From the Research
The muscles that attach to the Anterior Superior Iliac Spine (ASIS) are the sartorius, tensor fasciae latae, and part of the gluteus medius, as evidenced by a study on triple muscle pedicle bone grafting in neglected femoral neck fracture patients 1.
Muscle Attachments to ASIS
The sartorius muscle originates at the ASIS and inserts at the medial surface of the proximal tibia, functioning to flex, abduct, and laterally rotate the hip, as well as flex the knee.
- The tensor fasciae latae also originates at the ASIS and inserts into the iliotibial band, which attaches to the lateral condyle of the tibia, assisting with hip flexion, abduction, and medial rotation.
- Part of the gluteus medius muscle is also attached to the ASIS, as seen in the context of muscle pedicle bone grafting procedures 1.
Clinical Significance
These muscle attachments are important for various movements of the lower limb, including walking, running, and maintaining posture.
- The ASIS serves as a key anatomical landmark for these muscle attachments and is easily palpable at the front of the pelvis, making it clinically significant for physical examinations and as a reference point for various medical procedures.
- Understanding the anatomy of the ASIS and its associated muscles is crucial for diagnosing and treating conditions affecting the hip and lower limb, such as femoral neck fractures, which can benefit from procedures like triple muscle pedicle bone grafting 1.
