nerve retraction | Nerve root injury risk; limited disc space visualization |
| XLIF | Lateral Lumbar Interbody Fusion (eXtreme) | Lateral (through psoas muscle) | T12 to L5 (not L5-S1) | Minimal | Large graft placement; minimal blood loss | Risk to lumbar plexus; not suitable for L5-S1 |
| iLIF | Interlaminar Lumbar Interbody Fusion | Posterior (between spinous processes) | L2 to S1 | Minimal | Preserves stabilizing structures; reduced blood loss | Technically demanding; newer technique, limited long-term data |
| PLIF | Posterior Lumbar Interbody Fusion | Posterior (midline) | L2 to S1 | High | Direct access to disc; bilateral cage placement possible | More muscle disruption; higher blood loss |
| ALIF | Anterior Lumbar Interbody Fusion | Anterior (through abdomen) | L4 to S1 | Minimal (no back muscle disruption) | Wide disc access; large implant size possible | Major vessel injury risk; requires vascular access surgeon |
