2. Failed back syndrome - Wikipedia

   en.wikipedia.org/wiki/Failed_back_syndrome

   CT scan image of large herniated disc in the lumbar spine. Removal of a disc at one level can lead to disc herniation at a different level at a later time. Even the most complete surgical excision of the disc still leaves 30–40% of the disc, which cannot be safely removed. This retained disc can re-herniate sometime after surgery.

3. Laminectomy - Wikipedia

   en.wikipedia.org/wiki/Laminectomy

   The recovery period after a laminectomy depends on the specific operative technique, with minimally invasive procedures having significantly shorter recovery periods than open surgery. Removal of substantial amounts of bone and tissue may require additional procedures such as spinal fusion to stabilize the spine and generally require a much ...

4. Laminotomy - Wikipedia

   en.wikipedia.org/wiki/Laminotomy

   A laminotomy is an orthopaedic neurosurgical procedure that removes part of the lamina of a vertebral arch in order to relieve pressure in the vertebral canal. [1] A laminotomy is less invasive than conventional vertebral column surgery techniques, such as laminectomy because it leaves more ligaments and muscles attached to the spinous process intact and it requires removing less bone from the ...

5. Spinal decompression - Wikipedia

   en.wikipedia.org/wiki/Spinal_decompression

   Laminectomy is an open or minimally invasive surgical procedure in which a portion of the posterior arch of the vertebrae and/or spinal ligaments is removed from the spine to alleviate the pressure on the spinal canal contents. This procedure is usually performed when decompression of more than one nerve root is needed.

6. Laminoplasty - Wikipedia

   en.wikipedia.org/wiki/Laminoplasty

   The name was given due to the z-shape formed when cutting the laminae. The next method is called, en bloc laminoplasty, and it was a modification of the en bloc laminectomy, which was developed by Tsuji. En bloc laminoplasty decompresses the spine by making the laminae act as a flap, and this flap hovered over the cord without sutures or bone ...

7. Lumbar spinal stenosis - Wikipedia

   en.wikipedia.org/wiki/Lumbar_spinal_stenosis

   In myelopathy (pathology of the spinal cord) from degenerative changes, the findings are usually permanent and decompressive laminectomy will not reverse the pathology. Surgery can stop the progression of the condition. In cases where the MRI changes are due to vitamin B 12 deficiency, a brighter prospect for recovery can be expected. [22] [23 ...
