What are the Differences Between Cemented and Uncemented Hip Replacement Parts?
Regardless of whether you have traditional or minimally-invasive surgery at PPH, the parts used to replace the joint are the same and come in two general varieties: cemented and uncemented. • Cemented parts are fastened to existing, healthy bone with a special glue or cement. Hip replacement using these parts is referred to as a “cemented” procedure. • Uncemented parts rely on a process called biologic fixation, which holds them in place. This means that the parts are made with a porous surface that allows your own bone to grow into the pores and hold the new parts in place. Sometimes a doctor will use a cemented femur part and uncemented acetabular part. This combination is referred to as a hybrid replacement. The prosthesis (artificial hip) is comprised of the following two components: • Metal ball component • Plastic socket component (which may have a metal outer shell) While undergoing surgery, the patient may be under general anesthesia or awake with spinal anesthesia.
