Medicine Balls Special: Metal Hips, Cancer Scares and the British Medical Journal  

To commercially damage any product, however inadvertently, all you have to do is link it with cancer in the public mind. The ensuing panic benefits lawyers and journalists, but it only helps the public if the risks are substantial and somewhere near proven. In March, a group of angry orthopaedic surgeons contacted the Eye to complain about the link of Metal on Metal (MoM) hips to cancer in the March 3rd edition of the British Medical Journal1 2, and a BMJ-Newsnight ‘special report’ on February 28th 3. The cancer link was picked up in the Sunday Times 4 on March 4th and fuelled an ongoing cancer scare in patients with MoM hips, and patients who weren’t sure what hip they had.

As for patients considering a new hip, who would now choose an MoM when a source as credible as the BMJ states there are ‘substantial concerns about the increased risk of cancer’? But there is no good evidence showing MoM hips cause cancer. Bristol University, one of the leading research centres looking at this told the Eye: ‘It is far too early to make any conclusions’ about any link with MoM hips and cancer. And although cancer scares are regular occurrences in the media, you’d expect better from the BMJ (motto ‘helping doctors make better decisions.’)

This was the second cancer scare orthopaedic clinics had to deal with in only a month. On February 5th, the Telegraph ran a story linking MoM hips to bladder cancer 5, based on unpublished research from Dr Patrick Case and colleagues in Bristol. Because the research was unpublished, NHS staff dealing with anxious callers had no access to any reliable information to give to patients. When the Sunday Times later became interested, Dr Case – a Consultant Senior Lecturer at the University of Bristol – wrote a desperate e mail to colleagues: ‘I have told this journalist that our study does NOT provide the first clinical evidence linking metal-on-metal hip implants to an increased risk of cancer. Our paper is not yet written and it will not conclude this. The journalist has told me that he will change his story. I have warned him of a public scare and have reminded him of the MMR panic.’ The Sunday Times (March 4th) duly lead with the front page headline: ‘Research links hip implants to cancer’.

The research has still not been published and may never be. Of 80 patients studied, one had bladder cancer, he’d only had an MoM hip in for a short time but he was a heavy smoker (a far more likely cause). To make matters worse, a BMJ-Newsnight investigation on February 28th gave another plug to the Bristol scare. ‘We understand that on Thursday, research will be presented looking at the risks of bladder cancer in these (MoM hip) patients.’ The BMJ and Newsnight should have been aware of the widespread panic this ‘non story’ had already caused. The University of Bristol states that no one from the BMJ or Newsnight contacted them prior to broadcast, and that there is, as yet, no clinical evidence linking bladder cancer and MoM hips. And the BMJ had far more substantial research due for publication from the National Joint Registry that was much less alarmist.

On April 3rd, the BMJ published the paper 6 which concluded: ‘In a large representative sample there was no association between metal-on-metal hip replacements and increased incidence of cancer in the first seven years after hip replacement.’ And ‘the one year incidence of cancer after total hip replacement is lower than that observed in the general population.’ But by that stage, the damage in the public mind had been done. As a lawyer from the London firm Leigh Day – which specialises in MoM hip litigation – told the Sunday Times: “The fact that you’ve now got a study which demonstrates that there may be cell changes is very significant.” And doubtless many more clients were flushed out by the scare.

There are failure problems with some types of MoM hip. The DePuy ASR range was removed from the market in 2010 and stemmed MOM implants are failing at much higher rates than other types, particularly those with larger head sizes and those implanted in women, in whom failure rates are up to four-times higher. But other types, such as the Birmingham Hip Resurfacing (which MD would choose for himself), have an excellent track record over 15 years, particularly in large, active men, and the last thing they need is an unsubstantiated cancer scare.

The theory linking MoM hips with cancer is that the metal surfaces of the cup and ball joint wear, producing particles of chromium and cobalt that enter the tissues and blood stream and could one day lead to cancer. Some of the newer MoM hips release more chromium and cobalt than previous models. Whether this is just a marker of wear and tear in the hip, or whether it could lead to distant disease or widespread poisoning has yet to be established. After 7 years of follow up on these models, no proof has been found.

The BMJ is part of a worthy campaign to improve the regulation of medical devices. New rules are currently being drawn up by the European Commission to give the public access to details of the clinical research about all devices and implants, and their safety record. But the BMJ’s high profile campaigning has to tempered with scientific balance. The March 3rd issue seemed to damn all types of MoM implant. ‘The risks of metal on metal hip implants’ had a bold green headline on the cover and the story – and link with Newsnight– was heavily trailed by the BMJ publicity department. The editor’s choice was headlined ‘Serious risks of metal on metal hip implants’ and the only two features in the journal were an investigation titled ‘Hip implants: how safe is metal on metal?’ and an adjacent commentary taking a very similar line: ‘Ongoing problems with metal-on-metal hip implants.’ The coverage was overwhelming negative with no balancing article on, say, the success of the Birmingham hip.

The large print summary in the first BMJ article claimed that ‘hundreds of thousands of patients may have been exposed to toxic substances after being implanted with potentially dangerous hip implants’ and the second opened with ‘substantial concerns currently exist’ about ‘newer (MoM) hip implants and increased risk of cancer.’ MD asked some of the authors to provide details of any patient known to have cancer or poisoning from an MoM implant. There were no cancer patients to be found, and a few possible metal ion poisonings in Alaska. The best we can currently say is more research is needed (see University of Bristol statement below). Far from sounding like the balanced voice of British medicine, parts of March 3rd issue read like a lawyers’ press release. An internet search of ‘hip lawyer bmj’ reveals pages of citations on legal websites in the US and UK, many feeding on the credibility of the BMJ.

The BMJ did at least disclose that one of its expert authors, David Langton, is also an expert witness in a class action lawsuit in the United States in relation to the DePuy ASR MoM implant. But it chose not to declare that he is in a relationship with the BMJ’s investigations’ editor, Deborah Cohen, who wrote the other article and presented the Newsnight film, and who had declared the relationship to the BMJ. Dr Cohen introduced Mr Langton to the other authors, but the BMJ says there is no financial relationship between them, so it did not need to be declared to its readers. Many orthopaedic surgeons and hip manufacturers who were aware of the relationship have other views and in MD’s opinion, the BMJ should either have declared it or simply removed one of these authors from the investigation.


What is certain is that the hip-cancer scare caused considerable short-term distress for patients and a large increase in workload for NHS staff dealing with calls and inquiries. The long term fear is that patients will shun a proven prosthesis such as the Birmingham hip for a less tested variety, and that those with existing MoM hips will ask them to be removed because of the cancer scare when the known risks of revision are far greater than the unproven risk of cancer. In June the BMJ quietly published a paper on line (with no press release or Newsnight film) that concluded 7‘Compared with uncemented and cemented total hip replacements, (the) Birmingham hip has a significantly lower risk of death in men of all ages.’


The BMJ has admitted to the Eye that the evidence linking hip replacements and cancer is ‘sparse’, and for those who read the offending articles in their entirety, this point is made. However, the alarmist headlines, press release and accompanying film had a predictable effect in whipping up anxiety and legal interest. And once a health scare is out of the bottle, as the Eye well knows following its involvement with MMR, er…. it’s extremely hard to put back in.

Statement from University of Bristol re: Sunday Times article –
Research links hip implants to cancer

Researchers at the University of Bristol presented a paper to the Hip Society last week [Thursday 1 March] about an unpublished study on metal-on-metal hip implants.

Contrary to media reports, the study will NOT provide the first clinical evidence linking metal-on-metal hip implants to an increased risk of cancer.

The paper, which has not yet been peer-reviewed when published, is expected to conclude that metal-on-metal hip implants is an important subject and a larger study involving several centres will need to be conducted to show whether or not there is a risk of cancer from metal-on-metal hip implants.

Patients who are concerned about their metal-on-metal hip implants should contact the hospital that carried out the procedure for advice.

Complaints, I’ve had a few

Phil Hammond shares the woes of the GP
The Times

Published at 12:01AM, September 19 2012

When I was training to be a GP, I had two complaints. One was from a patient who didn’t want a ginger-haired doctor, which I felt was a little harsh, and one from the wife of a man who’d died from a malignant melanoma and thought I should have spotted it, which was entirely legitimate. The first woman was reassured by a second opinion that I was in fact strawberry blond. The second woman accepted my apology but never came to see me again.

Her husband had come to see me with diarrhoea and I hadn’t spotted the melanoma on his back. In a six-minute consultation, five of those are taken up by getting the clothes on and off (the patient’s, not mine).

Trying to spot something potentially life-threatening in a minute is both the art and science of medicine and, under such time pressure, we’re never going to get it right first time, every time. But I still curse myself for not turning him over.

Modern medicine harms one in ten patients but, if doctors are open and honest, complaints rarely go further. News yesterday that complaints made to the General Medical Council (GMC) about doctors have risen 23 per cent in the past year suggests that we don’t have the time to sit down and explain what’s happened, and to say sorry. Some complaints are ridiculous — an obstetrician got one for “sweating profusely” while trying to pull out a baby whose shoulders had got stuck — and you should hear the things doctors say about patients in the privacy of the coffee room.

Perhaps we should have one day a year when doctors tell patients the truth about what we think about them. I’ve only known one GP brave enough to do this. He was a senior partner, close to retirement, who summoned patients with “Come on, you big jelly belly. Get that great flabby arse in here.” So maybe too much honesty is a bad thing. But communication is a two-way street, and if doctors and patients treated each other with more compassion, the GMC would have far less work to do.

Lansley’s Chaotic Legacy

There are few more exciting summer reads than the NHS Commissioning Board’s ‘Overarching Programme Update’ (19/7/2012). You can marvel at the ‘CB Operations Directorate’ and the ‘Clinical commissioning group authorisation draft guide for assessors undertaking desktop review.’  The ‘intelligence needs’ of commissioners are discussed, along with the obligatory ‘solutions roadmap.’  And there’s even ‘a revised ready reckoner tool to help CCGs calculate the costs and implications of how they will carry out their functions….’

But most of the fun comes from the latest version of the risk register.  Andrew Lansley still refuses to reveal the original, but it now seems most unlikely that the NHS Commissioning Board  Special Authority will be fully staffed and functioning by the target of April 2013. It needs nearly 4000 staff, but many of the best and most experienced  managers have either been sacked or taken a handsome redundancy package. Recruitment currently has ‘a very high risk of failure’ which would have a ‘level 5’ impact. All this was predicted by Lansley’s critics, including the Eye, but the board is doing its best to disguise the panic in ‘wonk’ speak:

‘There is a (very high) risk that the NHS Commissioning Board (NHS CB) may fail to populate its organisational structure by March 2013. This risk has a number of causes: 1. there may be delays in finalising the NHS CB organisational design, reducing the time available for recruitment; 2. there may be delays resulting from disagreements with sending organisations regarding the nature of functional transfers; 3. the NHS CB may fail to secure sufficient capacity to manage the large volume of recruitment required at the necessary pace; and 4. Trade Unions may challenge elements of the transition process if processes are not properly agreed and implemented.’

As MD is tired of repeating, the last thing the NHS needed in tough times was massive structural upheaval, and the chaos at the centre is such that experienced managers are walking away. This may have been Lansley’s master plan all along – to create space for the private sector to take over commissioning – but in the meantime, frontline care is suffering.  According to the ‘NHS safety thermometer’ (sic), launched in April, nine per cent of all NHS patients suffer ‘avoidable harm’ and in some trusts the figure is more than 20%.  The Department of Health had a target to deliver “harm-free care” to 95 per cent of patients “by 2012”.

In the first 6 months of this year, 66,845 patients waited between 4 and 12 hours for a bed once a decision had been taken to admit them, according to the DH. This is an increase of 31 per cent on last year, and patients are back to waiting in corridors or on trolleys. A+E is getting so crowded that NHS Suffolk posted this helpful message on its website. “Do you seriously think you’re dying? If the answer is no, then it’s likely you shouldn’t be at A&E looking for medical treatment”. The message has sadly now been taken down, but the Mid Staffs inquiry will have taken note. Parts of the NHS are currently too busy to be safe.

There are still job vacancies in the NHS, and not just on the commissioning board. Central and North West London NHS Foundation Trust has advertised for an Assistant Psychologist. ‘We are seeking an enthusiastic and committed individual to join a community service within the Addictions & Offender Care Directorate. You must be willing to work with individuals with substance misuse problems, many of whom also have complex mental health needs. You must possess the relevant skills and attributes to facilitate service users to engage in the service. You must have a strong commitment to teamwork and be able to work sensitively within a culturally diverse environment…. Please Note: These are UNPAID positions.’ Alas the closing date has passed, but more ‘unpaid NHS internships’ are sure to be along soon.
