Ian McDermott Discusses Patient-Specific Prostheses and 3D Printing for Knee Surgery

Posted on

Conformis-kneeIan McDermott is a Consultant Orthopaedic Surgeon and Founder of London Sports Orthopaedics. Ian was the youngest Elected Council Member and Trustee in the history of The Royal College of Surgeons and he currently holds an Honorary Professorship at Brunel University, London, in the School of Sport & Education. Ian specializes exclusively in knee surgery, and he is a designated ‘Center of Excellence’ for meniscal transplantation and also for the use of biological glues in cartilage replacement. Ian also specializes in high-performance partial and total knee replacement surgery, and in 2012 he was the first surgeon in the U.K. to implant a ConforMIS G2 patient-specific knee prosthesis. Ian has completed over 100 ConforMIS cases to-date, and he is now part of the ConforMIS Surgical Visitation Program, teaching other surgeons how to implant patient-specific knee prostheses.

3D Printing Orthopedic Solutions — Where are we? An Update.

Posted on

1-61bvtpvipel3dtujnbb_zgHealthcare is rapidly changing and by this, I mean that the technology of delivery and care is advancing faster than the providers, the insurers and the patients can keep up. We are going to be seeing a remarkable transformation over the next few decades that will benefit patients most, and much of this is due to advances in 3D printing.

Now, some of this already exists today. There are prototypes built everyday by manufacturers using this technology for research and development but only a handful have fully embraced this technology in medical device implantation for patients. For example, there are cutting jigs that are designed and printed based off the patient’s individual anatomy that act as guides for the surgeon to define bone margins and planned cuts or alignment principles during orthopedic surgery. Commonly, a CT scan of the patient’s bones and joints is visualized with landmarks identified that plot the proposed positions and cuts the surgeon is going to make to accommodate for the proposed implant. This can theoretically and practically simplify complex procedures in to a ‘paint by numbers’ solution.

Surgeon Calls On Materialise Mimics Software to Create 3D Printed Patient-Specific Surgical Guides for a Complex Wrist Osteotomy

Posted on

distal-radius-wrist-fracture-xraysAny type of surgery, from the simplest to the more complex, brings potential risks with it; any number of things can go wrong. That’s why Alistair Phillips, a Consultant Orthopaedic Surgeon specializing in the hand, wrist, and elbow who works at Spire Southampton Hospital and the Hampshire Hand Surgery Clinic, has a personal philosophy to treat his patients without surgery if at all possible. He only offers surgery as a medical solution if he honestly believes that it will improve a patient’s condition, with minimal risk involved. His goal is to keep patients in the hospital for as short a time as possible, which I’ve learned is often the goal of other physicians as well – the longer you stay in the hospital, the greater the risk of infection. 3D printing can often help with this goal, but not every surgeon goes straight to this technology as a first option.

Doctors 3D Printed a Replacement for This Woman’s Damaged Spine

Posted on Updated on

img-20170131-wa0020Human innovation continues to push forward in so many directions. In all walks of science, researchers are achieving new “firsts” in the pursuit of a better life for the people of the world. Now, doctors in India, a country that has been basking in its recent record-breaking satellite launch, have completed the nation’s first 3D-printed spinal restoration surgery.

The patient, a 32-year-old Indian woman, lost her ability to walk due to a severe case of tuberculosis. The disease commonly affects the lungs, but it traveled to the woman’s spinal cord when her immune system was particularly weakened by drugs she was prescribed for infertility. The tuberculosis compromised her first, second, and third cervical vertebrae, removing support for both her skull and lower spine.

Perfect-fit prostheses delivered on time

latticeimplant-12162026Bone cancer often means amputation for patients. If they are lucky, surgeons can remove the tumour and insert a prosthesis into the cavity that contained the bone. But the prosthesis may not fit properly and can loosen over time. This could lead to further pain and costs for patients who have already suffered both.

Fortunately, new research published in Physics Procedia opens the door to implants that are custom-made right in theatre. Prosthetic bones can be made using additive manufacture, more commonly known as 3D printing. This involves building the prosthesis one very thin layer at a time.

Milan Brandt and his colleagues at the Centre for Additive Manufacturing at RMIT University in Melbourne, Australia, have developed a technique for designing, 3D-printing and fitting personalised bone implants within a single operation. They rapidly image the cavity with a CT scan and 3D print a lattice that perfectly fits its shape. “Our novel tools require only a fraction of the time used by current prosthesis design methods,” Brandt says.

Currently, scientists and doctors 3D-print prosthetic bones using plastic and hydroxyapatite – a mineral found in natural bone. Brandt’s structures, however, are made from titanium – a light, durable and rust-free metal. The researchers fused layers of powdered titanium with a laser, a technique that operators can use to create any shape.

Brandt and his co-workers tested their procedure on a model bone made from plastic, which was as strong as real bone. They removed about 40 per cent of this fake bone to mimic a surgical operation and filled it with a 3D-printed lattice.

Betty Regains Mobility in Shattered Elbow with Medical 3D Printing

Posted on

1a64a5b0-3cf6-4624-a960-9e1129e7624d-originalBetty and her husband were about to leave on their annual holiday to Spain when they heard the bad news: her husband was terminally ill. The situation only got worse when Betty fell during the holiday and shattered her right elbow. Although she received medical attention, it was impossible to allow the bones to heal properly at a time when her husband needed all her care and attention.

She bravely weathered through the last months of her husband’s life, but after he passed away her arm was still not functioning properly and causing her considerable pain. It was time for Betty to heal, both mentally and physically. Production house Nieveranst filmed her gripping journey for RobTv.

3D-printed titanium revenue near $520 million by 2022

Posted on

3d-printing-medical-titaniumThe recent announcement that GE is acquiring a controlling stake in Arcam will have a profound impact on the additive manufacturing (AM) titanium sector. Arcam owns Advanced Powders & Coatings (AP&C), which supplies more than one-third of the total supply of titanium powder for the AM industry.

Because of this development and other important trends, SmarTech Publishing analysts believe it is an excellent time to reassess the market opportunities for 3D printed titanium, releasing “Titanium Opportunities in Additive Manufacturing – 2017.” According to the report, revenues from titanium-based AM power will reach $518 million in 2022 growing to $1,077 million by 2026.

The ability to effectively process titanium alloys is a leading driver in the development of titanium AM. Titanium is becoming one of the most popular materials for metal additive manufacturing systems due to their growing use in both medical and aerospace industries.
