Optical tissue stylet - observational study into vascular access in humans

The primary objective of the trial is to investigate if the optical tissue stylet technology can reliably discriminate intra-vascular (venous) from non-vascular punctures. Diffuse reflectance spectra will be acquired for these two situations, with…

Viscosity of PMMA Bone Cement in Percutaneous Vertebroplasty for Osteoporotic Vertebral Compression Fractures: A Randomized Controlled Trial

Establishment whether usage of high viscosity PMMA bone cement in PVP for OVCFs leads to a reduction in leakage incidence compared to usage of conventional (low-medium) viscosity PMMA bone cement in PVP for OVCFs.Since evidence is scarce or…
