Most people will at some time experience an episode of serious low back pain, but most cases resolve with minimal intervention
The main value of a history and physical examination is to determine which patients should be referred for imaging and interventions
Early magnetic resonance imaging has not been shown to improve outcomes for low back pain
The risk factors for progression to chronic back pain are predominantly psychosocial and occupational.
Most treatments for chronic low back pain have a small effect and/or afford transient benefits
Back pain is the leading cause of occupational disability in the world and the most common cause of missed workdays. As the population ages and our lives become more sedentary, this situation is unlikely to change. We aim here to provide an evidence based overview of low back pain aimed at primary care physicians.
Scope of problem
The most frequently quoted epidemiological studies cite lifetime adult prevalence rates varying from 50% to 80%, and point prevalence rates from 15% to 30%.1 Yet even these statistics may underestimate the problem. A recent prospective study of 154 reserve soldiers with no prior history of back pain found that 64% of this low risk group developed at least moderate back pain over an 18 month period when queried monthly.w1 This suggests that reported prevalence rates may be a function of the type and frequency of surveillance.
What features on history and examination can help identify the cause?
Box 1 lists the causes of low back pain. The origin of pain can be broadly classified as mechanical, neuropathic, or secondary to another cause. Mechanical back pain implies that the source of pain is in the spine or its supporting structures. Neuropathic back pain denotes the presence of symptoms that stem from irritation of a nerve root(s).
Box 1 Common causes of low back pain*
Unknown cause—usually attributed to muscle strain or ligamentous injury (65%-70%)
Degenerative disc or joint …
