Lumbar Laminotomy/Foraminotomy for Bone Stenosis
(and for some other nerve compression problems)

Minimally invasive lumbar spine surgery is best done at the Back Institute because our technique targets the exact problem. Many centers do spine surgery in an exploratory manner, cutting apart and removing normal, important parts of the spine when it is not actually necessary to do so. At the Back Institute, we do exactly what needs to be done for the patient, and no more.

These procedures are alternatives to major spine operations (fusion, etc.)


Laminotomy is a spinal decompression surgery involving the lamina, a bony layer that covers and protects the spinal canal and spinal cord.

Below are some spinal conditions that may be treated with a laminotomy (this is not an all-inclusive list):

  •  Ankylosing spondylitis
  • Degenerative disc disease
  • Spinal stenosis (if caused by bone
  • Spondylosis (also known as spinal osteoarthritis)
  • Cyst
  • Ligamentous hypertrophy
  • Some disc herniations


Foraminotomy is an operation used to relieve pressure on nerves that are being compressed by bone in the intervertebral foramina; that is, the passages through the bones of the vertebrae that pass nerve bundles to the body from the spinal cord.

A foraminotomy is performed to relieve the symptoms of nerve root compression, in cases where the foramen is being compressed by bone or excessive ligament development and results in a pinched nerve.
