Sacrum Diagnosis (extra Dr. Chou) Flashcards
What is sacral sulcus? terminology to describe it?
Distance btw PSIS and sacral base
- “deep” or “shallow”
Terminology to describe sacral base?
- Anterior and posterior
- If SS is deep= SB is anterior
- If SS is shallow = SB is posterior
ILA?
- found as superior/anterior
- or inferior/posterior
What are the two possible SS and ILA diagnosis for Unilateral dysfxn?
- SS: Ant
- ILA: Post
- they have to stick with a seesaw motion
What are the two possiby SS and ILA diagnoses for a torsion>
- (on same side)SS: ant
- ILA: ant
- R on L
or
- SS: post
- ILA: post
- R on R
What does SFT tell you?
Right or left sacral base part of the SD
Lumbosacral spring?
- Passive test to see if the sacral base can flex
- resists: positive (sacral base relevant to SD is posterior/extended)
- motioni: negative (sacral base is anterior/flexed)
Backward bend test?
- Active test to see if the sacral base can flex
- start uneven → lumbar extension → sacral flexion
- if it stays uneven or gets more uneven its positive and sacral base is posterior/extended
- If it becomes more even then the test is negative and it is anterior/flexed
Respiratory motion test?
- inhalation=extended sacrum
- exhalation = flexed sacrum
Describe all extension sacrum diagnoses?
- b/l ext
- u/l ext
- backwards torsions
- R on L
- L on R
Describe all possible flexion sacral diagnoses?
- b/l flex
- u/l flex
- Forward torsion
- R on R
- L on L
Right SS is shallow and L ILA is inferior. SFT is + on the right. What is diagnosis? What should other motion tests be?
- Right Unilateral extension
- LSS → resists = +
- BBT → more uneven = +
- Resp= inhalation
R SS is shallow, left Inferior ILA. Lumbosacral spring test resists motion. What is the SD and other motion tests?
- R unilateral extension
- LSS resists motion so it is positive meaning its extended
- BBT will be uneven, so positive
- Resp. will prefer inhalation
- knowing that its extended you have to figure out which side fits that to get the SFT results
BBT becomes even on testing. Right sacral sulcus is shallow and the left ILA is inferior. What is the SD and what will the othe motion testss show?
- LUF
- LSS = -
- BBT= -
- resp. exhalation
- SFT= Left +
Left SS is deep, Right ILA is inf/post. Diagnosis and other motion test results? LSS test is negative.
- SFT= + on left
- LSS= -
- BBT= -
- Resp. = exhalation
- R on R torsion
look for which is posterior, that will tell you the rotation. If it is posterior on right it is rotated right and if on left rotated left.
- L SS= deep
- R ILA= posterior
- Resp. = inhalation
What is diagnosis and other motion test results?
- Resp= extended
- LSS= resists flexion so +
- BBT= (same as LSS) so +
- SFT= + on right, need to figure out which side fits posterior for extension
- R on L torsion
- Left sacral base is posterior
- Left ILA is inferior
- BBT becomes more even
all posterior’s are on the left side, so you know that this will be left rotation. We have to keep seesaw motion so this can ONLY be a torsion bc Anterior’s are on the same side and posterior’s are on the same side.
- BBT= negative so prefers flexion
- LSS = negative, prefers flexion
- Resp. = exhale
- SFT = + on right
- L rotation on a L oblique axis
Patient has LBP and tart around the sacrum. SS are even and ILA’s are also even. The LSS resists motion, what is the diagnosis and what do other motion tests show?
- SFT is false negative as both move up
- BBT you start even and stay even, so false negative
- Best tests to do for this are:
- LSS resists motion so it is positive meaning it is extended
- Respiration will prefer inhalation because it likes extension
- Bilateral Extension
Patient has LBP and tart findings along the sacrum. The SS and ILA’s are even. The Respiratory motion test reveals it prefers exhalation. What is the diagnosis and what do other motion tests show?
- LSS will be negative so it moves easily into flexion
- BBT will start even and move even so it is a false negative
- SFT will be false negative as both PSIS move superiorly
- B/L flexion
