An orthopedic computer simulator has been created by European scientists that may help implant surgeons to more precisely select implants for patients on an individual basis. The simulator takes inputs about the area of the patient that is to be worked on, as well as data about an implant, and provides an output of how the two will function together if the implantation occurs.
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 Lafuente [Dr. Ing. Ruben Lafuente, technical manager of the Spanish IT consulting firm Adapting S.L. and co-ordinator of the OrthoSim project –ed.]. “It was enhanced and complemented by a lumbar implant model provided by the Instituto de Biomecánica de Valencia in Spain.”
These 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.
Even better, the tool can be used to study the suitability of new implant devices and can help pinpoint any problems with the design at an early stage.
“Implant designers get the opportunity to test their new designs initially without the need for actual implantations,” notes Lafuente. “It will mean better implant designs at an early stage, cutting costs and research time, as well as improving outcomes early on.”
