  • Partial Lattice Defects in Higher-Order Topological Insulators. [Journal Article]
    Phys Rev Lett 2019; 123(26):266802Queiroz R, Fulga IC, … Cano J
  • Nonzero weak topological indices are thought to be a necessary condition to bind a single helical mode to lattice dislocations. In this work we show that higher-order topological insulators (HOTIs) can, in fact, host a single helical mode along screw or edge dislocations (including step edges) in the absence of weak topological indices. When this occurs, the helical mode is necessarily bound to a…
  • Intramedullary screw fixation for metacarpal shaft fractures: a biomechanical human cadaver study. [Journal Article]
    J Hand Surg Eur Vol 2020; :1753193419898066Labèr R, Jann D, … Calcagni M
  • Intramedullary cannulated compression screws have been introduced for the fixation of unstable metacarpal fractures. In the present study, this technique was compared with dorsal compression plating to evaluate its biomechanical performance in stabilizing metacarpal shaft fractures. In a first set of experiments, the biomechanical characteristics of the screws were analysed in an artificial bone …
