The anterior superior iliac spine refers to the anterior extremity of the iliac crest of the pelvis. This is a key surface landmark, and easily palpated. It provides attachment for the inguinal ligament, the sartorius muscle, and the tensor fasciae latae muscle.
What structure inserts on the anterior inferior iliac spine?
The anterior inferior iliac spine (AIIS) is bony prominence on the anterior border of the ilium forming the superior border of the acetabulum. Attachments include the Iliacus, origin of straight head of the rectus femoris, and also the proximal ileofemoral ligament (Y-ligament or ligament of Bigelow).
What inserts on iliac crest?
Muscles that insert onto the ilium: quadratus lumborum muscle at the iliac crest and onto the iliolumbar ligament. external oblique, internal oblique and transversus abdominis muscles of the abdominal musculature as well as latissimus dorsi muscle insert at the iliac crest.
What attached to ASIS?
The ASIS is the attachment of the sartorius, a thigh muscle that is important in bending the hip and knee. Avulsion fracture of the ASIS is caused by a powerful con- traction of the sartorius muscle, such as with jumping and running sports, with force exceeding the strength of the growth plate.
What originates from anterior inferior iliac spine?
1. Rectus femoris originates from around the anterior inferior iliac spine of the pelvis and inserts into the quadriceps tendon; it flexes the hip, as well as being part of the quadriceps, a group of four muscles which extend the knee.
Why is the anterior inferior iliac spine an important feature?
Function. The upper portion of the spine gives origin to the straight head of the rectus femoris muscle. A teardrop-shaped lower portion gives origin to the iliofemoral ligament of the hip joint and borders the rim of the acetabulum.
What does iliac crest pain feel like?
What iliac crest pain feels like. The most common type of iliac crest pain is associated with chronic low back pain. You may also have tenderness around the iliac crest, with can feel like hip or pelvic pain. Iliac crest pain can increase with movement.
Why would my iliac crest hurt?
The iliac crest can be damaged because of a traumatic experience such as a car accident or a bad fall, causing you to feel pain in your hip area or lower back. Weak muscles. Strong core muscles help your joints move with ease. But if your abdominal muscles or lower back muscles are weak, hip pain can occur.
Why is iliac crest important?
The iliac crest provides attachment for the hip flexors, the abdominal muscles, and the muscles that rotate the hip. Direct impact on the iliac crest can cause contusion, bruising, and inflammation of tissue or even bone fracture.
What is Asis Apophysitis?
Repeated movement and stress to the muscles attached to the bone can inflame and irritate the muscles. This can cause inflammation at the point where the tendon (soft tissue) attaches to the bone. It can cause pain, swelling and tenderness in the hip area, resulting in an injury known as hip apophysitis.
How do you identify anterior superior iliac spine?
Anterior superior iliac spine (ASIS) ➢ Put your hand on the hips ➢ locate the Iliac Crest / hip bone palpate frontward ➢ ASIS is a sharp notch:, above the femur/ thigh bone when seated. ➢ Sit on your hand with palm up to feel the IT against your fingers tips.
What is anterior inferior iliac spine decompression?
Low AIIS decompression is a safe, effective, and reproducible procedure for addressing subspinal impingement. Creating a flat anterior acetabular surface between the most anteroinferior prominent point of the AIIS and the acetabular rim allows flexion and internal rotation of the hip joint without impingement.
What is an anterior inferior iliac spine?
The anterior inferior iliac spine (AIIS) apophysis is a bony prominence, from which the direct head of the rectus femoris and the ilio-capsularis muscles originate and is situated superior and antero-medial to the most lateral point on the acetabular rim.
