[The Extended Deltoid-Split Approach for Plating Four-Part Proximal Humeral Fractures]

The deltoideopectoral approach is established as the gold standard in the surgical treatment of proximal humeral fractures. As an alternative, we demonstrate the extended deltoid approach with an intraoperative video. A direct lateral incision is performed and the anterior parts of the axillary nerve are identified and preserved. In our experience, this approach allows improved visualisation of the greater tuberosity and easier positioning of locking plates. Clinically relevant neurological injuries cannot be seen in our patients or in the literature.
