LIGAMENTUM SACROSPINOSUM Meaning and
Definition
-
The ligamentum sacrospinosum is an anatomical structure found in the human body. It is a dense, fibrous band that connects two specific bones in the pelvic region, namely the sacrum and the ischial spine. This ligament is situated within the greater sciatic foramen, which is a large opening in the pelvic bone.
The ligamentum sacrospinosum is located in the deep region of the pelvic floor, running diagonally between the sacrum, a triangular bone located at the base of the spine, and the ischial spine, a prominent bony projection on the pelvic bone. It passes beneath the gluteus maximus muscle, one of the major muscles of the buttocks.
This ligament plays a vital role in providing stability and support to the pelvic region. It functions to limit excessive movement of the sacrum, specifically preventing excessive rotation. Additionally, the ligamentum sacrospinosum helps to secure and stabilize other structures within the pelvis, such as blood vessels and nerves.
The ligamentum sacrospinosum is composed of dense fibrous connective tissue, which is strong and resistant to stretching. This structural strength allows it to efficiently transmit forces between the sacrum and the ischial spine, preventing excessive mobility and maintaining the overall stability of the pelvis.

Etymology of LIGAMENTUM SACROSPINOSUM
The word "ligamentum sacrospinosum" has Latin roots.
- "Ligamentum" in Latin means "a band" or "a tie". In anatomy, it refers to a fibrous band or sheet of connective tissue that connects bones or holds organs together.
- "Sacro" indicates the sacrum, which is a triangular bone at the base of the spine.
- "Spinosum" refers to the spine.
Therefore, when combined, "ligamentum sacrospinosum" signifies a ligament or band that connects the sacrum to the spine.
