ASIS, in medical terms, stands for anterior superior iliac spine. It is a palpable bony landmark on the front of the pelvis, easily located on each side of the body. The anterior superior iliac spine is an important reference point for medical professionals.
Significance of the ASIS
The ASIS serves as a crucial anatomical landmark for various reasons:
- Radiographic Palpation Point: As the reference mentions, the ASIS is a key radiographic palpation point on the skin on each side of the front of the pelvis.
- Muscle Attachment: Several muscles attach to or originate near the ASIS, including the sartorius and tensor fasciae latae.
- Pelvic Alignment Assessment: Healthcare providers use the ASIS to assess pelvic alignment and identify potential postural imbalances.
- Surgical Procedures: It serves as a reference point during surgical procedures involving the pelvis and hip.
- Measurements: The ASIS is used as a point of origin for taking measurements of the lower extremity, such as leg length.
Locating the ASIS
Finding the ASIS is a relatively simple process:
- Place your hands on your hips.
- Move your fingers forward and downward.
- You will feel a bony prominence on each side of the front of your pelvis. This is the ASIS.
