Stryker Modular Femoral Heads Hip Replacement Lawsuit

Zoll & Kranz, LLC mass tort attorneys are currently investigating a potential product liability claim involving total hip replacements that used certain Stryker modular femoral heads. We have seen international safety warnings and alerts, including a recall, for the the Stryker LFIT™ CoCr V40™ Femoral Head, a modular head that it can be used with a wide variety of Stryker hip replacement systems. Although this product has not been recalled from the U.S. market to date, our product liability lawyers believe U.S. patients and consumers have a right to know about these warnings.

If you are experiencing adverse events from your Stryker hip replacement or have had a revision, you may have a potential product liability claim. The form here will allow the attorneys to contact you and provide a free case evaluation.

Components of a Total Hip Replacement

The hip joint is where the ball-like head of the femur, or thigh bone, meets the pelvis. The concaved surface of the pelvis where this connection occurs is the acetabulum. When a patient undergoes a total hip replacement, both the acetabulum and femoral head are replaced. The acetabulum is replaced by an acetabular cup that sometimes includes a liner. The prosthetic femoral head is attached to the femur by a femoral stem that goes into the thigh bone. When the femoral head and stem are separate pieces, they connect at the top of the stem, also called the femoral neck, through a taper lock system.

What is the Stryker LFIT CoCr V40 Femoral Head?

The Stryker LFIT CoCr V40 Femoral Head is a metal replacement femoral head made of an alloy of cobalt and chromium. It is a modular head, meaning it is an individual component that can be used with variety of replacement stems manufactured by Stryker. Some of the most common hip stems it is used with are:

  • Accolade TMZF
  • Accolade 2 Femoral Stems
  • Meridian Demoral Stems
  • Citation Femoral Stems

Our attorneys have found that physicians and surgeons are more likely to refer to hip implants by the stem name rather than the head name. As a result, patients may know they have an Accolade hip or a Citation hip but be unaware of what femoral head was implanted. Our attorneys and staff can work with you on determining which femoral head you have.

What are the Safety Warnings?

There is a letter being sent by Stryker to orthopedic surgeons in foreign countries stating, “Stryker has received higher than expected complaints of taper lock failure for specific lots of certain sizes LFIR™ Anatomic CoCr V40™ Femoral Heads manufactured prior to 2011.” The medical device attorneys at Zoll & Kranz, LLC believe U.S. consumers and patients deserve to know this information as soon as possible.

Potential hazards associated with a taper lock failure may include:

  • Disassociation of femoral head from hip stem
  • Fractured hip stem trunnion
  • Excessive metallic debris
  • Insufficient ROM
  • Insufficient soft tissue tension
  • Noise
  • Loss of implant: bone fixation strength
  • Excessive wear debris (polymeric)
  • Implant construct with a shortened neck length

These hazards may then result in harm to patients, such as:

  • Loss of mobility
  • Pain
  • Inflammation
  • Adverse local tissue reaction
  • Dislocation
  • Joint instability
  • Broken bones around the components
  • Leg length discrepancy
  • Need for revision surgery

How Do I Know if My hip Replacement Device is Related to These Warnings?

In the Canadian recall by Health Canada (August 2016) and the Australian Department of Therapeutic Goods Administration (TGA) hazard alert (September 2016) the product numbers were provided as follows:

  • #6260-9-236
  • #6260-9-240
  • #6260-9-244
  • #6260-9-340
  • #6260-9-344
  • #6260-9-440
  • #6260-9-444

Although the existing safety warnings specify certain sizes and specifications of these Stryker modular femoral heads, the attorneys at Zoll & Kranz believe other sizes and specifications may also cause issues. If you may have a Stryker total hip replacement and are experiencing adverse events, you may have a potential claim. As always, please consult your health care providers to address your medical needs.
If you have your medical records you may be able to determine if the product number matches the recalled heads or is a Stryker LFIT™ CoCr V40 Femoral Head. Our experienced mass torts product liability team can assist you in acquiring this information.

Is This Potential Hip Replacement Lawsuit Similar to the Other Litigations?

There are some similarities and some differences. In the previous litigations, such as the Stryker Rejuvanate and AGB II, we have seen safety warnings starting in foreign countries before reaching the U.S. consumer market.

Other hip replacement lawsuits include allegations of metallosis, a type of metal poisoning, resulting from excessive metal debris caused by wear to metal hip implants. This is most commonly seen in the metal-on-metal hip lawsuits focused on metal acetabular cups being used with metal femoral heads.
There are similar allegations of metallosis being made in connection with the Stryker LFIT™ CoCr V40™ Femoral Heads. The difference, however, is in the location of the wear. The metal femoral heads are being used with metal stems, and the connection point between the head and stem is the alleged source of the excessive metal wear debris in the body.

Another difference with this modular Stryker femoral head is that it is used with a variety of other Stryker stems and hip systems, so patients may not be aware they have this potentially defective femoral head.
