NJR research finds metal-on-metal hip replacement patients are at no more risk of developing cancer in seven years following surgery (National Joint Registry)
A study commissioned by the National Joint Registry, published online at bmj.com today (British Medical Journal, Wednesday 4 April), confirms that patients who have had a metal-on-metal hip replacement are at no more risk of developing cancer in the first seven years after surgery than the general population. The authors of the research add that a longer study is required, to monitor incidences for cancers that take many years to develop.
The study was carried out by the NJR statistical support, analysis and research team led by Professor of Orthopaedic Surgery Ashley Blom at the University of Bristol, who said:
"The results, using a large representative sample, show that there is no association between metal-on-metal hip replacements and increased incidence of cancer in the first seven years after hip replacement."
"The data also shows that the incidence of cancer diagnosis is low after hip replacement in general and lower than that predicted for the age and sex matched general population. However comparisons with the genera...
