Companies like DePuy Caught Paying Ortho Docs Millions- But For What?

Of course, companies like DePuy have deep pockets, but until this article in USA Today, it wasn’t clear just how deep.  The Archives of Internal Medicine conducted a study showing that 41 orthopedic doctors accepted over 114-million dollars from companies like DePuy & Zimmer in “payments.”  What exactly those payments were for is unclear, but you can use your imagination.  Here’s an excerpt from the article written by Steve Sternberg of USA Today.  The link to the complete article is below.

“The medical device industry’s practices were so flagrant that they prompted an investigation by the Justice Department. Indeed, the payments reported in the new study appear in Internet listings set up by five big orthopedic device makers — Zimmer, DePuy Orthopaedics, Biomet, Stryker and Smith & Nephew — as part of a September 2007 settlement that capped a federal inquiry of company kickbacks to doctors. Zimmer, DePuy Orthopaedics, Biomet and Smith & Nephew also paid the government $311 million in penalties.”

Metal on Metal Bearings: Better or Worse?

Interesting questions posted by the Dept. of Medical Engineering and Physics at the Royal Perth Hospital in Australia. Notice how they specifically cite the Depuy ASR Hip as an example of problems with the bearings.  Even more interesting, the bulletin was published in March 2010- 5 months BEFORE the official Depuy ASR Hip Implant recall.   

Metal on Metal Bearings:  How Effective?
March 2010
The increase in use of metal-on-metal (MoM) bearings over the past 5 years has been
dramatic. The claimed advantages of low wear and reduced dislocation risk should be balanced
against increased metal ion release and generation of fine metal wear particles. The
Australian Joint Registry (2009) identified MoM bearings, in particular ASR (DePuy) and
Durom (Zimmer) resurfacings, as having higher than average revision rates. In 2008, the FDA
issued a recall on Durom cups because of unacceptable loosening rates. Durom and ASR MoM bearings sent for analysis, show high rates of loosening (41%), extensive wear markings on the articular surfaces, and fine corrosion pitting near the rim of the heads. All components are Co-Cr-Mo alloy but differ in composition and manufacturing (cast or forged). Some of the microstructures revealed carbide precipitation at the grain boundaries – features that can affect wear and mechanical performance. Some questions remain:
• What is the cause of fine corrosion pitting on the bearing surfaces despite excellent
in vitro corrosion resistance?
• What is the relationship between metal hypersensitivity, osteolysis and implant
failure (loosening, infection)?
• Is there a correlation with increased reporting of pseudotumours or ALVAL with
usage of MoM bearings?

How Many US Patients have Defective DePuy ASR Hip Implants?

A worldwide recall is never a good thing for a company.  And when you break down the numbers in DePuy’s recent ASR hip implant recall, the statistics don’t look good for patients in the United States. Take a look at the math:

93,000- The number of ASRs sold and implanted worldwide
11,160- The probable number of failed hip implants worldwide according to DePuy’s reports of a 12% failure rate.
 
But here’s where the numbers start to look bad for US patients:
4,000  Number of DePuy ASR hips sold/implanted in the UK
8,000  Number of DePuy ASR hips sole/implanted in Australia
12,000-  Total number in both UK & Australia.
12% failure rate= at least 1440 defective hips in the UK and Australia.
 
That still leaves almost 10,000 patients around the world with a high probability of having a defective DePuy ASR hip.  HOW MANY OF THESE DEFECTIVE HIPS WERE IMPLANTED IN US PATIENTS?  The numbers are likely to be very high with patients in the United States suffering from the majority of these defective products.

Not good statistical odds for anyone in the US who has a DePuy ASR hip implanted into their bodies right now.
