Expert Advisory Group report: soft tissue reactions associated with MoM hip replacements | MHRA UK | October 2010 An Expert Advisory Group (EAG) involving members of the British Hip Society (BHS), the British Orthopaedic Association (BOA), the Medicines and Healthcare products Regulatory Agency (MHRA), and the National Joint Registry of England and Wales (NJR) was set up to: determine the incidence of this problem; and advise clinicians on any modifications to current practice which may be necessary to minimise the risk of this adverse reaction and optimise early detection.

Editorial: Metal on Metal: Is It Worth the Risk? | The Journal of Arthroplasty Vol. 25 No. 1 | 2010 There has been an explosion in the use of metal?on?metal bearings in the last 5 years throughout the world. This has mostly been driven by the use of metal bearings in resurfacing, although metal heads have also been used in conjunction with primary total hip arthroplasties. The move to metal heads has primarily been driven by a desire to use larger articulations to reduce dislocations, although smaller metal head combinations are also available and are used clinically. The questions to be addressed in this editorial are firstly to ask if metal bearings do confer a clinical advantage and secondly to look at the potential downside with the use of metal heads.

Metal Sensitivity in Patients with Orthopaedic Implants | The Journal of Bone and Joint Surgery (2001) All metals in contact with biological systems undergo corrosion. This electrochemical process leads to the formation of metal ions, which may activate the immune system by forming complexes with endogenous proteins.

Patients reveal agony of toxic hip implants | ABC News | 16 May 2011 A medical scandal that has resulted in hundreds of patients being poisoned and seriously disabled may soon lead to changes in the way medical devices are approved for use in Australia. By Quentin McDermott and Karen Michelmore.
Hip Makers Told to Study More Data | New York Times | 10 May 2011 In an unusual move, the Food and Drug Administration has ordered all producers of a popular category of artificial hip to undertake studies of the implants, which have been linked to high early failure rates and severe health effects in some patients. Under the order, producers of “metal-on-metal” hips will have to conduct studies of patients who received the device to determine, among other things, whether the implants are shedding high levels of metallic debris. Some patients have encountered that problem, including soft tissue damage that has disabled them.
Hip surgery ruins lives | SMH | 13 March 2011 Jacqueline Gray enjoyed dancing, had a passion for surf lifesaving and did her own shopping. Now the 53-year-old, who lives near the beach on the NSW mid-north coast, has lost her hair, is unable to walk without help and lives in excruciating pain… Mrs Gray, who has joined the class action, is unable to get around without help despite numerous surgical procedures. She takes painkillers daily and has lost her hair due to the level of chromium in her body.
With Warning, a Hip Device Is Withdrawn | New York Times | 9 March 2010 A unit of Johnson & Johnson, just months after saying it was phasing out an artificial hip implant because of slowing sales, has warned doctors that the device appears to have a high early failure rate in some patients. The action by the company, DePuy Orthopaedics, follows more than two years of reports that the hip implant, which is known as the ASR, was failing in patients only a few years after implant, requiring costly and painful replacement operations.
Concerns Over ‘Metal on Metal’ Hip Implants | New York Times | 3 March 2010 Some of the nation’s leading orthopedic surgeons have reduced or stopped use of a popular category of artificial hips amid concerns that the devices are causing severe tissue and bone damage in some patients, often requiring replacement surgery within a year or two. In recent years, such devices, known as “metal on metal” implants, have been used in about one-third of the approximately 250,000 hip replacements performed annually in this country. They are used in conventional hip replacements and in a popular alternative procedure known as resurfacing.
Tasmanian leads hip class action | ABC News | 28 February 2011 A Tasmanian woman is leading a class action against a UK producer of faulty hip implants.

The Quality of Artificial Hips and Knees | ABC Health Report | 21 Nov 2005 Tens of thousands of people have hip and knee replacements every year – and they’re getting younger and younger. But how do you know that the artificial joint the surgeon wants to use in you is up to the job? An Australian survey has found several which aren’t and the result is unnecessary repeat operations which cost millions each year, and delayed operations due to long waiting lists. Read more.

Medical Device Alert | Medicines and Healthcare products Regulatory Agency UK | 22 April 2010 The MHRA has received reports of revisions of MoM hip replacements involving soft tissue reactions… The majority of patients implanted with MoM hip replacements have well functioning hips and are thought to be at a low risk of developing serious problems. A small number of patients implanted with these hips may, however, develop progressive soft tissue reactions to the wear debris associated with MoM articulations. The debris can cause soft tissue necrosis and adversely affect the results of revision surgery. Early revision of poorly performing MoM hip replacements should give a better revision outcome.

Poor outcome of revised resurfacing hip arthroplasty | 2009 BACKGROUND AND PURPOSE: Recent years have seen a rapid increase in the use of resurfacing hip arthroplasty despite the lack of literature on the long-term outcome. In particular, there is little evidence regarding the outcome of revisions of primary resurfacing. The purpose of this analysis was to examine the survivorship of primary resurfacing hip arthroplasties that have been revised.
