Procedure
Lumbar Fusion
Lumbar fusion joins one or more vertebral levels in the lower back to eliminate harmful motion and create a stable foundation for healing and function. Atlas can help explain when Dr. Iyer uses fusion for instability, deformity, recurrent collapse, or selected degenerative problems and how the approach changes depending on the anatomy.
Why fusion is used
Fusion is considered when back pain, nerve compression, or deformity is tied to instability or a motion segment that is no longer behaving normally. Common indications include spondylolisthesis, recurrent collapse, revision surgery, or decompression that would otherwise leave the spine unstable.
How fusion is performed
The operation can be approached from the back, front, side, or with a combined strategy depending on the goals of decompression, alignment, and support. Hardware and graft material hold the segment still so the vertebrae can heal into one stable unit.
What patients should know
Fusion can be highly effective when it treats a clearly defined structural problem, but it is a bigger reconstructive step than a simple decompression. The plan must account for the whole spine, including alignment, bone quality, and the condition of adjacent levels.
Recovery
Recovery takes longer than it does for smaller decompression procedures because the body must heal the fusion while regaining strength and endurance. Follow-up focuses on symptoms, activity progression, and imaging that shows the segment is stabilizing as intended.
