Preliminarily fix the humeral head split
When anatomic, step-less reduction has been achieved, perform preliminary fixation with 2 or 3 K-wires. While lag screws may provide better fixation these may be in the way of the angular stable plate screws. Thus, K-wires, which can be easily changed, are preferable. If necessary, supplementary lag screws can be added for the humeral head fracture.
