Pathoanatomy

With LBP with Radiating pain, what two conditions can affect the HNP?

A

Degenerative Changes to the Annulus Fibers
- Prolonged exposure to hypo- or hyper- loading correlates with disc degeneration
- Degeneration and weakening of the annulus allows the nucleus material to bulge and migrate outside the annulus margins

Failure in the integrity of annulus fibrosis integrity
- Sudden unguarded movement, often flexion with torsion
- Protrusion or herniation into the neural canal, intervertebral foramen or lateral to the foramen

A

Morning

Noon to evening

17
Q

What is the 24hr pain behavior for Lateral Foraminal and Central Canal Stenosis?

A

Morning
- Sleeping in lumbar extension or in a LE position that tensions the nerve root, they may wake up with leg pain

Noonn to evening
- Sx will vary throughout the day depending on the patient’s activities

Night
- Sleeping in lumbar extension or in a LE position that tensions the nerve root, they may wake up with leg pain
- Neuropathic pain is often worse at night
- May have disrupted sleep

18
Q

What should take place in the Neurological Examination?

A

DTR’s
- Quads, and Achilles

Dermatomes
- L3-S1
- Sharp/Dull

Myotomes
- L3-S1

19
Q

During the Movement and Provocation examination, what would you see with Active ROM?

A

ROM limitations and Sx provocation will depend on individual patient presentation
- Extension loss
- Centralization

The movements and positions that result in peripheralizing or centralizing leg pain should be noted and will depend on whether the patinet has a disc herniation or stenosis.
- Patients with HNPs will have Sx with lumbar flexion and centralized lumbar extension
- A HALLMARK of patients with HNP is they initially have a significant loss of extension that will rapidly restore once they perform repeated or sustained lumbar extension
- Patients with Stenosis of leg Sx with extension and centralization with flexion based movements. This will occur either bilaterally or unilaterally depending on the type of lumbar stenosis

20
Q

During the Movement and Provocation examination, what would you see with PIVM?

A
  • Hypomobility and Sx reproduction at the involved segments
  • Possible hyper- or hypomobility at adjacent segments

  • For patients with disc herniations, the PIVM assessment may reveal segmental reproduction in the lumbar spine and LE
  • For patients with stenosis, the involved segements may be hypomobile or in cases of an unstable spondylosthesis, could be hypermobile and can elicit local and distal Sx reproduction
21
Q

What test are part of the Neurodynamic Testing?

A

These are mostly for HNP, although they can reproduce both lateral foraminal and centtral canal stenosis
- Straight Leg Raise (SLR)
- Cross Straight Leg Raise
- Slump Test
- Femoral Nerve Tension Test (Ely’s Test)

22
Q

What was the Diagnostic Cluster developed to determine which patients have Lumbar Spinal Stenosis?

A

Cooks Cluster (Lumbar Spinal Stenosis)
- Bilateral Sx
- Leg pain > Back pain
- Pain during standing and walking
- Pain relief upon sitting
- Age >48 years old

23
Q

What is LSS?

A

A common degenerative condition associated with narrowing of the spinal canal or nerve root canals caused by degenerative arthritic changes of the facet joints and intervertebral disks

24
Q

With patients with LBO with Radiating Pain, what is the clinical importance of performing the Two Stage Treadmill Test with those with Lumbar Spinal Stenosis?

A

We must determine the cause of Sx for those who have bilateral LE pain with walking and reduces with sitting

They may have:
- Neurogenic Claudication: Pain, paresthesia, and cramping of the LE brought by walking and relieved by sitting. This should be more affected by the position of the spine during the LE exertion. A positive test results for neurogenic is a demonstration of greater tolerance for walking in an inclined position, which places the spine in flexion
or
- Vascular/Intermittent Claudication: From peripheral vascular disease. This must be screened before a diagnosis of spinal stenosis can be made. This should be only affected by the level of LE exertion and the demands of blood flow to the LE muscles

25
Q

Why might LSS result in leg Sx?

A

Due to compression on the vertebral venous plexus from multi-level stenosis that creates venous pooling and congestion and leads to ischemic pain and fatigue in the LE during walking

26
Q

What movement is typically limted with LSS? What movement alliviates pain?

A
  • Spinal Extension is commonly limited
  • Sitting or assuming a spinal flexion (forward bent) position often
27
Q

What are the 7 Hx items that can be used to help Diagnose LSS?

A
  • Leg or buttock pain while walking
  • Flex forward to relieve Sx
  • Feel relief when using a shopping cart or bicycle
  • Motor or sensory disturbances while walking
  • Normal and symmetric foot pulses
  • LE weakness
  • LBP
28
Q

What is the Clinical Course and Prognosis of LBP with Radiating Pain?

A
  • Self-limiting with a favorable prognosis with resolution of Sx occuring weeks to month
  • 70-90% of patinets exerience improvement without surgery
  • Most patients will see Sx improvement over time
  • Sx centralixation is a Positive prognositic indicator
  • Spontaneous resolution of disk herniations are common
  • Motor and sensory deficits will improve at different rates
  • patients should be monitored for several progressive neurological dysfunction
