Procedure
Lateral Lumbar Fusion (XLIF/LLIF)
Lateral lumbar fusion, often called XLIF or LLIF, approaches the lumbar spine from the side so the disc can be reconstructed through a less disruptive corridor in selected patients. Atlas can explain why Dr. Iyer may use this technique for disc collapse, deformity, or indirect decompression and why level selection and surrounding anatomy are critical to its safe use.
Why lateral fusion is used
This approach is often chosen when the goals include restoring disc height, opening foraminal space indirectly, and improving coronal or sagittal alignment. It can be especially helpful in selected degenerative and deformity cases where a large interbody implant is beneficial.
How the procedure works
The surgeon reaches the disc space from the patient's side, removes the disc, and places a spacer that supports correction and fusion. Depending on the case, posterior screws or other supplemental fixation may also be added to complete the construct.
What makes it different
The lateral corridor can reduce the need for a wide posterior exposure, but it is not suitable for every level or every anatomy. Preoperative planning must account for psoas muscle anatomy, nearby nerves, and whether direct decompression is also required.
Recovery and goals
The goals are improved alignment, restored disc height, and durable stabilization with less soft-tissue disruption in the right patient. Recovery follows the usual fusion principles, with gradual return to activity as alignment and healing are confirmed.
