RESEARCH

Biomechanics and Mechanobiology (BMMB) is one of the eight Research Areas of BCN MedTech. It settled at UPF in 2015. Research at BMMB focuses on the load-bearing organs and tissues of the human body in health and disease, and it targets (i) the interactions between tissue multiphysics and biological processes, (ii) the multiscale regulation of organ functional biomechanics, (iii) the identification of mechanistic risk factors associated with different diseases and disorders, based on synthetic data and on the virtual augmentation of real world data.

Numerical methods that combine different modelling and simulation techniques are used to describe both the tissues at the organ level, and the tissue-cell interactions at the tissue and cellular levels. Models are usually developed to admit real world biological and/or clinical data as inputs, in addition to mechanical data from motion analyses where relevant. Theoretical and numerical concepts are tested against in vivo and in vitro data, allowing mechanistic interpretations of both experimental and clinical evidences, in addition to model validations.

On the one hand, emphasis is given in the study of the multiscale transfer of mechanical effects from the system level to the cell level in different scenarios, e.g. simulated treatments, organ/tissue condition or cell cultures; relative to a chosen reference state. On the other hand, advanced tissue models are used to link observable phenotypes to possible mechanisms of spatiotemporal tissue regulation that will depend on the prediction of different cell microenvironments. Both top-down and bottom-up approaches are adopted, to eventually apprehend the regulation of highly multifactorial diseases and disorders.

ANDAMIO (RTC2019-007413-1)

will predict, from 2D DXA images, the risk of osteoporotic fracture in 3D in the lumbar spine. The predictive algorithm will rely on biomechanical simulations that integrate the bone morphology and quality, external and internal loads, and the influence of soft tissues. The software will integrate the 3D-SHAPER technology, and use 3D-SHAPER outputs to:

  • Generate a 3D biomechanical model of the patient's lumbar spine,
  • Simulate several external load conditions, and calculate boundary loads on the vertebrae
  • Compute the distribution of stresses and strains in the vertebrae, and
  • Provide the medical doctor with an estimate of the risk of femoral fracture

The ultimate clinical goal for ANDAMIO is to predict at least 80% of osteoporotic fractures. In the case of successful clinical validation, the technology will be integrated into a commercial software version that will be personalized to be compatible with machines of the main leaders of the market.
