Types of Hip Implants

Types of Defective Hip Implants

Hip implants have been helping individuals regain their mobility for decades. Yet in 2008, complaints regarding the newer all-metal hip implants began to arise. These complaints varied from severe tissue necrosis to premature failure of the device, and the results have been catastrophic for thousands of hip implant patients. Since 2009, numerous hip implants have been recalled by some of the biggest medical device manufacturers in the country. Now, thousands of lawsuits are being filed, leading to what has been called the largest, most costly implant problem in the history of the United States.

Hip implant components can be made of varying materials, including polyethylene, metal, ceramic, or a combination of materials. Yet even in the products that incorporate various materials, if two metal components come into contact with each other, then there is a risk for metal fragments shearing off and becoming embedded in the surrounding tissues and in the blood stream. This complication can result in abnormally high levels of metals in the blood stream, a condition known as metallosis, or it can result in tissue death, pain, limited mobility, and implant failure.

There are numerous models and manufacturers of defective hip implants, but the most common products are:

  • Stryker Hip Implants
  • DePuy ASR XL Acetabular Cup System

The Big Hip Manufacturers

6 main hip manufacturers are under fire for their defective hip products. Those manufacturers are already facing intense litigation over their defective products and lawsuits continue to mount in MDLs across the country.

1. DePuy Orthopaedics: DePuy is a subsidiary of Johnson & Johnson, and they have 3 defective hip implant designs that are involved in lawsuits: the Pinnacle Hip Replacement System, the ASR XL Acetabular System, and the ASR Hip Resurfacing System. The two ASR systems have since been recalled. According to recent data, up to 13% of patients who received the ASR Hip Resurfacing System or the ARS XL Acetabular System required revision surgery within 5 years of having the device.

2. Stryker Orthopaedics: Two popular Stryker models were recalled in 2012 for defective designs: the Rejuvenate and the ABG II. Both devices have been associated with implant loosening and metallosis, and the number of lawsuits continues to mount against this manufacturer.

3. Zimmer Holdings: Zimmer’s Durom Acetabular Cup is also facing lawsuits over defects. Reports that the one-piece socket didn’t properly attach to the bone, leading to excruciating pain, prompted their initial recall in 2008.

4. Smith & Nephew: The popular R3 Acetabular System was recalled in 2012 after nearly 4,000 Americans were implanted with the defective hip product. Increased revision surgery and tissue death were just a few of the complications cited after the R3 was determined to have a faulty metal liner.

5. Biomet, Inc.: The metal-on-metal M2a is a modular device with numerous options. Unfortunately, the M2a also resulted in high failure rates, metallosis, and other severe medical complications.

6. Wright Medical Technology: Wright Medical manufactured two hip implant products known as the Conserve Plus and the Profemur Z Hip Stem. Since 2003, nearly 10,000 of these two products have been implanted in patients across the country. They are similar to DePuy hip implants and have been associated with high failure rates and other medical complications.
