1

A vertebra that takes on characteristics on both sides of a major division of the spine

Transitional Vertebra

2

A transitional vertebra of C7-T1 is what?

An extra rib

3

A transitional vertebra of T12-L1 is what?

rib articulating with transverse process

4

A transitional vertebra of L5-S1 is what?

Expanded transverse process (unilateral or bilateral)

5

Posterior defect of the spinal canal-failure to close properly

Spina Bifida

6

A mild form of spina bifida in which there is a splitting of the bony neural canal at the L5-S1 level

Spina Bifida Occulta

7

Large defects are associated with spinal cord abnormalities & lead to what?

Muscular abnormalities and lack of bladder or bowel control.

8

Slight ________ of skin or tuft of _______ over the site of lesion/defect in Spina Bifida

dimpling/ hair

9

Herniation of meninges from large defects in the lumbar or cervical spine

Meningocele

10

Herniation of meninges & portion of spinal cord or nerve roots

Myelomeningocele

11

What is the appearance of spina bifida

1. Large bony defects, absence of laminae & increased interpedicular distance
2, Soft tissue mass posterior to spine

12

Another name for Marble Bone Disease

Osteopetrosis

13

A rare hereditary bone dysplasia in which failure of the resorptive mechanism of calcified cartilage interferes with the normal replacement by mature bone. Prevents bone marrow from forming (brittle bone-stress fx)

Osteopetrosis

14

With Osteopetrosis, what do you need to do for technique

increase in technique due to generalized increase in bone density.

15

Brittle Bone Disease

Osteogenesis Imperfecta

16

Disorder of connective tissue with severe osteoporosis. Thin, defective cortices (low kvp). Its Characterized by multiple fractures (exuberant callus formation, bizarre deformaties).

Osteogenesis Imperfecta

17

What disease of the bone sometimes may be confused with Child Abuse because of the presentation of multiple fractures in different stages of the healing process?

Osteogenesis Imperfecta

18

Diminished proliferation of cartilage in the growth plate-Most common form of dwarfism

Achondroplasia

19

What is the appearance of Achondroplasia?

1. Progressive narrowing of interpedicular distance from superior to inferior (opposite of normal).
2. Scalloping of posterior margins of lumbar vertebral bodies.
3. Long bones appear short & thick

20

Acetabulum does not completely form causing head of femur to become displaced superiorly and posteriorly. Ligaments & tendons / unilateral or bilateral. Mostly occurs in females

Congenital Hip Dysplasia

21

What views are needed to demonstrate congenital hip dysplasia?

AP and bilateral frog leg (cleaves)

22

Chronic systemic disease of unknown cause. Inflammation and overgrowth of synovial tissue. Periarticular soft tissue swelling, symmetric joint destruction & deformity.

Rheumatoid Arthritis

23

In Rheumatoid Arthritis where is it most commonly found and in whom?

Small bones of hands and feet (crippling deformity).
Females/ avg age is 40 years

24

How does Rheumatoid Arthritis begin?

As an inflammation of the synovial membrane that lines the joints.

25

Excessive exudate (fluid) causes what in Rheumatoid Arthritis?

proliferation of synovium

26

Rheumatoid Arthritis results in what?

a mass that causes erosion of articular cartilage and underlying cortex (development of ankylosis-bone fusion across joint).

27

In Rheumatoid Arthritis the destruction of cartilage causes what?

narrowing of joint space

28

Ulnar deviation in the hands is common in what disease?

Rheumatoid Arthritis

29

Progressive form of arthritis involving the spine and SI joints.

Ankylosing Spondylitis

30

To whom does Ankylosing Spondylitis often occur in?

Males 20-40 years of age
