Stryker V40 Femoral Heads Connected with Catastrophic Head-Neck Dissociation

Posted On October 19th, 2016 By CSSFIRM.COM

stryker-lfit-v40Stryker is facing yet another serious problem with their total hip replacement medical devices, this time related to the LFIT-V40 chrome/cobalt heads, which have been reported to potentially cause metallosis or catastrophic dissociation requiring revision surgery. The company previously survived a major recall of its Stryker Rejuvenate and ABGII modular stems in 2012.


In metal-on-metal hip implants, both the head and the liner (or acetabular shell) are made of similar metals, typically cobalt, chromium, molybdenum, and titanium. Friction, or wear, can cause a corrosive process to occur, which may result in severe pain and the need for revision surgery. This process can also lead to elevated metal levels, resulting in a condition known as metallosis.

Metallosis is a relatively rare condition that occurs when metallic debris builds up in the soft tissues of the body. Although metallosis has been observed in various individuals who have undergone hip replacement surgery, patients who have received fully metal implants are most likely to suffer from the condition.

Catastrophic Dissociation

The effects of catastrophic dissociation can be much more serious than a typical metal corrosion case. With catastrophic dissociation, the neck of the stem is weakened to the point of breaking, and if corrosion has eaten away at the neck and caused a break at the head-neck junction, the patient will need a much more invasive revision surgery with complete removal of a well in-grown stem.

Removal of a well in-grown stem is a very serious operation that is susceptible to many complications, and a surgeon typically won’t even try to perform this operation, instead referring the patient to a specialist.

Stryker Hip Lawsuits

Stryker lawsuits have been consolidated into multi county litigation (MCL) in the Superior Court in Bergen County, New Jersey, and into multidistrict litigation (MDL) in the U.S. District court of Minnesota. Atlanta law firm Childers, Schlueter & Smith, LLC has filed more than 25 additional Stryker hip cases in the last six months on behalf of injured clients from all over the U.S.
