Hip Joint and Pelvis Medical Illustrations 

After the knee joint the hip joint is the body’s second largest weight-bearing joint and one of the most important joints in the body allowing movement. It also bears the body’s weight and the force of the strong muscles of the hip and leg. All of the various components of the hip joint assist in the mobility of the joint that allows for such range of movement. If there is any damage to any single component this can impact on the whole joint affecting the range of movement and the ability for weight on the joint.

If a hip joint is fractured due to trauma or simply due to old age, there are surgical techniques that can replace the joint with a prosthesis.  The replacement joint is a ball-and-socket prosthesis and is made of two basic components, the ball component  is made of a highly polished strong metal or ceramic material and the socket component is a durable cup of plastic or polyethylene, ceramic, or metal and engineered in such a way that it will duplicate the motions of a human joint and can lead to surgery called total hip replacement, partial hip replacement or hip resurfacing.

Due to the common nature for hip surgery we have often been commissioned to illustrate this particular anatomy and surgical procedure and examples can be seen in the gallery. If you are a customer and are looking for hip replacement illustrations then please get in touch.

Function of the Pelvis

The primary function of the pelvis, or pelvic girdle, is to allow movement of the body as well as protect organs. It is strong enough to take the weight of the body and serve in a mechanical function to transmit the weight of the trunk and upper limbs to the lower extremities. It transmits the weight through the sacrum and ilia to the femora during standing and to the ischial tuberosities when sitting. It also contains and protects the reproductive organs as well as the bladder and rectum. It also provides attachments for a number of muscles and ligaments used in movement.

Anatomy of the Pelvis

The bones of the pelvis are the hip bones, sacrum, and coccyx. Each hip bone contains three bones the ilium, pubis and ischium. There are four articulations within the pelvis, two sacroiliac joints located between the ilium of the hip bones and the sacrum. The sacrococcygeal symphysis is located between the sacrum and the coccyx and the pubic symphysis located between the pubis bodies of the two hip bones.
