A high-tech bone implant may radically enhance the mobility of amputees.
Historically, prosthetic limbs connect to the physique with a fibre socket that makes use of suction to grip to the stump, however it’s typically ill-fitting, leaving the pores and skin irritated and liable to an infection.
Now NHS medical doctors at St George’s Hospital in South London are performing a brand new process, which permits prosthetic legs and arms to anchor into the bone.
Surgeons insert a titanium implant into the stump, leaving a piece protruding by the pores and skin. This may then be simply hooked up to the prosthesis through a robust magnet. And this in flip boosts the wearer’s mobility by enhancing the limb’s rotation.

The primary affected person to bear the brand new operation, often called osseointegration, has described the end result as a ‘huge improve’.
Marc Collins, 60, from Ashford in Surrey, misplaced his left leg on account of a motorcycle accident in 1979.
Since then he has had dozens of various kinds of prosthetic limb, most of which have used sockets.
‘These left me with numerous agonising sores that had been so painful I could not use the limb,’ says the married social care employee. ‘I am delighted to not should put on a socket any extra.’
The expertise has beforehand been utilized by British navy surgeons, says Alex Trompeter, orthopaedic surgeon at St George’s Hospital.
He provides: ‘It was clear that these sufferers had been recovering sooner and skilled fewer problems and infections which might be typical of the standard procedures.’

The operation takes between two and 4 hours. First, the stump is opened up and surgeons connect the titanium implant to the bone.
A small magnetic connector protrudes by the pores and skin, which heals naturally round it.
‘It includes a latch that the prosthesis clips on to – a bit like how an iPhone connects to its charger,’ says Professor Munjed Al Muderis, one of many orthopaedic surgeons who developed the process.
‘Osseointegration is like placing on a pair of slippers, versus lacing up a pair of shoes. It could possibly take as much as half an hour to make a standard prosthetic limb match utilizing the suction gadget, whereas this one merely clips in. This expertise is about to revolutionise the best way that we deal with amputees.’
