You have been given an artificial replacement for your hip joint.

The two hip joints connect the pelvis to the thighbones (femurs). At each side of the pelvic bone there is a depression. This depression is also called the hip socket. The femoral head sits in the hip socket. The femoral head is the rounded top end of the femur.

When a joint is badly worn or injured, it may be painful or less mobile. It is then possible to get an artificial joint replacement. This can involve replacing only certain parts of the joint or the entire joint. The joint replacement is anchored in the bone.

Your femoral head has been surgically replaced by synthetic material.

An artificial femoral head is usually made of metal or ceramic. A wide metal pin anchors the artificial femoral head in the thighbone (femur). Bone cement was used to fix the synthetic material to your bone. Bone cement is a special material that acts like a glue.
