Photographs of clavicle load testing experiments. The clavicle repair constructs were mounted by embedding the sternal and acromial ends of the clavicle in customized potting blocks. The sternal potting block was fastened to the base of the Instron test cell, while the acromial potting block was mounted to a load cell on the upper crosshead of the Instron. Torsion was applied by rotating the acromial potting block with the clavicle oriented vertically (a), while bending was applied by displacing the acromial potting block downward with the clavicle oriented horizontally (b)
