Lumbar spinal stenosis, a narrowing of the spinal canal, is a common cause of low back and leg pain, especially pain that gets worse with standing or walking and eases when sitting or bending forward.

For patients whose symptoms persist despite physical therapy, medications and injections, minimally invasive interspinous-interlaminar fixation offers an option between conservative care and open spine surgery. Through a small incision, a device is placed between the spinous processes at the affected level. It stabilizes the segment and gently holds the space open, which can relieve pressure on the nerves (an “indirect decompression”).

Compared with traditional open fusion, the procedure typically involves less tissue disruption, less blood loss and a quicker return to normal activities. It is performed on an outpatient basis at an ambulatory surgery center.

Not every patient is a candidate. A careful review of your history, examination and imaging (MRI, CT and X-rays) determines whether this approach is right for you. Ask Dr. Vargas whether a minimally invasive spine option may help your condition.
