Please see our Hip Recall Center website for more up-to-date information about metal-on-metal hips.

What are metal-on-metal (MoM) hip devices?

A metal-on-metal hip consists of three components: a ball, a stem, and a shell. There are two types of MoM hips: total hip replacement systems and resurfacing hip systems (also known as acetabular systems). In both systems, a metal head connects to a metal socket to create the artificial hip. In a total hip replacement system, the entire hip joint is reconstructed using metal components. In resurfacing hip systems, the hip socket and head of the femur bone are simply “resurfaced” or replaced with an acetabular metal component.   

What are the risks?

Metal-on-metal hip devices carry their own unique risks in addition to the initial risks associated with artificial hip implants. Due to the manner in which MoM hip devices function, the constant friction between parts can cause device components to loosen. When this happens, metallic ions are released at a high level into the patient’s bloodstream potentially causing harmful reactions within the patient’s body.

Who makes these devices?

Metal-on-metal (MoM) hip devices are manufactured by DePuy, Zimmer, Stryker, Biomet, and Wright Medical, among others.

What types of injuries can metal-on-metal hip devices cause?

When metallic ions are released into the bloodstream the metal particles have the potential to damage the bone and/or soft tissue surrounding the implant and joint. The damage can lead to severe pain, disability, device loosening/failure, and the need for revision surgery. In some cases, patients may develop a form of metal poisoning known as metallosis.
