Even More Back Pain Treatments

Transcutaneous Electrical Nerve Stimulation (TENS): TENS involves wearing a small box over the painful area that directs mild electrical impulses to nerves there. The theory is that stimulating the nervous system can modify the perception of pain. Early studies of TENS suggested it could elevate the

levels of endorphins, the body’s natural pain-numbing chemicals, in the spinal fluid. But subsequent studies of its effectiveness against pain have produced mixed results.

Acupuncture: This ancient Chinese practice has been gaining increasing acceptance and popularity in the United States. It is based on the theory that a life force called Qi (pronounced chee)

flows through the body along certain channels, which if blocked can cause illness. According to the theory, the insertion of thin needles at precise locations along these channels by practitioners can unblock the flow of Qi, relieving pain and restoring health.

Although few Western-trained doctors would agree with the conept of blocked Qi, some believe

that inserting and then stimulating needles (by twisting or passing a low-voltage electri­cal current through them) may foster the production of the body’s natural pain-numbing chemicals, such as endorphins, serotonin, and acetylcholine.

A consensus panel convened by the National Institutes of Health (NIH) in 1997 concluded that there is clear evidence this treatment is effective for some pain conditions, including postoperative dental pain. Although there is less convincing evidence to support using acupuncture for back pain and some other pain conditions, the panel concluded that acupuncture may be effective when used as part of a comprehensive treatment plan for low back pain, fibromyalgia, and several other conditions.

Acupressure: As with acupuncture, the theory behind acupressure is that it unblocks the flow of Qi. The difference between acupuncture and acupressure is that no needles are used in acupressure. Instead, a therapist applies pressure to points along the channels with his or her hands, elbows, or even feet. (In some cases, patients are taught to do their own acupressure.) Acupressure has not been well studied for back pain.

Rolfing: A type of massage, rolfing involves using strong pressure on deep tissues in the back to relieve tightness of the fascia, a sheath of tissue that covers the muscles, that can cause or contribute to back pain. The theory behind rolfing is that releasing muscles and tissues from the fascia enables the back to prop­erly align itself. So far, the usefulness of rolfing for back pain has not been scientifically proven.

Operative treatments

Depending on the diagnosis, surgery may either be the first treatment of choice – although this is rare – or it is reserved for chronic back pain for which other treatments have failed. If you are in constant pain or if pain reoccurs frequently and interferes with your ability to sleep, to function at your job, or to perform daily activities, you may be a candidate for surgery.

In general, there are two groups of people who may require surgery to treat their spinal problems. People in the first group have chronic low back pain and sciatica, and they are often diagnosed with a herniated disc, spinal stenosis, spondylolisthesis, or vertebral fractures with nerve involvement. People in the second group are those with only predominant low back pain (without leg pain). These are people with discogenic low back pain (degener­ative disc disease), in which discs wear with age. Usually, the outcome of spine surgery is much more predictable in people with sciatica than in those with predominant low back pain.

Some of the diagnoses that may need surgery include:

Herniated discs: a potentially painful problem in which the hard outer coating of the discs, which are the circular pieces of connective tissue that cushion the bones of the spine, are damaged, allowing the discs’ jelly-like center to leak, irritating nearby nerves. This causes severe sciatica and nerve pain down the leg. A herniated disc is some­times called a ruptured disc.

Spinal stenosis: the narrowing of the spinal canal, through which the spinal cord and spinal nerves run.

It is often caused by the overgrowth of bone caused by osteoarthritis of the spine. Compression of the nerves caused by spinal stenosis can lead not only to pain, but also to numbness in the legs and the loss of bladder and/or bowel control. Patients may have difficulty walk­ing any distances and may also have severe pain in their legs along with numbness and tingling.

Spondylolisthesis: a condition in which a vertebra of the lumbar spine slips out of place. As the spine tries to stabi­lize itself, the joints between the slipped vertebra and adjacent vertebrae can become enlarged, pinching nerves as they exit the spinal column. Spondylolisthesis may cause not only low back pain but severe sciatica leg pain.

Vertebral fractures: fractures caused by trauma to the vertebrae of the spine or by crumbling of the vertebrae resulting from osteoporosis. This causes mostly mechani­cal back pain, but it may also put pressure on the nerves, creating leg pain.

Discogenic Low Back Pain (Degenerative Disc Disease): Most people’s discs degenerate over a lifetime, but in some, this aging process can become chronically painful, severely interfering with their quality of life.

Following are some of the most commonly performed back surgeries:

For herniated discs:

Laminectomy/discectomy: In this operation, part of the lamina, a portion of the bone on the back of the vertebrae, is removed, as well as a portion of a ligament. The herni­ated disc is then removed through the incision, which may extend two or more inches.

Microdiscectomy: As with traditional discectomy, this procedure involves removing a herniated disc or damaged portion of a disc through an incision in the back. The dif­ference is that the incision is much smaller and the doctor uses a magnifying microscope or lenses to locate the disc through the incision. The smaller incision may reduce pain and the disruption of tissues, and it reduces the size of the surgical scar. It appears to take about the same time to recuperate from a microdiscectomy as from a tradi­tional discectomy.

Laser surgery: Technological advances in recent decades have led to the use of lasers for operating on patients with herniated discs accompanied by lower back and leg pain. During this procedure, the surgeon inserts a needle in the disc that delivers a few bursts of laser energy to vaporize the tissue in the disc. This reduces its size and relieves pressure on the nerves. Although many patients return

to daily activities within 3 to 5 days after laser surgery, pain relief may not be apparent until several weeks or even months after the surgery. The usefulness of laser discectomy is still being debated.

For spinal stenosis:

Laminectomy: When narrowing of the spine compresses the nerve roots, causing pain and/or affecting sensation, doctors sometimes open up the spinal column with a pro­cedure called a laminectomy. In a laminectomy, the doc­tor makes a large incision down the affected area of the spine and removes the lamina and any bone spurs, which are overgrowths of bone, that may have formed in the spinal canal as the result of osteoarthritis. The procedure is major surgery that requires a short hospital stay and physical therapy afterwards to help regain strength and mobility.

For spondylolisthesis:

Spinal fusion: When a slipped vertebra leads to the enlargement of adjacent facet joints, surgical treatment generally involves both laminectomy (as described above) and spinal fusion. In spinal fusion, two or more vertebrae are joined together using bone grafts, screws, and rods to stop slippage of the affected vertebrae. Bone used for grafting comes from another area of the body, usually

the hip or pelvis. In some cases, donor bone is used.

Although the surgery is generally successful, either type of graft has its drawbacks. Using your own bone means surgery at a second site on your body. With donor bone, there is a slight risk of disease transmission or rejection. In recent years, a new development has eliminated those risks for some people undergoing spinal fusion: proteins called bone morphogenic proteins are being used to stim­ulate bone generation, eliminating the need for grafts. The proteins are placed in the affected area of the spine, often in collagen putty or sponges.

Regardless of how spinal fusion is performed, the fused area of the spine becomes immobilized.

For vertebral osteoporotic fractures³:
Vertebroplasty: When back pain is caused by a compression fracture of a vertebra due to osteoporosis or trauma, doctors may make a small incision in the skin over the affected area and inject a cement-like mixture called polymethyacrylate into thefractured vertebra to relieve pain and

stabilize the spine. The procedure is generally performed on an outpatient basis under a mild anesthetic.

Kyphoplasty: Much like vertebroplasty, kyphoplasty is used to relieve pain and stabilize the spine following fractures due to osteoporosis. Kyphoplasty is a two-step process. In the first step, the doctor inserts a balloon device to help restore the height and shape of the spine. In the second step, he or she injects polymethyacrylate to repair the fractured vertebra. The procedure is done under anesthesia, and in some cases it is performed on an out­patient basis.

For Discogenic Low Back Pain (Degenerative Disc Disease)

Intradiscal electrothermal therapy (IDT): One of the newest and least invasive therapies for low back pain involves inserting a heating wire through a small incision in the back and into a disc. An electrical current is then passed through the wire to strengthen the collagen fibers that hold the disc together. The procedure is done on an outpatient basis, often under local anesthesia. The useful­ness of IDT is debatable.

Spinal fusion: When the degenerated disc is painful, the surgeon may recommend removing it and fusing the disc to help with the pain. This fusion can be done through the abdomen, a procedure known as anterior lumbar inter- body fusion, or through the back, called posterior fusion. Theoretically, fusion surgery should eliminate the source of pain; the procedure is successful in about 60 to 70 per­cent of cases. Fusion for low back pain or any spinal surgeries should only be done as a last resort, and the patient should be fully informed of risks.

Disc replacement: When a disc is herniated, one alter­native to a discectomy – in which the disc is simply removed – is removing it and replacing it with a synthetic disc. Replacing the damaged one with an artificial one restores disc height and movement between the vertebrae. Artificial discs come in several designs. Although doctors in Europe had performed disc replacement for more than a decade, the procedure had been experimental in the United States until the Food and Drug Administration approved the Charite artificial disc (http://www.fda.gov/ cdrh/mda/docs/p040006.htm) for use.
