Olecranon anatomy: Use of a novel proximal interlocking screw for intramedullary nailing, a cadaver study

Figure 1 Eccentrically aligned proximal interlocking screw.

Figure 2 Olecranon anatomy, related to a novel proximal interlocking screw for intramedullary nailing. A: Deepest point of the incisura olecrani; B: The point, which is 3.5 mm posterior to A point and targeted during insertion of the proximal interlocking screw; C: The point where the line from the middle of the medulla and the line perpendicular to point A intersect; D: Ideal entry point for intramedullary nail.
