Cincinnati Stryker Hip Attorney

investigating stryker hip implant defects & Hip system recalls

Medical device maker Stryker is facing thousands of injury claims and Stryker hip lawsuits concerning their ABG II and Rejuvenate hip implant systems. Complaints involving the devices include implant failure, spontaneous dislocation, severe pain, inflammation, loss of mobility, and metallosis.

Attorneys involved in the ongoing litigation say thousands of similar claims are surfacing, noting that tens of thousands of Stryker hip replacement systems may still be implanted in injured patients.

The company has been a target of many personal injury and product liability Stryker hip lawsuits. Stryker metal-on-metal hip components like the Stryker Rejuvenate and ABG II have all been targeted by lawyers and patients who allege the devices have caused major injuries and revision operations.

Several Stryker implant recalls have been issued by the U.S. Food and Drug Administration (FDA), and as more and more adverse effect reports come to light, more personal injury claims are filed.

Hip replacement systems can be wonderful quality-of-life improvements, but many patients have suffered from faulty medical devices.

With these hip systems, there is a risk that components will corrode, and cause pain and inflammation in the surrounding tissue. The implant may fail prematurely and lead to numerous secondary infections and painful conditions.

Joe Lyon is a highly-rated Cincinnati, Ohio Medical Device Defect Lawyer representing plaintiffs nationwide in Stryker ABG and Rejuvenate hip lawsuits.

Stryker Hip Lawsuits

Experts say the head and stem connection on some Stryker implants is poor due to an inferior design and material choices that allow the parts to fret and create metal debris. Lawyers and medical experts close to the lawsuits allege Stryker knew for years that some hip system components were defective and dangerous, ad still chose not to report the health risks.

In 2014, Stryker reached a huge settlement with injured patients, but the medical device company continues to manufacture other failing hip implant systems. Stryker is facing allegations of violating various federal regulations and product liability law, including:

  • Failing to report adverse events to the FDA
  • Failing to promptly investigate and analyze device failures
  • Failing to properly warn of the risk of metal toxicity from hip implant devices
  • Negligent design, manufacture and marketing of a defective product

Stryker ABG Hip Implants

Metal-on-metal hip implants have repeatedly been questioned by safety authorities after they cause a myriad of serious complications. A recent study published in The Lancet shows that some metal-on-metal implants are likely to fail much sooner than available alternatives.

The research indicates that patients who receive metal-on-metal implants have a substantially higher overall failure rate—twice the rate of ceramic hips, and three times the rate of metal-on-plastic implants.

The British Medical Journal published a study that concluded systemic metal ions (metallosis) could cause cardiovascular problems. When hip replacements fail, serious side effects are likely. Complicated revision surgeries and infections are relatively common risks for hip replacement patients.

Since its FDA approval and market release, there have been numerous adverse events reported to the FDA. Pain may develop gradually in patients, along with a decrease in range of motion, resulting in a need for revision surgery—additional surgeries are often more complicated and may result in longer recovery times and increased risks. According to the FDA, the signs of a failing hip implant include:

  • Loss of mobility—difficulty with walking and everyday movements
  • Persistent pain
  • Inflammation
  • Infection
  • Dislocation
  • Hip instability
  • Bone Fractures
  • Skin rashes
  • Nerve Damage

Signs and symptoms of metal toxicity include:

  • Impaired kidney function
  • Thyroid disruption
  • Cognitive impairment
  • Skin rashes
  • Hearing or vision problems
  • Cardiomyopathy

Rejuvenate Hip Injury

In July, 2012, Stryker Corporation voluntarily recalled its Rejuvenate and ABG II modular-neck stems.  The initial press release from Stryker states the decision was based on “potential risks associated with fretting and corrosion at the modular neck junction.”

Stryker’s decision to recall their implants not only halted global distribution and future operations, but recommended that surgeons consider the removal of Stryker Rejuvenate and ABG II modular-neck stems.

More recently, in September, 2016, the Australian Therapeutic Goods Administration warned in a hazard alert that the modular components used in Stryker’s Accolade hip replacements have higher-than-expected rates of failures. It has been identified that some LFIT Anatomic CoCr V40 femoral heads manufactured before 2011 have high incidences of taper lock failures.

Australian health officials have identified seven models using the Stryker LFIT hip femoral heads, with head diameters ranging from 36 mm to 44 mm, which may cause issues for patients. An entire line of Stryker’s products with similar specifications has also been included in the hazard alert.

Rejuvenate Revision Surgery

Stryker advises patients with these particular hip replacement systems to schedule a follow-up evaluation with the surgeon who performed the procedure to discuss possible issues.

Qualified medical professionals will evaluate how the hip systems are functioning and can recommend possible treatment. They may order diagnostic testing, including diagnostic imaging on your hip, including X-rays, MRIs, or Ultrasound.

It may be necessary to adjust current post-operative plans. Surgeons may recommend revision surgeries, which are procedures performed to remove the old implants and replace them with new, safer components.  For many patients, hip revision surgery is the only way to resolve pain or reduce serious health risks.

Stryker ABG Hip Recall

Hip replacement surgery has become a very common procedure that can improve a person’s quality of life dramatically. Many patients have lived with pain for so many years that they don’t remember what it feels like to have a pain-free and mobile life. Hip implants have changed that, but in some cases, patients are implanted with defective products, and the situation deteriorates.

Tens of thousands of patients receive hip implants and other joint replacements each year in the U.S. Chronic pain is relieved in most cases. In other cases, patients are plagued with more pain, infections, toxic exposures, and failing hip replacement systems.

In 2012, the Food and Drug Administration (FDA) issued a warning and a Stryker ABG recall for the defective hip implant that caused a number of complications and injuries. The Stryker ABG II hip replacement system was considered a problematic metal-on-metal hip implant product and could potentially release metal into patients’ bloodstreams.

As a result, Stryker Orthopaedics recalled the Rejuvenate and ABG II modular-neck stems, both of which were integral components of Stryker’s hip implant systems. The ABG II modular-neck stem was used with metal and ceramic hip implants. Complications reportedly included chronic pain, inflammation, tissue damage, nerve damage and metallosis.

In 2014, Stryker announced a settlement of the lawsuits for patients implanted with the Rejuvenate or ABG II hip replacement systems prior to November 2014. The settlement was valued at over $1 billion, but Stryker’s liability is not capped and payments to victims could exceed $1 billion dollars.

Medical device manufacturers are held responsible for the safety of their products. The company has a duty to properly test products before releasing them to the market. Stryker, however, did not conduct proper clinical testing on the safety of ABG II hip systems before selling the devices to the public. Several lawsuits seek compensation for pain and suffering.

Defective medical device litigation helps to improve patient safety and holds medical device companies accountable when defective products injure plaintiffs and clients.


Questions about Defective Medical Device Litigation

What is a Defective Medical Device Lawsuit?

When a medical device has the potential to fail and cause injury, companies should voluntarily issue a recall. When a company injures patients with defective medical devices, a medical device lawyer may help you recover financial losses, medical expenses and other damages incurred through litigation.

How is a Product Defined as Defective?
Ohio Definition of Defective

A product is defective if it is unreasonably dangerous for its intended use. A legal cause of action can be based on several types of product defects. The following are Cincinnati product liability and strict liability claims available in Ohio and in most jurisdictions nationwide:

(1)  Manufacturing/ Construction Defect:

These issues arise where the product is released from the factory in a manner that deviates from the intended design or specifications. The defect can be a result of using the wrong materials, including the wrong or completely foreign materials (e.g., Tylenol contamination, food poisoning, damaged car part from factory installation).

As a result of the deviation, the product enters the market in an unreasonably dangerous condition and the consumer is exposed to or purchases a product that is defective. Any personal injuries or economic loss that arise from the the defect are compensable under Ohio product liability law.

(2) Defective design and/or formulation:

Defective design product liability cases arise not because a mistake was made during the manufacturing process, but rather the original design of the product is unreasonably dangerous. A “risk benefit analysis” is used to determine whether safer/less expensive alternative designs were available to the manufacturer.

Federal regulations set minimum standards for the design of many consumer products, and preemption defenses may preclude liability in some situations if the manufacturer follows and obtains federal approval for a product. Automotive recalls and product liability cases are usually a result of a defective design. Common cases include the Toyota Brake Recall, Chrysler Gen III seat belt buckle, lap belt only cases, Metal on Metal hip implants, transvaginal mesh.)

(3) Failure to warn or inadequate warning or instruction associated with the product:

All consumer products come with necessary and appropriate warnings and instructions for use. If the lack of a warning makes the product and use of the product unsafe, the manufacturer is liable for the failure to place the warning. The most common area of litigation for failure to warn is in pharmaceutical litigation.

Pharmaceutical manufacturers are required to warn of the known or foreseeable side effects and update the warnings in a timely manner. Litigation arises where there is evidence the manufacturer failed to timely update a warning in light of new data or simply ignored the risk and failed to conduct sufficient research to identify and then disclose the risk.

(4) Misrepresentation:

The product fails to conform to a representation or warranty. Warranty claims are more common in commercial and economic loss cases than in personal injury cases. In many States, The Product Liability Act does not apply to cases with only economic loss, because the Commercial Code provides recourse for breach of warranty.

The warranty may be written or implied based upon the products intended purpose and merchantability. An example of a breach of warranty cases are cases involving automotive defects.

How do you prove design defects?

Risks:  The following factors are considered under Ohio law when determining the risks associated with the design of a product:  (1) the magnitude of the risk of injury; (2) ordinary consumer awareness of the risk for injury; (3) the likelihood of causing injury; (4) the violation of a private or public standard; and (5) the consumer’s expectation of the performance of the product and level of danger. Ohio Revised Code 2307.5 (B) Product Defective in Design or Formulation.

BenefitsThe following factors are considered under Ohio law when determining the benefits associated with product design: (1) the utility of the product; (2) availability of an alternative design; (3) the magnitude of risks associated with an alternative design. Ohio Revised Code 2307.5 (c)

Defenses for Defective Design(1) a pharmaceutical drug or medical device is not defective by design if it contains an adequate warning of an unavoidably unsafe aspect of the pharmaceutical or medical device; (2) the dangerous aspect is inherent to the product, recognizable, and cannot be eliminated without compromising the product’s usefulness; (3) a lack of a feasible alternative design. 2307.75 (d)(e)(f).


What is a manufacturing defect?
  • A manufacturing defect is based on a defect that occurred during the manufacturing process. Many auto companies have been involved in this kind of product liability lawsuits in recent years, due to defective airbags, software defects, tire failure, and other dangerous manufacturing errors.

    Most manufacturing defect cases are based on a products deviation from the intended specification, formula, performance standards, or design model. In such cases, it may be easy to determine the product did not comply with the intended design.

    The product may be recalled as a specific lot is identified as being non-compliant and defective. A product may be defective in manufacture or construction, materials and assembly, and a manufacturer or distributor may be subject to strict liability, even though it exercised all possible care.  Ohio Revised Code 2307.74.

    Manufacturing Defect Examples:

What is a failure to warn lawsuit?

In determining whether a product is defective due to inadequate warning or instruction, evidence must be presented to prove:

  • The manufacturer knew, or in the exercise of reasonable care, should have known about a risk
  • A reasonable manufacturer would have provided a warning of the risk
  • The manufacturer failed to provide the warning
  • The person was injured due to a lack of warning. The same elements apply whether the claim is based on a warning present during the marketing or post-sale warnings.

Defenses to Failure to Warn Claims(1) the risk was open and obvious or a matter of common knowledge; and (2) in cases of a pharmaceutical drug or medical device, the warning was provided to the prescribing physician (“Learned Intermediary Doctrine”).

Many pharmaceutical companies have been targeted in failure to warn lawsuits for either failing to place warnings on medication guides and packaging or failing to properly test their product before putting it to market.


What are consumer product safety regulations?

Design and manufacturing defects result in thousands of product recalls each year in the United States, initiated by federal safety agencies. Following injury and illness, regardless of recall status, victims and plaintiffs may pursue legal action and contact a product liability lawyer to begin the litigation process. Rightful compensation can be sought and help plaintiffs recover medical costs and other related damages.

Product liability law overlaps with regulatory law, which are the systems of legislative rules and administrative agencies, and part of federal and state governments. These agencies regulate the safety of the products sold to the public. Examples include:

  • The Food and Drug Administration (FDA)
  • The National Highway Traffic Safety Administration (NHTSA;)
  • The Consumer Product Safety Commission (CPSC)

The listed government agencies, however, may initiate recalls of dangerous products but do not provide remedies or compensation for damages where an individual is injured due to the defective product.

Defective products on the market present safety and health hazards for adults and children. Cheap and defective products may pose fire and burn risks; electrocution, strangulation and choking risks; and severe health risks. The manufacturers of consumer products have a duty to foresee potential injury and properly design and test products before they are released.

Companies must also properly warn consumers of any risks associated with their products. Any failure to protect consumers that results in accidents and injury can lead to lawsuits filed by plaintiffs and their Cincinnati product liability lawyer

Our Victories

The Lyon Firm aggressively, professionally, and passionately advocates for injured individuals and families against companies due to a defective product or recalled product to obtain just compensation under the law. 



Nationwide Consolidation in U.S. District Court, Northern District of Ohio. The Depuy ASR Hip design was plagued with problems related to premature loosening and metallosis, caused by chromium and cobalt entering the blood stream. The resulting injuries were a result of the metal-on-metal friction inherent with the design of the product. Depuy recalled the ASR and entered into a global settlement valued at $2.5 Billion to cover an estimated 8,000 patients. The Lyon Firm represented several clients in the original settlement and continues to be active in this litigation. The settlement funds provided compensation for the revision surgeries, including compensating for medical costs, lost wages, and pain and suffering.



Nationwide Consolidation in U.S District Court, Northern District of Indiana. Similar to the Depuy ASR, the Biomet metal-on-metal hip design allegedly contributed to premature hip failures and metallosis due to the metal friction. Biomet entered into a global settlement valued at $56 million to cover a few thousand claims. The Lyon Firm represented several plaintiffs in the original settlement and continues to be active in this litigation.
