What are the two anatomic structures of the pelvis related to AIS coding?

The pelvic ring and acetabulum are indeed the two anatomical structures related to AIS (Abbreviated Injury Scale) coding. The pelvic ring refers to the bony structure that forms the base of the spine and supports the weight of the upper body as well as the organs in the pelvis. It consists of various bones including the ilium, ischium, pubis, and sacrum, which together provide stability and allow for the attachment of muscles and ligaments.

The acetabulum is the deep socket in the pelvis that accommodates the head of the femur, forming the hip joint. This structure is critical in the context of injury coding as it relates to fractures or dislocations that may significantly impact mobility and function.

Other options focus on structures that, while important in anatomy, do not hold the same relevance in the context of AIS coding. The pubic symphysis and iliac crest, for instance, are related to the pelvic region but do not encompass the same scope of injury classification. Similarly, the ischium and sacrum, while part of the pelvic anatomy, do not capture the complete framework needed for effective AIS coding. Lastly, the femur and tibia are bones of the leg and are not part of the pelvis
