Fig. 5From: Augmented cerclage wire improves the fixation strength of a two-screw construct for humerus split type greater tuberosity fracture: a biomechanical studyThe two-screw construct augmented with a cerclage wire for the fixation of GT fracture. The distractive force produced by tightening of the augmented wire on the screws was directed against the subchondral bone of humeral head. Two screws were fixed in a divergent trajectories and perpendicular to the bone surfaceBack to article page
