Lecture 4: Sacral SD Flashcards

1
Q

Lateralization tests will tell you what about the axis of a torsion and unilaterally?

A
  • Positive test is opposite of the side of axis for a torsion
  • Positive test is on the same side for unilaterals

Q

How can you tell if a sacrum is unilaterally flexed vs. extended?

A
  • If deep sacral sulcus is on the right, posterior/caudad ILA on the right, lateralization test was on the right, sphinx test and/or lumbar spring is negative = right unilateral flexed sacrum
  • If deep sacral suclus is on the right, posterior/caudad ILA on the right, lateralization test is to the left, sphinx test and or/ lumbar spring test is positive = left unilateral extended sacrum

Q

What is a compensated L5?

A

If L5 is rotated in the opposite direction of the sacrum, is said to be compensated

Q

Forward torsions (L/L ST or R/R ST) are considered flexed and in this regard which type of mechanics does L5 follow?

A
  • Type I mechanics
  • A flexed sacrum means a neutral L5

Q

Bacward torsions (L/R ST or R/L ST) are considered extended and what type of mechanics will L5 follow?

A
  • Type 2 mechanics
  • Extended sacrum = non-neutral L5 (Type 2)

Q

If you have the sulci and ILA findings, but no seated flexion findings, how do you know the type of torsion?

A

Use the BBT or LS

17
Q

How does an uncompensated L5 affect our treatment?

A

You should treat L5 before the sacral dysfunction
