Overview
Back pain is pain felt in the back that may originate from the muscles, nerves, bones, joints or other structures in the spine. The pain may be have a sudden onset or it can be a chronic pain, it can be felt constantly or intermittently, stay in one place or refer or radiate to other areas. It may be a dull ache, or a sharp or piercing or burning sensation. The pain may be felt in the neck (and might radiate into the arm and hand), in the upper back, or in the low back, (and might radiate into the leg or foot), and may include symptoms other than pain, such as weakness, numbness or tingling.
Back pain is one of humanity's most frequent complaints. In the U.S., acute low back pain (also called lumbago) is the fifth most common reason for all physician visits. About nine out of ten adults experience back pain at some point in their life, and five out of ten working adults have back pain every year.[1]
The spine is a complex interconnecting network of nerves, joints, muscles, tendons and ligaments, and all are capable of producing pain. Large nerves that originate in the spine and go to the legs and arms can make pain radiate to the extremities.
Classification
On the basis of origin, back pain can be broadly classified into three categories: axial, referred, and radicular. Back pain can also be classified on the basis of its underlying etiology into mechanical and non-mechanical.
Causes
The causes of back pain can be stratified according to age. Common causes of back pain in adults under the age of 50 years include, ligament strain, nerve root irritation, spinal disc herniation, degenerative disc disease and isthmic spondylolisthesis. Common causes in adults over the age of 50 years include osteoarthritis (degenerative joint disease), spinal stenosis, trauma, cancer, infection, fractures, and inflammatory disease. Non-anatomical factors can also lead to back pain, such as stress, repressed anger, or depression. Even if an anatomical cause for the pain is present, a coexistent depression should be treated concurrently.
Risk Factors
Risfactors for back pain include poor posture, obesity, pregnancy, cancer, weight lifting, psychological stress, smoking, sedentary lifestyle, lack of exercise, autoimmune disease.
Screening
There is insufficient evidence to recommend routine screening for back pain.
Natural history, Complications and Prognosis
Natural history, complications and prognosis largely depend on the underlying cause of back pain. Back pain progresses and presents varialbly depending on the pathology. Back pain of any origin can lead to deformity, disability, depression, weight gain, social isolation, decreased quality of life, and sleep disturbances. Prognosis varies according to the underlying etiology, most patients will recover with within weeks. Recurrent and chronic cases are more resistant to treatment.
Diagnosis
X Ray
X-ray imaging includes conventional and enhanced methods that can help diagnose the cause and site of back pain. A conventional x-ray, often the first imaging technique used, looks for broken bones or an injured vertebra. A technician passes a concentrated beam of low-dose ionized radiation through the back and takes pictures that, within minutes, clearly show the bony structure and any vertebral misalignment or fractures. Tissue masses such as injured muscles and ligaments or painful conditions such as a bulging disc are not visible on conventional x-rays. This fast, noninvasive, painless procedure is usually performed in a doctor’s office or at a clinic.
Myelograms also enhance the diagnostic imaging of an x-ray. In this procedure, the contrast dye is injected into the spinal canal, allowing spinal cord and nerve compression caused by herniated discs or fractures to be seen on an x-ray.
CT
Computerized tomography (CT) is a quick and painless process used when disc rupture, spinal stenosis, or damage to vertebrae is suspected as a cause of low back pain. X-rays are passed through the body at various angles and are detected by a computerized scanner to produce two-dimensional slices (1 mm each) of internal structures of the back. This diagnostic exam is generally conducted at an imaging center or hospital.
MRI
Magnetic resonance imaging (MRI) is used to evaluate the lumbar region for bone degeneration or injury or disease in tissues and nerves, muscles, ligaments, and blood vessels. MRI scanning equipment creates a magnetic field around the body strong enough to temporarily realign water molecules in the tissues. Radio waves are then passed through the body to detect the “relaxation” of the molecules back to a random alignment and trigger a resonance signal at different angles within the body. A computer processes this resonance into either a three-dimensional picture or a two-dimensional “slice” of the tissue being scanned, and differentiates between bone, soft tissues and fluid-filled spaces by their water content and structural properties. This noninvasive procedure is often used to identify a condition requiring prompt surgical treatment.
Ultrasound
Diagnostic musculoskeletal ultrasound imaging, also called ultrasound scanning or sonography, uses high-frequency sound waves to obtain images inside the body. The sound wave echoes are recorded and displayed as a real-time visual image. Ultrasound imaging can show tears in ligaments, muscles, tendons, and other soft tissue masses in the back.
Treatment
Conservative Treatment
The management goals when treating back pain are to achieve maximal reduction in pain intensity as rapidly as possible; to restore the individual's ability to function in everyday activities; to help the patient cope with residual pain; to assess for side-effects of therapy; and to facilitate the patient's passage through the legal and socioeconomic impediments to recovery. For many, the goal is to keep the pain to a manageable level to progress with rehabilitation, which then can lead to long term pain relief. Also, for most people the goal is to use non-surgical therapies to manage the pain and avoid major surgery, but for others surgery may be the quickest way to feel better. Not all treatments work for all conditions or for all individuals with the same condition, and many find that they need to try several treatment options to determine what works best for them. The present stage of the condition (acute or chronic) is also a determining factor in the choice of treatment. Only a minority of back pain patients (most estimates are 1% - 10%) require surgery.
