Khalid, MA, et al. - Researchers intended to correlate the torsional failure strength of the humerus after subpectoral biceps tenodesis with an interference screw vs a unicortical button in a human cadaveric model. They randomized 13 matched pairs of fresh-frozen human cadaveric upper extremities to receive either 2.6 × 12 mm unicortical button or 6.25-mm interference screw subpectoral biceps tenodesis. The humeri were loaded into a material testing machine after the procedure. They further compared rotation angle to failure, failure torque, energy absorbed, and stiffness by paired t-tests with alpha set at 0.05. As per the results, in a cadaveric biomechanical model, at time 0, in comparison with a 6.25-mm interference screw fixation, the use of a 2.7 × 12-mm unicortical button fixation in biceps tenodesis resulted in higher loads needed to fracture the humerus in a torsion model.
