HUMERAL NAIL

摘要

A humeral nail can include a nail longitudinal axis extending from a proximal portion to a distal portion, a first proximal through bore defining a first screw trajectory, a second proximal through bore defining a second screw trajectory, a third proximal through bore defining a third screw trajectory, a descending through bore defining a descending screw trajectory, and a calcar through bore defining a calcar screw trajectory. The first, second and third screw trajectories extend transverse to the nail longitudinal axis, the descending screw trajectory extends anterior to posterior and proximal to distal, and the calcar screw trajectory extends distal to proximal, anterior to posterior, and lateral to medial. In some examples, the calcar through bore defines at least two calcar screw trajectories.
