Today, microdiscectomy is one of the most common lumbar surgical procedures performed to remove a herniated disc. Microdiscectomy involves a small incision at the appropriate lumbar level and use of an operating microscope. Using microscopic magnification, a small opening in the spine’s bony lamina, laminotomy, is made and the disc is removed using ultramodern microsurgical techniques.

When appropriate, Boulder Neurosurgical Associates’ neurosurgeons may use laser technology to complete the microdiscectomy.


Laminectomy is a procedure that is commonly performed to treat lumbar spinal stenosis. It involves removing the spinous process (bony projection from the back of the vertebral body), lamina (bony covering the spinal canal), and part of the facet joints.

Often, laminectomy may be combined with another procedure, foraminotomy and can be performed using minimally invasive surgical techniques. The neurosurgeons at Boulder Neurosurgical & Spine Associates emphasize the minimally invasive approach and use of the operating microscope to enhance visualization of the spine’s anatomy. This treatment is very effective for spinal stenosis.


A lumbar foraminotomy involves decompressing lumbar spinal nerve roots by removing tissue and enlarging the size of the foramen. This procedure is performed to treat foraminal stenosis. A foraminotomy may be combined with discectomy or laminectomy, all of which may be performed using minimally invasive techniques.
