Spinal Column Disorders Flashcards
Cervical Strain
● Although the term “strain” generally refers to injury of
muscle tissue, the term “Cervical Strain” includes
ligamentous injury of the facet joints and/or
intervertebral disks, in addition to muscle injury.
○ “Neck sprain” is synonymous
Common etiology of cervical strain
whiplash injury
Cervical Strain pathophysiology
○ Whiplash injuries occur with rapid
acceleration and/or deceleration,
which results in rapid flexion and
extension of the cervical spine.
○ The velocity of the movements can
stretch and tear muscles, disrupt
ligaments, dislocate facet joints, and
cause spinal fractures.
○ Cervical instability can develop.
Cervical Strain Clinical Presentation
○ Cervical pain that begins after an accident or trauma, but can start spontaneously (even during sleep).
○ The pain does not radiate into the arms or down the spine.
○ Diffuse pain anywhere from the base of the skull to the cervicothoracic junction is most common.
○ Pain is often increased with motion and may be accompanied by muscular spasm in the sternocleidomastoids, trapezius muscles, or paraspinals.
○ Occipital headaches may occur and may persist for months
Cervical Strain PE
○ Exam may reveal tenderness to palpation of the sternocleidomastoids,
trapezius muscles, or paraspinals secondary to muscle spasm.
○ Tenderness may be noted over the spinous processes and facets
Cervical Strain diagnosis
○ Pain often limits range of motion.
○ The neurologic examination should be normal
■ No Lhermitte’s sign (electrical pulse through body with neck flexion)
■ No Spurling sign (radiating pain down arm with lateral bending)
■ No pain or paresthesias into the arms or down the spine AP, Lateral, and Odontoid (open-mouth) X-rays should be obtained if there is a history of trauma, associated neurologic symptoms, or if the patient is elderly
○ If severe pain, Flexion and Extension films (aka
Flex/Ex films) should be obtained, but should be
ordered by a consulting specialist
Cervical Strain Managemen
○ Most patients return to normal within 4-6 weeks
○ Acetaminophen and NSAIDs are preferred, although a short course (no
more than 1 week) of narcotic may be needed.
○ 1-3 weeks in a Soft Cervical Collar is often beneficial.
○ 1-2 weeks of Muscle Relaxants can be beneficial.
○ Manipulation of the cervical spine is contraindicated
in patients with acute cervical spine injuries!
Acute Low Back Pain
● Acute LBP is more of a symptom than a diagnosis. However, 80%+
of LBP patients are not able to be given a more specific diagnosis.
○ Acute = LBP of less than 3 months in duration.
● Lifetime prevalence in the US is 60-80%.
● Of all cases of acute LBP, 70% are secondary to
lumbar sprain or strain
Acute Low Back Pain pathophuysiology
○ Lumbar strain is an injury to the paravertebral
spinal muscles.
○ Lumbar sprain refers to ligamentous injury of
the facet joints or annulus fibrosus,
transvertebral or other spinous ligaments.
○ Age-related facet or vertebral arthropathy can flare if provoked acutely by certain movements or lifting
Acute Low Back Pain presentation
○ Patients often report an acute onset of LBP after lifting or twisting
○ Low back pain may radiate down into the buttocks.
○ Even though lifting or twisting is a common
cause, patient who are sedentary also
frequently experience LBP (poor fitness,
sitting at computer).
○ May have difficulty standing up straight
and transitioning from position to position.
○ Patients often have diffuse tenderness to palpation in the lumbar region and/or sacroiliac area
○ Lumbar range of motion is often decreased
secondary to pain.
Acute Low Back Pain diagnosis
○ The goal is to identify the serious causes of low back pain and know when it is necessary to order radiologic imaging.
○ Because most have strain or sprain, plain X-rays are usually not helpful and need not be ordered for all cases of LBP
○ If significant pain at rest, pain at night, or history of trauma,
ordering X-rays (AP and Lateral) would be appropriate.
Acute Low Back Pain management
○ As long as the patient has no sciatic symptoms or significant neurologic deficit,
treatment of acute LBP (most commonly strain or sprain) has 2 phases:
“Essentials of Musculoskeletal Care,” 5e. Armstrong, Hubbard.
■ Phase 1- Focus on Symptomatic Relief
■ Phase 2- Focus on Return to Activity
Chronic Low Back Pain
● Chronic LBP is defined as LBP that lasts for 3+ months.
● Symptoms are most commonly recurrent and episodic,
but for some the pain is unrelenting
Once Chronic LBP has been identified, a thorough evaluation should occur, ruling out the following:
○ Cancer (metastatic or primary)
○ Osteoporosis with fractures
○ Osteomyelitis and discitis (infection)
○ Abdominal pathology (aneurysm, retroperitoneal tumor)
Chronic Low Back Pain pathophysiology
○ The most common cause of Chronic LBP is
degenerative disc disease.
○ Other causes include:
■ Lumbar stenosis
■ Ankylosing Spondylitis
■ Old vertebral fractures
Chronic Low Back Pain clinical presentation
○ Chronic low back pain that radiates to one or both buttocks.
○ Pain is aggravated by activity (lifting, bending, twisting, etc).
○ Patient may have history of intermittent sciatica (radiating down the back of the leg), but back pain is the predominant symptom.
○ Rest helps to relieve the pain for most patients.
■ Some have difficulty sleeping because of the back pain
○ Progressively worsening back pain with weight loss is a red flag for cancer and should not be ignored
Chronic Low Back Pain evaluation
○ On examination, there may be diffuse
tenderness to palpation in the lumbar and
sacroiliac regions
○ Neurologic exam of the LEs should be normal.
○ Range of motion may be restricted.
○ X-rays (AP and Lateral) will reveal age-related
degenerative changes.
X-ray findings of chronic low back pain
■ Osteophytes with decreased disc height
■ May see spondylosis/spondylolisthesis
Narcotic abuse or misuse is a large concern in this group
Chronic Low Back Pain
Spinal Fractures pathophysiology
○ High-velocity impact, hyperextension,
hyperflexion, or hyper-rotation can all lead
to vertebral fracture
○ If the central canal or neural foramen are
compromised, neural tissue may be injured
(spinal cord or spinal nerves).
○ Osteoporosis and bony metastasis can
result in “insufficiency” fractures.
Spinal Fractures clinical presentation
○ Spinal pain is generally severe, even at rest.
○ Other symptoms depend on presence or absence of neural tissue compression
■ Spinal cord damage will result in paresthesias
and loss of motor control below the level of
the injury.
■ Nerve root impingement will result in pain and paresthesias along the associated dermatome (potentially motor loss)
Spinal Fractures evaluation
○ Evaluate motor and sensory function throughout all cervical, thoracic, and
lumbar dermatomal/myotomal distributions.
○ Assess deep tendon reflexes for presence and symmetry.
○ Examine for swelling and contusions over the spinal column.
○ Palpate for point tenderness and step-off lesions (posterior ligament injury)
Radiologic Imaging of Spinal Fractures
■ Plain X-rays are an option and often reveal the injury.
■ However, if significant trauma or abnormal examination, CT scan is the initial imaging modality of choice in most trauma centers.
● Provides better images with more definitive diagnosis (and faster)
■ MRI is obtained after the CT if there is a concern for neural tissue compression and ligamentous injury
Spinal Fractures management
○ If imaging studies reveal no evidence of fracture, and neurologic exam is
normal, spinal precautions may be lifted after confirmation by a
neurologic or orthopedic specialist.
○ If a spinal fracture is identified, urgent consultation by a specialist is
standard of care
The three main goals of spinal fracture treatment are:
■ Prevent Neurologic Injury
■ Restore Stability
■ Restore Normal Function
Sciatica
● Sciatica is sharp, shooting, radiating pain
(sometimes with accompanying paresthesias) that travels through the buttock, down the posterior thigh, past the knee, and into the calf and even foot
Common causes of Sciatic compression
■ Herniated Nucleus Pulposus (disc)
■ Lumbar Spinal Stenosis
■ Traumatic Pelvic Fracture
■ Piriformis Syndrome
In severe cases of _____, foot drop may be
present
sciatica
