Design and In Vitro Validation of an Orthopaedic Drill Guide for Femoral Stem Revision in Total Hip Arthroplasty

Klok, J.W.A. (author), Groenewegen, Jessica (author), Temmerman, Olivier (author), Van Straten, Niels (author), van Straten, Bart (author), Dankelman, J. (author), Horeman, T. (author)

Objective: Cemented total hip arthroplasty (THA) demonstrates superior survival rates compared to uncemented procedures. Nevertheless, most younger patients opt for uncemented THA, as removing well-fixed bone cement in the femur during revisions is complex, particularly the distal cement plug. This removal procedure often increases the risk...

From surgical waste to medical products

van Straten, Bart (author)

Hospital waste has a major impact on the environment. The worldwide growth of hospital waste is the result of the growing world population and the increase in use of disposables. A circular healthcare economy may contribute to the reduction of hospital waste. The circular economy is a system in which waste is prevented and where waste is reused....

Mondmaskers: van afval naar grondstof

Duijndam, J.M. (author), van Straten, Bart (author), Duzijn, Y.S. (author), van der Sijp, Joost (author), Lieshout, Michiel (author), Horeman, T. (author)

De totale zorg draagt naar schatting voor 5 tot 8% bij aan de totale CO2-uitstoot in Nederland. Dit wordt mede veroorzaakt door het grote verbruik van medische wegwerpproducten, die na gebruik verbrand worden. Onderzocht is of gebruikte chirurgische mondmaskers gerecycled kunnen worden om nieuwe medische producten te maken. Recyclen kan ervoor...
