Backache

Low back pain and neck pain are one of the most common reasons to seek medical attention. Pain is usually caused by problems with the musculoskeletal system - most pronounced with problems with the spine, including the bones of the spine (vertebrae), discs, and the muscles and ligaments that support them. Sometimes back pain is caused by a condition that doesn't affect the musculoskeletal system.

Low back pain is more common in older age groups and affects more than half of people over 60. It leads to significant costs in terms of healthcare payments, disability benefits and lost working hours.

The spine (spinal column) is made up of vertebrae. There are shock absorbing discs between the vertebrae. The discs have a hard outer layer of fibrocartilage tissue and a soft, jelly-like inner substance called the nucleus. Each vertebra has two joints behind the discs. These joints are called joint facets. The articular surfaces of one vertebral body lie on the articular surfaces of the other under it, forming a joint. The joints, and with them the entire spine, are stabilized by ligaments and muscles, namely:

• Two iliopsoas muscles that run on either side of the spine
• Two erector back muscles that run the entire length of the spine behind it
• Many short paravertebral muscles located between the vertebrae

The spinal cord is located in the spinal canal. Along the entire length of the spinal cord, through the holes between the vertebrae on both sides, the spinal nerves come out, the function of which is to unite all the nerves in the body. The part of the spinal nerve near the spinal cord is called the root. Due to the peculiarities of the location of the roots of the spinal nerves, they can be compressed (compressed) with injuries of the spine, which lead to pain.

The lower spine (lumbar spine) at the top connects to the upper spine (thoracic spine) and below the pelvis through the sacrum. The lumbar spine is flexible enough to bend, twist and bend, and provides strength by standing, walking, and lifting. Therefore, the lower back is involved in almost all types of daily activities. Low back pain can interfere with various activities and degrade quality of life.

Types of back pain

Common types of low back pain include localized, radiating, and repercussion pain.

Local painappears in a certain area of the lower back. It is the most common type of back pain. The cause is usually a disc injury, joint arthritis, and, less commonly, a muscle strain. The pain can be continuous and aching, or at some point it can be replaced by acute intermittent pain. Sudden pain can appear when the cause is trauma. Local pain may increase or decrease with a change in position. Touching the lower back can be painful. Muscle spasms are possible.

Radiant painIt is low back pain that spreads to the leg. The pain can be dull or sharp and intense. Typically, it affects only the side or back of the leg and can extend to the foot or to the knee only. Radiant pain is usually a manifestation of compression of the spinal nerve root in disorders such as a herniated disc, sciatica, osteoarthritis, or spinal stenosis. Coughing, sneezing, straining, or bending over with straight legs can be painful. When a spinal nerve root is compressed, the pain may be accompanied by weakness of the leg muscles, a tingling sensation, or even loss of sensation. In rare cases, loss of control of urination (urinary incontinence) or loss of control of bowel movements (fecal incontinence) occurs.

Reflex painfelt in a place other than the true cause of the pain. For example, some people with a heart attack experience pain in their left arm. Pain reflected from internal organs in the lower back is predominantly of a deep, aching nature and its exact location is difficult to determine. As a rule, with movement, the pain does not increase, in contrast to the pain accompanying disorders of the musculoskeletal system.

The reasons

In most cases, back pain is a consequence of diseases of the spine and surrounding joints, muscles, ligaments and roots of the spinal nerves, as well as the intervertebral discs. It is often not possible to identify a single specific cause. Any painful disease of the spine can lead to reflex contraction (spasm) of the muscles around the spine. The spasm can increase the pain. Stress can make low back pain worse, but the mechanism is unclear.

Sometimes, back pain is caused by a disorder that does not affect the spine, such as cancer, gynecological conditions (such as PMS), kidney disease (such as kidney stones), urinary tract disease (such as kidney infections, etc. and prostate) and digestive tract (for example, diverticulitis), as well as diseases of the large arteries located near the spine.

Common causes

Common causes of back pain include the following:

• Osteoarthritis
• Compression fractures of the spine
• A ruptured or herniated disc
• Spinal stenosis in the lumbar spine
• spondylolisthesis
• Damage to muscles and ligaments
• fibromyalgia

Damageit can occur during normal activities (for example, lifting heavy objects, exercise, unexpected movement) or as a result of injury, such as a fall or car accident. Typically, imaging studies show no specific lesions, but doctors suspect certain muscles and / or ligaments are involved.

Osteoarthritis(degenerative arthritis) causes wear of the cartilage between the joint surfaces and the formation of bone spines (osteophytes). This disease is partly the result of years of wear and tear on the fabrics. With severe degeneration and loss of disc height, osteophytes in the foramen can compress the spinal nerve roots. All of these changes can lead to lower back pain and stiffness.

Compression fractures of the spine (due to compression)(vertebral fractures) often occur when bone density decreases due to osteoporosis, which usually develops with age. However, fractures due to osteoporosis tend to occur in the upper and middle of the back and are accompanied by pain in these regions rather than in the lower spine.

A ruptured or herniated disccan cause back pain. The disc is represented by a dense outer layer and a soft, gelatinous central part. If the disc is subjected to constant stress from the vertebrae above and below (for example, when bending forward, especially when lifting heavy objects), its outer layer can rupture (tear), causing pain.

Spinal stenosis in the lumbar spine- Narrowing of the spinal canal (which runs through the center of the spine and contains the spinal cord and bundle of nerves that extend downward from the lower part of the spinal cord) in the lumbar region. It is a common cause of low back pain in older people. Spinal stenosis also develops in middle age in people whose spinal canal is narrow from birth. Spinal stenosis is caused by disorders such as osteoarthritis, spondylolisthesis, ankylosing spondylitis and Paget's disease.

Spinal stenosis can cause sciatica and back pain.

spondylolisthesis- partial displacement of the vertebra in the lower part of the spine. One type usually occurs during adolescence or adolescence (often in athletes) and is caused by an injury that fractures part of the vertebrae. If both sides of the vertebra are affected, the vertebra can slide forward onto the vertebra below. Spondylolisthesis can also occur in the elderly, but mainly due to a degenerative disease. With the development of spondylolisthesis in adulthood, the risk of spinal stenosis in the lumbar region increases.

fibromyalgiaIt is a common cause of pain affecting many parts of the body, including the lower back. This condition causes chronic widespread pain in the muscles and other soft tissues outside the lower back. Fibromyalgia is also characterized by sleep disturbances and fatigue.

Surveys

Tests are usually not prescribed because most back pain is due to osteoarthritis, sprains, or other minor musculoskeletal disorders and resolves within 6 weeks. Imaging tests are often needed if:

• another reason is suspected;
• there are warning signs;
• back pain persists.

Evaluation can also be ordered if there is no response to initial treatment or if symptoms worsen or change.

X-rays of the lower back can only provide a picture of the bones. These images can detect degenerative changes due to osteoarthritis, spinal compression fractures, spondylolisthesis and ankylosing spondylitis. However, magnetic resonance imaging (MRI) or computed tomography (CT) can provide a clear image of the bones and, as is typical with MRI, visualize soft tissue (including discs and some nerves). An MRI or CT scan is usually needed when doctors determine the presence of disorders that lead to some changes in the structure of the bones, as well as soft tissue diseases.

If spinal cord compression is suspected, MRI is done as soon as possible. In rare cases, when MRI results are ambiguous, CT myelography becomes necessary. Rarely, if a malignant tumor or infection is suspected, a tissue sample (biopsy) must be taken for analysis. In some cases, electromyography and tests are done to study nerve conduction to confirm the presence, location, and, in some cases, the duration and severity of the spinal nerve root compression.

Prophylaxis

People can reduce their risk of developing low back pain by taking the following steps:

• phisical exercises;
• exercises to strengthen and stretch muscles;
• maintaining a normal body weight;
• maintaining correct posture;
• compliance with the recommendations for safe weight lifting.

The most effective way to prevent low back pain is through regular exercise. Aerobic exercises and special exercises for developing muscle strength and stretching are recommended.

Aerobic exercise, such as swimming and walking, improves overall fitness and strengthens muscles.

Special exercises for the development of muscle strength and the elongation of the muscles of the abdominal wall, buttocks and back (deep trunk muscles), allow to stabilize the spine and reduce the elongation of the discs that absorb the spine and ligaments that you keep them.

Strength-building exercises include pelvic tilts and abdominal crunches. Stretching exercises include stretching by bending the knees to the chest. In some people, stretching exercises can lead to increased back pain, so care should be taken. The basic rule is that any exercise that causes or worsens back pain must be stopped. Exercises should be repeated until mild (but not extreme) muscle fatigue is felt. Breathing is essential during exercise. People with back pain should consult a doctor before exercising.

Pelvic tilts Take a supine position with your knees bent, heels on the floor, load on your heels. Press your back to the floor, contract your glutes (lift them about half an inch off the floor), and contract your abdominal muscles. Hold this position for a count of 10. Repeat 20 times.
Lying down crunches Lie down on your sleep with your knees bent and feet flat on the floor. Fold your arms across your chest. Contract your abdominal muscles, slowly lift your shoulders about 10 inches off the floor, keeping your head straight (chin shouldn't touch your chest). Relax your abdominal muscles, slowly lower your shoulders. Do 3 sets of 10 reps.
Stretch with your knees to your chest Get into a supine position, straighten up. Place both palms under one knee and press it to your chest. Hold this position for a count of 10. Slowly lower your leg and repeat the exercise on the other leg. Do the exercise 10 times.

Exercise also makes it easier to maintain your desired body weight. Exercise also helps maintain bone density. Therefore, exercise can reduce the risk of developing two conditions that can cause low back pain: obesity and osteoporosis.

Correct standing and sitting posture reduces stress on the back. Slouching should be avoided. The seats of the chairs should be adjusted in height so that the feet are flat on the floor, the knees are slightly bent and the lower back is snug against the back of the chair. If the chair does not provide support for the lower back, a cushion can be placed under it. In a sitting position, it is recommended to place your feet on the floor, not to cross your legs. Sick people should not stand or sit for long periods. If you have to stand or sit for a long time, frequent changes of position can reduce the strain on your back.

Treatment

If it is possible to determine a specific cause, the disease is treated. For example, antibiotics are used to treat a prostate infection. However, there is no cure for sprain pain in the musculoskeletal system or for pain caused by other conditions. However, the situation can be improved through general measures. Typically, such measures are also used when squeezing the spinal nerve root.

General measures for back pain

Possible measures include:

• Make changes to activities
• Taking pain relievers
• Apply heat or cold to the painful area
• Light exercise, if tolerated

For more recent back pain, treatment begins by eliminating activities that strain the back and cause pain, such as lifting weights and bending over. Bed rest does not accelerate pain relief, and most professionals recommend doing light work. Bed rest, needed to relieve severe pain, should not last more than 1 or 2 days. Prolonged bed rest weakens core muscles and increases stiffness, causing back pain to worsen and slower recovery. Corsets and traction are ineffective. Traction can slow healing.

Over-the-counter or prescription non-steroidal anti-inflammatory drugs (NSAIDs) can relieve pain and reduce inflammation. Opioid analgesics are sometimes prescribed if NSAIDs do not provide sufficient pain relief, but should only be used for a short time, as long-term use of opioid analgesics can, on the contrary, increase pain sensitivity, cause effects collateral and increase the risk of addiction and addiction.

Muscle relaxants can sometimes relieve muscle spasms, but their effectiveness is questionable. These drugs are not recommended for older patients who are more likely to develop side effects such as sleepiness and disorientation. Doctors try not to prescribe muscle relaxants if the patient does not have visible and palpable muscle spasms. If muscle relaxants are prescribed, they should not be used for more than 72 hours. Doctors sometimes recommend taking them just before bed.

Massage can provide temporary relief from lower back pain. Some studies have shown positive results in acupuncture, others have contradicted these results. Manipulation of the spine by chiropractors or other doctors (such as osteopaths), combined with an exercise program, can also relieve pain. However, manipulation of the spine can increase the risk of further injury and should be avoided in individuals with inflammatory arthritis, neck problems that cause cervical instability, or a herniated disc.

It is recommended that you sleep in a comfortable position on a medium firm mattress. People who sleep on their backs should have a pillow under their knees. Patients sleeping on their side should use a pillow that allows the head to be kept in a neutral position (without bending the neck up or down). Patients should place a second pillow between their knees, with the knees and hips slightly bent, if this relieves lower back pain. Patients can still sleep on their stomachs if they feel comfortable.

Continue or start taking other preventive measures (correct posture, proper weight lifting technique). When carrying out such events, back pain attacks mostly disappear in the period from several days to 2 weeks. Regardless of treatment, 80 to 90% of these attacks resolve within 6 weeks.

Treatment of chronic low back pain

Additional measures are needed to treat chronic low back pain. Aerobic exercise is recommended, and weight loss is recommended if necessary. If analgesics are ineffective, other treatments should be prescribed.

Transcutaneous electroneurostimulation (TENS) is possible. CHENS devices generate a weak alternating current which causes a slight tingling sensation. This current can block the transmission of some pain sensations from the spinal cord to the brain. The current can be applied to the painful area several times a day, the duration of the session varies from 20 minutes to several hours, depending on the severity of the pain.

Sometimes corticosteroids with a local anesthetic are periodically injected into the facet joint of the spine or into the epidural space, between the spine and the outer layer of tissue that covers the spinal cord. Epidural injections may be more effective for sciatica, which is more due to a herniated disc rather than lumbar spinal stenosis. However, they may not have long-term beneficial effects. They usually only last a few days or weeks. Their main purpose is to relieve pain so that you can exercise for long-term pain relief.

Back pain surgery

In cases where a herniated disc leads to persistent or chronic sciatica, weakness, numbness, or fecal and urinary incontinence, it may be necessary to surgically remove the protruding part of the disc (discectomy) and, in some cases, part of the vertebra ( laminectomy).

In severe spinal stenosis, a large portion of the posterior vertebra (lamellae of the vertebral arch) can be removed to expand it (lumbar laminectomy). General anesthesia is usually required. The length of hospital stay is generally 4-5 days. Patients will be able to return to normal activities in 3-4 months. Approximate or complete recovery is observed in approximately two thirds of patients. For the rest of the patients, such surgery can prevent pain and worsening of other symptoms.

If the spine is unstable (which can result from a severe herniated disc, spondylolisthesis, or laminectomy for spinal stenosis), surgery to fuse the vertebrae (called lumbar vertebrae arthrodesis) may be performed. However, fusion limits mobility, can be accompanied by excessive mechanical stress on the rest of the spine and cause problems in the future.

Compression fractures of the spine

Compression fractures of the spine are quite common in women over 50. They can be treated conservatively without surgery, with braces, pain relievers, and possibly calcitonin nasal spray, which will not help bone healing but can reduce pain.

If sufficient pain control cannot be achieved, two surgical options are available:

• Vertebroplasty: injection of cement mortar into a fractured bone.
• Kyphoplasty - inserting a balloon into a fractured bone to create space. The balloon is then filled with concrete.

However, recent studies have shown that, in the long term, the effectiveness of these surgical procedures does not outweigh the effectiveness of nonsurgical treatment options.

Key points

• Low back pain is common. It is usually caused by musculoskeletal disorders of the spine and factors such as fatigue, obesity, and insufficient physical activity.
• Low back pain is rarely severe at a young age, and tests are usually not needed unless symptoms persist for many weeks.
• Patients with warning signs or patients over the age of 55 should seek immediate medical attention.
• Strengthening the muscles of the abdominal wall and back with specific exercises helps prevent the most common types of low back pain.
• For back pain, very often, sufficient treatment is to rule out measures that lead to mechanical effects on the back, take pain relievers and, in some cases, apply a cold or warm compress.
• Prolonged bed rest and stretching can slow recovery.
• In severe cases, such as abnormal sensations and weakness in the legs, surgery may be required.
• Compression fractures of the vertebrae can be treated conservatively (with braces, pain relievers, and nasal sprays) or, in some cases, more aggressively with surgery.
