LATERAL MASSES OF THE SACRUM Meaning and Definition

1. The lateral masses of the sacrum refer to the prominent bony structures located on both sides of the sacrum, which is a triangular bone situated at the base of the spine. Each lateral mass can also be referred to as the ala of the sacrum, owing to its wing-like appearance. These masses are highly important as they provide support and stability to the pelvis and entire vertebral column.

   The lateral masses of the sacrum are wider superiorly, gradually tapering down towards the base. They are flanked by the sacral foramina on their anterior aspect, which allow for the passage of nerves and blood vessels. Posteriorly, they articulate with the ilium bones of the pelvis to form the sacroiliac joints, which provide essential stability during weight-bearing activities.

   The lateral masses of the sacrum serve as attachment sites for various ligaments and muscles. Ligaments, such as the sacrotuberous ligament and the sacrospinous ligament, connect to these bony structures, helping to support the sacrum, stabilize the pelvis, and maintain proper alignment of the vertebral column. Additionally, muscles such as the gluteus maximus and piriformis also attach to the lateral masses, aiding in hip movement and stability.

   Overall, the lateral masses of the sacrum play a crucial role in maintaining the structural integrity and functionality of the pelvis and vertebral column.

2. Bars formed by the fused costal elements at the sides of the coalesced sacral vertebrae.
