Back Pain and Shoulder Flashcards
What are the 3 categories of back pain?
- nonspecific
- radiculopathy or spinal stenosis
- spinal pathology
What are the symptoms of MSK pain?
aches or cramps radiating across the back like a belt, won’t go past the thigh or hip
What are the symptoms of disc herniation?
radicular pain in a dermatomal distribution and extending below the knee. Exacerbated by valsalva, defecation, or cough.
At what level do 95% of disc herniations occur?
L4-L5 or L5-S1
What suggests L5 impingement?
Pain on the shins and great toe
weak dorsiflexion
What suggests S1 impingment?
Pain on the posterior leg
weakness planter flexion
What symptom makes a straight leg raise positive?
“electric shock” sensation from the hip down
Is the straight leg raise sensitive or specific for herniated disc?
sensitive (91%). Not specific.
Is the CROSSED straight leg raise (raising the UNAFFECTED leg causes pain in the AFFECTED leg) sensitive or specific for herniated disc?
specific (88%). Not very sensitive.
How does spinal stenosis present?
- severe bilateral leg pain.
- “pseudoclaudication”- Not worse with exertion, but is worse with prolonged standing or walking downhill.
- better with sitting
What are “red flags”/alarm symptoms for low back pain?
- History of cancer with new onset back pain
- Weight loss in age>50 yrs old
- Fever or recent infection
- IV drug use
- Urinary retention, incontinence, or fecal incontience, saddle anesthesia (cauda equina syndrome)
- History of osteoporosis, use of steroids (compression fracture)
- Morning stiffness, improvement with exercise, awakening back pain, alternating butt pain (ankylosing spond)
- Leg pain in derm distribution (L4=, L5=anterior leg, S1=posterior leg) and positive straight leg raise test (herniated disc)
- severe bilateral leg pain (spinal stenosis)
there are sensitive but NOT specific, so do NOT automatically warrant bigger evaluation
Rapid progression of neurological deficits is a sign of what?
spinal cord compression
how long do symptoms of back pain have to be present to consider MRI?
a month (4 weeks)
What is cauda equina syndrome?
compression of sacral nerve roots from a tumor or a herniated disc
what PE findings increase suspicion for psychosocial distressors?
- nondermatomal distribution
- pain with passive rotation of the spine
- pain on axial loading (press on head)
- straight leg raise test not positive with distraction
