In August of 2016, Stryker Corp recalled more than 42,000 of its LFIT V40 metal femoral head hip implant components. The company notified surgeons and health care facilities that the implants had a higher than expected rate of revision surgery due to a problem known as “taper lock” failure.
Patients also experienced complications of the device including:
- Severe pain
- Loss of mobility
- Joint dislocation
- Metallosis or poisoning
The notice was posted on the website of the U.S. Food and Drug Administration (FDA) and came after regulatory action was also taken in the UK, Canada and Australia regarding the device. It was also not the first recall that Stryker was forced to conduct for its hip implant devices.
Due to the high number of device failures and resulting injuries requiring revision surgery, thousands of Metal V40 hip implant lawsuits have been filed against Stryker Corp. The company is also facing thousands of lawsuit for other hip imjplant devices including Stryker ABG II and Stryker Rejuvenate components.
While some of these lawsuits may have been settled, thousands still remain and more may be expected.
Stryker LFIT V40 Taper Lock Failure
Hip implant devices like the Stryker LFIT V40 hip implant use a ball and socket connection to mimic the natural hip joint. Once secured, the system is intended to provide balance and stability and improve mobility.
Taper lock failure is cited as a major reason for hip implant failure of the Stryker metal V40 device. Taper lock failure occurs when the femoral head or “ball” comes loose from the stem which attaches it to the leg bone or femur.
Taper lock failure may result in:
- Hip fracture
- Loss of range of motion
- Popping or clicking noises
- Loss of bone
- Damage to soft tissue surrounding the implant
- Implant failure
In most cases of taper lock failure, patients experience pain, inflammation and loss of mobility. It may also result in broken bones and generally requires a complicated revision surgery to remove, repair and replace the device. If the failure has occurred suddenly, it may require immediate or even, emergency medical treatment. In some cases, patients will require multiple surgeries to reconstruct broken or damaged bone and joint tissue.
Stryker LFIT V40 Metallosis
The Stryker LFIT V40 femoral head is a metal hip device which is constructed of a high-tech alloy. The alloy is a combination of metals including cobalt, chromium, titanium and others which are intended to produce a strong and durable device but may cause a condition known as metallosis.
Metallosis occurs when fragments, particles and ions are shed from the device surfaces as they grate against one another. These metal pieces and molecules may cause localized poisoning and inflammation in the joint spaces which will result in tissue destruction and device failure.
In some patients, the metal ions may also be absorbed into systemic or body-wide circulation and result in a systemic illness that resembles the flu but can be severe or serious.
Filing a Stryker Metal LFIT V40 Femoral Head Lawsuit
Some Stryker Metal LFIT Hip implant lawsuits have been consolidated into multidistrict litigation (MDL) in the U.S. District Court of the District of Minnesota and some cases may have already been settled, however many may still be expected.
People or loved ones of patients who received a Stryker V40 metal hip implant and who experienced serious complications, device failure or required a revision surgery may be eligible for compensation.
