1
Q

Does “osis” infer a normal or an abnormal condition?

A

Neither, it is non-judgmental

2
Q

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

A
  • lordosis
  • kyphosis
  • scoliosis
3
Q

What is the definition of lordosis?

A

A forward bending condition

4
Q

What is the definition of kyphosis?

A

A humpback or hunchback condition

5
Q

What is the definition of scoliosis?

A

A warped or crooked condition

6
Q

What is the direction of the curve deviation in lordosis?

A

To the anterior

7
Q

What is the direction of the curve deviation in kyphosis?

A

To the posterior

8
Q

What is the direction of the curve deviation in scoliosis?

A

To the side (it is a lateral deviation)

9
Q

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

A

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
Q

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

A

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
Q

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

A
  • military neck
  • humpback or hunchback
  • swayback
12
Q

What is military neck?

A
  • A decreased anterior curve in the cervical region, a straight neck
  • example of kyphosis
13
Q

What is humpback or hunchback?

A
  • An increased posterior curve in the thoracic region

- example of kyphosis

14
Q

What is swayback?

A
  • An increased anterior curve in the lumbar region

- example of lordosis

15
Q

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

A

A normal cervical and normal lumbar anterior curve

16
Q

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

A

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

17
Q

What prefixes are used to convey abnormality in curve patterns

A

hyper and hypo

18
Q

What does the term hyperlordotic infer?

A

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

19
Q

What does the term hypolordotic infer?

A

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

20
Q

What does the term hyperkyphotic infer?

A

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

21
Q

What does the term hypokyphotic infer?

A

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

22
Q

What is the more complete, accepted definition of scoliosis?

A

an abnormal lateral curve coupled with axial rotation

23
Q

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

A
  • 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
Q

What is the radiological test for skeletal maturity?

A
  • the Risser sign

- an indication of bone maturity in the iliac apophysis
