Stryker Corporation's LFIT V40 Hip Implant Device Controversy
The Stryker Corporation is a manufacturer of components for orthopedic surgery, with a focus on hip implant surgery. Certain devices made by Stryker have been subject to complaints, recalls and even lawsuits. Arguably, the most notable of these were the ABG II and Rejuvenate Modular Hip Stems. Since then, Stryker LFIT V40 femoral heads—a component in many of Stryker’s hip systems—has made headlines for its tendency toward high failure rates and the company’s quiet recall of the product.
These cases concern defects in Stryker-branded LFIT Anatomic Cobalt-Chromium V40 femoral heads, used in total hip replacement surgery from 2002 to 2011. In August 2016, Defendant Howmedica Osteonics recalled more than 42,000 of these hips. At the same time, medical authorities in Canada and Australia also issued recalls. This recall follows a 2012 recall of Stryker Rejuvenate and ABGII litigation.
Understanding the Stryker LFIT V40
Modern hip implant technology often involves multiple components that make up the hip replacement, including the femoral stem, femoral neck, and, the femoral head. The Stryker LFIT V40 falls into the last category and is placed above the femoral neck and inside the hip socket.
Stryker uses LFIT V40 femoral heads in the following hip stems:
- Accolade TMZF
- Accolade 2
During a total hip replacement surgery, the LFIT V40 is fastened onto a femoral hip stem trunnion at the femoral neck through an element of the LFIT V40 known as a taper lock.
While Stryker claims the LFIT V40 femoral heads are more durable than other femoral heads on the market, most complaints about the hip implant device are focused on its high incidence of taper lock failure, specifically in LFIT V40 devices manufactured before 2011.
LFIT V40 Failure Symptoms
When the Stryker LFIT V40 taper lock fails, a variety of problems can occur. In some cases, the femoral head may even become dislocated from the stem, which can also contribute to metal debris being released into the nearby tissue and bone (a condition known as metallosis or metal poisoning). Potential hazards include:
- excessive metal debris
- disassociation of the head from the femoral stem
- trunnion fracture
- metal corrosion
- adverse location tissue reaction
- loss of mobility
Litigation regarding alleged defects in Stryker-branded LFIT Anatomic CoCR V40 femoral heads, a prosthetic hip replacement device, has been assigned to Judge Indira Talwani in the United States District Court for the District of Massachusetts as an MDL (multi-district litigation) for pretrial proceedings.
