Using an endoscope, the standard interlaminar window can be used to decompress central, lateral, and
foraminal stenosis (Fig.
As reported in several radiological and cadaveric studies, IPDs have an effect on soft central and
foraminal stenosis, because their action is effective on ligamentous buckling and hypertrophy, with good clinical results on neurogenic claudication in the early stage of the postoperative period.
Foraminal stenosis, by contrast, typically causes one-sided leg pain.

foraminal (BERNAL et al., 2003).
"Influenced by the initial success of XLIF ACR, ALIF ACR provides a procedurally integrated solution to restore the natural anterior column while increasing
foraminal height in the lower levels of the lumbar spine," said Pat Miles, President of Global Products and Services.
Currently, a method was introduced in Korea which uses a transforaminal balloon to treat lateral
foraminal stenosis.
To perform foraminotomy, we first titled the cannula to expose the
foraminal epidural space.
New diagnostic technology is now able to demonstrate that many cases of sciatica are in fact due to causes unrelated to disc lesions such as piriformis syndrome and distal
foraminal impingements.
Impingement has also been implicated as a cause of failed back surgery syndrome due to unrecognized or possibly inadequate treatment of
foraminal stenosis [4].
The spinal canal narrowing can be central, lateral, or
foraminal. Central canal stenosis causes narrowing to the cauda equina nerve roots because of facet joint hypertrophy, ligamentum flavum thickening, spondylolisthesis, or intervertebral disc herniation (Stuber, Sajko, & Kristmanson, 2009).
In addition to non-smokers, patients who didn't lift on the job, and those with
foraminal stenosis, predominant leg pain, or lower levels of disability saw greater improvements with surgery, the researchers reported.
