Study Finds Corrosion-Related Failure in Stryker Rejuvenate Hips
Hip lawsuits against Stryker Orthopaedics are pending across the U.S. as more plaintiffs come forward in an attempt to seek compensation for injuries allegedly sustained due to the Stryker Rejuvenate hip implant. Recently, researchers in Houston, Texas at the Houston Methodist Hospital conducted a study to determine the rate of corrosion that could ultimately lead to early device failure as well as the expected lifespan of this particular hip implant model. Researchers also wished to analyze the relationship between patient factors and implant differences in correlation with the necessity for revision procedures and elevated metal ion levels.
If you or a loved one received the Stryker Rejuvenate hip implant and experienced metal toxicity, early device failure or other complication as a result of the device, you may be eligible to join the growing number of plaintiffs across the U.S. who are filing hip lawsuits against Stryker.

Study Shows Stryker Rejuvenate Hip Implant Likely to Fail
Published on March 19, 2014, the study analyzed data from 104 patients fitted with 123 Rejuvenate hip stems. Researchers followed participants between June 2009 and July 2012 and measured chromium and cobalt levels in each of the patients. One surgeon was responsible for implanting each of the units to reduce surgeon inconsistency.
Patients who reported hip pain or high metal ion levels were required to undergo magnetic resonance imaging so that researchers could assess adverse local tissue reactions. With this data in hand, researchers were then able to analyze different factors including the head size and length, the femoral head-neck offset and stem size as well as age, sex and body mass index of the patients. These factors were then compared to the metal ion levels that had previously been noted.
Scientists found that the corrosion rate of the Stryker Rejuvenate hip implants over the short-term was astounding. After an average of two and a half years, researchers noted that chromium and cobalt levels were 2.1 and 5.4 – notably high for the short time period. Additionally, the differences in the levels of metal ions in the blood stream between the non-modular and modular groups were substantial.
After analyzing all of the data, researchers concluded that 48 percent of patients in the modular group were experiencing elevated metal ion levels when compared to patients in the non-modular group. Additionally, these increased metal levels were directly related to younger patient age and a higher femoral head-neck placement, and both high cobalt levels and increased pain signified a greater risk of requiring a revision procedure.
Stryker Rejuvenate Hip Device Overview
According to adverse event reports submitted to the U.S. Food and Drug Administration and the current hip lawsuits pending against the manufacturer, the Stryker Rejuvenate hip device may cause swelling, pain and metal poisoning which may ultimately lead to early failure of the implant. Additionally, the metal-on-metal components of the unit have the potential to fret and corrode as evident from the results of the referenced study, resulting in the deposit of metal ions into the patient’s bloodstream.
Stryker recalled the ABG II and Rejuvenate implants in July 2012 after the manufacturer reviewed surveillance data that reported an increased risk of corrosion. Following the Stryker recall, patients throughout the country began to seek legal counsel and file hip lawsuits against the manufacturer, alleging that the Stryker Rejuvenate hip implants caused serious and life-threatening complications.
