Lumbar Laminectomy – also known as an open decompression – is performed to alleviate the pain caused by neural impingement that results from lumbar spinal stenosis and is caused by the degenerative changes causing enlargement of the facet joints. The joints put a lot of pressure on the nerves and this pressure can be effectively relieved with the help of laminectomy.
Laminectomy is the treatment of removing the portion of the enlarged facet joint and the thickened ligaments. It is done by removing a small portion of the bone over the nerve root. This gives the nerve root more space and a better healing environment. Doctors prefer Laminectomy only when the symptoms are severe and show excessive weakening.
