no, more nerve root impingement

night sweats pn at night pn at rest unexplained weight loss failure to improve with therapy severe pain for 6+ weeks urinary/bowel incontinece/retention (cauda equina)
is LBP 2nd most sought visit to primary care?
true , LBP most common cause of diability in pt under 45
how quickly do most LBP resolve?
80% in 2 weeks
90% in 6 weeks
risk factors for LBP due to cancer
history of cancer
50 y.o. +
cauda equina S&S
urinary retention/incontinence (bowel too)
decreased anal spincter tone
bilateral LE weakness
progressive neuro involvement
risk factors of LBP due to compression fractures
70 y.o.+
corticosteroid use
osteoporosis
recent trauma
one leg standing test then extend spine tests for what?
PARS interarticularis fracture (spondylosis or spondylolisthesis)

major trauma minor trauma if 50+ osteoporosis long-term corticosteroid use 70 +
if SLR, and pain contralateral leg lifted? what is problem?
Large disc herniation
if ipsilateral leg (sciatica, neural foraminal stenosis)
Conservative Treatment of LBP
pt education (lifting techniques)
core strength
heat/cold for temporary relief (not long term)
NSAID- effective early on
Muscle relaxants- if true muscle spasms, not if protective spasm
opiods- Alpha-2-delta ligans (gabapentin), serotonin-norepinepthrine reuptake inhibitor (duloxetine), or tricyclic antidepressants (nortriptyline)
non-conservative treatment of LBP
better prognosis if anatomic lesion is fixed
when to refer LBP
Cauda equina syndrome
Cancer, infection, severe spinal deformity
not respond to conservative care
