Table 1 Length (mm) and descriptions of the screws and blades for the PHILOS plates and Fx plate configuration groups. Emboldened cells correspond to where combination differs from the control. Types of screws, cancellous, cortical locking and cortical compression, are denoted by CA, CO-L and CO-C, respectively
From: Biomechanical comparison of screw-based zoning of PHILOS and Fx proximal humerus plates
