Description[edit | edit source]
Anterior sacroiliac ligament (ASL) is comprised of many thin strands and forms from a thickened part of the anterior joint capsule[1][2] . It is a smooth sheet of dense connective tissue stretching between the ventral surfaces of the sacral alar and ilium[1]. It is the thinnest sacroiliac joint ligament[2] and is larger in males[1].
Attachments[edit | edit source]
It runs from the iliac ala, anterior to the auricular surface, to the sacrum's pelvic surface[3].
Function[edit | edit source]
Limiting sacral nutation.
Clinical relevance[edit | edit source]
It is associated with sacroiliitis
It is located close to the trunk of the lumbosacral plexus(especially fibers from L4–L5) and to the obturator nerve.
Leakage of fluid to the surrounding structures at the site of the anterior capsule may happen because it is a relatively thin capsule[1].
Assessment[edit | edit source]
There are various provocation tests for the sacroiliac joint but none of them isolate the anterior sacroiliac joint ligament.
