The orthopedic device industry is again preparing to defend itself as concerns about the Stryker V40 Taper present on many Stryker implant devices are showing concerning signs and increasing instances of catastrophic failure – causing serious injury to patients. The metal-related failures that we are now seeing have caused avoidable harm to patients, similar to the avoidable injuries seen in patients that had metal-on-metal and modular hip implants go wrong. Like these past implant failure cases that have been successfully litigated, the result of the current failures to a patient’s health is the same:
If your implant contained the V40 Taper, there are two specific injuries that will qualify you in the Stryker Accolade V40 taper lawsuit:
These cases resemble other metal-on-metal (MoM) and modular hip implant cases. Patients with metallosis will have, some or all of the following:
These cases are rarer, but occur when the V40 taper is ground down by the metal head into the shape of a bird’s beak. Due to this corrosive process, the patient will present with a dissociated head. This means the actual head of the implant will fall off, separating itself from the neck of the implant. For the patient, this greatly increases the potential of a catastrophic injury occurring without warning.
Medical literature is beginning to report that metal-related poisoning is happening in not only both traditional implant designs, but also in one-piece designs where the stem is coupled with a chromium/cobalt head.
There is a growing number of published reports about the catastrophic failure occurring in the heads of implants which are corroding so much, that they start toggling on the trunnion of the patient’s device. This grinds the trunnion down until it ultimately falls off of the stem. The term used by the medical community for this, is spontaneous dissociation. If spontaneous dissociation occurs, an emergency surgical response to remove and replace both the stem and head is triggered. These published reports regarding dissociation all involve Stryker’s Accolade TMZF stem and its LFIT-V40 chrome/cobalt heads.
In addition to the failures mentioned above, there are also numerous reports of premature hip implant failures and the need for revision surgery due to metallosis in patients implanted with these Stryker hip implants.
At present, no formal recall has been announced. However, there is growing concern about the safety of the device and its susceptibility to catastrophic failure as is being seen with the head-neck taper in many Stryker products that use the V40 Head.
