| '''Low back pain''' is a common musculoskeletal disorder which affects the lumbar segment of the spine. It can be either [[Acute (medical)|acute]], subacute or [[Chronic (medicine)|chronic]] in its clinical presentation. Typically, the symptoms of low back pain do show significant improvement within two to three months from its onset. In a significant number of individuals, low back pain tends to be recurrent in nature with a waxing and waning quality to it. In a small proportion of sufferers this condition can become chronic. Population studies show that back pain affects most adults at some stage in their life and accounts for more sick leave and disability than any other single medical condition.

| | |
| An acute lower back injury may be caused by a traumatic event, like a car accident or a fall. It occurs suddenly and its victims will usually be able to pinpoint exactly when it happened. In acute cases, the structures damaged will more than likely be soft tissue like [[muscle]]s, [[ligament]]s and [[tendon]]s. With a serious accident or due to osteoporosis or other causes of weakened vertebral bones, vertebral fractures in the lumbar spine may also occur. At the lowest end of the spine, some patients may have tailbone pain (also called [[coccyx]] pain or [[coccydynia]]). Others may have pain from their sacroiliac joint at the bottom of the lumbar spine, called sacroiliac joint dysfunction.
| |
| | |
| Chronic lower back pain usually has a more insidious onset, occurring over a long period of time. Physical causes may include [[osteoarthritis]], [[rheumatoid arthritis]], [[degenerative disc disease|degeneration of the discs]] between the [[vertebrae]], or a [[spinal disc herniation]], a vertebral fracture (such as from [[osteoporosis]]), or rarely, a tumor (including [[cancer]]) or infection. The cause may also be psychological or emotional or due to other non-anatomical factors.

| Diagnosing the underlying cause of low back pain is usually done by a [[medical doctor]], osteopathic physican, physiotherapist (physical therapist) or by a chiropractor. Often, getting a diagnosis of the underlying cause of low back pain and/or related symptoms is quite complex. A complete diagnosis is usually made through a combination of a patient's medical history, physical examination, and, when necessary, diagnostic testing, such as an MRI scan or [[x-ray]]. There are a number of health care professionals who may specialize in diagnosing and treating low back pain, including chiropractors, osteopathic physicians, physical therapists (physiotherapists), physical therapy physicians, anesthesiologists/pain medicine physicians, and orthopedic surgeons or neurosurgeons.

| ==Treatments==
| |
| The course of treatment for low back pain will usually be dictated by the clinical [[diagnosis]] of the underlying cause of the [[Pain and nociception|pain]].
| |
| | |
| ===Conservative treatment===
| |
| For the vast majority of patients, low back pain can be treated with non-surgical care. For those with acute, short-term back pain, certain home remedies<ref>{{cite web |url=http://www.back.com/articles-back_pain_relief.html |title=Acute back pain. Causes and treatment options. |accessdate=2007-09-26 |format= |work=}}</ref> may be effective.

| ====Other treatments==== | | ==Case Studies== |
| Additional treatments have been more recently reviewed by the [[Cochrane Collaboration]]:
| | [[Low back pain case study one|Case #1]] |
| * [[Massage]] therapy may benefit some patients (PMID 12076429)
| | ==Related Chapters== |
| * Ice and/or heat application (or moist heat) has uncertain benefit (PMID 16437495).
| | * [[Back pain|Back Pain]] |
| | | * [[Upper back pain|Upper Back Pain]] |
| Individual [[randomized controlled trials]], thus interpretation may be subject to publication bias, also confounded by absence of double blinding have shown benefit for:
| | * [[Chronic pain|Chronic Pain]] |
| * Viniyoga (PMID 16365466), Iyengar (PMID 15836974), and Hatha yoga (PMID 15055095 - small trial).
| | * [[Spinal disc herniation|Spinal Disc Herniation]] |
| * Correcting leg length difference may help (PMID 16271551). To correct leg length difference, insert a hard rubber or cork heel pad into the shoe of the short leg if the difference between the two legs is 3/8ths inch or less. If more, have a shoe repairman build up the sole and heel. Taper the toe to avoid tripping. If more than 3/4 inch, start with 1/2 of what you need so that your body can adjust.
| | * [[Degenerative disc disease|Degenerative Disc Disease]] |
| * [[Muscle Energy Technique]] (MET) may help (PMID 14524509 - small study)
| | * [[Coccydynia|Coccydynia (Coccyx Pain, Tailbone Pain)]] |
| | |
| Other treatments that were not reviewed are
| |
| * Education and attitude adjustment (TMS)
| |
| * Increasing internal hip rotation
| |
| * Increase internal hip rotation with stretching or connective tissue massage
| |
| | |
| Because of variations in clinical study methodology, a review of clinical studies in any one area is not necessarily conclusive.
| |
| | |
| For any one condition, it may be necessary to try a variety of treatments in order to find the best one (or combination) to best manage the pain. In almost all cases, [[physical therapy]] and/or a regular [[exercise]] program that includes stretching, strengthening and low impact cardio conditioning will be part of the treatment and rehabilitation program.
| |
| | |
| The role of [[narcotic]]s for ''chronic'' low back pain is uncertain.<ref name="pmid17636781">{{cite journal |author=Deshpande A, Furlan A, Mailis-Gagnon A, Atlas S, Turk D |title=Opioids for chronic low-back pain |journal=Cochrane database of systematic reviews (Online) |volume= |issue=3 |pages=CD004959 |year=2007 |pmid=17636781 |doi=10.1002/14651858.CD004959.pub3}}</ref>
| |
| | |
| ===Surgery===
| |
| | |
| Lumbar surgery is indicated when conservative treatment is not effective in reducing pain or when the patient develops progressive and functionally limiting neurologic symptoms such as leg weakness, bladder or bowel incontinence, which can be seen with severe lumbar disc herniation, spinal abscess or cauda equina syndrome. Other possible indications for surgery include:
| |
| | |
| * Severe [[Degenerative disc disease]]
| |
| * [[Spinal stenosis]]
| |
| * [[Spondylolisthesis]]
| |
| * [[Scoliosis]]
| |
| * [[Compression fracture]]
| |
| * Spinal instability
| |
| * Spinal [[trauma]]
| |
| * Spinal [[malignancy]] ([[cancer]])
| |
| * Spinal [[hematoma]]
| |
| | |
| The most common types of low back surgery include microdiscectomy, discectomy, laminectomy, foraminotomy, or spinal fusion. Another less invasive surgical technique consists of an implantation of a spinal cord stimulator and typically is used for symptoms of chronic radiculopathy ([[sciatica]]). Lumbar artificial disc replacement is a newer surgical technique for treatment of [[degenerative disc disease]], as are a variety of surgical procedures aimed at preserving motion in the spine.
