DePuy Pinnacle and DePuy Ultamet Verdict Updates:

March 2016: DePuy and Johnson & Johnson found liable for $498 million for five plaintiffs in Texas.

December 2016: DePuy and Johnson & Johnson found liable for $1.04 billion for six plaintiffs in Texas.

Overview

The Pinnacle Acetabular Cup System was introduced in 2001 by DePuy Orthopaedics, a subsidiary of the Johnson & Johnson company. The hip system has several variations, including some containing a metal liner which is the metal-on-metal (MOM) design.

Description

In May 2011, the Judicial Panel on Multidistrict Litigation approved consolidation of the numerous federal cases for multidistrict litigation (MDL) in the U.S. District Court for the Northern District of Texas, before Judge James Kinkeade. Such consolidation helps reduce duplicative discovery in different cases, eliminates inconsistent rulings from different judges and serves the convenience of the parties, lawyers and the courts.

All of the lawsuits involve similar allegations that the DePuy Pinnacle Acetabular Cup System was defectively designed or manufactured, and that inadequate warnings were provided about the risk of complications or problems following hip replacement.

In October 2011, the American Academy of Orthopaedic Surgeons (AAOS) issued a warning about potential problems with metal on-metal hip replacements, indicating that patients and the medical community should be aware that pain months after hip replacement surgery may be a sign of metal-on-metal complications, including metallosis and toxicity.

Diagnosis

After installation of the system, design defects cause an increased risk of problems from microscopic metal particles that are shed from the DePuy Pinnacle hip implant when parts of the metal-on-metal hip system rub against each other, increasing the risk of metallosis, biologic toxicity, and lead to a high failure rate. This can lead to inflammation, swelling, loosening of the parts and ultimately may cause the hip replacement to fail, resulting in the need for hip revision surgery.

Symptoms:

Metallosis:

  • Inflammation/Swelling
  • Intense paint at the site of hip replacement
  • Groin or thigh pain
  • Spontaneous dislocation
  • Tissue Mass or Rash
  • Black tissue
  • Bone Deterioration

Long term effects:

  • Chromosomal Damage
  • Carcinogenesis ( development of cancerous cells)
  • Increased Lymphocytes (Lymphocytosis- results in “sick” symptoms)
  • Necessity for additional surgeries to remove implants, mass tissue buildup, or infected bones.
