Introduction: The screw biomechanical performance plays a crucial role on the early interfragmentary stability and, in turn, on the fracture healing outcome. To assess the biomechanical performance of the headless compression screws Fixos 4.0, 5.0 & 7.0 mm, interfragmentry compression force and pull-out strength were determined and compared to the Synthes 4.5 & 6.5 mm HCS. Materials & Method: I...
