So im reviewing for my OPP final and Im trying to remember what is absolutely needed to diagnose the sacrum. I thought you needed 3 things minimum: spring test (sphinx), ILA position, and sulcus position. Our sacrum exam had many cases with 3 pieces of info and the answer some of the time was not enough information so im wondering again what info you absolutely need as I cannot find it in DiGiovanna. thanks
So you need a seated flexion test to confirm whether or not there is a sacral dysfunction
After you have a position seated flexion test (doesn't matter which side it's on) you do the sulcus. This will give your first name. I think of it as the way that the sacrum is facing.
Then do the ILAs. The side that is posterior/inferior is the one you care about. If it's on the same side as your deep sulcus --> it's either a flexion or extension
If it's on opposite side as your deep sulcus ---> torsion
Now do you sphinx test. How I remember this is that a positive sphinx fukes everything up. (I'll explain more in a bit)
So if you have you a positive sphinx test and you had a torsion - that means that it's going to be backward torsion (which is a fuk up because it's worse for pt, and also more complicated to treat) It also changes the second name. So you found the first name from the deep sulcus (the way the sacrum is facing), the second name is going to be the
opposite that of the first name. So what would a right deep sulcus, left inferior/posterior ILA, and positive sphinx be? (answer in white)
left on right backward sacral torsion
Things are more simple with a negative sphinx test, so that would give you a forward torsion (again assuming that your deep sulcus and posterior/inferior ILA are on opposite sides) So what would a left deep sulcus, right inferior/posterior ILA, and negative sphinx be?
right on right forward sacral torsio
Now on to flexions/extensions. Again, note that extensions are worse (as in for the pt and the treatment is more complex) and your name gets switched with a positive sphinx test. Note that you only have one name this time because the ILA and sulcus are on the same side
So you have a deep sulcus on left, posterior/inferior ILA on left, and a positive sphinx test, what is that? right unnilateral extension
n
You have a deep sulcus on the right, posterior/inferior ILA on the right, and a negative sphinx test, what is that?
right unilateral flexion
So just remember - positive sphinx test fuks everything up.
