The effects of low-intensity pulsed ultrasound on bioabsorbable self-reinforced poly l-lactide screws

The effects of low-intensity pulsed ultrasound on the mechanical and molecular properties of self-reinforced poly l-lactide (SR-PLLA) screws were studied in vitro. SR-PLLA screws of 4.5 mm diameter were exposed on low-intensity ultrasound for 1, 3, 6, 9, and 12 weeks. After exposure, the bending str...
