Conical posterior iliac horns are anatomical features that refer to bony projections located at the posterior aspect of the iliac bones, which make up part of the pelvis. These projections resemble the shape of a cone, hence the term "conical."
The iliac bones are two large, flat bones that form the uppermost part of the pelvis. They are commonly known as the hip bones and contribute to the structure and support of the pelvis. The posterior aspect of the iliac bones refers to the back side, opposite to the front or anterior aspect.
The conical posterior iliac horns, also known as iliac spurs or horns, are considered anatomical variations due to their irregular presence. They are usually small and pointed, resembling horn-like projections, hence the name. However, their size, shape, and prominence can vary between individuals.
These bony projections are typically found at the posterior or upper part of the iliac crests, which are the curved upper borders of the iliac bones. They may be present bilaterally (on both sides) or unilaterally (on one side). Although the exact cause of conical posterior iliac horns is unclear, they are generally considered to be harmless and non-pathological variations in anatomy.
These anatomical features are often discovered incidentally during routine radiographic examinations, such as X-rays or CT scans. While they do not typically cause any symptoms or medical issues, they may be of importance in certain clinical situations, such as when evaluating skeletal abnormalities, hip disorders, or investigating potential causes of lower back pain.
