1. A bone nail comprising:
an elongated body having a proximal end and a distal end, the elongated body extending between a rear edge of the proximal end and a front edge of the distal end;
a cylindrical shaped proximal portion at the proximal end, the proximal portion having an outer diameter and a proximal outer surface, the proximal portion including a transverse bore for receiving an anchor member;
a medial portion having a crescent shape and having a medial longitudinal axis, a groove, and a medial outer surface, the medial portion defined by a first arc defined by the groove having a first radius and a second arc defined by the medial outer surface having a second radius different than the first radius, wherein the crescent shape is a cross-section of the medial portion defined by a plane that is perpendicular to the medial longitudinal axis;
the proximal portion including a proximal longitudinal bore extending longitudinally through the proximal portion from the rear edge and communicating with the groove in the medial portion, wherein the proximal longitudinal bore has a proximal longitudinal axis;
the distal end including a distal portion, the distal portion having a distal longitudinal bore extending from the front edge to the groove; and
the medial longitudinal axis of the medial portion offset from the proximal longitudinal axis of the proximal longitudinal bore such that a majority of the medial portion of the elongated body lies on one side of the proximal longitudinal axis of the proximal longitudinal bore, and the proximal outer surface of the proximal portion and the medial outer surface of the medial portion touch a common tangent.
