Spine Crack Treatment

[Irmgard Rossie]

Yournerve roots may become irritated and swollen at the spots where they are being pinched. Injecting a steroid medicine into the space around the pinched nerve may help reduce the swelling and relieve some of the pain.

However, steroid shots may not be the best choice for spinal stenosis. Some studies have shown that combined injections of steroids and a numbing medicine relieve back pain no better than shots of numbing medicine alone.

This is important because steroids can cause serious side effects. Repeated steroid injections can weaken nearby bones, tendons and ligaments. That's why a person often must wait many months before getting another steroid injection.

Sometimes, the ligament at the back of the lower spine, also called the lumbar spine, gets too thick. Needlelike tools inserted through the skin can remove some of the ligament. This can create more space in the spinal canal to reduce pressure on nerve roots. You may be given medicine to help you feel calm during the procedure. Many people can go home the same day.

A laminotomy removes only a portion of the lamina, the back part of a spinal bone. It carves a hole just big enough to relieve the pressure in a specific spot. While shown here on the neck, the surgery also can be done in the lumbar spine.

Laminoplasty is done only on the spinal bones in the neck. It increases the space within the spinal canal by creating a hinge on the lamina, the back part of a spinal bone. Metal hardware bridges the gap in the opened section of the spine.

You might be referred to a doctor who specializes in disorders of the nervous system, called a neurologist. Depending on how serious your symptoms are, you also may need to see a spinal surgeon, which could be a neurosurgeon or an orthopedic surgeon.

Pain caused by cancer that has spread, or metastasized, to the spine is a major problem for many patients. New findings from a clinical trial indicate that, for some patients with painful spinal metastases from advanced cancer, a type of precise, high-dose radiation therapy may be a highly effective way to relieve that pain.

About a third of people in the clinical trial who received this form of radiation therapy, called stereotactic body radiation therapy, or SBRT, for spinal metastases were pain-free up to 6 months after treatment, compared with only about 15% of people who received conventional external beam radiation therapy to treat the pain.

In recent years, because it can more precisely target tumors, SBRT has come to be widely used for people with only a few, small metastatic tumors (known as oligometastatic cancer), including those in the spine, he added. Some studies have shown that if these few metastases can be successfully treated, patients may live for years or decades.

Because of their potentially good prognosis, people with oligometastatic cancer were thought to be more likely than people with advanced metastatic disease to benefit from SBRT, which is more expensive and has a higher risk of causing some types of damage in the spine than conventional radiation therapy, Dr. Sahgal explained.

But the limitations of conventional radiation therapy as a palliative treatment for people with advanced cancer and spinal metastases eventually led researchers to wonder if SBRT might also be a better option for people with limited life expectancy.

The new trial was conducted by the Canadian Cancer Trials Group, part of NCI's National Clinical Trials Network. It included about 200 people who had three or fewer spinal metastases in a concentrated area of the spine that were the sole source of their pain. None had measurable signs of instability in the bones of the spine, which would increase the risk of fracture and make it harder to assess pain.

Measurements of spinal stability after 6 months were about the same in both groups. The risk of compression fractures was also similar in both groups, and the risk of serious fractures was minimal, the researchers reported. There were also no reports of damage to the spinal cord caused by the radiation treatments.

Spinal pain in the lumbar region (lower back) and cervical region (neck) are highly prevalent and are often the causes for many lost work days. Lumbar muscle strains and sprains are the most common causes of low back pain. The thoracic spine can also be a site of spinal pain, but because it is much more rigid, the thoracic spinal area is much less frequently injured than the lumbar and cervical spine.

When the lumbar spine is strained or sprained, the soft tissues become inflamed. This inflammation causes pain and may cause muscle spasms. Even though lumbar strain or sprain can be very debilitating, neither usually requires neurosurgical attention.

Spinal pain can be caused by things more severe that might require surgical consideration. These usually involve spinal pain that radiates into arms, legs or around the rib cage from back toward the anterior chest.

Non-surgical low back, cervical and thoracic pain usually affects the central or para-spinal soft tissue without radiating into the arms, around the chest or down the legs. On the contrary, pain radiating from the spine into the extremities or chest wall implies structural pinching of the nerves in the spine that might require a surgical opinion if the situation fails to improve within days to weeks with non-surgical symptomatic treatment.

Herniated Disc Symptoms

Symptoms vary greatly depending on the position of the herniated disc and the size of the herniation. If the herniated disc is not pressing on a nerve, the patient might experience spinal pain (cervical, lumbar and/ or thoracic) or no pain at all. If there is pressure on a nerve, there can be pain, numbness or weakness in the area of the body to which the nerve travels. Typically, a herniated disc is preceded by an episode of spinal pain (cervical, lumbar and/or thoracic) or a long history of intermittent episodes of spinal pain.

Diagnostic testing is usually necessary only when the pain has been present for more than two weeks and has not improved as expected. Likewise, if pain radiates into the extremities or around the chest well past the spinal epicenter of the pain focus, it is important to rule out underlying causes such as an undetected spinal disc injury. If symptoms are persistent, the following tests may be ordered by your doctor. It is important to note that regardless of diagnosis, an improving clinical picture supports continuing with nonsurgical modalities. If the improvement fails to reach a satisfactory stable point additional diagnostic efforts should be pursued. Likewise, if clinical symptoms deteriorate the diagnostic evaluation needs to be extended.

This should be as brief as possible, as prolonged bed rest can lead to a loss of muscle strength and may increase muscle stiffness, adding to pain and discomfort. Initial medical treatment is commonly comprised of nonsteroidal anti-inflammatory (NSAIDs) medication if the pain is mild to moderate. Muscle relaxants and narcotic medication can be added or substituted for cases of more severe pain symptoms.

A single excessive strain or injury may cause a herniated disc. However, disc material degenerates naturally as people age, and the ligaments that hold it in place begin to weaken. As this degeneration progresses, a relatively minor strain or twisting movement can cause a disc to rupture.

Certain individuals may be more vulnerable to disc problems and, as a result, may suffer herniated discs in several places along the spine. Research has shown that a predisposition for herniated discs may exist in families, with several members affected. This does not necessarily mean that disc disease is a hereditary condition but it can run in families.

The surgeon will give the patient specific instructions following surgery and usually will prescribe pain medication. Sometimes a spinal brace will be applied for weeks to months depending on the specific postsurgical needs. The surgeon will help determine when normal activities such as returning to work, driving and exercising may resume. Some patients may benefit from supervised rehabilitation or physical therapy after surgery. Such treatment will usually require a referral.

Discomfort is expected while the patient gradually return to normal activity, but pain is a warning signal that the patient might need to slow down. In general, continued gradual improvement is the expected trend over the first three or more months following surgery. The surgeon will provide prognostic information and give an idea of how to determine what adverse post-operative trends necessitates scheduling an unplanned re-evaluation. Such adverse trends would include fever, chills, wound drainage, new weakness, sensory or pain symptoms.

Finally, a patient needs to know beforehand that there usually are no absolutes regarding medical or surgical treatment of spinal conditions. Every patient is unique. It can be confusing which treatment or which elective operation is best in each situation. That is why patients have to rely on choosing a physician carefully. This applies to non-surgeons as well as surgeons. Pick a doctor that the patient feels comfortable with regardless of ultimate outcome. The best physicians are the ones that a patient can trust to tough it out with them when the treatment outcome fails to be ideal.

Artificial disc surgery (disc arthroplasty)

Surgical replacement of a diseased or herniated cervical or lumbar disc with an artificial disc designed to maintain spinal mobility. These usually consist of a plastic core between two metallic (usually titanium) plates that lock into the spine (see Figures 1, 2 and 3).
