Pacific Research Laboratories/Sawbones and Numalogics introduced a web application that allows orthopedic implant manufacturers to test devices on industry standard Sawbones bone surrogate (polyurethane foam), completely in a virtual environment. With the new web application, named ENDPOINT, engineers can now quickly test orthopedic screw designs using the latest computational modeling and simulation techniques and obtain results within days. This new testing method can reduce or eliminate device prototyping, saving the company time and money.
Customers can select the type of mechanical screw test to be performed, and, using a secure method, screw design drawings are uploaded into the cloud. An automated application then performs the simulation of the selected test, and results are returned to the customer within two days. Data security and confidentiality are maintained throughout the process.
Amy Posch, M.S. Design Engineer-Biomechanical at Sawbones, says, “We are happy to offer a CM&S tool that demonstrates a high level of credibility for axial screw insertion and pullout testing. Transparency in the models’ performance was important to convey and we are impressed with its verification and validation work. We look forward to expanding the biomechanical material suite available within this platform.”
Sawbones and Numalogics have worked collectively to develop robust virtual models of Sawbones polyurethane foam, the industry standard bone surrogate material for orthopedic implant testing, and to validate the existing virtual screw tests.
