    thicker
  33. 33The upper (superior) zygapophyseal joints form an angle of ____ degrees to the MSP50
  34. 34The lower (inferior) zygapophyseal joints form an angle of ____ degrees to the MSP30
  35. 35Compression Fxsuperior and inferior surfaces of vertebral bodies are driven together
  36. 36HNP Herniated Nucleus Pulposus"slipped disk"
    -nucleus pulposus protrudes through the fibrous outer later and presses on spinal nerves and cord
    -causes sciatica
    -evaluated by CT and MRI
  37. 37Spina Bifidacongenital condition where the lamina fail to unite leaving a portion of the spinal cord exposed
  38. 38What should you use to reduce scatter for a lumbar spine exam?lead mat on table top
  39. 39Why do you flex the patient's knees for the AP lumbar spine projection?straightens the spine and opens the intervertebral disk spaces
  40. 40How can you tell if the patient was rotated on an AP lumbar spine radiograph?SI joints should be equal distance from the spine
  41. 41If patient is obliqued to the left on an AP lumbar radiograph, what will it look like?The left SI joint will appear shifted and larger as well as the left sacral ALA
  42. 42AP lumbar radiograph reveals SI joints are not equidistant from the spine, the right ALA of the sacrum appears larger, and the left SI joint is more open than the right. What was the positioning error?Patient is rotated to the RIGHT
  43. 43Which lumbar oblique will best demonstrate T12-L1?50 degree oblique
  44. 44Which lumbar oblique will best demonstrate L5-S1?30 degree oblique
  45. 45If you're looking for pathology on the lower lumbar, and don't see the lower lumbar Scottie Dog on a30 degree oblique, what was the positioning error?Too much obliquity
  46. 46If the joint spaces on the left Lateral Lumbar radiograph are not open, what was the positioning error?Patient's spine is curved laterally, probably from not having a support under the lower abdomen
  47. 47Which lumbar spine projection best demonstrates a compression Fx?Lateral Lumbar
  48. 48Which photocell would you use for a Lateral Lumbar projection?Center
  49. 49Where is your CR centered for the Lateral L5-S1 Spot?perpendicular @ 1.5 in inferior to iliac crest, and 2 in. posterior to ASIS
    *make a C around the iliac crest with your fingers, center between the tips of your fingers*
  50. 50How is the CR angled for the Axial Lateral L5-S1 spot?CR angled 5-8 degrees caudal
    angle more if pt is asthenic
    angle less for female
  51. 51What are the routine views for a scoliosis series?AP or PA Erect
    Erect Lateral
  52. 52Why do scoliosis series need to be done PA instead of AP?PA will reduce the radiation dose to breasts and thyroid by 90%
  53. 53TRUE OR FALSE bladder must be empty before starting sacrum/coccyx exam?TRUE
  54. 54_____ and ____ will best visualize the left zygapophyseal jointLPO
    RAO
  55. 55___ and ___ will best visualize the right zygapophyseal jointRPO
    LAO
  56. 56Which projection will best visualize a compression Fx?Lateral Lumbar
  57. 57HNP, also known as _________ , occurs most commonly at the level of ___ and causes sciaticaherniated nucleus pulposus
    L4-L5
  58. 58This is a congenital condition in which the posterior aspects of the vertebrae fail to develop, this exposes part of the spinal cordSpina Bifida
  59. 59the forward movement of one vertebra into another, most common at L5-S1Spondylolisthesis
  60. 60separation of the pars interarticularis of the vertebra that results in dissolution of vertebrae *scottie dog's neck appears brokenSpondylosis
  61. 61The zygapophyseal joint is classified as _____ and ____ meaning it has a gliding type of movement.synovial
    diarthrodial
  62. 62The intervertebral joint is classified as _____ and _____ meaning it has little to no movement.cartilaginous
    amphiarthrodial
  63. 63Why do we angle cephalic for the sacrum?place the sacrum parallel to IR
  64. 64Why do we angle caudal for the coccyx?place the coccyx parallel to the IR
  65. 65For the posterior oblique SI joints, which side will you see best in the RPO position? LPO position?RPO = left side up
    LPO = right side up
  66. 66If the ilium is superimposed over the SI joint for the posterior oblique projection, what was the positioning error?patient was obliqued too much
  67. 67How can you tell if a patient is underrotated for the oblique lumbar?zygapophyseal joints will be too anterior
    spinous processes will be more centered
  68. 68How can you tell if a patient was overrotated for the oblique lumbar?zygapophyseal joints will be more posterior
    spinous processes will be more lateral
  69. 69What anatomy is best visualized on the oblique lumbar spine?zygapophyseal joints
    pars interarticularis
