How Extended
Reality Is
Transforming
Surgery
T
hat nagging back pain has become
too intrusive to ignore. A patient has
tried conservative remedies like
NSAIDS and cortisone injections with
little success. They need surgery. But
they're worried. More than 4,000 preventable mistakes
occur in surgery every year, and at least 39
times a week a surgeon leaves foreign objects like
towels or sponges inside their patients, according to
a still-relevant 2012 study by Johns Hopkins.1
So they seek out an experienced, competent surgeon
who has successfully completed that particular
surgery many, many times. Surgeons in mid-career between
the ages of 35 and 50 with 10 years of experience
are the safest for patients, according to a peer-reviewed
study published in BMJ.2
But how did these surgeons actually get this experience
without harming their patients while they perfected their
technique? For many years, the solution has included training
simulators. Simulations reduce the risks associated with
surgical training by allowing novice surgeons the opportunity
to practice before applying their skills to a live patient.
Makes sense.
There are simulators for virtually every training need. For
instance, laparoscopic trainers are used to teach the intricacies
of gall bladder or colon surgery. But most traditional simulators
have limitations. For example, many simulators have
been criticized for presenting tasks that are too simple and
not closely related to real procedures.
So how can new surgeons safely hone their skills? The answer
lies in emerging technology with roots in the world of gaming
that seamlessly combines the physical and digital worlds.

Extended Reality a Boon to Medicine
The term virtual reality (VR) was coined back in 1982, referring
to a purely digital world. Users see and interact with
an environment that is entirely computer generated. By
contrast, augmented reality (AR) is a mix of the real world
with the virtual, combining elements of both with the goal
of enhancing how the real world is experienced. The complete
spectrum from VR to AR is referred to as mixed reality
(MR) or extended reality (XR). XR merges the real and digital
worlds and allows them to interact in real time.
Fueled by the availability of low-cost hardware, such as the
Oculus Rift and the Microsoft HoloLens, the field of XR has
seen explosive growth over the past several years as developwww.medicaldesignbriefs.com
