Embodiment Construction

[0043] The humerus nail can include a nail body defining a nail longitudinal axis extending from a proximal portion to a distal portion. In some examples, the proximal portion of the humerus screw can include a plurality of through-holes formed through the body of the screw; for example, a plurality of proximal through-holes, descending through-holes, and calcar through-holes. In some examples, the descending through hole can define a descending screw track extending from anterior to posterior and proximal to distal. In some examples, the humeral screw can further include an ascending through hole defining an ascending screw track that intersects the descending screw track. In some examples, the calcar through-hole can define a variable-angle calcar screw track.

[0044] In at least one example, humeral screws can provide screw channels for targeting anatomical landmarks near the humeral head while also avoiding critical vasculature and nerves. Furthermore, providing these s...

Abstract

The humerus screw may include: a nail longitudinal axis extending from the proximal portion to the distal portion; a first proximal through hole defining a first screw track; a second proximal through hole defining a second screw track; a third proximal through hole defining a third screw track; a descending through hole defining a descending screw track; and a calcar through hole defining a calcar screw track. The first, second, and third screw tracks extend transversely to the longitudinal axis of the screw, the descending screw tracks extend from anterior to posterior and from proximal to distal, and the calcar screw tracks extend from distal to Extends laterally to proximally, anteriorly to posteriorly, and laterally to medially. In some examples, the calcar through-hole defines at least two calcar screw tracks.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 62 / 152,339, filed April 24, 2015, which is hereby incorporated by reference in its entirety. Background technique [0003] When using humeral nails to treat humeral fractures, it is important to be able to effectively target certain anatomical landmarks near the humeral head while also avoiding vital vasculature and nerves. Due to size and shape variations between each patient's anatomy, specific anatomical targets may vary in location between patients. Some conventional humeral screws do not effectively target the patient's anatomical landmarks. Contents of the invention [0004] To better illustrate the devices disclosed herein, a non-limiting list of examples is provided here: [0005] In Example 1, there may be provided a humerus nail comprising: a nail body defining a nail longitudinal axis extending from a proximal portion of the nail body to...
