Although indirect reduction with intramedullary (IM) nailing is the gold standard for long bone fractures, IM nailing in meta-diaphyseal fractures often results in malalignment. Placement of Poller (blocking) screws is an attractive and useful technique in these situations; however, the selection of accurate placement points and the placement process itself are often complicated. This paper proposes an intuitive, simple, and clear technique for selecting the location of Poller screw placement that can be used in either the anteroposterior or lateral view regardless of the fracture type and discusses techniques for Poller screw placement that enable displacement correction.
