Q

What is important to remember about the timing of a pt’s back pain?

A

-Nighttime Pain?? *worrisome for malignancy.

  • Early morning pain? RA, other autoimmune, OA.

Q

Why is it important to have your pt describe their back pain?

A
  1. Benign back pain is often “aching” or “burning.”
  2. Pathological back pain or non-spinal causes:
    - PANCREATITIS = “Burning or piercing” mid-back pain w/elevated amylase, lipase.
  • AORTIC DISSECTION = “Tearing” chest and mid-back pain; a surgical emergency.”
  • NEPHROLITHIASIS = Lumbar pain radiates to groin, “Colicky.” Hematuria, Renal CT.
  • PYELONEPHRITIS = Flank pain, provoked by percussion at CVA. Dysuria, Pyuria.
  • AUTOIMMUNE, INFLAMMATORY = Back and multiple involvement. Elevated ESR, ANA.

Q

Identify the Special Tests:

  1. Straight leg raising test.
  2. Crossed or Contralateral Straight Leg Raising Test.
  3. Internal/External Hip Rotation.
A
  1. To determine if a patient w/low back pain has an associated nerve root irritation or entrapment; such as the sciatic nerve.
  2. Straight leg raising test of the unaffected side; if Sx reproduced…highly associated with herniated disc and sciatic radiculopathy (about 97% of the time).
  3. Will identify if the pain is coming from the hip.

27
Presentation of Facet Syndrome?
1. Chronic LBP not responsive to traditional mgmt. | 2. May have increased pain w/side bending.
28
Protrusion or Extrusion of a intervertebral disc? What can happen with this condition?
Herniated Disc can cause compression of a spinal nerve.
29
Most common location (not vertebral level) of a herniated disc?

31
Narrowing of the spinal canal?
Spinal stenosis. **Compresses the spinal nerves.
32
Emergency complication of Spinal Stenosis?
Compressing of the Cauda Equina (Cauda Equina Syndrome).
33
Presentation of Spinal Stenosis?
1. Pain, paresthesias of legs with lack of stamina in legs. 2. WORSE STANDING OR WALKING, BETTER SITTING. 3. Neurogenic Claudication.

What vertebral levels is the cauda equina located?
L1-L5.
36
What is another name for neurogenic claudication and what is it?
Pseudoclaudication; compression of the nerves in the lumber region causing leg pain, more specifically, difficulty or weakness with walking.
37
Why is pain worse with standing or walking and better with sitting in Spinal Stenosis?
When you sit, the SC opens up. When you sit, the SC narrows.
38

41
Why do the symptoms of Cauda Equina manifest?
The cauda equina houses the sacral plexus (S1-S4) which innervate the pelvic muscles, perineum and organs in the pelvis.
42
A "slip" of one vertebra with respect to another?
Spondylolisthesis.
43
What is the cause of Spondylolisthesis...aka the "slip" and what may it cause?
A fracture of the pars interarticularis. It may cause Spinal Stenosis or pinch a spinal nerve.
44
What is the pars interarticularis?
Also 'pars' for short, is the part of a vertebra located between the inferior and superior articular processes of the facet joint. It is an area most stressed by translational movement between the adjacent segment.
45
Presentation of Spondylolisthesis?
1. Local low back pain. 2. Better lying. 3. With or without radiculopathy or neurogenic claudication. **More of a bony back pain.
46
An abnormal curvature of the spine in the coronal plane?
Scoliosis.
47
What may also be associated with Scoliosis?
Abnormal sagittal kyphosis -- Kyphoscoliosis. *Abnormal curvature of the spine in two planes; the coronal plane (side to side) and the sagittal plane (back to front).
48
Presentation of Scoliosis?
1. Back pain. 2. Rotation of rib cage. 3. Uneven hips.
