DePuy Hip Implant Models

Important Update: Two hip implants systems made by DePuy have been recalled due to early failure rates and severe injuries. Contact your doctor if you have a hip replacement system to find out if your hip implant has been recalled.

DePuy has made two ASR™ hip systems, DePuy ASR™ Hip Resurfacing System (only approved for use outside the U.S.) and the ASR™ XL Acetabular System (for use worldwide).

The company sold 93,000 of these hip replacements around the world. DePuy informed its patients that if they received their artificial hip before July 2003, when the devices first became available, they were not subject to the recall.

DePuy Models Recalled

DePuy Orthopaedics, Inc., a Johnson & Johnson company, voluntarily recalled both of these hip replacement systems in August 2010. DePuy and the U.S. Food and Drug Administration (FDA) published notices to both patients and healthcare providers about the recall.

DePuy Models That Failed

Both DePuy's implants have been failing at an unacceptably high rate of 12 to 13 percent within the first five years of implantation. Hip implants generally last 10 to 15 years. There are two main reasons for the implants' failures, the metal-on-metal parts and defects with the ball and cup design.

Problems with the Metal-on-Metal Design

Metal was used in the implants to extend their wear and to allow the artificial ball and cup components of the device to glide more easily against each other.

Problems with the friction of the two metal parts rubbing together have allowed tiny particles of metal to be shed into the surrounding tissues and the blood. The tissues become inflamed and damaged.

Particles released into the bloodstream have been found to be building up to sometimes-toxic amounts in a small number of DePuy patients. Such particles are carried in the blood throughout the body and have been found to be causing symptoms in some patients, indicating damage to:

  • The heart (chest pain and shortness of breath)
  • The nerves (numbness, weakness, or vision and hearing problems)
  • The thyroid (fatigue, feeling cold, gaining weight)
  • Kidney (changes in urinary habits)

Problems with the Ball and Cup Design

The artificial cup, or acetabulum, that fits into the pelvis is too shallow, some surgeons have complained. The design of the cup makes it difficult to implant into the pelvis.

In addition, the artificial ball at the top of the artificial femoral stem (the part that inserts into the thigh bone), has been popping out of the cup because it is too shallow. This is a hip dislocation. When the hip dislocates it is both very painful and a medical emergency.

The FDA issued an alert on hip implant systems. It stated that regardless of the hip system implanted, adverse events may occur. Such events may include:

  • Hip dislocation
  • Bone fracture
  • Infection in the joint
  • Local nerve damage causing weakness or numbness
  • Loosening or breaking of the device
  • Difference in leg lengths
  • Bone loss
