Less Complication through Computer Simulation

The OrthoSim platform is a system using computer software to create anatomical and implant simulations. The simulation models are based on the work of two leading European biomechanics research centres. “Our lumbar spinal region model is the result of over 20 years of research at the Laboratoire de Biomecanique of L’Ecole Nationale Superieure d’Arts et Metiers in Paris,” explains Dr. Ing. Ruben Lafuente, technical manager of the Spanish IT consulting firm Adapting S.L. and co-ordinator of the OrthoSim project.

The models were combined to provide a reliable simulation of the interface between the artificial implant and the living tissue, providing surgeons with vital pre-op information. “With this service, a surgeon or implant engineer can effectively call on the expertise of the best people in any field of orthopaedic surgery, where biomechanical simulation can offer new insights for patient care,” Lafuente says.

The models are linked together and are hosted at an online service. Integrating the various models and algorithms into a unified platform was a difficult computer science problem to solve. The OrthoSim project ended in March last year, with the research team successfully combining the various elements of the project. Since then the partners have been developing the service offering further and are looking for financial support.

“Initially we had a model just for lumbar spine implants, but in the last months we have almost completed a validated model for hip implants,” says Lafuente. “We believe that once we finish perfecting a model for knee implants we will have a very strong set of tools to offer surgeons.” But Lafuente warns that developing new products for the health market is a very difficult task in itself. “The quality assurance and validation issues are very important in healthcare directed products, and will require more work,” he says.
