Sales Dip for Stryker Following Hip Implant Recalls


Stryker sales have shown a definite dip in the quart since the recall of the Stryker Rejuvenate and ABGII hip implants in July. The hip implant recall came just months after Stryker issued an Urgent Field Safety Notice to hospitals and physicians in April of 2012 citing the potential of fretting and corrosion at the neck juncture as well as the risk of metal ion release. Stryker’s hip implant sales dropped nearly 10 percent while its knee implant sales dropped 4.3 percent.

Why the Dip in Revenues?

A Stryker company official stated the recalls of the Rejuvenate and ABGII had only a “modest impact” on the company’s third quarter drop in sales. While the recalls certainly would have impacted Stryker’s revenues, the overall economy may also have played a part. Joint replacement surgical procedures are considered elective most of the time. Those with insurance may delay the surgery to avoid missing work while those without insurance likely cannot afford the procedure. Stryker’s CFO, Curt Hartman also stepped down after two decades at the helm. He reportedly received a 1.5 million dollar separation package although he will remain as an adviser to Stryker through February, 2013.

Why Diagnosing Problems in Stryker Rejuvenate Hip Implants is So Difficult


When the Stryker Rejuvenate and ABGII were recalled in July of 2012, citing potential risk of fretting and corrosion at the neck juncture, many of the implants had already been removed during revision surgeries. Unfortunately, since most physicians were unaware of the problems with the implants, the operative reports were unlikely to list this corrosion. In other words, since the doctors hadn’t been told what issues to look for, there were few records stating that corrosion was a factor in the revision surgery. When Stryker originally told hospitals and surgeons (in an Urgent Field Safety Report in April of 2012) that there could be corrosion or fretting and release of metal ions, there was still no mention of that corrosion occurring anywhere except at the neck juncture.

Therefore, the neck juncture would likely have been the only place physicians would have examined when taking out the implant. In the same vein, when implant recipients came to their doctor complaining of pain or other symptoms, the doctor would have ordered x-rays, an MRI and a bone scan. Again, without clear information regarding what to look for, many physicians might have attributed their patient’s complaints to external issues such as the aging process.  The Rejuvenate, unlike former metal-on-metal hip implants, is a four-part device with a ceramic ball and a plastic liner in the cup. Because of these improvements, it was believed there would be no metal parts rubbing against one another causing metal ion shear.
