Microdiscectomy (or microdecompression) is a minimally invasive surgical procedure in which a portion of a herniated nucleus pulposus is removed by way of a surgical instrument. [2] The purpose of this procedure is to relieve the pressure and reduce the local inflammatory reaction around a nerve root, caused by the herniated nucleus pulposus.
A discectomy (also called open discectomy, if done through a 1/2 inch or larger skin opening) is the surgical removal of abnormal disc material that presses on a nerve root or the spinal cord. The procedure involves removing a portion of an intervertebral disc , which causes pain, weakness or numbness by stressing the spinal cord or radiating ...
Anterior cervical discectomy and fusion (ACDF) is a surgical procedure to treat nerve root or spinal cord compression by decompressing the spinal cord and nerve roots of the cervical spine with a discectomy, followed by inter-vertebral fusion to stabilize the corresponding vertebrae. [1]

The first blind transforaminal discectomy was done by Parvis Kambin in 1973 with Craig's canula's. The Tessys method was a further development of the existing YESS method (American Anthony Yeung ) by the Dutch Thomas Hoogland in 1989 in Munich by reaming a few mm's from the SAP (Superior Articular Process).
In cases where the nerve has been damaged but is still capable of regrowth, recovery time is widely variable. Surgical intervention with decompression of the cauda equina can assist recovery. Delayed or severe nerve damage can mean up to several years' recovery time because nerve growth is exceptionally slow. [citation needed]
A nerve decompression is a neurosurgical procedure to relieve chronic, direct pressure on a nerve to treat nerve entrapment, a pain syndrome characterized by severe chronic pain and muscle weakness. In this way a nerve decompression targets the underlying pathophysiology of the syndrome and is considered a first-line surgical treatment option ...
It may be beneficial in understanding the changes that occur after herniated lumbar disc compresses a nerve root, and might help in differentiating the patients that need surgical intervention. In patients with a high suspicion of radiculopathy due to lumbar disc herniation, yet the MRI is equivocal or negative, nerve conduction studies are ...
