Laminectomy for discectomy is performed by those neurosurgeons or orthopaedic surgeons who are not comfortable with operating through small incisions that is involved in performing microdiscectomy or endoscopic discectomy. It involves removal of a part of the bone of the spine called the lamina. Most spine surgeons prefer not to remove bone while doing discectomy as it may lead to spinal instability at later date. Laminectomy involves larger muscle dissection, removal of ligaments which support the spine as well as bone removal (laminectomy) resulting in weakening of the spine causing spinal instability (listhesis) or chronic back pain.
