A biomechanical study of greater tuberosity fracture fixation - comparing plate, screw, and suture fixation methods

The results when managing displaced humeral greater tuberosity fractures through conservative means are often disappointing. This biomechanical study, using porcine models, compares fixation of these fractures with locking plate, bridging suture and two-screws to determine which is the strongest, and to highlight suitable management options that can withstand the normal physiological forces through the shoulder joint. In addition, it is hoped that the results of this study can identify a less-invasive alternative to open surgery, without compromise of strength of fixation.
