It has increasingly been recognized that electrical currents play a pivotal role in cell migration and tissue repair, process named "galvanotaxis". In this review, we summarize the current evidence supporting potential benefits of electric stimulation (ES) physiology peripheral nerve repair (PNR). Moreover, discuss piezoelectric materials context. The use these deserved great attention, as movement body or external environment can be used to power internally properties devices for providing...

ABSTRACT Current scientific evidence enhances the importance of anatomic restauration vertebral bodies with compression fractures aiming, as other human body joints, to obtain a biomechanic and functional spine close one prior fracture possible. We consider that reduction these is only completely possible using intravertebral expandable implants, restoring endplate morphology, enabling more adequate intervertebral disc healing. This enables avoiding osteodegenerative changes segment its...
