Q

Whats the next thing you should x-ray?

A

Pelvic Xray
(Bilateral and symmetric sacroilitis) because they have scral changes first before the back

22
Q

Whats the next thing you should x-ray after sacral?

A

lumbar spine
- Bone sclerosis
- Bamboo sign is present in <10% patients

23
Q

Lumbar disc hernation

A
  • Have sciatica
  • Don’t need surgery
  • H/o of recurrent LBP prior to sciatica
24
Q

What is the most sensitive test for disc herniation?

A

SLR
and positive crossed straight leg raise

(other side with no pain will cause pain on the effected side)

25
Positive SLR and CSLR
Less concerning bc its expected with disc herniation. if its with neuro defecits, then its concerning.
26
What are physical findings for lumbar disc herniation?
- Ankle dorsiflexion weakness, great toe extensor weakness, and decreased pinprick sensation are also clinically helpful
27
T/F lumbar spine imaging studies will reveal an asymptomatic anatomic disc herniation
True
28
When should you order MRI?
After 6 weeks after doing conservative symptoms. If they have more neuro syms earlier then order the dx imaging early
29
What is Spinal stenosis
Narrowing of the spinal canal leads to nerve impingement /cord compression
30
Spinal stenosis sx
pain in the legs, and sometimes neuro deficits, that occurs after standing or walking
31
How can you differentiate spinal stenosis from PVD?
check pulses, PVD will have decreased pulse
32
What is the average age surgical intervention for spinal stenosis?
age 55 and with 4 years of symptoms
33
T/F Spinal stenosis pain is provoked by bike riding
False, it does not cause pain when riding a bike
34
How does spinal stenosis progress?
Back pain slowly progresses to constant pain with leg “stiffness” or pain
35
T/F Pain in increased with spine flexion for spinal stenosis?
false, it is increased with spine extension
36
Whats the imaging for spinal stenosis?
L-spine or MRI or CT L/S WO contrast
37
What is cauda equina?
Massive midline disc herniation leading to spinal cord compression
38
Is cauda equina emergency?
YES YES
39
What is a factor for cauda equina?
disc herniation!!
40
Signs for cauda equina?
- Urinary retention (loss of bowel/bladder but LATE) - Anesthesia (saddle region anesthesia) - Decreased rectal tone ( - Sciatica - +SLR - Sensory and motor deficits
41
What is the next step for Cauda Equina?
- Emergent MRI - Emergent Neurosurgery consult
42
T/F is a good H&P does not cause any concerns for any of the backpain then no additional workup is required
TRUE
43
T/F No imaging or other diagnostic tests are needed initially in a patient with nonspecific low back pain.
True
44
When should you obtain spine imaging?
high risk pt with vertebral compression fracture - infection, cauda equina syndrome, progressive/severe neuro deficits - Risk factors for cancer - Radiculopathy or spinal stenosis - with progressive neuro symptoms with NO improvement after >6weeks.
45
What labs should you consider?
- ESR - CBC (maybe if they have infection or cancer) - Lactate, blood culture (maybe if they have infection or cancer)
46
Treatment for LBP?
Active - PT, massage, acupuncture, manipulation
47
What is pharm treatment for LBP?
- Combo active therapy with meds - first-line is NSAIDs or APAP - Second line muscle relaxers or antidepressants
48
What about other treatment of LBP?
- Topical meds - Trigger point injection - Nerve pain
49
What should you avoid with LBP treatment
Benzo's and opiates Benzo's are potent muscle relaxers, possible to do one dose of benzo (valium) to help relax/decrease pain to continue oral meds.
50
What is goal for LBP?
- Try to get back to baseline in 4 weeks - Walk 20min, 3-4 times a week - Re-eval in 4 weeks, sooner if uncontrolled pain, progressive symptoms - ER precaution
