höftbensryggraden

Höftbensryggraden, also known as the iliac crest, refers to the superior border of the ilium, which is the largest of the three bones that make up each side of the pelvis. This prominent, curved ridge is easily palpable and forms the upper part of the hip bone. The iliac crest is characterized by its inward curvature, creating a concave shape. Its anterior end terminates at the anterior superior iliac spine, a well-defined bony projection, while its posterior end extends to the posterior superior iliac spine. The crest is a significant anatomical landmark and serves as an attachment point for several important muscles, including the abdominal muscles like the external and internal obliques and the transversus abdominis, as well as the quadratus lumborum muscle. These muscular attachments play a crucial role in trunk stability, movement, and posture. In medical contexts, the iliac crest is frequently used as a site for bone marrow aspiration and biopsy due to its accessibility and rich blood supply. It is also a common site for autologous bone grafting procedures.
