From: Biomechanical evaluation of bone screw fixation with a novel bone cement
The tested bone screws: cortical (a) and cancellous (b) bone screws. The inner and outer diameters of the screws are for cortical (3.0/4.5 mm inner/outer diameter × 45 mm length) and for cancellous (5.0/6.5 mm inner/outer diameter × 45 mm length).
