Lumbalgia is the medical term for the more common lay discription of low back pain or lower back pain. It is used to describe a symptom related to the lower section of the human spine. Persistant and recurring low back pain affects 60 - 80% of people at some stage in their life and is the most common reason for lost work.[1]

Low back pain varies in intensity, frequency, duration, and quality depending on the cause and stage of injury or illness as well as the time of day and activity level. It is considered either acute (of recent origin) or chronic (longer term) in nature, though these give little insight as to a particular cause of the pain. The degree of pain ranges from a mild annoyance that comes and goes to constant and totally disabling.

Etymology

"Lumbalgia" derives from the Latin "Lumbaris" referring to the lower or loin region of the body and "algia" is from the Greek "algos" for pain.

Background

The low back performs two major functions; to act as a weight bearing column that supports upright posture and to act as a conduit that protects the spinal cord and the tender nervous system that tranmits through it. As a supporting structure, it carries the weight of the upper torso including the head, arms, thorax, and abdominal contents. Impact forces from actions such as walking or jumping multiply these forces exponentially.

The structures of the adult low back consist of the lower five verterbae along with the ligaments, discs and muscles that support it. Together they are identified as the lumbar region of the spine and are frequently labeled L1 to L5. The range of movement that occurs at the lumbar level combined with flexion of the hips is responsible for the majority of the total range of motion necessary for bending. The lumbar spine sits atop the sacrum which is a wedge shaped bone that rests into a space formed by the left and right innominate bones. The innominates are divided into the ilium, ischium and pubis and, with its attached musculature, make up the pelvic girdle that acts to connect the leg to the torso. Together with the sacrum, the left and right innominates wrap around to the lower abdominal region, creating a "bowl" that supports the organs contained within the abdomen. The joint between the sacrum and each innominate (sacroiliac joint) allows for slight motion with walking and bending. The sacrum and innominates together with their supporting ligaments and muscles are referred to as the pelvis. The resulting circle-like formation is commonly called the pelvic ring. For the lay person, the combination of the lumbar and pelvic regions are effectively called the low back. Low back pain can be generated from injury to any or all of the joints, muscles, ligaments or nerves that make up the region as well as organs in the pelvic bowl that get their nerve supply from the low back.

For the purposes of understanding the causes of low back pain, it is important to note that all pain is a perception of the person that is experiencing it. These perceptions are the result of an intricate relationship between the nerve endings that monitor the condition of the tissues and send that information to the higher centers of the brain where the conscious perception actually occurs. The vast majority of the nerve endings are in the ligaments, muscle and outer layer of the disc tissues that support the boney structures. While bones have a thin 'skin' or periosteum that has a plentiful nerve supply, the bones themselves do not. This is also the case of the inner portions of the disc.

Causes

The majority of acute causes of low back pain are grouped as mechanical type injuries to the ligaments, muscles and joints that are responsible for the function of the vertebral column. The injury may be the result of one traumatic event or multiple, repetitive type traumas. If the cause of these mechanical conditions persist, the pain may develop into a chronic low back pain with a change in symptom quality and frequency depending on the type of structures that become affected, such as discs and nerves. These include diagnoses such as osteoarthritis, degeneration of the discs or a spinal disc herniation.

Some cases of low back pain are related to systemic conditions that affect other regions of the body such as rheumatoid arthritis or cardivascular disease, while a small percentage are caused by tumors (including cancer). There are psychological or emotional components of all disease and low back pain is no exception.

Possible causes of low back pain:

Diagnosis

Often, getting a diagnosis of the underlying cause of low back pain and/or related symptoms, such as sciatica, 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 magnetic resonance imaging or x-ray.[2] However, a randomized controlled trial of routinely obtaining an MRI scan in back pain showed no benefit but increased costs.[3]

History and physical examination

The goal of the history and physical examination is to place the patient into one of three categories:[4]

Nonspecific low back pain

"nonspecific low back pain"

Possible radiculopathy or spinal stenosis

"Back pain potentially associated with radiculopathy or spinal stenosis (suggested by the presence of sciatica or pseudoclaudication)"[4] These patients may have a positive straight leg raise sign.

Other specific spinal causes

"Back pain potentially associated with another specific spinal cause. The latter category includes the small proportion of patients with serious or progressive neurologic deficits or underlying conditions requiring prompt evaluation (such as tumor, infection, or the cauda equina syndrome), as well as patients with other conditions that may respond to specific treatments (such as ankylosing spondylitis or vertebral compression fracture)."

Non-spinal causes

Sometimes back pain may be pain radiating from another location.


MRI scan and CT scan

"MRI or CT is recommended in patients who have severe or progressive neurologic deficits or are suspected of having a serious underlying condition (such as vertebral infection, the cauda equina syndrome, or cancer with impending spinal cord compression)". Obtaining MRI scan for lesser reasons may lead to increased costs of unnecessary tests, unnecessary follow-up, and possibly even unnecessary treatment of incidental findings [3]

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.

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. When evaluating treatment options, concepts utilized in Evidence based medicine can help determine which treatments that might be appropriate. Systematic reviews of medical evidence by the Cochrane Collaboration and systematic review-based clinical practice guidelines American College of Physicians[4][5][6][7] are available to guide treatment choices. Listed alphabetically, some of those evaluations include:

Home or Outpatient

Nondrug treatments

  • Acupuncture has a similar benefit for chronic back pain as other therapies in the short term and shows promise for 1 to 2 year follow up.[8][9]
  • Heat therapy is useful for back spasms or other conditions in acute or subacute situations.[10]
  • Exercises, whether performed individually or under supervision of a professional, are generally believed to be an essential component of most back treatment programs. However, exercises are effective for chronic back pain, but not for acute pain. Back-mobilizing exercises in acute settings are less effective than continuation of ordinary activities as tolerated, though there is some evidence that when part of a 'back school', exercises can improve back pain.[11][12][13][4]
  • Massage has shown some benefit for patients with subacute and chronic non-specific low-back pain, especially when combined with exercises and education.[14].
  • Manipulation has a benefit similar to other therapies for both acute and chronic low back pain. Though considered safe, it is not without risk.[15][16][5] The patients most likely to benefit have at least four of the following criteria: 1) symptoms for less than 16 days, no symptoms below the knee, low fear of engaging in work or physical activity[17], at least 1 hypomobile lumbar joint, and at least 1 hip with more than 35° of internal rotation.[18]
  • Respondent-cognitive therapy and progressive relaxation therapy can reduce chronic pain as well as exercise therapy.[19][5].
  • Work place and home habit modifications help most people through assessing any ergonomic or postural factors that may contribute to their back pain, such as improper lifting technique, poor posture, or poor support from their bed or office chair, etc.[13].
  • Yoga either Viniyoga[20], Iyengar[21], or Hatha[22] might help with the best evidence, albeit only fair-quality evidence, supporting Viniyoga.[5]

Medications

Combination therapies

Difficulties in treating chronic back pain have to lead to investigations of combined modalities. One trial found some benefit from combining exercise with cognitive behavioral therapy. [29]

Surgery

There are a number of different types of spine surgery to treat a variety of back conditions. Surgery should be considered if a patient has a significant neurological deficit, or if they fail non-surgical therapy. There is particular concern if back pain is associated with loss of bowel or bladder function and may indicate Cauda equina syndrome or Conus medularis syndrome. Urgent surgical considerations are necessary for these conditions.

Some of the more common forms of surgery are:[30]

  • Kyphoplasty and Vertebroplasty, minimally invasive procedures designed to treat pain from osteoporotic compression fractures and sometimes other forms of fracture, such as a fracture caused by certain types of cancer.
  • Laminectomy, removes a portion of the bone to relieve pressure on the spinal nerve from behind.

Treatments with uncertain or doubtful benefit

  • Cold compression therapy is advocated for a strained back or chronic back pain and is postulated to reduce pain and inflammation, especially after strenuous exercise such as golf, gardening, or lifting. However, a meta-analysis of randomized controlled trials by the Cochrane Collaboration concluded "The evidence for the application of cold treatment to low-back pain is even more limited, with only three poor quality studies located. No conclusions can be drawn about the use of cold for low-back pain" [10]
  • Bed rest is rarely recommended as it can exacerbate symptoms [33], and when necessary is usually limited to one or two days.

Prevention

In some setting, lumbar supports may be able to prevent back pain.[34]
