Royal Brompton & Harefield NHS Foundation Trust has been increasingly implementing 3D Printing in its hospital services. The latest addition to their offer has been the ability to 3D print heart models based on Cardiovascular Magnetic Resonance (CMR) scans from their patients. And most innovatively of all, the Trust has developed a way of 3D Printing heart models that also show signs of scarring.
Patients suffering from Congenital Heart Disease (CHD) can benefit from the insights a 3D-printed model is able to provide their clinicians. Tangible models help the medical team to visualize and understand the complex anatomy of the patient’s heart. A first step in the process of creating a patient-specific model is segmenting the medical images. Dr. Nicholas Byrne et al. from Guy's and St. Thomas' NHS Foundation Trust in the UK examined the range of several cardiovascular segmentation processes and how much time each of these methods takes. The findings of this first systematic review are published in the JRSM Cardiovascular Disease journal.
Both high tibial osteotomy (HTO) and distal femoral osteotomy (DFO) procedures aren’t always straightforward and may require an alternative method to be adopted when planning for surgery. Innovative software and services are available to simplify the planning process and increase predictability of the surgical outcome.
At the Wilhelmina Children’s Hospital of the University Medical Centre of Utrecht, a four-year old patient with a large heart tumor came to pediatric cardiologist Dr. Blank for help. Due to the tumor, the boy suffered from heart rhythm problems, and it was quickly apparent to Dr. Blank that the only way to relieve these problems was to remove the tumor. The problem was its location. Situated near the mitral valve and the coronary arteries, the tumor would be extremely challenging to remove without damaging those delicate areas. Dr. Blank reached out to Prof. Hraska, a cardiac surgeon from the Sankt-Augustin hospital in Germany with substantial experience in removing similar tumors.
Dr. Peter Metherall is a registered Clinical Scientist and Chartered Engineer at Sheffield Teaching Hospitals NHS Foundation Trust, UK. As the leader of the new Sheffield 3D Imaging Lab, he is improving the clinical utility of Advanced Visualization and Quantitative Imaging for routine clinical imaging investigations and research applications. Materialise invited him to present at the Mimics Innovation Conference, and you can take a sneak peek of his work here. This post is the second in a two-part series.
From x-ray-based pre-operative planning and templating software to patient-specific solutions which employ 3D technologies, orthopaedic surgeons have access to an array of software and services to assist them when planning for successful surgical outcomes.

It is a sad day indeed when the happy tidings of a newborn baby are followed by the diagnosis of a serious congenital heart disease. Stephanie Starks had to face this situation 2,5 years ago after giving birth to her third daughter, Jemma. Although the disease was not recognized at first, little Jemma underwent two open-heart surgeries in the following 10 days and started treatment which she would need to continue for the rest of her life. Less than three years later, Jemma is now preparing for her fourth serious surgery.
The shoulder is a truly extraordinary joint, as it allows a full 180-degree range of vertical and horizontal motion. Unfortunately, the downside of this flexibility is that the more a joint can do, the more that can go wrong. The shoulder joint can wear out due to age, infection or trauma, leading to pain and a loss of function. When it comes to researching solutions to these problems, the shoulder surgeons at the Florida Orthopaedic Institute (FOI) and the researchers at the Foundation for Orthopaedic Research & Education (FORE) in Tampa, Florida, lead the way as one of the most reputable shoulder research collaborations in the world.
Making the world a better and healthier place was certainly the goal Materialise had in mind when they decided to donate a grant to the Centre for Rapid Prototyping and Manufacturing (CRPM) at Central University of Technology, Free State in South Africa. The grant allowed the CRPM to help some patients with life-changing interventions, and to introduce students to the benefits of using 3D printing in the medical field. One of the patients helped by the CRPM was a young woman of 32. She suffered from an ossifying fibroma tumor in her lower jaw. The surgical team decided it was necessary to immediately resect the tumor and place a custom-made laser-sintered titanium implant in the patient’s mouth.
