Q

What is the difference between somatic referred pain and radicular pain?

A

referred pain is nociception generated by a skeletal or related structure and is perceived in an area distant to the structure generating the nociception

radicular pain arises from the dorsal root or dorsal root ganglia and is referred along a portion of the course of the nerve formed by the affected dorsal root

Q

What is the mechanism of radicular pain?

A
  • pressure on the dorsal root or DRG causes edema within the nerves
  • prolonged edema and hemorrhage within the DRG results in decreased blood flow to sensory nerve and cell bodies

Q

What effect might the loss of muscle spindles play in the development of scoliosis? Pineal gland?

A

muscle spindles play an important role in proprioception, kinesthetic input, and postural tone; loss of muscle spindles may cause the development of scoliosis

the pineal gland releases serotonin, which is important in the metabolism of spine growth

112
Q

Conservative Management for structural scoliosis

A
  • orthotic bracing
  • Milwaukee brace, Boston brace system, Wilmington Brace
  • 74% success rate (i.e. prevention of further progression)
113
Q

Milwaukee Brace

A

> 5˚ progression per 6 mos. OR angle = 20-30˚

114
Q

Conservative Management (Exercise) for structural scoliosis

A
  • posture
  • strength - trunk, extremities
  • ROM
  • leg length
  • breathing pattern (i.e. diaphragmatic)
  • functional activity method
  • SCHROTH METHOD
115
Q

Appropriate candidates for surgical management of structural scoliosis:

A
  • failed conservative treatment
  • > 40˚ curve in patients who are still growing
  • > 50˚ curve following bone growth cessation
116
Q

What two factors determine the stability of thoracic spine fractures?

A
  • the integrity of the PLL

- the degree of collapse; > 50% collapse are generally considered unstable

117
Q

Thoracolumbar Fractures

A
  • T1 - T9: rare d/t increased stability from ribs
  • Above T10: cord transection
  • T10 - L1: cord and nerve root lesion combination
  • Below L1: nerve root injury/lesion only
118
Q

Chance Fracture

A

vertebrae fracture that transects the cord and all abdominal organs; patients often expire from internal bleeding

119
Q

Lamina Fracture

A
  • usually from a missile or fracture
  • neural damage possible
  • no articular problems
  • function (no loss of motion)
120
Q

Pedicle Fracture

A

movement may lead to paraplegia

121
Q

Transverse/Spinous Process Fracture

A

direct blow, but usually have a quick recovery

122
Q

When is myelography indicated?

A
  • confirm or exclude intraspinal lesions
  • establish the size and location of a known lesion
  • medicolegal reasons
123
Q

Abnormal myelographic results

A
  • ruptures of IV disc
  • spinal cord compression
  • stenosis
  • tumor
  • nerve root injury
