Hot New Project – Stryker Accolade V40 Taper Failures

September 2016

Hot New Project – 
Stryker Accolade V40 Taper Failures
After a decade of receiving several black eyes over failed metal-on-metal and modular hip implants, the orthopedic device industry is bracing itself for yet another wave of metal-related failures and avoidable harm to patients. 

The medical literature is starting to report metal-related poisoning in traditional implant designs. These metal-related failures are occurring even in situations where a one-piece stem is coupled with a chromium/cobalt head. The location of this implant failure is different than those reported (and litigated) in the past; but the result is the same: metal poisoning, bone and tissue damage, and unnecessary revision surgery due to premature hip implant failure.
What To Look For?
With the Stryker Accolade V40 cases, we are looking for two different types of injuries:  

1.  Metallosis cases – These cases resemble other metal-on-metal (MoM) and modular hip implant cases, where patients present with increased levels of cobalt and/or chromium, pseudotumors, bone and tissue damage, inflammatory fluid around the implant, development of severe pain several years after the index surgery, need for revision surgery due to premature device failure, etc.
2.  Dissociation cases – These cases are rarer, but occur when the V40 taper is ground down by the metal head into a bird beak shape. This corrosive process is particularly violent, and the patient will present with a dissociated head. In other words, the actual head of the implant will fall off and separate from the neck of the implant, which causes catastrophic injuries to the patient and often occurs without any warning. 

Will There Be A Recall? 

At this time, a formal recall has not been announced; but there are growing concerns over this critical safety issue that is being seen with the head-neck taper in many Stryker products that utilize a V40 head.  However, we are sure that there is a problem with the head-neck taper in many Stryker products that use a V40 head.  

There are published reports in the medical literature of multiple catastrophic failures where the heads of the implants corrode so much so that they start toggling on the trunnion. Once that process starts, the head grinds the trunnion down and ultimately falls off of the stem. The medical term used for this is spontaneous dissociation. That event triggers a surgical emergency for removal and replacement of the stem and head.  These published reports regarding dissociation all involve Stryker’s Accolade TMZF stem and its LFIT-V40 chrome/cobalt heads.  There are also numerous published reports of premature hip implant failure and the need for revision surgery due to metallosis in patients implanted with these Stryker hip implants.

Searcy Denney filed the first Stryker Rejuvenate and ABGII hip implant lawsuits following the recall of those products in 2012, and Cal Warriner was court-appointed to the negotiations team that successfully negotiated a $1 billion global settlement. We have also filed a number of lawsuits involving dissociation and metallosis with Stryker’s Accolade TMZF stem and its LFIT-V40 head over the past few years. Please let us know if we can assist you and your clients with any Stryker hip implant claims.  
We are currently accepting referrals for these cases, and we look forward to working with you and your clients.  (800) 388-3905 or email us at
