  • Absence of neuro deficits
25
Q

Are x rays indicated in acute pt. with uncomplicated LBP, T pain?

A

No

26
Q

Are x rays initially indicated with Subacute or Chronic LBP, T pain and no previous Tx trial?

A

No

  • No prior tx –> trial period of 4-6 weeks is recommended
  • Absence of expected response or worsening after 4-6 weeks –> take films
27
Q

Pt. has nontraumatic acute LBP and Sciatica (suspicion of disc herniation). You shouldn’t take films unless…

A
pt is >50
progressive neuro deficits
unexpected response to care 4-6 weeks
worsens with care
*MRI would be of value
28
Q

What are the signs of disc herniation?

A

-Need 3 of 5 (consistent to same N. level)
primarily leg pain
leg pain confined to dermatome
Neural stretch tests recreate or exacerbate leg pain
2 of 4 neuro findings consistent w/ dermatome
-muscle weakness
-decreased reflex
-Abnormal Pinwheel
-Atrophy
MR or CT correlating to Dermatome

A

Yes

30
Q

comes and goes
often reduced by leaning forward or sitting down
no neuro findings
very common
4 Fs --> Fat, Female, Forty, L4
31
Q

38
Q

Cervical Spine Views and accessory views

A

AP, APOM, Lateral

Flexion/Extension (motion, ligament lax, ADI)
Obliques (Pedicles, Pillars, IVF)

39
Q

Thoracic Spine Views and accessory views

A

AP and Lateral

Accessory views are rare, instead use special imaging

40
Q

Lumbar Spine Views and Accessory views

A

AP(PA) and Lateral. Some say Sacral Tilt also.
Sacral tilt –> SI and lumbosacral junction

Obliques –> pars, lamina, soft tissue (kidney stone vs. gall stone)

  • Post oblique: Ant structures move further from spine and post. structures move closer to spine
  • Ant obliques: post. structures move farther from spine and ant. structures move closer to spine
41

Hip Views and Accessory views

A

AP and Lateral

Special Imaging preffered for accessory fields

42
Q

Knee views and accessory views

A

AP and Lateral

Tunnel: See intercondylar notch

43
Q

Ankle views and accessory views

A

AP, lateral, oblique

Special imaging preferred for accessory fields

A

AP, lateral, oblique

Special imaging preferred for accessory fields
