Pioneering in medicine means a fruitful meeting of science and technology that creates treatment methods that are more effective and less traumatic.
One such pioneering method in knee or hip replacement surgery is mixed reality holographic navigation.
“The aim of arthroplasty is to achieve an excellent surgical result, which will meet the expectations of the patients. This is achieved thanks to two factors: as much information as possible during the surgery and as little trauma as possible”, points out Dr. Spyridon Arbis, Orthopedic Surgeon, Director of the 5th Orthopedic Day Care Clinic with Digital Navigation Systems of Metropolitan General.
Both factors are related to the best possible visual contact of the surgeon with the target area of the operation. This means that the size of the intervention, incision and wound has until recently been dictated by the surgeon’s need to “see better”, resulting in:
• Forced injury to muscles, ligaments, tendons
• More blood
• More pain
• More days in hospital
• More recovery time
• Greater chance of hospital-acquired infections and complications
• More costs for patients and the insurance system
• Use of analgesic drugs
• Extensive intervention on the joint to fit the new prosthesis.
The advantages of new technology
Mixed reality holographic navigation gives the surgeon the unique ability of x-ray type vision, allows him to not disturb the tissues too much and with a small incision to see more through it, thanks to the holograms.
The new generation of supercomputers with artificial intelligence software is helping to enable 3D imaging of anatomy and preoperative planning for the first time. Before the surgery, imaging tests are performed, so that inside the surgery, with special helmets of new robotic system technology, which the surgical team “wears”, all the details of the physical anatomy are projected as 3D holograms on the retina of the eye and directly on the joint patient (realistic reality) as well as how the materials should be precisely placed (digital reality). This “realistic” and digital reality make up the mixed reality, the holograms, on which the surgery takes place.
What is the result of the method
The result is a minimally invasive operation with less trauma, faster recovery, avoiding complications and ensuring the patient’s return to his home on the same day of the operation. Knee or hip arthroplasties with mixed reality holographic navigation have been launched for a year abroad and for a few months in Greece.
“Studies from the USA, regarding day hospital arthroplasties, verify that they are associated with a greater than 30% reduced statistical profile of readmissions or complications at both three and six months after surgery, compared to arthroplasties performed with a three- and four-day hospital stay. However, in addition to the individual benefit, there is also a more general benefit from the application of the method, as many people each year no longer need a blood transfusion, a fact with very positive consequences for the country’s blood reserves”, concludes Dr. Arbis.
