What are the parts of a natural pelvic joint?

The pelvic joint is a ball and bowl joint. Unlike a hinged joint, this structure has multiple plates of movement and more freedom of movement. In the pelvic joint, the bowl-like part is called the acetabular cavity. This cavity is made up of parts of the three bones: ilium, ischium and pubis.

Numerous soft tissue structures are located around and inside the pelvic joint. The lining section, like around the pelvic joint, is called the capsule. The posterior part of the joint capsule provides a large portion of the vascular nutrition of the femoral head.

Damage to the cartilaginous surface of the joint often necessitates pelvic replacement. The sum of the joint parts forms a strong and integrated structure that in many ways allows the joint to move.

Why is my pelvic joint not working properly?

The destruction of the pelvic joint is gradual, but occurs at different speeds depending on the patient’s condition. When one part of the pelvic joint is defective, the function of the entire joint will change.

The part of the joint that is most damaged is the cartilage of the joint surface. In a healthy, normal pelvic joint, the slip between the two surfaces of the moving bone in the joint is less than the slip between the two ice cubes on each other, but when the joint surfaces are damaged. And the cartilage of the joint is damaged, the movement in the other joint can not be as easily as before. The lesion in one joint surface, the joint surface in front of that area will also be involved, therefore the joint surfaces collapse and the subcutaneous bone is also affected. To take.

As a result of these changes, the joint loses its natural motion and the pressure on the joint surface changes. At the same time, the overlying tissues inside the joint become inflamed.

Replacing the pelvic joint means removing all or part of the damaged pelvic joint and inserting the ball-like part or the ball and bowl together.

In this surgery, the damaged bone and joint surfaces are replaced with prosthetic parts. Because these artificial parts are placed in the patient’s body, they are called implants.
