Fryette's Principles Flashcards
In what direction do the superior facets face in the cervical spine?
Backwards, Upward, and Medial (BUM)
In what direction do the superior facets face in the thoracic spine?
Backwards, Upward, and Lateral (BUL)
In what direction do the superior facets face in the lumbar spine?
Backwards and Medial (BM)
What is vertebral rotation named in reference to?
The anterior body. Imagine looking down on a vertebrae from overhead.
What rule of 3’s pattern does T10 follow?
T10 follows the same rules as T7-T9 (spinous process is one full segment below the transverse)
What rule of 3’s pattern does T11 follow?
T11 follows the same rules as T4-T6 (spinous one half segment below the transverse)
What rule of 3’s pattern does T12 follow?
T12 follows the same rules as T1`-T3 (spinous process is at the same level as the transverse)
Who is credited with discovering Fryette’s Principles?
Harrison Fryette, DO
Who is credited with adding the third of Fryette’s Principles?
C.R. Nelson, DO
To what spinal regions do the first and second Fryette principles apply?
The first and second only deal with the thoracic and lumbar spine.
To what spinal regions does the third Fryette principle apply?
The third applies to the cervical, thoracic, and lumbar spine.
What is the first principle?
When the spine is in neutral, sidebending to one side will be accompanied by horizontal rotation to the opposite side.
What is the second principle?
When the spine is flexed or extended, sidebending to one side will be accompanied by rotation to the same side.
What is the third principle?
Initiating movement of a vertebral segment in any plane of motion will modify the movement of that segment in other planes of motion.
What comes first when naming vertebral somatic dysfunctions?
The vertebral segment (i.e. T7)
