Work-related back pain is usually due to falls while standing, falls from heights, or direct blunt trauma to the back. Workers claiming compensation for on-the-job back injury often claim injuries involving low back strain, herniated disks, fractured vertebrae, pinched nerves, and spinal cord injury Spinal Trauma Trauma to the spine may cause injuries involving the spinal cord, vertebrae, or both. Occasionally, the spinal nerves are affected. The anatomy of the spinal column is reviewed elsewhere. Spinal... read more . Malingering may be a concern with regard to work-related back injury and back pain.
Specific work activities, including operating motor vehicles, heavy lifting, repetitive lifting (both heavy and light items), overhead work, and whole-body vibration, have a higher risk of work-related back injury. Specific psychosocial issues may contribute to work-related back pain. These issues include job dissatisfaction, tedious or monotonous work, a perceived heavy workload, tasks with a demanding deadline, and a perceived lack of input to decision-making.
Smoking and obesity are linked epidemiologically to nonoccupational back pain; both are common among workers and thus may also increase the risk of work-related back pain.
A past history of work-related back injury and pain is an important predictor of future back injury.
Diagnosis of Work-Related Back Pain
Sometimes imaging tests
The evaluation of work-related back injury is similar to that for any other back problem. Medical history should include a focused occupational history emphasizing the patient's specific job task and exactly what the patient was doing when injured. A thorough review of the patient’s past occupational medical history is essential. A physical examination should include a focused musculoskeletal and neurologic examination Introduction to the Neurologic Examination The purpose of the neurologic examination is to establish whether the patient’s brain, special senses, spinal cord, peripheral nerves, and muscle and skin receptors are functioning normally... read more .
If the injury was caused by direct trauma (eg, a significant direct blow to the back, a fall from a height) or if justified by clinical findings (eg, neurologic deficits, findings suggesting fragility fracture), imaging (plain x-rays, CT, MRI) is indicated; however, for injury without such causes, imaging is not indicated. Plain x-rays have a notoriously low yield when done to assess work-related back injury and pain.
In many industries, preemployment plain x-rays of the back used to be done for workers at risk of back injury. This practice is no longer recommended because it provides little or no clinically helpful information and exposes workers to unnecessary radiation.
Pearls & Pitfalls
Taking detailed notes when obtaining the history and doing the physical examination is critical. In the US, work-related back injuries may become legal issues in workers’ compensation programs, and in these cases, detailed physician notes often guide the outcome. Disability assessment Disability Assessment Occupational and environmental medicine (OEM) focuses on prevention, diagnosis, and treatment of occupation- and environment-related injuries and illnesses. The goal of OEM is to enhance workers'... read more , as in any other case, may also be done but is a separate assessment.

Strategies to prevent further and future injury
Treatment of work-related back injury is similar to that for any other back injury; it depends on the type of injury (eg, fracture; strain, sprain, tendon injury Treatment Sprains are tears in ligaments; strains are tears in muscles. Tears (ruptures) may also occur in tendons. In addition to sprains, strains, and tendon injuries, musculoskeletal injuries include... read more , herniated disk Treatment Herniated nucleus pulposus is prolapse of an intervertebral disk through a tear in the surrounding annulus fibrosus. The tear causes pain due to irritation of sensory nerves in the disk, and... read more , spinal cord injury Treatment A dislocation is complete separation of the 2 bones that form a joint. Subluxation is partial separation. Often, a dislocated joint remains dislocated until reduced (realigned) by a clinician... read more ). For example, for common injuries of sprains and strains, a brief period of rest (eg, 1 to 3 days), followed by early mobilization, yields the best clinical results and the earliest return to work. Pain is usually treated with acetaminophen or nonsteroidal anti-inflammatory drugs (NSAIDs); opioid analgesics are usually avoided except for severe symptoms. (See also Treatment of Back Pain Treatment Neck pain and back pain are among the most common reasons for physician visits. This discussion covers neck pain involving the posterior neck (not pain limited to the anterior neck) and low... read more )
Prevention of Work-Related Back Pain
Risk of work-related back injury can be reduced, eliminated, or controlled by use of the following:
Engineering controls: Strategies include changing the way materials and products are transported (eg, using mechanical assist devices for lifting or carrying heavy loads, changing to packages with handles or to packages with slotted hand holes, moving packages to areas that are easier to reach).
Administrative controls: Strategies include reducing the length of shifts, limiting the amount of overtime, and/or scheduling more breaks. Such strategies reduce the risk of work-related back injuries but do not eliminate the hazards that may cause them. Engineering controls are more effective, but administrative controls can help until engineering controls can be implemented or when engineering controls cannot be implemented.
Personal protective equipment (PPE): PPE includes back braces, back belts, and similar devices. Whether PPE can protect against ergonomic hazards is unclear. Although these devices may help, they may make it harder for workers to do the task (eg, a back brace may make doing a task that requires bending at the waist difficult).
Ergonomics: Ergonomics aims to reduce stress and eliminate injuries and disorders caused by overuse of muscles, bad posture, and repetitive tasks.
Work-related back injury (and resulting pain) is a common cause of worker absenteeism and loss of productivity.
Diagnostic evaluation for work-related back injury is similar to that of non–work-related back injuries and requires meticulous recording of details, including work-related details.
Plain x-rays have a notoriously low yield when used to image work-related back injury.
Imaging with CT or MRI is typically used for patients with neurologic deficits or findings suggesting fragility fracture.
Encourage early mobilization after a strain or sprain involving the back for the best clinical results and most rapid return to work.
