University of Geneve starts patients enrollment

by Martina Contin last modified 2010-11-26 12:25

The University of Geneve, in collaboration with the NeuroZentrum Zurich, has recently started a VPHOP clinical pre-trial with 30 patients which serves to validate a set of software tools the University of Bern has developed.

The software simulates the biomaterial flow during a special interventional treatment, called vertebral bone augumentation or vertebroplasty . This special data collection consists of two XperCT scans, one before the surgery and one after, and fluoroscopic images of the patients’ bones that are taken during the treatment. Patients have been selected only among those who already had scheduled a vertebral bone augumentation via vertebroplasty by the clinical centers.
The possibility to simulate the reaction of the vertebra bones after the introduction of biomaterial represents an important support for clinicians who may explore the effectiveness of the treatment and its biomechanical effects before testing the procedure on the patients.

The enrollment of patients has started with the VPHOP clinical data collection in May 2010, defining the advancing of the project from the development phase to implementation based on the technology assessment. The four clinical partners of the VPHOP consortium (Hôpitaux Universitaires de Genève, Switzerland; Charité - Universitätsmedizin Berlin, Germany; Istituti Ortopedici Rizzoli, Italy; and Institut National de la Santé et de la Recherche Médicale, Lyon, France) and their patients play a crucial role in demonstrating the clinical achievements of VPH technologies.

The clinical centers have been collaborating on a common VPHOP study protocol for the collection of clinical data that is required for predicting the risk of osteoporotic fracture. They are also participating in “special” clinical data collection protocols, such as the internventional treatment planning between the University of Geneve and the University of Bern, in order to validate and increase the predictive accuracy of the VPHOP technical models.
