Dr. Armstrong holds a Masters of Science in Tissue Repair and Wound Healing from the University of Wales College of Medicine and a PhD from the University of Manchester College of Medicine, where he was appointed Visiting Professor of Medicine. He is founder and co-Director of the Southwestern Academic Limb Salvage Alliance (SALSA).

Dr. Armstrong has produced more than 510 peer-reviewed research papers in dozens of scholarly medical journals as well as over 90 books or book chapters. He is co-Editor of the American Diabetes Association’s (ADA) Clinical Care of the Diabetic Foot, now in its third edition.

Armstrong was appointed Deputy Director of Arizona’s Center for Accelerated Biomedical Innovation (ACABI) and co-founder of its “augmented human” initiative, which places him at the nexus of the merger of consumer electronics, wearables and medical devices.

Dr. Armstrong was selected as one of the first six International Wound Care Ambassadors and is the recipient of numerous awards and degrees by universities and international medical organizations including the inaugural Georgetown Distinguished Award for Diabetic Limb Salvage. In 2008, he was the 25th and youngest-ever member elected into the Podiatric Medicine Hall of Fame. He was the first surgeon to be appointed University Distinguished Outreach Professor at the University of Arizona. He was the first podiatric surgeon to become a member of the Society of Vascular Surgery and the first US podiatric surgeon named fellow of the Royal College of Surgeons, Glasgow. He is the 2010 and youngest ever recipient of the ADA’s Roger Pecoraro Award, the highest award given in the field.

Dr. Armstrong is past Chair of Scientific Sessions for the ADA’s Foot Care Council, and a past member of the National Board of Directors of the American Diabetes Association as well as a former commissioner with the Illinois State Diabetes Commission. He sits on the Infectious Disease Society of America’s (IDSA) Diabetic Foot Infection Advisory Committee and is the US appointed delegate to the International Working Group on the Diabetic Foot (IWGDF). Dr. Armstrong is the founder and co-chair of the International Diabetic Foot Conference (DF-Con), the largest annual international symposium on the diabetic foot in the world.

SICCO BUS

Dr. Sicco Bus is a human movement scientist and associate professor, principle investigator, and head of the Human Performance Laboratory at Amsterdam UMC, Academic Medical Center, department of Rehabilitation in Amsterdam, the Netherlands. He completed his PhD in 2004 on the biomechanics of the diabetic foot. Sicco is program leader and member of the board of the Amsterdam Movement Sciences research institute. He chairs the study group of Neurovascular Complications of Diabetes in the Netherlands, and is member of the editorial board and chair of the Prevention and Offloading working groups of the International Working Group on the Diabetic Foot, which is tasked with the development of clinical practice guidelines.

SPECIAL SESSION 1 - Diabetic Foot Biomechanics

Foot ulcers are one of the main lower-extremity complications of diabetes mellitus. Diabetic neuropathy changes the structure of the foot, affecting its function and, consequently, resulting in increased plantar pressures. These pressures are a predictive risk factor for the development of diabetic foot ulcers. Therefore, it is important to implement strategies to protect the foot from abnormal biomechanical loading. This special session will address the biomechanical aspects of the diabetic foot complications, advances in biomechanical assessments and new approaches to the prevention and treatment of foot complications in patients with diabetes mellitus.

Weight-Bearing CT

Date: April 14, 2021 | Time: 10:55am - 12:45pm (GMT-3)

FRANCOIS LINTZ

Dr. Francois Lintz, MD, MSc, FEBOT, is a board certified, fellowship trained, senior consultant orthopedic surgeon, specialized in the Foot and Ankle, practicing in the Center for Foot and Ankle Surgery in Union Private Hospital of Toulouse, France. His initial training was in France (Board Certification, DIU AFCP, 2007) and Britain (F&A fellowship with Pr Ian Winson, Bristol, UK, 2009). He also acts as Chair for the Scientific Committee in the French Foot and Ankle Association (AFCP) and member of the Media and Fellowship committees of the European Foot and Ankle Society (EFAS). His main focus in research has been the development of 3D-Biometric measurement tools for Weight Bearing Cone Beam CT. A cause which he serves now as Vice-President of the International WBCT Society.

ALBERTO LEARDINI

He is Director of the Movement Analysis Laboratory, Istituto Ortopedico Rizzoli – Bologna (Italy). His initial research focused on methodological issues and clinical applications of gait analysis, including also three-dimensional videofluoroscopy, radiostereometry, and surgical navigation. He then received a DPhil at the University of Oxford on mechanics and prosthesis design of the ankle joint. He is now exploiting additive manufacturing and medical imaging for custom-design of orthotics and orthopaedic implants. He is author of 170 papers in peer-review journals (H-index 40; 9700 citations) and of 4 international patents.

He has been President of Siamoc, Technical Group 3-D Analysis of Human Movement, and Italian Digital Biomanufacturing Network. He is in the Steering Group of the International Foot & Ankle Biomechanics community (i-FAB) since the foundation, in the Research Committee of the European Foot and Ankle Society, and in the Scientific Board of the Weight Bearing CT Society. He is now President – Elect of the International Society of Biomechanics (ISB).

SPECIAL SESSION 2 - Weight-Bearing CT

The foot and ankle are subject to a highly complex mechanical demand during daily living and sports activities: any biomechanical analysis shall therefore imply weight-bearing anatomical data. Recently, Weight-Bearing low dose Cone Beam Computed Tomography has enabled to obtain 3D representations and models of the foot and ankle under physiological load in daily clinical use as well as in the lab. This is a fundamental innovation which will strengthen clinical and biomechanical analyses. This special session will discuss techniques and applications of this new technology, both in research fields and clinical settings, for diagnosis, and for planning and assessment of treatments of foot and ankle disorders.
