1

Apical Vertebra

Most rotated and laterally placed vertebra within a curve

2

Double Major Curve

Two structural curves that are within 10 degrees of each other

3

Menarche

Beginning of the menstrual cycle
usually around 12-13 years of age

4

Major curve

Largest curve; usually the most vertebral rotation

5

Minor Curve

Smaller curve; usually has the least degree of vertebral rotation
Evaluate to analyze if the curve is compensatory

6

Peak height velocity

Growth rate of at least 9cm/year
calculated by standing height measurements of 6 month intervals for a minimum of 2 1/2 years

7

Risser Sign

Indication of skeletal maturity; 5 grades

8

Tanner Sign

Development of secondary sexual characteristics; 5 stages
Examples, growth of breast tissue in females and "voice change" in males

9

Scoliosis

Lateral curvature of the spine greater than 10 degrees

10

Non-structural curve

Rotary component will correct upon lateral flexion

11

Structural Curve

Rigid rotary component; will not connect during lateral flexion

12

Compensatory Curve

Curve that develops secondary to a primary curve to maintian body alignment

13

Null point

Location where the vertebral inclination changes direction
