A bone fixation device includes a rod including a first portion extending from a proximal side of the rod, and a second portion extending from the first portion, wherein the rod is inserted into a medullary canal of an ulna bone, the first portion includes a plurality of longitudinally displaced screw holes, having axes whereby at least two screws inserted into the screw holes extend in discrete directions into a metaphyseal portion of the ulna. The bone fixation device also includes a curved extension portion extending from the proximal side of the rod to capture an olecranon of the ulna. The device provides the benefits of an intramedullary nail and proximal tension band type fixation in a single device. The fixation device permits a minimally invasive treatment of proximal ulna fractures that may otherwise be under treated.
