Lumbar Stenosis

Lumbar stenosis is a condition that can often stems from age-related changes in the spine. Knowing what causes lumbar stenosis and your treatment options is an important step toward relief.

Lumbar stenosis occurs when the spinal canal in the lower back narrows, putting pressure on the nerves that travel to the hips and legs. This narrowing typically develops gradually as the spine changes with age or can be caused acutely by trauma such as a herniated disc or with fracture.

Most people describe lumbar stenosis as lower back pain along with numbness, tingling, or weakness in the legs. These symptoms often worsen with standing, walking, sitting, or bending forward. In more advanced cases, it can also affect balance or the ability to walk long distances.

POSH specialists offer a range of treatments to help patients manage lumbar stenosis, including both nonsurgical and surgical options tailored to each patient’s individual needs.

Lumbar stenosis typically develops when age-related changes narrow the spinal canal in the lower back. Common causes include:

  • Age-related wear and disc degeneration
  • Bone spurs that form along the spine
  • Thickened ligaments within the spinal canal
  • Herniated or bulging discs
  • Spondylolisthesis, or a slipped vertebra
  • Fractured vertebrae with bone that compresses the spinal canal

Diagnosing lumbar stenosis starts with a thorough evaluation by a POSH spine specialist. Our specialists typically evaluate patients by:

  • Physical exam: Our specialists will review your medical history and assess your strength, reflexes, and range of motion to help identify the underlying cause.
  • Imaging tests. X-rays, MRI or CT scans give our specialists a detailed look at the disc and surrounding structures, helping confirm a diagnosis.

POSH specialists work alongside a multidisciplinary team to deliver nonsurgical treatments for lumbar stenosis. These conservative approaches are often the first step toward relief before surgical recommendations.

  • Physical therapy
  • Anti-inflammatory medications (ibuprofen or acetaminophen)
  • Activity modification
  • Prescriptive medication
  • Bracing when appropriate (i.e., spinal fractures)

When nonsurgical methods don’t provide sufficient relief, a POSH specialist will discuss surgical options, which may include:

  • Laminectomy: A procedure that removes a part of the supporting vertebra to create more space and relieve pressure on the affected nerves.
  • Spinal fusion: Stabilizes the spine by fusing two or more vertebrae together, often performed alongside a laminectomy for added support.
  • Minimally Invasive Laminoforaminotomy: A procedure that removes a targeted portion of the spine that is creating pressure on the surrounding neural tissue. Unlike a laminectomy, where a larger portion of the supporting structures are removed, the goal of a laminoforaminotmy is to remove only the material that is compressive and to do so through a small enough incision that doesn’t disrupt surrounding supportive structures such as muscle, tendons, or joints.
