The hypothesis of this study was that the extent bone regeneration could be enhanced by using scaffolds with appropriate geometry, and such an effect further increased mimicking natural timing appearance morphogenetic proteins BMP-2 BMP-7 after fracture. Bioplotted poly(ε-caprolactone) (PCL) disks four different fibre organizations were used to 3D scaffold architecture on healing defects in a rat pelvis model. Moreover, one PCL construct modified introducing nanoparticulate sequential...

To compare four different atlantoaxial stabilization techniques.Eight human cervical spines (segments C0-C3) were tested in flexion/extension, lateral bending and axial rotation. Range of Motion (ROM) at a 1.5 Nm load was recorded. After native testing, the Harms (HARMS), pars screw (PARS), intralaminar (INTRA) anterior transarticular (ATA) constructs applied random order.FLEXION/EXTENSION: mean ROM (±SD) state 15.9° (± 7.6°); HARMS 3.6° 2.0°); INTRA 5.5° 2.7°); PARS 2.8° 1.6°); ATA 3.7°...
