Weitz & Luxenberg is accepting cases of patients with a Stryker Tritanium Acetabular Shell hip implants who are experiencing loosening complications or require or have had revision surgery due to loosening of the acetabular cup.

The Stryker Tritanium Acetabular Shells are designed to fit into the hip socket as part of a total hip replacement. These cups are approved for patients who require, due to degenerative diseases such as arthritis, previous unsuccessful hip surgery, or problems with bone quality, replacement of the acetabulum (the part of the pelvis in which the top of the femur sits).

The implants are made of a titanium alloy and contain the company’s propriety “Tritanium In-Growth Technology,” a highly porous material purportedly intended to help integration with the bone, but which appears, according to medical literature, to instead prevent bone from integrating with the acetabular cups, leading to loosening.

Failure of the Stryker Tritanium Acetabular Shells

Researchers have noted failures of the Stryker Tritanium Acetabular Shells, finding that many of the cups fail to integrate with a patient’s bone over time. These researchers conjecture this is due to the material with which the shells are coated. This integration, called bony ingrowth, is needed to stabilize the prosthesis.

An abstract published in Orthopaedic Proceedings in February 2018 found that more than one third of Stryker Tritanium implants reviewed had evidence of loosening on radiographs. The researchers advocated that patients with Tritanium cup implants be followed closely for evidence of deterioration and loosening.

In an article published in Arthroplasty Today, researchers from New York University’s Langone Orthopedic Hospital observed several cases of loosening in patients with Tritanium cups, noting it appeared the cups had a higher rate of early loosening.

Complications with the Stryker Tritanium Acetabular Shells

Patients with the Tritanium hip socket implants have reported symptomatic complications, including groin and hip pain, as well as trouble walking. Some patients may require or have already had revision surgery to correct loosening-related complications from these implants.

W&L Can Help Patients Harmed by Stryker’s Tritanium Acetabular Shells

Weitz & Luxenberg’s Drug and Medical Device Litigation unit is interested in hearing from anyone who has experienced a failure or loosening necessitating revision surgery after receiving a Stryker Tritanium Acetabular Shell implant.

Contact the firm if:

  • You have had your Tritanium cup (shell) implanted for less than five years, if it has not been revised.
  • Are currently having symptoms or have been informed by a physician the cup (shell) is loose (pain, trouble walking, evidence of loosening seen on radiographs), it is has not been revised.
  • Your Tritanium cup (shell) loosened and you were required or recommended to undergo revision surgery.

Patients may be entitled to compensation for medical expenses, pain and suffering, lost wages, and other costs. An experienced attorney can help you explore all legal options.

W&L’s Drug and Medical Device Litigation unit Co-Chair Ellen Relkin has played a lead role in several major medical device litigations, including helping to secure a $2.5 billion settlement for patients harmed by defective DePuy ASR hip implants and a $1 billion resolution over recalled Stryker Rejuvenate and ABG II hip implants.
