Procedure
Laminectomy
Laminectomy removes part of the back of the vertebra to create more room for the nerves, most often in patients with lumbar spinal stenosis. Atlas can help explain why Dr. Iyer may recommend decompression when walking is limited by nerve crowding and how he decides whether the spine is stable enough for laminectomy alone.
Why it is done
Laminectomy is primarily a decompression surgery for stenosis, especially when standing and walking symptoms point to nerve crowding in the canal. It addresses the anatomy that is squeezing the nerves rather than simply masking the inflammation around them.
What happens in surgery
The surgeon removes part of the lamina and other compressive tissue to widen the canal and relieve pressure on the nerves. Additional work may also be done around the foramina if the exiting nerve roots need more space.
When fusion is added
Some patients can have a laminectomy alone, but others need fusion when instability, deformity, or a substantial vertebral slip is present. That choice depends on how much supporting structure must be removed and whether the segment is already unstable before surgery begins.
Recovery and goals
The main goal is improved walking tolerance, reduced leg pain, and less nerve-related heaviness or numbness. Recovery depends on the severity of stenosis, the presence of weakness, and whether the operation was a decompression only or part of a larger reconstruction.
