Spine MSK/Pain Flashcards
Steroid that is more likely to cause tissue atrophy with injection of superficial structures?
Triamcinolone
What type of allergy can interfere with hyaluronic acid injections?
bird products (eggs, poultry, feathers)
What are the natural curves of the spine?
- cervical lordosis
- thoracic kyphosis
- lumbar lordosis
- sacral kyphosis
What is “transitional anatomy” in the lumbar spine?
some people have sacralization of the lumbar spine or lumbarization of the sacrum resulting in 4 or 6 lumbar vertebrae respectively.
Does having “transitional anatomy” in the lumbar spine necessarily cause pain or is it a normal varient?
normal varient
What does the nucleus pulposus consist of?
Type II collagen, water, and other materials
What type of collagen makes up the annulus fibrosis?
type I
What nerves innervate the C4-C5 facet joint?
C4 and C5 medial branches of dorsal rami
What nerves innervate the L3-L4 facet joint?
L2 and L3 medial branches of dorsal rami
What provides innervation to the nucleus pulposus?
nothing, it lacks innervation.
What provides innervation to the annulus fibrosus?
- anterior: ventral rami
- posterior: sinuvertebral nerves
What provides innervation to the vertebral body?
sinuvertebral nerves
When is surgery indicated for a vertebral body compression fracture?
- greater than 25% loss of disc height
- spine is unstable
- significant neurologic deficits
What defines the middle column of the spine?
Posterior 1/3 of the vertebral body to the posterior longitudinal ligament
When is a spine unstable?
dammage to the middle column or any 2 columns
How does neurogenic claudication present?
- leg or buttock pain/weakness
- worse with prolonged standing
- worse with spinal extension and relieved with flexion
How does vascular claudication present?
- calf pain worse with activity (walking uphill, biking)
- skin changes (thin, shiny, hairless)
- diminished/absent pulses
Treatement for spinal stenosis
PT with directional preference assessment (flexion biased) or surgical decompression
Most common cause of spondylolisthesis?
Isthmic (Class II): fracture of pars interarticularis
How do you grade spondylolisthesis?
Treatment for spondylolisthesis?
- Grade 1, 2, and asymptomatic grade 3: rest and PT
- Symptomatic grade 3 or grade 4: surgery
What triggers SI joint pain?
transitional movements (sit to stand)
What does bilateral sacroiliitis indicate?
Ankylosing spondylitis
What type of radiculopathy will a L3-L4 central or posterolateral herniation cause?
L4
What type of radiculopathy will a L3-L4 lateral or neuroforaminal disc herniation cause?
L3
What type of radiculopathy will a C6/C7 disc herniation cause?
C7
What defines a disc bulge?
Disc tissue extending beyond the edges of the vertebral apophyses without displacement of disc material (nucleus)
What are the three types of disc herniation?
prolapse, extrusion, sequestration
What defines a disc protrusion?
displacement of disc material beyond the disc space with measure at base greater than apex
What defines a disc extrusion?
displacement of disc material beyond the disc space with measure at the apex greater than at the base
What defines a disc sequestration?
disc material has lost all connection with disc of origin
What is a schmorl node?
How are superior to inferior levels within a vertebral body defined?
In relation to the pedicle
How do we define the zones that a disc can herniate into?
What are the three types of annulus fissures?
`
What is the return to work expectation (%) for a patient who has missed six months due to low back pain?
50%
what is an uncovertebral joint (joint of Luschka)?
disc degeneration creates raised superior lateral vertebral body margins (uncinate processes) that approximate with the vertebra above
