Reduction of the humeral head
In cases of slightly displaced humeral head fragments one can abstain from a reduction and just fix the humeral head percutaneously with screws.
In cases of displaced humeral head fragments reduction can be achieved by moderate digital pressure or manipulation onto the humeral head.
If this is unsuccessful, one could try to achieve a better reduction with the help of periosteal elevator or a bone hook inserted into the glenohumeral joint through a small incision of the rotator cuff.
Temporary fixation of the humeral head
The reduction of the humeral head is temporarily secured using 2 or 3 K-wires (as illustrated), or cannulated screw guide wires.
