Approaches to Lumbar Fusion
There is no single lumbar fusion procedure, and selecting the right approach requires a thorough understanding of the patient's anatomy, the nature and location of the pathology, and the goals of surgery. Our Manhattan team is experienced in all of the following techniques.
Posterior Lumbar Fusion (PLF and PLIF)
The posterior approach accesses the spine from the back and is the most versatile lumbar fusion technique. It allows simultaneous decompression and stabilization and is appropriate for a wide range of conditions, including stenosis with instability, spondylolisthesis, and multilevel degeneration. PLIF adds an interbody cage in the disc space for additional structural support and improved fusion rates.
Transforaminal Lumbar Interbody Fusion (TLIF)
TLIF is a widely used variation of posterior interbody fusion that accesses the disc space from one side through the foramen, reducing the degree of nerve retraction required compared to PLIF. It is a highly effective technique for combining decompression and interbody fusion through a single posterior incision, and is particularly well suited to minimally invasive execution.
Lateral Lumbar Interbody Fusion (LLIF)
The lateral approach reaches the spine through a small incision at the side of the waist, entirely avoiding the back muscles. It provides excellent disc height restoration and indirect nerve decompression and is particularly effective for middle lumbar levels. Posterior fixation with screws and rods is typically added to complete the stabilization construct.
Anterior Lumbar Interbody Fusion (ALIF)
ALIF approaches the spine from the front of the abdomen, providing access to the largest disc space and allowing for maximum interbody support and height restoration. It is most commonly used at L5-S1 and is frequently combined with posterior fixation for optimal overall stability.
