MSK/Rheumatology - Spinal Disorders - Exam 3 Flashcards
What are some of the risk factors for spinal disorders?
Poor physical conditioning, poor posture or body mechanics, occupational exposure, older age, obesity, pregnancy, and poor abdominal musculature
What XR views are essential in cervical trauma?
AP, Lateral, Odontoid, Swimmers view, and Oblique
What are the indications for lumbar XR?
Fall from height greater than 3 meters, fall from standing > 60 years or frail, MVA, Significant trauma, acute/severe back pain, history of CA, or neurological deficits
What XR view is used to visualize lumbar articular facets and pars interacrticularis?
Oblique
What XR view is used to visualize spinal stability and rule out spondylolisthesis?
Flexion-extension
What XR is used to visualize the alignment and look for infection, malignancy, fractures, and degenerative changes?
AP and lateral
What imaging is best for evaluating the spinal cord, nerve roots, meninges, disc abnormalities, or post op study?
CT myelogram (spinal canal is injected with contrast)
When are bone scans indicated?
For infectious or metastatic disease
What does Electromyography do?
Detects response of muscle to nerve stimulation
What does a nerve conduction study to?
It can determine specific site of nerve injury
What are the two types of neurophysiology studies?
Electromyography (EMG) or Nerve Conduction Study (NCS)
Which neurons are located in brainstem and corticospinal tracts of the spinal cord. They
initiate voluntary movement and maintains muscle tone.
Upper motor neurons
Which neurons are located in the spinal cord gray matter and the motor nuclei of cranial nerves. They stimulate skeletal muscle and produce movement.
Lower motor neurons
What is compression of or damage to the spinal cord which leads to tissue ischemia called? (upper motor neuron)
Myelopathy
What are the most common cause of myelopathy?
Spinal stenosis
What is a neurologic deficit related to the spinal nerve root called? (lower motor neuron)
Radiculopathy
What are the most common cause of radiculopathy?
Neuroforaminal narrowing
Does myelopathy or radiculopathy cause symptoms below the lesion?
Myelopathy
What is a shock-like sensation radiating into spine or arms with forward flexion of the neck called? What is it seen with?
Lhermitte sign
Myelopathy
Weakness, loss of sensation, increased muscle tone, hyperreflexia, up going plantar reflex, clonus, and muscle atrophy are often seen with what?
Myelopathy
Does Myelopathy or radiculopathy cause symptoms in a dermatomal pattern?
Radiculopathy
Hypotonia, hyporeflexia, areflexia, weakness, muscle atrophy, muscle fasciculation are often seen with what?
Radiculopathy
Strain indicates injury to what 3 things?
Muscle, tendon, and musculotendinous junction
A sprain indicates an injury to what?
Ligaments
