http://www.depuyhipreplacementlawsuit.com/ Johnson & Johnson (J&J) and its subsidiary DePuy Orthopedics Inc. is in trouble in Britain after a British database suggested that its metal-on-metal hip implants fail within a span of six years. The information was based on the data gathered by the National Joint Registry for England and Wales which pointed that 29 percent of the patients have reported that their implants have failed after only six years of use. The New York Times reported that metal-on-metal implants can cause tissue and muscle damage.

DePuy ASR Metal Hip Implants Fail after 6 years of Usage says British Study

  1. 1. As Published on the DePuy Hip Replacement Recall Website
  2. 2. Johnson & Johnson (J&J) and its subsidiary DePuyOrthopedics Inc. is in trouble in Britain after a Britishdatabase suggested that its metal-on-metal hipimplants fail within a span of six years. The informationwas based on the data gathered by the National JointRegistry for England and Wales which pointed that 29percent of the patients have reported that their implantshave failed after only six years of use. The New YorkTimes reported that metal-on-metal implants can causetissue and muscle damage.
  3. 3. After the DePuy announced a worldwide recall of twoof its hip replacement systems, the ASR XLAcetabular System and the DePuy ASR HipResurfacing Platform, last August 2010, the NationalJoint Registry for England and Wales started trackinghip replacement problems in Britain. The release ofmedical studies which suggested that the metal-on-metal hip implants had a high failure rate in starkcontrast to its 15-year life expectancy prompted therecall. However, more than 90,000 DePuy ASR XLAcetabular Systems and DePuy ASR Hip ResurfacingSystems have already been sold worldwide before therecall and about 40,000 of those were sold in theUnited States.
  4. 4. The manufacturers had expresseddoubts that the rate could be as highas the British registry is calculating forthe hip implants failure at six years.However, with 17 percent of BritishASR hip recipients reporting failures,even the registry’s five year failure ratenumbers are higher than themanufacturer’s estimates. Theproblems on metal-on-metal hipreplacements are not limited to therecalled DePuy ASR implants as all hipimplants that feature metal-on-metaldesigns appear to have a higher failurerate than other types of artificial hips,according to the registry data.
  5. 5. Although the registry data showed that compared to themetal-on-metal hip implants which have a failure rate of14 percent, other types of hip implants includingcombinations of ceramic, plastic and metal only have a4.7 percent failure rate after seven years. Part of theconcern for this high failure rate is a defective hipimplants potential to cause metal toxicity among itsrecipients. According to Parker McDonald P.C., a Texaslaw firm, which represents plaintiffs seeking remedies formedical issues arising from the failure of metal-on-metalhip implant devices, the cup in the recalled ASR device isso shallow that it is susceptible to so called “edgeloading,” a situation wherein the joint’s ball strikesagainst the cup’s edge and causes the implant parts torub together and chisel off debris that releasesmicroscopic ions of the heavy metals chromium andcobalt into the body.
  6. 6. There may be a need to undergo arisky hip revision surgery as metaldebris inside the body could result insoft tissue damage, inflammatoryreactions, bone loss, geneticdamage, asceptic fibrosis, localnecrosis or other problems. Nearly4,000 of the 5,000 complaintsreceived by the US Food and DrugAdministration (FDA) on metal-on-metal hip replacement involveDePuy. J&J has bulked up its liabilityfund by $570 million to cover thecost of DePuy ASR settlement asmore lawsuits are expected to befiled against J&J despite the hipreplacement recall.
