Minimally invasive lumbar decompression achieves the same neurological goals as traditional open laminectomy — removing the tissue compressing lumbar nerve roots — through smaller incisions with less disruption of the surrounding muscles. For appropriately selected patients with lumbar stenosis causing leg pain, claudication, or neurological symptoms, MIS decompression offers equivalent decompression with faster recovery and less postoperative pain than traditional open surgery.

HOW IT WORKS

Traditional lumbar laminectomy requires a long midline incision and significant stripping of the paraspinal muscles off the spine. Minimally invasive techniques use one or two small incisions (typically 2–3 cm each) and a tubular retractor system that dilates the muscles rather than cutting them, providing access to the lamina and ligamentum flavum through a narrow working channel. The same decompression is achieved — removal of the thickened ligamentum flavum and portions of the laminae and facet joints compressing the nerve roots — with significantly less soft tissue damage.

CONDITIONS TREATED

  • Lumbar spinal stenosis causing neurogenic claudication — leg pain, heaviness, and weakness that worsen with walking or standing and improve with sitting or bending forward
  • Single or two-level lumbar stenosis without significant instability or deformity
  • Foraminal stenosis — compression of a nerve root as it exits the spinal canal
  • Recurrent stenosis after prior decompression (selected cases)

WHO IS A CANDIDATE?

MIS decompression is most appropriate for patients with focal stenosis at 1–2 levels without significant instability, spondylolisthesis requiring fusion, or deformity. Patients with multilevel stenosis, significant spondylolisthesis, or sagittal imbalance are better treated with open surgery and fusion, as MIS decompression alone does not address instability.

THE PROCEDURE

Performed under general anesthesia, typically taking 1–2 hours. One or two small incisions are made and a tubular retractor dilates the paraspinal muscles. Under microscopic or endoscopic visualization, the thickened ligamentum flavum is removed and the laminae trimmed to enlarge the spinal canal. A bilateral decompression can often be achieved through a unilateral approach by angling the retractor across the midline. Intraoperative fluoroscopy confirms level and position throughout.

RECOVERY

Most patients go home the same day or after one overnight stay. Return to light activity: 1–2 weeks. Return to physical work: 4–6 weeks. Most patients notice significant improvement in walking tolerance and leg symptoms within the first weeks after surgery.

FREQUENTLY ASKED QUESTIONS

Is MIS decompression less invasive in every case?

It’s less invasive for the specific patients it’s suited to, generally those with focal stenosis and no significant instability. For more complex multilevel disease or instability, open surgery with fusion may be the more appropriate and effective choice.

Does this procedure address spondylolisthesis?

Decompression alone does not stabilize a spondylolisthesis. If instability is present, fusion is generally needed in addition to decompression.

How much smaller is the incision?

Typically 2 to 3 centimeters per incision, compared to a longer midline incision for traditional open laminectomy.

Will my walking tolerance improve?

Most patients with neurogenic claudication notice meaningful improvement in walking distance within the first weeks after decompression, once the nerve compression is relieved.

Can stenosis come back after this procedure?

Recurrent stenosis at the same level is uncommon but possible over time, and can often be addressed with repeat decompression if it occurs.

WHY CHOOSE DR. SARDAR

Dr. Sardar selects between minimally invasive and open decompression based on what is genuinely best for each patient’s anatomy and pathology. He is trained in both approaches and recommends MIS decompression only when the patient’s anatomy and surgical goals are well-suited to it.
