Sacrum Diagnosis Mary Goldman 11/2008
Basic background facts • The standing flexion test reflects both sacrum and pelvis, but the seated flexion test reflects just the sacrum • Prominent sacral base is the more posterior, but a deep sacral base may be the cause of a prominent sacral base on the other side (so the prominent side is not protuberant in this case) • The prominent ILA is also the lower ILA
Types of sacral somatic dysfunction • Bilateral flexion/extension (normal seated flexion test) • Sacral Torsion • Unilateral sacrum • Marginal sacrum is not tested on boards and is a rare finding
Flexion tests • If standing is positive on the same side as the seated, the sacrum may be the only abnormal, so treat sacrum and recheck • If standing is positive on the opposite side of the seated test, treat pelvis and then sacrum • Some schools treat the pubes or the lumbar spine first
Diagnosing sacral torsion vs unilateral sacrum • All torsions have an oblique axis, but the sacral base and ILA prominents are on the SAME side • All unilateral have a transverse axis, but the prominents are on opposite corners
Picture that! Prominent sacral base & ILA do not follow pattern of axis TORSION UNILATERAL SAME SIDE OPPOSITE CORNERS
Treatment plan lay on side of axis lay prone Treat leg turned in Treat leg turned out Treat face down if feet off table Treat face up if feet off table
