Methods of treatment for radiculopathy include conservative methods like rest, manipulation, NSAIDS, opioids and surgeries like laminectomy, laminotomy
and fenestration procedures.
Minimally invasive techniques such as tubular unilateral laminotomy
for bilateral decompression (ULBD) have been shown to provide comparable outcomes with open techniques with less overall morbidity.

A posterior approach with posterior laminectomy was performed in most cases, while in the last few years posterior laminotomy
was used in some of them (see below).

and en bloc resection of the lesion.

A unilateral laminotomy
and partial facetectomy were performed on the side consistent with the patient's symptoms or anatomical abnormalities.
This new code covers endoscopic decompression of the spinal cord, nerve root(s), including laminotomy
, partial facetectomy, foraminotomy, discectomy and/or excision of herniated intervertebral disc, 1 interspace, lumbar, and will be enforced as of January 1st, 2017.
During this procedure, a multilevel laminotomy
is performed from the L2-S1 level, the cauda equina is exposed and the dorsal root is separated from the ventral root.
