Every year in the United States alone, more than 285,000 hip replacements are performed, and the number is expected to double to about 573,000 by the year 2030. The traditional total hip replacement prosthesis, which replaces your damaged hip joint, consists of three parts:
  • a plastic cup that replaces your acetabulum (hip socket)
  • a metal ball that replaces the femoral head
  • a metal stem that is attached to the shaft of the femur

There are also ceramic hip replacements and other alternatives to the total hip replacement -- for example, the Birmingham Hip Resurfacing System.
