An Evaluation Of Total Navicular Implants: A Scoping Review, James Mcclure Hughes, Nicholas Belardo Obias, Amanda Killeen

School of Podiatric Medicine - Student Research

The aim of this study is to determine the efficacy and safety profile of total navicular implants based on current literature.

Navicular insults such as high-energy trauma, osteonecrosis, and Muller-Weiss syndrome may result in avascular necrosis or a critical sized bone defect, conditions that are highly difficult to manage given current treatment modalities. Total navicular implants may offer a solution to these problems. While 3D printing of implants remains investigational, its use in highly individualized cases involving the talus has had promising results with conditions like avascular necrosis, tumors, trauma, and arthritis. The navicular is unique in its attachments to …

Tissue-Like Fracture Toughness And Stress–Relaxation Ability In Pva-Agar-Based Hydrogels For Biomedical Applications, Ismael Lamas Jr., Bhuvana L. Chandrashekar, Cláudia C. Biguetti, Mohammad R. Islam

Mechanical Engineering Faculty Publications

Soft tissues exhibit remarkable stretchability, fracture toughness, and stress–relaxation ability. They possess a large water content to support cellular processes. Mimicking such a combination of mechanical and physical properties in hydrogels is important for tissue engineering applications but remains challenging. This work aims to develop a hydrogel that can combine excellent mechanical properties with cellular viability. The research focused on polyvinyl alcohol (PVA)/agar double-network (DN) hydrogels, fabricated by thermal gelation and freeze–thawing methods. Their mechanical properties were characterized through tension, compression, fracture, and stress–relaxation tests, and their cellular viability was measured through cytotoxicity tests. The results show that the PVA/agar …

Limbgod(Pat. Pending): Wearable Garment For Amputation Prevention, Naomi Choi Dpm, Mba, Phuc An Dinh Bs, Ms, Eric Lee Bs, Francois M. Lokenye Dpm

Approximately 1.6 million people in the U.S. have lower limb amputations, which is expected to double by 2050 (Wong et al.). Socio-economic factors: income, education, rural residency & race, impact amputation risk (Okesina et al.), with Black Americans 70% are more likely to undergo major lower limb amputations than white Americans, even after adjusting for care access & comorbidities (Feinglass et al., Holman et al., Regenbogen et al.). Within 5 years, up to 50% of first-time amputees require another amputation (Dilingham et al., Glaser et al.) & those with comorbidities face a 77% five-year mortality rate (Fortington et al.).

Development And Exploration Of A Z-Shaped Foot And Ankle Internal Fixation Plate, Rhaz Shaghaghi Paul, Ian Hames, Sean Rich

Williams Honors College, Honors Research Projects

This paper will detail the design process of developing a Z-shaped foot and ankle internal fixation plating system. Group 6: Plates for the Sole was made up of 5 team members, who worked together to accommodate their client’s request to complete a biomechanical analysis of a Z-Plate design and a construct a prototype. The Z-Plate’s purpose is to provide podiatrists with a new solution that can fit nicely on the small, irregular bones of the foot, while also remaining strong enough to withstand the forces and torques of the foot.
