Experts call for metal hip replacements to be banned
A study published in The Lancet medical journal has revealed that metal hip replacements come with a high failure rate.
The research, which was carried out by a team of experts from the UK, has now prompted calls for hip replacements involving metal joints to be banned.
It comes just a fortnight after the Medicines and Healthcare products Regulatory Agency (MHRA) in the UK said patients with all-metal implants would need annual checkups and blood tests.
The concern is that as the metal joint wears, cobalt and chromium particles break off and enter the patient’s blood stream, which could damage their muscles, bones and inflict neurological problems.

A team of researchers from the University of Bristol claimed the National Joint Registry of England and Wales – the world’s largest hip replacement register – showed “unequivocal evidence” that all-metal implants had worrying failure rates.
After analysing data on over 400,000 hip replacement producers, they discovered the failure rates were higher in women.
“Revision rates for stemmed metal-on-metal implants in women were up to four-times higher,” the report noted.
It added that in men, the need for a second replacement was three-times higher.
Although all hip replacements can fail, the rate was much higher in all-metal implants as opposed to ceramic or metal-on-plastic varieties.
The research showed five years after the initial replacement, 6.2 percent of metal-on-metal implants had failed – causing issues such as coming loose or dislocating – leaving patients needing replacements.
That’s compared to a failure of 2.3 percent in ceramic replacements and 1.7 percent in metal-on-plastic implants.
Apparently, the risk of failure is also linked to the size of the implant –“each 1mm increase in head size being associated with a 2% increase” in failure risk, the report also said.
It concluded: “Metal-on-metal stemmed articulations give poor implant survival compared with other options and should not be implanted.
“All patients with these bearings should be carefully monitored, particularly young women implanted with large diameter heads.”

Dubai's new smart neuro spinal hospital: need to know
We take a look at Dubai's new smart hospital.
What: The Neuro Spinal Hospital and Radiosurgery Centre is a new hospital featuring state-of-the-art technology for spinal, neurosurgical, neurological, orthopaedic, radiosurgery and cancer treatments. The 700 million AED hospital, (equivalent to £138 million), has 114 beds, smart patient rooms, and green spaces for patient rehabilitation, and is four times the capacity of its former premises in Jumeirah. It is also the UAE’s first hospital to have surgical robots.
Where: The hospital is located in the Dubai Science Park. Founded in 2005, Dubai Science Park is home to more than 350 companies from multinational corporations in life sciences, biotechnology and research; over 4,000 people work here each day.
Who: The UAE's Neuro Spinal Hospital and Radiosurgery Centre was first established in Jumeirah in 2002 by Dr. Abdul Karim Msaddi, as the first as the first "super-specialty" neuroscience hospital.
Why: With advanced diagnosis and robotics, the hospital will provide care across neuroscience, spine, orthopaedics and oncology for people residing in the UAE, as well as international patients.
Prof. Abdul Karim Msaddi, Chairman and Medical Director of the hospital, said: “We are proud to bring world-class healthcare services to Dubai and believe our next-generation hospital will be a game-changer for the emirate’s and the region’s medical industry.
"It will not only significantly increase the availability of specialist neuroscience and radiosurgery treatments and provide better patient care but help attract and develop local and international talent. Investing in the new centre represents our continued faith in the resilience of the region’s economy, as well as a testament to our ongoing drive towards healthcare innovation in the UAE.”
