Low Back Pain (Acute)
report of acute low back pain (ALBP), although
quite common, requires a thorough evaluation.
A
frequently multifactorial and includes both physiological
and psychological components. The most common
causes of ALBP relate to musculoligamentous injuries
and age-related degenerative processes. About 90% of
ALBP episodes in adults are related to mechanical causes
that resolve within 4 weeks without serious sequelae. A
smaller percentage of patients will continue to have
chronic symptoms without organic pathology or will
have underlying disease.
with age and with involvement in sports. Anthropometric variations in children place them at risk for
excess strain on the spine, producing back pain. These
variations include reduced hip mobility, decreased
lumbar extension and increased lumbar exion, poor
abdominal muscle strength, tight hamstring muscles,
and lumbar hyperlordosis.
lower back or back-related leg symptoms of less
than 3 months’ duration. The Agency for Healthcare
Research and Quality (AHRQ) guidelines provide the
following framework for causes of ALBP:

n Sciatica, or leg pain and numbness of the lateral

strain, diskogenic pain, or bony deformity secondary to inammatory disease
ment (e.g., gallbladder, liver, renal, pelvic inammatory disease; prostate tumor; ovarian cyst; uterine
broids; aortic aneurysm; or thoracic disease)
ment (e.g., disability, workers’ compensation, secondary gains)
When evaluating ALBP, the goal of the clinician
is to rst identify signs and symptoms of potentially
serious conditions through a careful history and
physical examination. A holistic approach to the
patient is needed to appreciate the extent to which
pain affects the patient’s daily routine or workrelated activities. Because ALBP is a common
occupation-related complaint and a cause of disability and lost productivity, the clinician must
gain insight into the psychosocial and economic
situation of the patient to help arrive at a correct
diagnosis.
DIAGNOSTIC REASONING:
FOCUSED HISTORY
Is this a potentially serious cause of ALBP?
Key Questions
n Do you have a fever?
n Have you experienced any trauma to the spine or
back?
n Do you have any other health problems?
n Have you been treated for cancer?
n What is your age?
n Have you had loss of control of your bowels or
bladder?
n Are you taking any medications?
Fever
The presence of a fever indicates an inammatory
condition such as spondyloarthropathy or systemic
infection. Infection is a likely diagnosis when there
are chills and fever, weight loss, a recent history of
bacterial infection, intravenous drug use, or an immunosuppressed patient. Ewing sarcoma is a malignant
tumor and can mimic spinal infection, occurring as
back pain that can be accompanied by fever. Children
with diskitis will have a fever and refuse to walk
because of back pain.

Trauma
Acute trauma to the spinal cord can result in fracture,
dislocation, or misalignment of muscles, ligaments,
and intervertebral disks. Trauma may be caused by
blunt impact, repetitive injury, or sudden stress caused
by lifting or pulling. Low back pain is the most common occupational injury reported. Injury to the back
usually results in contusions and abrasions but can
also cause spinal fracture if the force is major, such as
that sustained in a motor vehicle accident or fall. In
the elderly, an acute spinal fracture might result from
strenuous lifting when osteoporosis is present. Injuries
to the posterior structures of the spine account for
most cases of low back pain in adolescents who are
athletically active.
Injury to the spinal column should be suspected in
anyone whose level of consciousness is impaired after
an accident. Cervical spine fractures are sustained
during exion, extension, compression, rotation, or a
combination of forces.
Age
In the absence of trauma, the sudden onset of severe low
or middle back pain in persons older than 30 years might
suggest a dissecting aortic aneurysm. The pain will not
be alleviated by rest. Patients older than 50 years are
at increased risk for compression fracture as well as
cancer.
Systemic Disease
Metabolic disease, inammatory disorders, and bromyalgia can lead to back pain. Patients with a history
of cancer may have increased risk of a spinal tumor.
Neuroblastoma is common in young children, and

Chapter 21 • Low Back Pain (Acute) 269
https://t.me/med1917
although it occurs in the abdomen, metastases to the
spine may produce back pain. Systemic disease may
also be accompanied by unexplained weight loss.
Persons younger than 20 years and older than
50 years are at increased risk for tumor, as are those
with a history of cancer.
Bowel and Bladder Symptoms
Loss of urinary or stool continence indicates cauda
equina or S1-S2 nerve root compromise secondary to a
herniated disk, nerve root entrapment, spinal stenosis,
infection, or tumor. Constant lumbar puncture with
saddle anesthesia, urinary retention, and fecal incontinence are symptoms of cauda equina syndrome, which
is considered a surgical emergency.
Children are embarrassed to talk about urinary or
bowel habits and changes. Hidden spinal cord tumors
might have a relationship to developmental delays
in bladder and bowel control. Children under 4 years
of age who have back pain should be evaluated for
serious diseases, such as intraspinal tumors, dermoid
cysts, and malignant astrocytomas.
Medications
Long-term use of corticosteroids can lead to compression
fractures of the vertebrae. Use of intravenous drugs may
suggest infection as a cause.
What does the location of pain tell me?
Key Question
n Where does it hurt?
Location of Pain
In general, children are less specic than adults when
describing location of pain. Traumatic lesions are more
likely to occur in the cervical and lumbar portions of
the spine, where there is more motion and less protection. Generalized pain or pain over a fairly wide anatomical area is frequently seen with overuse problems
and inammatory conditions.
Sciatica pain is a sharp, burning pain that radiates
down the posterior and lateral leg to the foot or ankle.
Back pain with neck stiffness can indicate cervical osteomyelitis. Rheumatoid arthritis produces pain in the upper
back and neck. Localized pain is seen with spondylolysis
and tumors. Flank pain in adults may indicate a kidney
infection. Pain of gallbladder disease radiates to the
subscapular areas. Compression fractures of vertebrae
associated with osteoporosis or malignancy may produce
pain over the midthoracic area.
Children with traumatic low back derangement will
have pain and muscle spasm in the lumbar area from
the pressure and shock of an impact injury collision.
What does the pattern of pain tell me?
Key Questions
n When did the pain start?
n How long have you had this pain?
n What does the pain feel like?
n Does it interfere with sleep?
n Have you had this pain before?
Onset
The onset of ALBP is sudden, and more than half of
patients with this symptom do not associate it with a
specic precipitating event or injury. The vast majority
of cases of ALBP resolve with conservative treatment
in 4 weeks, and radiographic or further diagnostic studies are not recommended until then.
Children are frequently poor historians and parents
may have a difcult time remembering when the pain
started. Association with events such as birthdays,
holidays, and activities is helpful in establishing the
onset of the pain. Pain that is mild and of short duration
(1 to 2 weeks) is rarely serious.
Back pain lasting longer than 4 weeks needs to be
reevaluated for further diagnostic studies.
Duration
Subacute back pain is of 6 to 12 weeks’ duration.
Chronic back pain is pain of more than 3 months’ duration. In persons under 40 years of age, the cause may be
postural or may indicate congenital spinal deformity,
such as scoliosis or ankylosing spondylitis. In older
persons, chronic back pain is more likely to indicate
degenerative disease, such as spinal stenosis or disk
herniation. In children, back pain present for more than
3 weeks is often due to organic and serious causes.
Pain Characteristics
In children, expression of pain depends on the child’s
ability to put feelings of pain into behavior; observing
for these behaviors is important. Ask children to rate
the pain using a 10-point pain scale with happy to sad
faces (see Chapter 2). Ask adults to rate pain from
0 (no pain) to 10 (worst pain ever) and assess how

270 Chapter 21 • Low Back Pain (Acute)
https://t.me/med1917
much the pain interferes with daily activities. Intractable back pain, especially night pain with constitutional ndings, is likely to indicate neoplastic disease.
Painful scoliosis and stiffness are common presenting
symptoms of a spinal tumor.
Night Pain
Nighttime back pain is a worrisome symptom that often
signals a serious problem, such as tumor, infection, or
inammation. Generally, muscle pulls, overuse injuries,
spondylolysis, spondylolisthesis, and Scheuermann disease (an exaggeration of the normal posterior convex
curvature of the thoracic spine) produce less pain at
night. Morning stiffness that improves as the day progresses suggests ankylosing spondylitis.
Nighttime back pain is unusual and indicates the
need for a complete and thorough workup.
Recurring Pain
Back pain in young children who have had previous
injuries or fractures may be a symptom of child abuse.
In the older adult, it may be an indication of compression fractures of the spine. As with young children, it
may also signal abuse by a caregiver.
Any child who has voluntarily given up a plea-
surable activity because of back pain has a severe
symptom.
Alleviating Factors
Back pain not associated with any activity and not
relieved by rest may indicate tumor. Back pain relieved
with aspirin or nonsteroidal anti-inammatory drugs in
children may indicate an inammatory cause. Pain that
is alleviated by rest and heat indicates a musculoskeletal cause. Pain of spinal stenosis is relieved on exion
of the spine.
Suspect spondylolisthesis, or forward slippage of
one vertebra over another, if the onset of pain is during
hyperextension, such as with a back handspring, buttery stroke in swimming, or a tennis serve. The defect arises from a stress fracture or stress reaction of
the isthmus of the pars interarticularis in the area of
L5-S1. The pain localizes to the low back and occurs
during a growth spurt and after engaging in sporting
events. The pain improves with rest and is worse with
standing.
What does radiation of pain tell me?
What does the pain in relation to activity
tell me?
Key Questions
n What makes the pain worse?
n What makes the pain better?
Aggravating Factors
Pain experienced in the lumbar area occurring after
strenuous sporting activities is usually the result of
trauma to the muscles and tendons, causing contusions
and sprain. It occurs when the patient pushes the muscles and ligaments past the normal level of tolerance.
Repeated injury can cause soft tissue scarring and
shortening.
Stress and fatigue fractures of the pars interarticularis, the region between the superior and inferior articulating facets of the vertebra, occur when lumbar lordosis
places more stress on the pars, such as in gymnastics and
tennis.
Pain that is aggravated by activity is usually musculoskeletal in origin. Pain of ankylosing spondylitis is
relieved with exercise. Spinal stenosis is associated with
increased pain with standing, sneezing, or coughing.
Key Questions
n Does the pain travel?
n Can you show me where the pain travels?
Radiation of Pain
Referred pain is of two types: (1) pain referred from
the spine into areas lying within the lumbar and upper
sacral dermatomes; and (2) pain referred from the
pelvic and abdominal viscera to the spine. Pain from
the upper lumbar spine usually radiates to the anterior
aspects of the thighs and legs, and that of the lower
lumbar spine radiates to the gluteal regions, posterior
thighs, and calves.
Pain from visceral disease is usually felt within the
abdomen or anks. Gallbladder pain radiates around
the trunk to the right scapula. Position does not affect
the pain.
Persons with spondylolysis, a destruction of vertebral structure, or spondylolisthesis, an anterior displacement of a vertebra, report hamstring tightness and
buttock discomfort as well as low back pain.
Pain that is sharp and burning and radiates down the
lateral or posterior aspect of the leg to the lateral ankle
or foot is called sciatica, and is a classic symptom of
