How is Spinal Stenosis Diagnosed?

Lumbar spinal stenosis is a narrowing of the spinal canal in the lower part of your back. Stenosis, which means narrowing, can cause pressure on your spinal cord or the nerves that go from your spinal cord to your muscles. Spinal stenosis can happen in any part of your spine but is . Lumbar spinal stenosis is a narrowing of the spinal canal, compressing the nerves traveling through the lower back into the legs. While it may affect younger patients, due to developmental causes, it is more often a degenerative condition that affects people who are typically age 60 and older.

The site navigation utilizes arrow, enter, escape, and space bar key commands. Up and Down arrows will open main level menus and toggle through sub tier links. Enter and space open menus and escape closes them as well. Tab will move on to the next part of the site what is spinal stenosis of lumbar spine than go through splne items.

The lumbar spine lower back consists of five vertebrae in wwhat lower part of the spine, between the ribs and the pelvis. Lumbar spinal stenosis is a spnial of the spinal canal, compressing the nerves traveling through the lower back into the legs. While it may affect younger patients, due to developmental causes, it is more often a degenerative condition that affects people who are typically age 60 and older.

Narrowing of the spinal canal usually occurs slowly, over many years or decades. How to design your own sneakers disks become less spongy with aging, resulting in loss of disk height, and may cause bulging of the hardened disk into the spinal canal. Bone spurs may also occur and ligaments may thicken. All of these can contribute to narrowing of the central canal and may or may not produce symptoms.

Symptoms may be due to inflammation, sstenosis of the tsenosis s or both. Such symptoms may include:. Degenerative spondylolisthesis and degenerative scoliosis curvature of the spine are two conditions that may be associated with lumbar spinal stenosis.

Degenerative spondylolisthesis slippage of how to burn iso files to dvd on mac vertebra over another is caused by osteoarthritis of the facet joints. Most commonly, it involves the L4 slipping over the L5 vertebra. Degenerative scoliosis occurs most frequently in the lower back and more commonly affects people aged 65 and older. Back pain associated with degenerative scoliosis usually begins gradually and is linked with activity.

The curvature spinf the spine in this form of scoliosis is often relatively minor. Surgery may be indicated when nonsurgical measures fail spinf improve pain associated with the condition. Diagnosis is made by a neurosurgeon based on history, symptoms, physical examination and test results. A combination of time, medications, posture management, psine and exercise can be helpful to many patients for pain flare-ups.

Weight management, nicotine cessation and bone-strengthening endeavors may also be indicated. A doctor may recommend surgery if non-surgical management as described above does not improve symptoms. There are different types of spinal surgeries available, and depending on the specific case, a neurosurgeon will help to determine what procedure might be appropriate for the patient. There are several different surgical procedures that can be utilized, the stenosls of which is influenced by the severity of the case.

In a small percentage of patients, spinal instability may require that spinal fusion be performed — this decision generally is determined prior to surgery. Spinal fusion is an operation that creates a solid union between two or more vertebrae.

Spinal fusion may assist in strengthening and stabilizing the spine, and may thereby help to alleviate severe and chronic back pain. The most common surgery in the lumbar spine is called decompressive laminectomyin which the laminae roof of the vertebrae are removed to create more space for the spihal.

A neurosurgeon may perform a laminectomy with or without fusing vertebrae or removing part of a disk. A spinal fusion with or without spinal instrumentation may be used to enhance fusion and support sipnal areas of the spine. The potential benefits of surgery stensis always be weighed carefully against the risks of surgery and anesthesia. Although a large percentage of lumbar spinal stenosis patients who ultimately undergo surgery report significant pain relief after surgery, there is no guarantee that surgery will help every individual.

Lumbar canal stenosis is the narrowing of the spinal canal or the tunnels through which nerves and other structures communicate with that canal. Narrowing of the spinal canal usually occurs due to changes associated with aging that decrease the size of the canal, including the movement of one of the vertebrae out of alignment. The term "stenosis" is derived from Greek and refers to the process of narrowing that constricts or “chokes” the spinal nerves. The cause of spinal stenosis in the lumbar spine (lower back) is commonly associated with degenerative changes, also known as spondylosis, that occur as a result of aging. Lumbar Spinal Stenosis Video Save. Apr 22,  · Spinal stenosis is a condition that causes the spinal column to narrow and compresses the spinal cord. This does not happen quickly, but is a more gradual concern. Too much narrowing compresses the nerves in the spinal and causes problems.

To diagnose spinal stenosis, your doctor may ask you about signs and symptoms, discuss your medical history, and conduct a physical examination. He or she may order several imaging tests to help pinpoint the cause of your signs and symptoms. Our caring team of Mayo Clinic experts can help you with your spinal stenosis-related health concerns Start Here. Treatment for spinal stenosis depends on the location of the stenosis and the severity of your signs and symptoms.

Talk to your doctor about the treatment that's best for your situation. If your symptoms are mild or you aren't experiencing any, your doctor may monitor your condition with regular follow-up appointments.

He or she may offer some self-care tips that you can do at home. If these don't help, he or she may recommend medications or physical therapy. Surgery may be an option if other treatments haven't helped. It's common for people who have spinal stenosis to become less active, in an effort to reduce pain. But that can lead to muscle weakness, which can result in more pain. A physical therapist can teach you exercises that may help:.

Your nerve roots may become irritated and swollen at the spots where they are being pinched. While injecting a steroid medication corticosteroid into the space around impingement won't fix the stenosis, it can help reduce the inflammation and relieve some of the pain. Steroid injections don't work for everyone. And repeated steroid injections can weaken nearby bones and connective tissue, so you can only get these injections a few times a year. With this procedure, needle-like instruments are used to remove a portion of a thickened ligament in the back of the spinal column to increase spinal canal space and remove nerve root impingement.

Only patients with lumbar spinal stenosis and a thickened ligament are eligible for this type of decompression. The procedure is called percutaneous image-guided lumbar decompression PILD. It has also been called minimally invasive lumbar decompression MILD , but to avoid confusion with minimally invasive surgical procedures, doctors have adopted the term PILD.

Because PILD is performed without general anesthesia, it may be an option for some people with high surgical risks from other medical problems. A lumbar laminectomy involves the removal of the back portion of a vertebra in your lower back to create more room within the spinal canal.

A cervical laminectomy involves the removal of the back portion of a vertebra in your neck to create more room within the spinal canal. A laminotomy removes only a portion of the lamina, typically carving a hole just big enough to relieve the pressure in a particular spot. While shown here on the neck, it can also be performed in the lumbar spine. Laminoplasty is performed only on the vertebrae in the neck cervical spine. It opens up the space within the spinal canal by creating a hinge on the lamina.

Metal hardware bridges the gap in the opened section of the spine. Surgery may be considered if other treatments haven't helped or if you're disabled by your symptoms. The goals of surgery include relieving the pressure on your spinal cord or nerve roots by creating more space within the spinal canal. Surgery to decompress the area of stenosis is the most definitive way to try to resolve symptoms of spinal stenosis.

Research shows that spine surgeries result in fewer complications when done by highly experienced surgeons. Don't hesitate to ask about your surgeon's experience with spinal stenosis surgery. If you have any doubts, get a second opinion. This procedure removes the back part lamina of the affected vertebra. A laminectomy is sometimes called decompression surgery because it eases the pressure on the nerves by creating more space around them.

In some cases, that vertebra may need to be linked to adjoining vertebrae with metal hardware and a bone graft spinal fusion to maintain the spine's strength. Minimally invasive surgery. This approach to surgery removes bone or lamina in a way that reduces the damage to nearby healthy tissue. This results in less need to do fusions.

While fusions are a useful way to stabilize the spine and reduce pain, by avoiding them you can reduce potential risks, such as post-surgical pain and inflammation and disease in nearby sections of the spine. In addition to reducing the need for spinal fusion, a minimally invasive approach to surgery has been shown to result in a shorter recovery time. In most cases, these space-creating operations help reduce spinal stenosis symptoms.

But some people's symptoms stay the same or get worse after surgery. Other surgical risks include infection, a tear in the membrane that covers the spinal cord, a blood clot in a leg vein and neurological deterioration. Clinical trials are underway to test the use of stem cells to treat degenerative spinal disease, an approach sometimes called regenerative medicine. Genomic medicine trials are also being done, which could result in new gene therapies for spinal stenosis.

Integrative medicine and alternative therapies may be used with conventional treatments to help you cope with spinal stenosis pain. Examples include:. Explore Mayo Clinic studies testing new treatments, interventions and tests as a means to prevent, detect, treat or manage this condition. You'll have regular follow-up appointments with your doctor to monitor your condition. He or she may suggest that you incorporate several home treatments into your life, including:.

If your primary care doctor thinks you have spinal stenosis, he or she may refer you to a doctor who specializes in disorders of the nervous system neurologist.
