About Low back

The back bears a heavy load; it supports the weight of the body, sustains the weight of objects that are lifted or carried, and absorbs the stresses that result when parts of the body move. The back is a complex combination of muscles, ligaments, tendons, and bones-all attached to the backbone. The backbone is a series of interconnected blocks of bone called vertebrae. They form a tube-like "vertebral canal" that contains and protects the spinal cord and its bundles of nerves.

Causes of Low-Back Pain

Low-back pain may be caused by abnormal development of the backbone, excessive stress on the back, injury, or any one of a number of physical disorders that affect the bones or the discs in the spine. The following are among the most common:

1. Ruptured or Herniated Disc. This is a frequent cause of low-back pain, and is sometimes called a "slipped" disc. Actually, an intervertebral disc cannot "slip" out of position. It can rupture, however, and when it does, some of the disc's fragments push backward (prolapse posteriorly) into the spinal canal and press on nearby nerves, causing pain, numbness, tingling, and sometimes weakness in the leg or foot. A disc may rupture after a relatively minor stress, such as bending over to pick up an object. Pain may occur immediately after the rupture occurs, or it may grow steadily worse over the next few minutes or hours. Pain from a ruptured disc may involve the center or one side of the back, and it spreads gradually to the leg. This leg pain, which may be accompanied by numbing or tingling sensations, may affect the thigh, the back or outside of the calf, or the edge or top of the foot. Called Sciatica, leg pain or numbness is caused by the pressure that the ruptured disc's fragments exert on the components of the sciatic nerve, which runs from the spinal cord down the thigh to the calf and foot. Each vertebra has a cylinder-shaped body, a vertebral arch, and several bony protuberances. The body of the vertebra rests on a cushion of tissue, known as an intervertebral disc that can act as a shock absorber. The vertebral arch extends from the body of the vertebra up and over the spinal cord to safeguard the spinal nerves. The bony protuberances are the places at which muscles, ligaments, tendons, and other bones join the backbone; they allow for normal flexibility of spinal movements.

2. Degeneration of the Vertebrae or Discs. Low-back pain occurs when parts of the vertebrae or the intervertebral disc deteriorate. When vertebral joints begin to wear down, the condition is called osteoarthritis. When the intervertebral discs start to degenerate, the spinal canal may become narrow and bone spurs can develop, a condition known as Spondylosis. Osteoarthritis and spondylosis produce intermittent aching or stiffness in the low back. Such low-back pain may spread into the buttocks and the thighs and may be aggravated by exercise or poor posture. People with osteoarthritis or spondylosis often feel stiff when they try to bend forward or stretch backward, because with these diseases, the backbone loses its mobility.

3. Spinal Stenosis. Narrowing of the vertebral canal is known as spinal stenosis. It may be due to overgrowth of vertebral joints associated with backward bulging of the discs or to degenerative diseases such as osteoarthritis or spondylosis (accompanied by thickening of the normal spinal ligaments). Pain from spinal stenosis, which typically occurs during walking or other exercise, develops after a few minutes of activity, accompanied by numbness, tingling, or cramps in the legs, and eases after a few minutes of rest

4. Sprains. Just as a sudden twist of the foot can cause a sprained ankle, an abrupt movement of the spine can sprain the muscles and ligaments of the back. A sprain is a partial tear of a ligament that has been overstretched. The pain from a sprain is located over the damaged ligament.

5. Infection. An infection in one part of the body, such as tuberculosis, can spread to the backbone and produce an inflammation of the bone or, occasionally, an abscess. Back pain from an infection develops slowly and eventually becomes severe. In addition to the back pain, a spinal infection raises the patient's temperature and brings on an overall feeling of weakness and bouts of chills. The pain is often associated with severe spasms and stiffness of the back.

6. Tumors. Spinal tumors are uncommon. They may arise in the vertebral column or within the spinal cord or nerve roots, or they may spread to the spine from cancer elsewhere in the body. Spinal tumors cause pain in the back and may produce weakness or numbness

7. Ankylosing Spondylitis. Ankylosing Spondylitis is an inflammation of the backbone that causes stiffness. It occurs mainly in men between the ages of 15 and 25. In the most severe form of the disease, the backbone becomes completely rigid. Initially, the low back is stiff and painful, and the pain is aggravated by rest. A person with Ankylosing Spondylitis will often awake with an aching and stiff back and will gain relief only by exercising.

Before an Operation is considered

Many of the conditions that bring about low-back pain (ankylosing spondylitis, sprains, osteoarthritis, and even a prolapsed disc) can be treated through rest, appropriate medication, and mild exercise. An operation is not considered, in fact, until these and sometimes other conservative measures have proved unsuccessful. If a trial period of conservative therapy produces unsatisfactory results and low-back pain continues to interfere with a person's day-to-day activities, an operation may be considered.

Even when an operation becomes a possibility, it will not be attempted until the spine has been carefully assessed. Before performing a surgical procedure, the surgeon must know the exact nature of the problem in the back. Consequently, he or she will study the back by means of X-rays or other tests, such as myelography, computerized axial tomography (CT), or magnetic resonance imaging (MRI).

In myelography, a radiopaque material is injected into the vertebral canal to outline any disorders that may be found in the vertebrae or discs. Usually, the patient is placed on a special table that makes it possible to change his or her position, thereby distributing the injected material up and down the vertebral canal. Because myelography may cause headaches, which can be aggravated by sitting up or standing, patients may be asked to remain in bed for a day after the test.

During CT, a patient is placed in a large, circular device that projects X rays through a cross-section of the body. The X-rays outline the densities of various tissues, and by analyzing these densities, a physician can detect abnormalities.

Magnetic resonance imaging (MRI) is a relatively new technique for showing the bones and other tissues of the body. MRI scans do not involve the use of X-rays, and they may or may not include the injection of a contrast agent in the vertebral canal to enhance the images seen by the physician. An advantage of this method is that soft tissues (such as ruptured discs) show up much better on an MRI scan than they do on an X-ray or a CT scan. The test takes a longer time to perform than an X-ray or CT, and the patient must lie quietly in a large magnetic tube for the time of the examination. However, this type of examination is proving to be a safe and highly effective way to diagnose spinal disorders.

In addition, electrical studies of the muscles and nerves may be useful in diagnosing and managing spinal disorders.

About Operations on the Back

The type of operation a surgeon performs depends on the nature of a patient's back problem. However, most procedures involve a Fenestration, which may require the partial removal of the vertebral arch to gain access to the cause of the patient's low-back pain. If a disc has ruptured, a surgeon will perform a Microdiscectomy to investigate the vertebral canal, identify the ruptured disc, and remove a good portion of the degenerated disc material, especially those fragments that press on the nerve roots.

The surgeon may consider a second procedure-Spinal Fusion-if he or she feels that stabilization of the spine is necessary. A spinal fusion is performed by fusing the vertebrae together with bone grafts; sometimes, the grafts are combined with metal plates or other types of instruments.

Some types of herniated discs are suitable for treatment by microsurgery or by a technique known as percutaneous discectomy, in which the disc is repaired through the skin without making a surgical incision. For this technique, the surgeon uses an X ray as a guide for inserting a large bore needle into the center of the disc; the central portion of the disc is then removed by using fine instruments that are placed through the needle. You should discuss with your surgeon the various treatment options to determine which is the most appropriate for your specific problems.

To treat spinal stenosis, the surgeon makes an incision that is long enough to allow inspection of all of the vertebrae that have contributed to narrowing of the vertebral canal. After performing a limited laminectomy, the surgeon performs a decompression operation by entering the vertebral canal and removing the material that is pressing on the spinal nerve roots. Occasionally, some form of spinal fusion or other type of stabilization may be indicated.

When a patient has a spinal tumor, the physician may opt to treat the patient with radiation or chemotherapy rather than a surgical operation. If an operation is needed, the surgeon performs a laminectomy, locates the tumor, and removes it from the spine, the spinal cord, and the nerve roots. Some tumors require that the operation be approached from the front of the spine, followed by spinal stabilization. Following the removal of a spinal tumor, the surgeon decides if further radiation therapy and/or chemotherapy should be given.

When a patient has a spinal infection with an abscess in the back part of the spinal canal, the surgeon removes the vertebral arch, locates the abscess, and drains away the pus. If the abscess is toward the front (anterior) in the disc space, the surgeon may make an anterior approach to the vertebral bodies. Appropriate antibiotics will be given to cure the infection.

Recovering from the Operation

Recovering after back surgery varies with the type of operation that was performed. Following ordinary disc removal, most patients are able to get out of bed and move about on the same day after surgery and get discharged on the very next day. Patients who have undergone a spinal fusion or an operation for stenosis take longer to become mobile (upto 12-24 hours), and these patients may remain in the hospital for longer periods of time (48-72 hours) after the operation. In addition, they may be required to wear a brace or cast for a few weeks to months after surgery.

The length of stay for patients with spinal tumors depends on the type of tumor. Patients who have had an operation to drain an abscess of the spine stay in the hospital until the infection has been controlled.

A common problem after major back surgery is difficulty with urination. This problem usually subsides in three to four days. The insertion of a tube (catheter) into the bladder that will drain the urine may be necessary until the patient is able to void normally. After discharge from the hospital, most back surgery patients will need some time to recuperate before returning to their usual activities. The types of activities the patient can safely resume should be outlined by the operating surgeon and should be followed carefully by the patient. The period of recuperation varies, but it may range from weeks to months, and a back brace or physical therapy program may be recommended.

Spine Surgeons:

A fully trained Spine surgeon is a physician who, after medical school, has gone through years of training in an accredited residency program to learn the specialized skills of a Spine Surgery. One good sign of a surgeon's competence is certification by a University of National / International Repute. All such Fellowship Trained surgeons have satisfactorily completed an approved residency training program and have passed a rigorous specialty examination.

Surgeons who become Fellows of the University have passed a comprehensive evaluation of their education, training, and professional qualifications, and their credentials have been found to be consistent with the standards established and demanded by the University.

Types of Low Back Pain

Pain in the lower back is very common. Fortunately 70 percent of people who have low back pain get better within two weeks. And more than 90 percent get better within four to six weeks. Inflammation (swelling) of the joints, muscles or discs in the back often causes low back pain. Physical activities especially repetitive lifting, bending and twisting can make low back pain worse. Poor posture also can worsen low back pain. Rarely do serious problems, such as infection or other medical conditions, cause low back pain.

Types of Low Back Pain

Acute Low Back Pain
Low back pain that lasts for six weeks or less is called acute low back pain, lumbar muscle strain or backache. Although quite painful, it usually improves after a few days of simple care.

Acute Sciatica
Acute sciatica is low back pain that lasts for six weeks or less and extends below the waist. It also is called radiculopathy or radiating leg pain. Feeling better usually takes longer than with acute low back pain. Nerve irritation in the lower back often causes sciatica pain.

Chronic Low Back Pain & Sciatica
Back pain and sciatica that lasts longer than six weeks with no significant improvement is considered chronic. Specialized treatment may be needed. Your doctor may refer you to an expert in medical problems that causes chronic back pain. Usually, these are doctors in rehabilitation or occupational medicine, neurology or neurosurgery, orthopedics, Spine Surgery and rheumatology.

In some situations, your doctor may want to do tests to rule out any uncommon causes for your back pain. Keep your doctor up-to-date on how you are doing. Schedule a follow-up visit one to three weeks after your initial exam, if recommended immediately report any of the following symptoms or conditions:

  • Unexplained weight loss
  • Constant night pain
  • Fever
  • Urinary difficulties, such as incontinence and retention
  • Leg weakness

Diagnosing Low Back Pain

X-rays usually are not necessary early in treatment. X-rays may be needed for trauma (for example, a fall or car accident), patients older than 50 years or those with other medical problems CT or MRI may be used for chronic sciatica pain.

Understanding how back problems are cared for and what to expect if they do not improve is important. The care you receive for your lower back pain is specific to your needs.

Treatment

The following simple recommendations may help control your pain. Talk with your doctor if you are not getting enough pain relief.

Bed Rest
Prolonged bed rest is not necessary for most back problems. Staying in bed for more than two days may increase the pain and stiffness. Moderate activity that does not significantly worsen the pain is more helpful.

Ice and Heat
Ice or cold packs can reduce the pain and swelling of a muscle strain or spasm (tightening of the muscle). Use ice or cold packs for 20 minutes three or four times a day during the first few days. A hot bath or heating pad after 72 hours of the onset of the injury may further reduce pain. Continue to use ice if it helps to reduce the pain more.

Stress Management
Family, work or financial pressures can affect back pain. Learning to effectively manage everyday stress can help your recovery. Talk with your doctor about any concerns.

Medication
Anti-inflammatory medicines, such as ibuprofen (MotrinŽ, AdvilŽ) or aspirin, can help ease the pain and swelling. If these medicines upset your stomach, use acetaminophen (TylenolŽ) instead. Your doctor also may prescribe muscle relaxants to ease muscle spasms. Muscle relaxants, however, often cause drowsiness. Sometimes your physician may order steroid injections that can ease sciatica pain. Steroids are injected into the epidural space of the spine, which surrounds the nerves within the spinal canal. For localized (limited to a small area) back pain, steroid injections into the joints of the spine may be an option as well. Your doctor also may prescribe oral steroids.

Posture, Sleeping and Weight
Good posture keeps the body's weight aligned (straight) and reduces stress on the back muscles. When sitting, use a chair with enough lower back support or place a pillow behind your back. Change positions frequently. When sleeping, lie on your back with a pillow under your knees or on your side with a pillow between your lower legs.
Being overweight increases stress on the lower back. Weight loss is important to prevent future problems. Also, smoking can cause back pain and hamper relief.

Exercise
To help in your recovery and to prevent further back problems, keep yourself in good physical condition and your back, abdominal muscles and legs strong. Walk daily as soon as you can and gradually add other activities such as Yoga, swimming or water exercises.

Returning to Usual Activities
Returning to work or usual daily activity in a few days or less is important to your recovery. Modifying your responsibilities or limiting your hours may be necessary. While you can expect some discomfort, getting back to regular activities helps prevent your back from becoming weak and stiff. Avoid lifting heavy objects and repetitive bending and twisting.

Spinal Therapy
If you experience severe pain or no improvement after two weeks of minimal treatment, or if you are unable to return to work or your daily activities, your doctor may recommend spinal therapy. Spinal therapists include physical therapists or osteopathic physicians. They work to help restore your normal strength and ability to move and do activities. They provide special exercises, gentle manual techniques, pain-relieving tools (ultrasound, heat, cold) and health education.

Surgery
Surgery rarely is needed for back pain or sciatica. Only five to 10 percent of patients with sciatica need surgery. Conservative (non-surgical) treatments and exercise often are as effective in relieving and preventing pain from returning. Surgery usually is only considered after months of conservative treatment have failed to ease your pain.

How To Keep Your Back And Neck Safe

What is spinal cord injury?

Our spinal cord is a delicate structure extending from the base of our middle of the brain, running down all the way down the neck and the mid back to the waist. The spinal cord, filled with nerves, helps in carrying impulses or messages back and forth from all parts of the body to the brain.

Spinal Cord Injury can be very devastating. A spinal cord injury may occur when a person suffers a trauma to the neck or back in which case, some nerves can no longer send messages to the brain. Bruising or pressure on the spinal cord following an injury may affect a person's ability to use their arms, legs and other parts of the body. The situation can causes difficulty in breathing and also affects sense of feeling or touch. The types of disabilities, however, vary depending on the severity and location of the injury on the spinal cord. Unlike peripheral nerves, if the spinal cord is injured, it cannot regenerate. In other words, the damaged nerves in the spinal cord cannot fix themselves and reconnect. By virtue of this, most spinal cord injuries lead to permanent paralysis and disabilities.

Did you know?

In India, the road traffic accidents (44%) and fall from a height (38%) are the two most common causes of spinal injuries. Spinal injuries occur most commonly in 20-40 years age groups and are more common in males. Unfortunately there is no cure for Spinal Cord Injury. Prevention is the Best Option. Taking proper safety precautionary measures can help in preventing many such injuries and incidents.

Stay Safe

It is essential to realise that spinal cord injury may happen to anyone anytime. Taking some proactive measures may help you avoid hurting your back and suffer from spinal cord injury.

Stay Safe with Seatbelts

Make wearing a seatbelt while travelling in cars a 'must follow' rule for your family and you. Reports of automobile accidents in India keeps on coming in the news and involves rash driving as the main cause. Accidents of such kind can be avoided if you wear your seatbelt while traveling/driving at all times.

Avoid Head Injuries with Helmet

Like a seatbelt, wearing a helmet while riding a bike, scooter or even a bicycle is important and can help in avoiding injuries to the head and neck due to accidents. Make sure that the accompanying member on the back seat is also wearing a helmet.

Swim Safely

When swimming, never dive into an unfamiliar body of water or swimming pool. Always practice "feet first, first time" to learn the depth of the water.

Watch your Step

Many spinal cord injuries may occur due to simple falls while walking or running. That is why, it is important to watch your step and look for slippery or wet floor, uneven roads or potholes filled with muddy water during the monsoons. Even while using and climbing up a ladder or a step stool, make sure not to over step and maintain a balance. Being careful in your daily activities can make a big difference in helping you avoid serious injuries to your back.

Do not jump from higher than 10-12 feet. Even if you land on your feet, it can cause your back to break and spinal injury by transmission of forces.

Beware!

If you are present when someone has a spinal cord injury following a motor vehicle or sports accident, immobilize the part of the spine that is hurt. Do not try to re-align it by yourself. Just keep the injured person fixed avoiding any untoward movement.

Treatment of Spinal cord injury

It involves 3 steps

  • Minimizing further injury to spinal cord
  • Rehabilitation
  • Deal with long term complications
