sakralrand

Sakralrand is a term used in anatomy to describe the superior, posterior border of the sacrum, which articulates with the fifth lumbar vertebra. This articulation is part of the lumbosacral joint, a critical structure for weight transfer from the spine to the pelvis. The sacralrand is formed by the superior articular facets of the sacrum, which are covered with hyaline cartilage. These facets engage with the inferior articular facets of the fifth lumbar vertebra.

The shape and alignment of the sakralrand can vary among individuals and can be influenced by factors such as age and posture. Variations in the sakralrand's morphology can sometimes be associated with lumbosacral pain or instability. The integrity of this joint is important for maintaining spinal stability and facilitating movement. Imaging techniques such as X-rays and CT scans are often used to visualize the sakralrand and assess its condition.
