History of the Stryker LFIT V40 Hip
Thousands of people implanted with Stryker hip implants have filed lawsuits against the medical device maker to recover compensation for lost wages, pain and suffering, and other damages, and, as recipients of Stryker’s LFIT V40 femoral head implants learn about the problems associated with the devices, the company is expected to face hundreds, if not thousands, of additional complaints. According to reports, problems with the LFIT V40’s taper lock system, or the portion of the implant connecting the femoral head to the femoral neck, may cause a reaction resulting in corrosion of the metal components. This corrosion may allow metallic ions to be shed into the patient’s bloodstream, which can result in metallosis, or metal blood poisoning.
The problems associated with metal-on-metal hip implants have been well-documented over the years, beginning in 2010, when Johnson & Johnson’s DePuy Orthopaedics subsidiary recalled its ASR XL Acetabular all-metal hip implant system due to a higher-than-normal failure rate. Two years later, Stryker recalled its metal-on-metal Rejuvenate and AGB II hip implants in response to complaints of corrosion and adverse local tissue reactions, and similar complications have since been reported in connection with Stryker’s femoral heads. Still, it wasn’t until August 2016, that the company recalled certain lots of its LFIT V40 femoral heads, due to a higher than expected number of adverse events reported in connection with the implants, including excessive debris shed from the metal components, and “spontaneous disassociation” of the femoral head from the hip stem.
