Although each procedure varies, generally, surgery to replace a hip usually lasts a few hours.
The two most common types of artificial hip prostheses used in replacement surgery are cemented prostheses or uncemented prostheses. Sometimes, a combination of the two types is used to replace a hip. A hip prosthesis is made up of metal and plastic. A cemented prosthesis is attached to the bone with a type of surgical cement. An uncemented prosthesis attaches to the bone with a fine mesh of holes on the surface, in order for the bone to grow into the mesh and attach naturally to the prosthesis.
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.
