The anterior superior iliac spine ( ASIS) is a bony projection of the iliac bone, and an important landmark of surface anatomy. It refers to the anterior extremity of the iliac crest of the pelvis. It provides attachment for the inguinal ligament, and the sartorius muscle. [1] The anterior superior iliac spine is an important bony surface landmark and is the prominence is the most anterior part of the ilium. It can be palpated at the lateral end of the inguinal fold. Attachments include the inguinal ligament , sartorius muscle and depending on which resource you read, the tensor fasciae latae.
Iliac crest pain Causes, exercises, and treatment
The anterior superior iliac spine (ASIS) is the blunt process that marks the anterior end of the iliac crest. It is subcutaneous and can be palpated at the lateral end of the inguinal fold. Spina iliaca anterior superior Definition The anterior superior iliac spine is a notable bony protuberance located at the junction of the superior margin (iliac crest) and the anterior margin of the ilium. The anterior superior iliac spine serves as an attachment point for significant structures such as the inguinal ligament and sartorius muscle. An anterior superior iliac spine (ASIS) avulsion is a traumatic avulsion of the ASIS due to a sudden and forceful contraction of the sartorius and tensor fascia lata that occurs in young athletes. Diagnosis is made radiographically with displaced injuries but CT/MRI may be required to diagnosis nondisplaced fractures. Structure. The Anterior superior iliac spine is formed by the union of the ilium and the pubis bones, which make up the pelvis. It is a small, triangular-shaped bone that protrudes from the front of the pelvis and can be easily felt through the skin. It is located on either side of the midline of the body, just below the waist.

Anterior superior iliac spine (ASIS) avulsion injuries typically occur in athletes during forceful muscular contraction. The anterior superior iliac spine is the site of attachment for sartorius and tensor fascia latae muscles . Pathology Anterior superior iliac spine avulsion, like other pelvic avulsion injuries, is a stable fracture. The iliac crest is the superior margin of the ilium. It forms a curved ridge line of bone that can be palpated when you 'put your hands on your hips'. This bony crest provides attachments for a number of muscles, ligaments and fascia. Including the lateral abdominal muscles ( external abdominal oblique muscle, internal abdominal oblique. The anterior superior iliac spine, which develops from an anterior apophysis of the iliac crest, is the site of origin of the sartorius muscle and part of the tensor fasciae latae. The iliac crest is the most prominent part of the ilium, the largest of the three bones that make up the bony pelvis or hip bone. Pain can occur due to wear, tear, trauma, and exercise. Exercises.

The iliacus muscle belongs the group of the inner hip muscles, together with the psoas major, psoas minor, obturator externus, obturator internus, superior gemellus, inferior gemellus, piriformis, and quadratus femoris muscles. As a group, the inner hip muscles act upon the hip joint. Gender: Male. mri. Oblique T2. fat sat. Coronal T2. fat sat. Axial T2. fat sat. Bone marrow and surrounding soft tissue edema at the anterior superior iliac spine involving the sartorius muscle origin without separation as may occur in an acute avulsion injury.
Anterior superior iliac spine Spina iliaca anterior superior 1/3 Synonyms: ASIS The sartorius muscle originates by a round tendon from the anterior superior iliac spine and the upper half of the notch between the anterior superior iliac spine and the anterior inferior iliac spine. Introduction Manual palpation is commonly used for the assessment of patients with neuromusculoskeletal dysfunction [1]. Many pelvic landmarks are easily palpable on physical exam eg the iliac crest, the anterior superior iliac spine (ASIS), posterior superior iliac spine (PSIS).
Anterior Superior Iliac Spine Muscle Attachment
The anatomical landmarks that are commonly located and contacted to perform these tests include the anterior superior iliac spine (ASIS), the posterior superior iliac spine (PSIS), the iliac crest, the sacral sulcus, the sacral apex, and the inferior lateral angle of the sacrum (SILA).
