What is Spinal Stenosis?

Spinal stenosis is a narrowing of the spinal canal or the foramen, the opening through which nerve roots pass. Stenosis can develop in any area of the spine.

Degenerative changes in the spine, a collapsed disc, bone spurs, or cysts can cause the spinal canal to narrow. This narrowing places pressure on the nerve roots and/or spinal cord, often resulting in pain.

What Is Cervical Spinal Stenosis?

Cervical spinal stenosis is the narrowing of the spinal canal in the neck. The spinal canal can squeeze and compress the nerve roots where they leave the spinal cord which or it may compress the spinal cord itself. Squeezing the nerves and cord in the cervical spine can change how the spinal cord functions. The spinal cord is the nerves that allow us to feel, move, and control the bowel and bladder as well as other body functions.

Cervical Spinal Stenosis Symptoms

  • Stiffness in neck
  • Weakness in arms causing difficulty using the hands
  • Pain and Numbness in hands and/or arms

What Causes Cervical Spinal Stenosis?

Cervical Stenosis most common factors include:

  • Arthritic changes in neck
  • Bone spurs push on nerves and spinal cord
  • Large disc herniations

What Is Lumbar Spinal Stenosis?

Lumbar spinal stenosis is when the spinal nerves in the lower back are compressed, which often leads to leg pain and other symptoms.

Lumbar Spinal Stenosis Symptoms

  • Tired, heavy feeling in back, buttocks, and legs while walking or standing
  • Cramping sensation in these areas
  • Decreased walking due to weakness, numbness or pain in legs

What Causes Lumbar Spinal Stenosis?

Lumbar stenosis is normally caused by degenerative changes limiting nerve space. The lack of blood supply induces symptoms.

Spinal Stenosis Treatment Options

Non-Operative Treatment

Medications, physical therapy or spinal cortisone injections are indicated for pain relief. Surgery can be considered for those who do not improve.

Cervical Laminectomy

Spinous process and lamina are removed to decrease pressure on the spinal cord. Instrumentation can be used to ensure stability.

Lumbar Decompression

This procedure involves removing all or portions of the lamina, removing bone spurs and/or enlarging foramen to relieve pressure or compression on the nerve roots or spinal cord. This pressure often is the cause of the pain.

Decompression & Posterolateral Fusion

Often times, in addition to a decompression, your surgeon will perform an instrumented posterolateral fusion by inserting a series of screws and rods coupled with the placement of a bone graft. This fusion provides increased spinal stability.

Anterior Lumbar Interbody Fusion (ALIF)

The surgical approach is from the front of the abdomen. Once the exposure is made, the disc material causing the nerve compression is removed. After removal, an interbody cage or bone spacer is placed at the disc site filled with bone graft. The vertebral bodies above and below are frequently put under compression to aid in the subsequent spinal fusion.

Posterior Transforaminal Interbody Fusion

The same procedure as the ALIF but the approach and exposure are performed from the back. Just as in an ALIF, the disc material is removed and an interbody device is inserted. Compression through the use of pedicle screws is frequently achieved to aid in fusion.
