Innominate Bone is also referred to as the os coxae or hip bone and is a large, irregularly shaped bone located in the pelvis. It is made up of three separate bones - the ilium, ischium, and pubis - which fuse together during adolescence to form a single, solid bone. This process of fusion typically occurs between the ages of 15 and 17.

The innominate bone plays a crucial role in supporting the weight of the body and providing attachment points for various muscles, ligaments, and tendons. It also protects the reproductive organs, urinary bladder, and parts of the digestive system. Additionally, the innominate bone forms a key part of the bony pelvis, which serves as a structure for the attachment of the lower limbs.

Structure and Function

The ilium is the largest of the three bones and is located at the top of the hip bone. It is characterized by its broad, fan-shaped structure and serves as the attachment point for several muscles of the hip and thigh. The ischium forms the lower and back part of the hip bone and provides support when sitting. The pubis is located at the front of the hip bone and articulates with the other two bones to form the acetabulum, a socket that connects to the femur.

Common Conditions

Due to its complex structure and role in weight-bearing, the innominate bone can be subject to various conditions and injuries. Fractures of the hip bone are relatively common, particularly in older individuals or those who have suffered a severe trauma. Other conditions that can affect the innominate bone include osteoarthritis, bursitis, and osteoporosis.

Overall, the innominate bone is a vital component of the pelvis and plays a crucial role in supporting the body and facilitating movement. Understanding its structure and function is essential for healthcare professionals in diagnosing and treating conditions that affect this important bone.
