Anterior Superior Iliac Spine
Anterior Superior Iliac Spine
The Anterior Superior Iliac Spine (pronounced: an-TEER-ee-or soo-PEER-ee-or IL-ee-ak SPINE), often abbreviated as ASIS, is a bony projection of the Ilium and an important anatomical landmark in the human skeletal system.
Etymology
The term "Anterior Superior Iliac Spine" is derived from the Latin words 'anterior' meaning 'front', 'superior' meaning 'above', 'iliac' referring to the 'hip bone', and 'spine' referring to the 'sharp projection'.
Anatomy
The ASIS is the anterior end of the iliac crest and provides attachment for the inguinal ligament, and the sartorius muscle. It is easily palpable in the living body, and it helps to define the Scarpa's triangle.
Clinical significance
The ASIS is used as a landmark in various surgical procedures and in the diagnosis of certain conditions. For example, a difference in the level of the ASISs may indicate a hip dislocation.
