More Trouble with Stryker Hip Products

This article covers problems with Stryker Corporation hip implants that led to the 2008 recall of the company’s Trident PSL and Hemispherical Acetabular Cups models. For a discussion about Stryker’s 2012 hip implant recall, click here for an updated article.

Only one day after the Food and Drug Administration (FDA) released a letter scolding the Stryker Corporation for not correcting problems with its hip replacement products, the company has said that it is investigating another issue related to those products.

According to CNN (www.cnn.com), Stryker has said that it is investigating an issue with a socket portion of its hip replacement product known as Trident Acetabular Cups that were made in its County Cork, Ireland plant. Although the company has said that this issue is not a danger to patients or related to the problems addressed in Tuesday’s press release from the FDA (see below), many are wondering what’s going on.

The FDA released a letter sent to Stryker concerning an investigation it conducted at Stryker’s Mahwah New Jersey plant from June 1st through July 12th 2007. The investigation uncovered several issues relating to Stryker’s Trident hip-replacement systems.

According to the letter, there have been many complaints about the product’s defects that have resulted in patients having to have additional surgeries. The FDA blasted Stryker for not doing enough to fix the problems. Among some of the problems reported since January 2005 were:

  • Improper seating of hip implants in broached bones resulting in bone fractures.
  • Trident Hemispherical and Trident PSL cups failed to function; hip implant components have poor fixation. In some instances, these problems have required revision surgeries.
  • Squeaking noises of hip implants with ceramic bearing components; some of those problems resulted in revision surgeries due to implant failures (fractures, pain, wear particles, and fragments).

Based on those findings, the FDA concluded that Stryker:

[F]ailed to implement adequate corrective and preventive actions (which would include verifying or validating the corrective and preventive action to ensure that such action is effective) in order to prevent the recurrence of nonconforming product and other quality problems.
