Anterior sacroiliac ligament
Ligament of the pelvis
The anterior sacroiliac ligament is a ligament of the pelvis that connects the sacrum to the ilium on the anterior (front) side of the sacroiliac joint. This ligament plays a crucial role in stabilizing the sacroiliac joint and supporting the weight transfer between the upper body and the lower limbs.
Anatomy[edit | edit source]
The anterior sacroiliac ligament is a broad, flat band of connective tissue. It originates from the anterior surface of the sacrum and extends laterally to attach to the anterior part of the ilium. The ligament is relatively thin compared to the posterior sacroiliac ligament, but it is essential for maintaining the integrity of the sacroiliac joint.
Function[edit | edit source]
The primary function of the anterior sacroiliac ligament is to provide stability to the sacroiliac joint. It helps to prevent excessive movement between the sacrum and the ilium, which is crucial for maintaining proper alignment and function of the pelvis. This ligament also assists in the distribution of forces from the upper body to the lower limbs during activities such as walking, running, and lifting.
Clinical Significance[edit | edit source]
Injuries or dysfunctions of the anterior sacroiliac ligament can lead to sacroiliac joint dysfunction, which may cause pain in the lower back, buttocks, and legs. Conditions such as sacroiliitis and sacroiliac joint syndrome are often associated with inflammation or damage to this ligament. Treatment for issues related to the anterior sacroiliac ligament may include physical therapy, medication, or in severe cases, surgical intervention.
