Biomechics of plate fixation
WebThis study aims to compare the biomechanical stability of 3 different types of scaphoid fracture fixation in a scaphoid nonunion model. Methods: Thirty cadaveric scaphoid specimens were assigned to one of 3 different fixation groups: (1) single 3.0-mm compression screw, (2) two 2.2-mm screws, and (3) scaphoid plate.

The fixation of the fracture has to respect these requirements and has therefore to provide sufficient biomechanical stability.
