1. A method of treating a bone fracture comprising:
inserting a nail into an intramedullary canal,
wherein the nail comprises a distal area, a medial area, a proximal area, a transition portion, and a diameter taken in a plane perpendicular to a longitudinal axis of the nail,
wherein a head portion of the nail comprises the proximal area,
wherein a stem portion of the nail comprises the medial area and the distal area,
wherein only two openings in the head portion extend transverse to the longitudinal axis of the nail, each of the only two openings have an axis that extends transverse to the longitudinal axis of the nail, and the axes are parallel,
wherein a single opening in the medial area extends transverse to the longitudinal axis of the nail and is distal to the only two openings in the head portion,
wherein there are no openings in the distal area extending transverse to the longitudinal axis of the nail, and a distal one-half of the nail is free of an opening;
wherein the nail extends substantially an entire length of the intramedullary canal,
wherein the head portion has a larger diameter, the stem portion has a smaller diameter, and the transition portion tapers from the head portion to the stem portion,
wherein a fitting is disposed on the head portion at a proximal end of the nail, and the fitting is configured for receiving a tool for manipulating the nail,
wherein the nail comprises a distal end and a throughbore extending from the proximal end to the distal end along the longitudinal axis;
inserting a first anchoring member into the only two openings in the head portion; and
inserting a second anchoring member into the opening in the stem portion.
