Extreme Lateral Interbody Fusion (XLIF), also known as Lateral Lumbar Interbody Fusion, is a minimally invasive spinal fusion technique used to treat chronic lower back pain caused by disc degeneration, instability, or deformity. By approaching the spine from the side of the body rather than the front or back, XLIF allows access to the damaged disc space while minimizing disruption to muscles and surrounding structures.
At Princeton Neurological Surgery, patients receive advanced spine care from a neurosurgical team led by board-certified neurosurgeon Dr. Edward H. Scheid, Jr. With more than 6,000 successful spine surgeries and extensive experience in complex lumbar conditions, our team carefully evaluates each patient before recommending fusion. Patients in Hamilton and Jersey City, NJ trust our practice for thoughtful diagnosis, precision-based surgical planning, and individualized treatment focused on restoring stability and long-term function.
The XLIF Procedure
XLIF is performed on the lumbar spine through a small incision in the patient’s side. During the procedure:
- The damaged intervertebrael disc is removed
- The disc space is restored to proper height
- A spacer filled with bone graft material is inserted
- Stabilization is achieved to promote fusion between the vertebraee
Unlike posterior fusion procedures that require significant muscle retraction, the lateral approach allows surgeons to access the spine by gently separating muscle fibers rather than cutting through them. It also avoids many of the major vascular structures encountered in anterior approaches.
Because the disc space is accessed directly from the side, vertebrael bone removal is minimized. This approach often results in reduced tissue disruption and may contribute to faster recovery compared to traditional fusion techniques. However, XLIF is typically limited to vertebrael levels that can be safely accessed laterally and is generally performed on one or two levels.
Conditions Treated With XLIF
XLIF may be recommended for patients experiencing:
- Degenerative disc disease
- Lumbar spinal instability
- Spondylolisthesis
- Degenerative scoliosis
- Disc space collapse causing nerve compression
Candidacy depends on both the location of the affected segment and whether the anatomy allows safe lateral access. A comprehensive evaluation, including MRI and CT imaging, helps determine whether XLIF is the most appropriate fusion option.
How is This Surgery Performed?
The procedure is performed under general anesthesia with the patient positioned on their side. Specialized instruments and real-time imaging are used to identify and avoid nerve structures during access to the disc space.
After disc removal, a spacer containing bone graft material is inserted. In some cases, bone morphogenetic protein (BMP) may be used to stimulate bone growth and promote successful fusion. Additional instrumentation such as rods or screws may be placed to enhance stability while fusion develops.
Surgical time varies depending on the number of levels treated and the complexity of the spinal condition.
XLIF Recovery
Most patients remain in the hospital overnight following surgery. Early movement is encouraged to promote circulation and healing. A structured rehabilitation plan may be recommended to restore strength and flexibility.
Activity restrictions typically include:
- Avoiding heavy lifting
- Limiting twisting motions
- Reducing bending at the waist
Many patients return to non-strenuous work within several weeks, while more rigorous activities are gradually resumed based on healing progress and the extent of fusion.
Potential XLIF Risks And Considerations
Although XLIF is considered safe and minimally invasive, it remains a form of spinal surgery and carries potential risks, including:
- Infection
- Nerve irritation or weakness
- Hardware failure
- Incomplete fusion
- Persistent pain
Careful surgical planning and precise technique help minimize these risks and improve outcomes.
