Hip joint deterioration occurs when the cartilage or bones going through changes and can lead to pain, stiffness or difficulty walking. Typical treatment starts with non-surgical therapies such as as physical therapy if the issue is caught early on. If the joint has suffered damage that cannot be helped by therapy, patients have the option to undergo a total hip replacement or hip resurfacing. One common form of hip replacement involved the use of metal-on-metal hip implants who parts are made out of metal.  

The Hip Joint

The New York Presbyterian Hospital describes the  hip joint as a ball-and-socket joint with a socket area known as the acetabulum while the ball part is the top of the leg bone. Cartilage separates the hip joint and the pelvis. when normal, the hip joint is critical for everything from walking, running to climbing.

The cartilage or bones that make up the hip joint can deteriorate for a variety of reasons, leading to pain, stiffness or difficulty walking.

Metal-on-Metal Hip Implant Systems

Metal-on-Metal (MoM) hip implants consist of a ball, stem and shell, all made of metal materials. MoM hip implants were designed to offer the following benefits:

  • Less device material wear is generated when the ball and socket rub against each other in comparison to other hip implants

  • Decreased chance of dislocation when the ball of the thighbone (femur) slips out of its socket in the hip bone (pelvis)

  • Decreased chance of device fracture  

There are two types of MoM hip implants:

  • Traditional total hip replacement systems

  • Resurfacing hip systems

Traditional Metal-on-Metal Total Hip Replacement Systems

Metal-on-metal total hip replacement systems consist of a metal ball (femoral head), a metal femoral stem in the thighbone, and a metal cup in the hip bone (acetabular component). The ball attaches to the taper of the stem.

Metal-on-Metal Resurfacing Hip Systems

Metal-on-metal resurfacing hip systems consist of a trimmed femoral head capped with a metal covering. Any damaged bone and cartilage within the socket are removed and replaced with a metal acetabular component.

On Jan. 17, 2013, the FDA issued a Safety Communication to provide updated safety information and recommendations to patients and health care providers.

On May 6, 2011, the FDA instructed manufacturers of MoM total hip replacement systems to conduct  postmarket surveillance study of these devices.
