Flashcards in Abnormal Curvatures of the Spinal Column Deck (24):
1

Does "osis" infer a normal or an abnormal condition?

Neither, it is non-judgmental

2

What names are given to conditions associated with abnormal curves of the vertebral column?

- lordosis
- kyphosis
- scoliosis

3

What is the definition of lordosis?

A forward bending condition

4

What is the definition of kyphosis?

A humpback or hunchback condition

5

What is the definition of scoliosis?

A warped or crooked condition

6

What is the direction of the curve deviation in lordosis?

To the anterior

7

What is the direction of the curve deviation in kyphosis?

To the posterior

8

What is the direction of the curve deviation in scoliosis?

To the side (it is a lateral deviation)

9

Is there a locational bias for the classic definition of lordosis?

No, there would be:
- an increase in the anterior direction in the cervical spine
- a decrease in the posterior direction in the thoracic spine
- an increase in the anterior direction in the lumbar spine
- a decrease in the posterior direction in the pelvic or sacrococcygeal region

10

Is there a locational bias for the classic definition of kyphosis?

No, there would be:
- a decrease in the anterior direction in the cervical spine
- an increase in the posterior direction in the thoracic spine
- a decrease in the anterior direction in the lumbar spine
- an increase in the posterior direction in the pelvic or sacrococcygeal region

11

What clinical examples of abnormal curvatures along the vertebral column were stressed in class?

- military neck
- humpback or hunchback
- swayback

12

What is military neck?

- A decreased anterior curve in the cervical region, a straight neck
- example of kyphosis

13

What is humpback or hunchback?

- An increased posterior curve in the thoracic region
- example of kyphosis

14

What is swayback?

- An increased anterior curve in the lumbar region
- example of lordosis

15

What does the use of the term lordotic try to imply?

A normal cervical and normal lumbar anterior curve

16

What does the use of the term kyphotic try to imply?

A normal thoracic/dorsal and normal pelvic/sacrococcygeal posterior curve

17

What prefixes are used to convey abnormality in curve patterns

hyper and hypo

18

What does the term hyperlordotic infer?

an increase in the anterior curve of the cervical or lumbar region

19

What does the term hypolordotic infer?

a decrease in the anterior curve of the cervical or lumbar region

20

What does the term hyperkyphotic infer?

an increase in the posterior curve of the thoracic/dorsal or pelvic/sacrococcygeal region

21

What does the term hypokyphotic infer?

a decrease in the posterior curve of the thoracic/dorsal or pelvic/sacrococcygeal region

22

What is the more complete, accepted definition of scoliosis?

an abnormal lateral curve coupled with axial rotation

23

What is the relationship between degrees of lateral curve deviation, axial rotation, and care?

- curves with 10-20 degrees of lateral deviation and a fixed angle of trunk rotation have scoliosis
- curves with 20-30 degrees of lateral deviation and a fixed angle of trunk rotation of 5 degrees require attention
- curves with 30-50 degrees of lateral deviation and a fixed trunk rotation of 7 degrees require intervention as they have a 60% chance to worsen
- curves with greater than 50 degrees of lateral deviation have a 90% chance to worsen

24

What is the radiological test for skeletal maturity?

- the Risser sign
- an indication of bone maturity in the iliac apophysis
