SOFCOT, or the Congress of the French Society of Orthopaedic Surgery and Traumatology, is the biggest congress of its kind for the French-speaking world. Annually held in Paris, the trade show is the place to be for orthopaedic surgeons, giving them an opportunity to get up to date with the latest techniques, publications and technology.
When Dr. Noble, an orthopaedic surgeon specializing in total joint replacement at Palm Beach Orthopaedic Institute, FL, found himself without hard copy X-rays to plan his hip and knee arthroplasty procedures, he took a leap towards digital pre-operative planning.
Roughly 500 years ago, Andreas Vesalius was born in Brussels to a family of court physicians. During his lifetime, he revolutionized the field of anatomy, disproving theories that had gone uncontested for the past 1,300 years. We printed out a 3D model of a brain in homage to the enduring genius of Vesalius.
Dr. Ola Wiig, an experienced pediatric orthopaedic surgeon, was confronted with a very challenging deformity in a young teenager. Dr Wiig’s patient was suffering from severely reduced mobility as a result of an epiphysiolysis in her proximal femur, which caused her leg to be severely rotated outwards. This wasn’t just causing the patient pain, it was stopping her from being a normal teenager.
In a recent study in the Netherlands, all 12 patients who underwent an acetabular reconstruction of large Paprosky type 3 defects using the Materialise aMace custom acetabular cup, were recorded as being satisfied with the results of their procedure. The study, by Marieke Baauw, MD, Gijs Gerard van Hellemondt, MD and Maarten Spruit, MD, PhD from the Department of Orthopaedic Surgery at Sint-Maartenskliniek in Nijmegen, the Netherlands reported on their use of the aMace as part of an integral approach which included “a detailed approach to defect analysis, including measurement of bone deficiency and bone quality”. As reported in Helio Orthopaedics, the study presents positive results from a follow up of the 12 patients at least 18 months after surgery.
Physicians around the globe have one goal in common, which is to improve patient care. Materialise recently attended the first workshop on Surgical Morphology and Imaging of Congenital Heart Disease in Asia organized by the Cardiac Centre at KK Women’s and Children’s Hospital (KKH). As an academic medical center and teaching hospital in Singapore, KKH is taking 3D Printing technology advancements in medicine to the next level by training specialists from the region – using actual 3D-printed heart models from patients.
A five-year-old boy named Jojo from a village near Munich was diagnosed with a rare malignant tumor called Ewing`s Sarcoma. Usually found in the diaphysis (middle part) of long bones Jojo`s tumor was located in the distal part of his left femur and very close to the growth plate. Since tumor-endoprostheses are not available for such young children due to their small anatomical dimensions, an amputation or rotation plasty has to be performed in these cases.
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.
Today we read stories all the time about the insights that clinicians can gain from 3D-printed heart models, and the way they contribute to a successful treatment outcome and improved patient care. In this blog post we wanted to take a look at the early days of cardiac 3D Printing, and one of the first applications where the technology proved its value.
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.
