protesis_caderaThe hip is one of the largest joints of the body. It is a ball joint formed by the acetabulum, which is part of the large bone of the pelvis. The spheroid part is the femoral head, the upper end of the thigh bone. Bone surfaces are covered with articular cartilage, a soft tissue that lines and cushions the bone ends and enables them to move easily. The hip joint is surrounded by a soft tissue called the synovial membrane. In a healthy hip, this membrane generates a small amount of fluid that lubricates the cartilage and eliminates almost all the friction during the hip movement. Tissue bands called ligaments connect the head to the cavity and provide stability to the joint. The most common cause of chronic hip pain and disability is arthritis. Osteoarthritis, rheumatoid arthritis and post-traumatic arthritis are the most common forms of this disease.


Hip Replacement:

protesis_cadera1Hip replacement is performed when there is irreversible joint damage which occurs in advanced cases of arthritis, rheumatoid arthritis, septic arthritis after effects or developmental dysplasia of the hip, tumors, or in special cases of femoral neck fractures.

In a total hip replacement, bone and cartilage are removed and replaced with prosthetic components.

  • The damaged femoral head is removed and replaced by a metal rod which is placed in the hollow center of the femur. The femoral stem can be cemented or “snap-fit” within the bone.

  • A metal or ceramic head is placed at the top of the stem. This head replaces the damaged femoral head that was removed.

  • The damaged cartilage surface of the cavity (acetabulum) is removed and replaced by a metal cavity. Sometimes screws or cement are used to keep the cavity in place.

  • A plastic, ceramic or metal spacer is inserted between the head and the new cavity to allow a smooth sliding surface.
