Overview
Anterior Lumbar Interbody Fusion (ALIF) is a surgical procedure that involves removing a damaged disc from the lumbar spine and fusing the adjacent vertebrae from the front (anterior) side. It is used to treat various spinal conditions, including degenerative disc disease and spondylolisthesis.
Causes
ALIF is typically recommended for patients with chronic lower back pain, spinal instability, or deformities that have not responded to conservative treatments. The anterior approach avoids the spinal muscles and allows for the placement of larger bone grafts.
Treatment
The surgeon accesses the spine through an incision in the abdomen, removes the damaged disc, and inserts a bone graft or interbody cage. Screws and rods may also be used to ensure stability while the bones fuse together.
Benefits
ALIF offers several advantages, including better access to the disc space, the ability to place larger implants, and less disruption to the spinal muscles. It also provides excellent alignment and fusion rates.
Medical Terms
- Anterior: Referring to the front side of the body.
- Interbody Cage: A device placed between the vertebrae to maintain disc height and support fusion.
- Disc Space: The space between two vertebrae where the intervertebral disc resides.
